20220211988
This application relates generally to skin treatment, and more specifically, to apparatuses, systems and methods for treating a person's skin using one or more porous members, rollerballs and/or the like.
Abrasion of the outer layer or epidermis of the skin is desirable to smooth or blend scars, blemishes, or other skin conditions that may be caused by, for example, acne, sun exposure, and aging. Standard techniques used to abrade the skin have generally been separated into two fields referred to as dermabrasion and microdermabrasion. Both techniques remove portions of the epidermis called the stratum corneum, which the body interprets as a mild injury. The body then replaces the lost skin cells, resulting in a new outer layer of skin. Additionally, despite the mild edema and erythema associated with the procedures, the skin looks and feels smoother because of the new outer layer of skin. In some arrangements, skin can be treated by delivering one or more substances to the skin. In some instances, the application of suction along the skin surface can further enhance a skin treatment procedure.

As depicted in
According to some embodiments, as discussed in greater detail herein, the assembly 100 is configured to be selectively coupled to a vacuum or suction source. Thus, the tip, handpiece, cartridge or other fluid source and/or any other portion of the assembly 100 can include one or more fluid passages, openings, ports, valves and/or any other features to enable the vacuum or suction capabilities of the assembly 100. For example, the tip can include one or more suction ports that are aligned with one or more fluid conduits (e.g., internal and/or external passages) of the handpiece 110. As discussed in greater detail herein, any of the disclosed embodiments can include one or more features (e.g., peripheral lip, interior feature such as posts or cylindrical members, spiral members, abrasive pad or members, and/or the like) that are configured to selectively abrade tissue. For example, in any of the embodiments, the peripheral lip 124 can be configured to at least partially abrade and/or otherwise remove skin tissue when the handpiece assembly is moved relative to the skin surface.
Regardless of the exact fluid components that an assembly 100 comprises to enable it to selectively deliver a vacuum or suction force to the tip 120, the selective activation of such suction or vacuum can facilitate a skin treatment procedure and/or the use of the assembly. For example, in some embodiments, the use of suction can help with the delivery of fluids from a fluid source to the tip. In some embodiments, the use of vacuum can help create a seal between a periphery (e.g., lip) of the tip and the skin tissue, which in turn, can help with the delivery of fluids to the skin interface. As noted above, the use of a lip and/or any other interior members can assist with the at least partial abrading of tissue when the handpiece assembly is moved relative to a skin surface (e.g., especially when vacuum is being applied to the tip).
As illustrated in
In any of the embodiments disclosed herein or variations thereof, the tip and/or the entire handpiece assembly (e.g., especially in arrangements where the tip is not removable from the rest of the handpiece assembly) can be disposable. Thus, the tip can be configured for a single use prior to disposal. Accordingly, the tip can include one or more thermoplastic and/or other materials that are well suited for a single use application. Alternatively, the tip and/or other components of the assembly can include one or more metals, alloys, other rigid and/or semi-rigid materials and/or other materials that enable a user to re-use such items, as desired or required. For example, metallic and/or alloy-based tips (e.g., comprising stainless steel, titanium, platinum, etc.) can be configured to be autoclaved and/or otherwise sterilized between uses.
Further, as noted above, the tip 220 can include one or more abrasive features, surfaces and/or the like such that when the tip is moved relative to a targeted skin surface (e.g., especially upon activation of a vacuum source that draws the tip toward and/or engaged with the targeted skin surface), at least portions of the targeted skin surface can be selectively abraded or otherwise removed. For example, in some arrangements, the peripheral lip of the tip 220 can be configured to at least partially abrade or otherwise remove skin tissue when the assembly 200 is moved relative to a subject's skin surface. Such abrasive features or designs can be incorporated into any embodiments disclosed herein or variations thereof.

Further, in any of the embodiments disclosed herein or variations thereof, one or more materials can be positioned on, which, along and/or near the tip. In some arrangements, such materials are positioned along a cavity or similar retention member (e.g., an interior of a post or other interior member, another cavity or member along or near the tip, etc.), as desired or required. Such materials can be configured to at least partially dissolve or otherwise be released in the presence of water, other liquid or fluid and/or another diluting agent. In some embodiments, such materials are stored in porous or absorptive members and are configured to at least partially release from such members in the presence of a liquid. Accordingly, in such configurations, the various serums and/or other treatment materials that are desired to be delivered to a subject's skin surface for a particular treatment protocol can be embedded or otherwise located along or near the tip. Water, saline and/or another diluting agent can be advantageously delivered to the tip to selectively dilute and release the serums and/or other treatment materials to the subject skin. Additional details regarding positioning dissolvable or otherwise releasable materials on or near the tip of an assembly are provided in U.S. patent application Ser. No. 11/392,348, filed on Mar. 29, 2006, and issued as U.S. Pat. No. 8,048,089 on Nov. 1, 2011, and U.S. patent application Ser. No. 12/832,663, filed on Jul. 8, 2010 and issued as U.S. Pat. No. 8,814,836 on Aug. 26, 2014, the entireties of both of which are hereby incorporated by reference herein.

Further, as discussed in greater detail herein, the clearance or spacing between the rollerball 824 and the adjacent base surface 827 of the tip 820 can vary. For example, in some embodiments, such a clearance is about 1/128th to ½ inch. The rollerball 824 can be located within a housing that permits the rollerball to freely rotate and prevent the rollerball from being separated or otherwise removed from the tip during use. As noted herein, in some embodiments, the rollerball can be selectively removable from a particular housing of the tip, handpiece and/or cartridge (depending on which component of an assembly the rollerball is secured) for replacement, cleaning, maintenance and/or the like.
In any of the embodiments, disclosed herein, an assembly can include one, two or more rollerballs to facilitate the delivery or transfer of fluid from a cartridge, reservoir or other fluid source to the tip and the skin surface of a subject. The rollerball can be positioned along the longitudinal centerline of the assembly; however, in some arrangements, the rollerball is offset from the longitudinal centerline, as desired or required. Further, the rollerball can include one or more materials, such as, for example, metals or alloys (e.g., stainless steel, brass, titanium, etc.), thermoplastics and/or any other synthetic or natural material. The diameter (or other cross-sectional dimension) of the rollerball can be approximately ¼ inch to 2 inches. However, in other embodiments, the diameter or other cross-sectional dimension of the rollerball, wicking member and/or other member positioned along the distal end of a handpiece can be smaller than ¼ inches or greater than 2 inches, as desired or required.
According to some embodiments, the rollerball can include a solid (e.g., non-porous) structure or a porous structure, as desired or required. In any of the embodiments disclosed herein, the rollerball can include one or more coatings or other materials. For example, the rollerball can include one or more layers of dissolvable materials that are configured to dissolve and thus be released to the skin surface being treated in the presence of water or another diluting agent. In some arrangements, a rollerball comprises a porous structure that is at least partially saturated with one or more substances that are configured to be released (e.g., dissolve) during use. Such materials can be located, at least initially, within an interior portion of the rollerball. As discussed herein, the rollerball can be included in a system that is configured to generate a vacuum or suction at or near the tip, thereby enhancing the effect of using a rollerball or similar structure to engage targeted skin and/or delivery fluids to the skin surface. Further, the rollerball can be positioned adjacent a wicking member, porous member and/or other member that is configured to retain liquid. This can assist in ensuring that the rollerball maintains a certain degree of moisture, regardless of whether liquid would be otherwise immediately present at or near the rollerball.
In any of the embodiments disclosed herein, the rollerball and/or wicking member can comprise one or more abrasive and/or other roughened or sharp surfaces or features. Such embodiments can facilitate exfoliation of skin as the handpiece is moved along a subject's skin surface.

For example, as indicated in Table A above, in some embodiments, the initial step of a treatment protocol comprises one or more preparatory steps or procedures. For example, in some arrangements, the subject's skin is initially exfoliated, at least partially, regardless of the exact protocol being used. In some configurations, salicylic acid or other agent that will breakdown oils and dead skin tissue on the surface layers of the subject's skin can be selectively delivered to the skin of a subject. The delivery of such preparatory fluids can be performed using a device disclosed herein (e.g., a vacuum-assisted assembly). Alternatively, such materials can be delivered to the skin surface using one or more other methods or devices (e.g., topically applied without the use of separate device). In some embodiments, the delivery of fluids while suction is applied to the skin (e.g., via a suction-enabled assembly) can facilitate the delivery of fluids below the outermost surface of the skin to thereby enhance the initial preparatory step of a procedure or protocol.
With further reference to Table A, as a second step to a treatment procedure, a first treatment agents or combination of treatment agents (e.g., anti-oxidants, silver, benzyl peroxide, salicylic acid, sulfur, Avena sativa (oat) kernel extract, palmaria palmatate, horsechest nut, green tea extract, lipoic acid bioflavonoid, (Aesculus hippocastanum) horse chestnut, proanthocyanidin and a mixture of amino acids combined with sulfur and or benzyl alcohol or other penetrant enhancers and/or the like can be delivered to the skin via the rollerball, wincing material and/or the like.
Further, with continued reference to Table A, as a third step to a treatment procedure, a second treatment agents or combination of treatment agents (e.g., anti-oxidants, silver, benzyl peroxide, salicylic acid, sulfur, Avena sativa (oat) kernel extract, palmaria palmatate, horsechest nut, green tea extract, lipoic acid bioflavonoid, (Aesculus hippocastanum) horse chestnut, proanthocyanidin and a mixture of amino acids combined with sulfur and or benzyl alcohol or other penetrant enhancers and/or the like can be delivered to the skin via the rollerball, wincing material and/or the like.
With continued reference to
As discussed with respect to other embodiments herein, the use of vacuum or suction to help draw the tissue toward the rollerball or other distal member (e.g., wicking member, porous member, absorptive member, etc.) can help enhance a skin treatment procedure. For example, the ability to selectively delivery fluids and/or other substances or materials (e.g., included within the cartridge or other container that is physically coupled to and/or in fluid communication with a container, e.g., a multi-container manifold system) can be improved and/or otherwise enhanced by the use of suction or vacuum. For example, the application of a vacuum or suction force along the tip can help deliver fluids and/or other substances to the skin surface being treated at a controlled rate of delivery. This can be contrasted with embodiments that rely only on gravity to deliver fluids and/or other materials to the skin surface. The use of a vacuum or suction force (e.g., once a seal has been created between a distal lip or periphery of a tip or other distal portion of an assembly, in accordance with various embodiments disclosed herein), can help ensure that fluid and/or other materials contained within a container (e.g., cartridge) and/or other fluid system with which the assembly 2000 is in fluid communication (e.g., a manifold system) is consistently and adequately delivered to the targeted skin surface. This is applicable to and may be specifically adapted for any of the embodiments disclosed herein.
With continued reference to
As discussed with reference to other embodiments herein, the distal end of the assembly 2000 (e.g., the distal end of the handpiece portion 2110, the cartridge or other container 2040, a separate tip and/or any other component or portion) can include a peripheral lip or edge that is configured to contact the subject's skin. In some embodiments, such a lip and/or other periphery can help establish a seal with the adjacent tissue surface to ensure that, when a vacuum or suction source is activated, the targeted skin surface is engaged by the lip and/or other periphery. In some arrangements, this facilitates the delivery of fluids to the tip and removal of spend fluids and/or other debris (e.g., exfoliated skin) away from the tip.
With continued reference to
Thus, according to some embodiments, the rollerball or other member 2044 is resiliently biased in a distal orientation. In such configurations, the rollerball or other fluid delivery member 2044 is normally configured to form a seal 2062. As a result, in such a configuration, fluids and/or other materials (e.g., contained within a cartridge and/or otherwise in fluid communication with the rollerball or the fluid delivery member 2044) are prevented from exiting past the rollerball or other fluid delivery member 2044. In some embodiments, pressing or otherwise moving the rollerball and/or other fluid delivery member 2044 (e.g., wicking member, porous member, etc.) inwardly (e.g., against the force created by the spring 2050 or other biasing or resilient member) can create clearance between the rollerball or other member 2044 and the adjacent housing, thereby allowing fluid to flow around the rollerball or other member toward the distal end of the assembly 2000.
In some embodiments, however, if sufficient force is imparted upon the rollerball or other assembly 2044, the rollerball or other assembly 2044 can abut against a distal surface 2064 of the housing and/or other portion of the assembly to prevent further fluids and/or other materials from exiting toward the distal end of the assembly. Thus, in some embodiments, one or more resilient members (e.g., springs) 2050 can help regulate the passage of fluid from a reservoir (e.g., from within a cartridge or other portion of the assembly) to the tip of the assembly 2000, as desired or required. In some embodiments, the force that is applied against the spring or other resilient member 2050 regulates the amount of flow (e.g., flowrate) that moves past the rollerball and/or another fluid delivery member 2044 located along eth distal end of the assembly 2000. Such a configuration can be applied to any of the embodiments disclosed herein. In some embodiments, moving the rollerball and/or any other distal member 2044 too far against the biasing force may cause the rollerball or the member to seat against a proximal portion 2064 that will once again prevent flow from to the distal end of the assembly. Thus, in some embodiments, there exists a range within which the rollerball or other resiliently-biased member 2044 can be moved in order to regulate flow to the distal end of the assembly 2000.
As noted herein, e.g., with reference to, among other embodiments,
As illustrated in the cross-sectional view of
In some embodiments, with continued reference to
As discussed herein with reference to other embodiments, the depicted porous or wicking member 3044 can comprise one or more foams, thermoplastics and/or other materials. The cross-sectional size of the wicking member can be between ¼ inch and 2 inches or more. In some embodiments, the wicking member 3044 extends, at least partially, within the interior reservoir of the cartridge or other container. The wicking member 3044 can include any cross-sectional shape, as desired or required, such as, for example, circular, oval, square or other rectangular, other polygonal (e.g., triangular, pentagonal, hexagonal, octagonal, decagonal, etc.), irregular. In some embodiments, any of the porous members (e.g., wicking members) disclosed herein can be configured to transport liquids and/or other fluids through their structure via capillary action. In addition, the porous members (e.g., wicking members) disclosed herein can comprise one or more rigid and/or semi-rigid materials.
According to some embodiments, as illustrated in
In some embodiments, the tip 3020 or other distal member or portion of the assembly 3000 can include one, two or more suction ports and/or passages, as desired or required. The quantity, size, shape, orientation and/or other details about any suction ports/passages included on a tip can vary, depending on the particular design. In some arrangements, the vacuum or suction ports are located on the cartridge or other container 3040.
In some embodiments, the suction passages or conduits 3042 terminate at the distal end of the tip or other distal member 3020, as shown, for example, in
In some embodiments, the distal end of the tip or other distal member 3020 comprises a peripheral lip 3022 that is configured to create a partial or complete seal between the tip or other distal member and a skin surface when the tip 3022 is placed against the subject's skin during use. For example, a peripheral lip 3022 of the tip or other distal member or portion 3020 can extend outwardly so as to contact skin tissue and circumscribe an interior region 3023 of the tip during use. The lip can include a generally smooth outer surface (e.g., the outer surface that is configured to contact skin and form a seal relative to skin). In some arrangements, the use of vacuum (e.g., via activation of a vacuum or suction force, the couplings, connectors, conduits, channels and/or other members or features 3012, 3042 that place such a source in fluid communication with the interior region, etc.) is configured to draw the skin surface toward the tip or other distal member to at least partially seal it against the peripheral lip. The creation of such a seal and the delivery of a vacuum force along the interior region 2023 defined by the peripheral lip 3022 can facilitate the delivery of fluid from the cartridge 3040 or other container to the tip 3020. Further, the vacuum or suction force can cause skin located along the interior region 3023 of the tip or other distal member 3020 to be at least partially drawn within the interior region 3023 (e.g., toward the tip and the handpiece assembly). This can facilitate and/or enhance contact between the tip or other distal member 3020 and the skin surface being treated.
As noted above, in some arrangements, the creation of a vacuum or suction force along the interior region 3023 can advantageously permit enhanced fluid delivery from the cartridge or other fluid container 3040 to the tip or other distal member 3020. The amount of suction generated can be adjusted to modulate this effect (e.g., to regulate the amount of fluid delivered to the tip, the rate at which the fluid is delivered to the tip, etc.). In some embodiments, the use and generation of vacuum along the tip also advantageously facilitates the removal of spent fluid and/or exfoliated skin from the tip or other distal member.
In some embodiments, the peripheral lip 3022 and/or other interior abrading member(s) and/or feature(s) of the tip and/or other distal portion or member 3020 of the assembly 3000 can be configured to at least partial abrading of tissue when the handpiece assembly is moved relative to a skin surface (e.g., especially when vacuum is being applied to the tip). In some arrangements, the tip or other distal member can include one or more abrasive features, surfaces and/or the like (for example, one or more abrading members, spiral members, posts, abrasive surfaces, abrasive pads, etc.) such that when the tip or other distal member is moved relative to a targeted skin surface (e.g., especially upon activation of a vacuum source that draws the tip toward and/or engaged with the targeted skin surface), at least portions of the targeted skin surface can be selectively abraded or otherwise removed. Further, in some embodiments, the abrasion members or features (e.g., spiral interior members) can facilitate the extraction of at least one of blackheads, sebum and/or any other substances from the skin (e.g., with the assistance of the application of vacuum, twisting and/or other actions, depending on the protocol). Such abrasive members or features can be incorporated into any embodiments disclosed herein or variations thereof. In other embodiments, the handpiece assembly of
In some embodiments, the porous/wicking member 3080 positioned within the assembly 3000 is configured to at least partially contact the skin surface being treated during use. However, in other arrangements, as shown in
In any of the embodiments disclosed herein, the porous or wicking member 3080 can include one or more openings that extend through the porous/wicking member that are separate and different from the passageways inherently present in the porous structure itself. For example, such separate openings or passageways can extend at least partially longitudinally and/or radially along one or more portions of the porous member 3080. In some embodiments, such openings or passageways can be configured to convey water or other fluids through the porous/wicking member at a faster rate than through adjacent portions of the porous member. In some embodiments, such separate passageways can be configured to deliver air (e.g., continuously, intermittently, in a pulsed manner, etc.) to the skin surface. In other arrangements, the openings can be configured to deliver a separate fluid or other material (e.g., medicament, serum, other liquid or non-liquid material, etc.) to the skin surface during use. The diameter, shape, and orientation of the passageways and/or other openings can vary depending on the intended use, application and/or intended function or purpose, for example, to adjust the rate of flow of fluid or other substances through the porous/wicking member. In some embodiments, such passageways have a circular or curved cross-sectional shape. In some embodiments, they have an annular shape.
In some embodiments, one or more portions of the wicking or porous member 3080 can be at least partially hollow. In other arrangements, the porous member 3080 can be at least partially filled with substances, materials and/or structures, such as, for example, additional porous/wicking members having different properties than the first porous/wicking member, gels, solids, liquids and/or materials (e.g., either in loose form or in a contained manner, such as, in dissolvable or releasable capsules or other enclosures). In some embodiments, a porous member 3080 can include two or more passageways, other members and/or the like.
In some embodiments, as illustrated in
According to some embodiments, the internal reservoir or region 3084 is configured to store or otherwise contain one or more treatment materials (e.g., in solid, gel, liquid and/or any other form) that are configured to at least partially dissolve or be released in the presence of water or other liquids. Thus, as water or other liquids are drawn from the cartridge or other container 3040 through the porous member 3080 (e.g., via the application of vacuum or suction), materials contained within the internal reservoir 3084 and/or within other portions of the porous member (e.g., the rigid or semi-rigid portions of the porous member 3080) can be dissolved and carried to the tip-skin interface to enhance a treatment procedure. Such a configuration can simplify the manner in which serums and/or other treatment materials are delivered to the tip, can avoid having to store the treatment fluids within cartridges or other containers, can allow users to reuse cartridges and containers (e.g., by simply refilling them with water or another liquids) and/or provide additional benefits and advantages.
In some embodiments, the tip or other distal member 3020 is attached to the cartridge or other container by a press fit connection, friction fit connection, threaded connection, other mechanical connection and/or the like. In some embodiments, as shown in
In some embodiments, the porous or wicking member 3080 can be removable or replaceable and porous/wicking members with different properties (e.g., containing different materials) can be used. For example, porous members 3080 can be selected based on the materials they contain, their fluid transfer properties, other properties (e.g., absorbability, density, porosity, abrasiveness, etc.) and/or the like, as desired or required.
In some embodiments, the porous/wicking member 3080 is configured to contact skin tissue, for example, before or during use of the handpiece. In some arrangements, the porous/wicking member 3080 can include an abrasive structure or design (for example, one or more abrasive surfaces or features, such as, abrasive edges, members, etc.). In some embodiments, the tip or other distal portion of the porous/wicking member can include an abrasive surface or be otherwise configured to abrade tissue when the handpiece is moved relative to targeted skin tissue.
As noted herein, in some embodiments, positioning a porous member 3080 that is situated at least partially within a container (e.g., a cartridge) and extends to or near the distal end (e.g., to the tip) of the handpiece assembly 3000 can facilitate the transfer of fluids to the tip. In some embodiments, the transfer of fluids is enhanced by the use or porous materials or other structures (e.g., via capillary action), the generation of vacuum or suction along the tip and/or other factors.
In some embodiments, as illustrated in
In any of the embodiments disclosed herein (e.g., the assemblies of
For any of the embodiments disclosed herein, a cartridge or other fluid source configured to be used in an assembly (e.g., to couple to a handpiece), the cartridge can include two or more compartments that are fluidly isolated from one another. For example, in some arrangements, a cartridge includes two or three chambers, each of which is configured to store a different serum and/or treatment material to be used during a specific treatment procedure. In some embodiments, such a multi-compartment cartridge or other fluid source is separated by walls, baffles or other members or features. In some embodiments, a user can choose between the various compartments of the cartridge (and thus, the various serums and/or other materials to be delivered to the subject's skin surface) using one or more selection features, methods or devices. For example, the cartridge, handpiece, tip and/or other portion of the assembly can include one or more controllers (e.g., switches, levers, knobs, etc.) that permit a user to select the specific compartment of the cartridge from which fluids and/or other materials will be transferred to the subject's skin. In other embodiments, the orientation of the cartridge within the handpiece dictates which compartment will be in fluid communication with the assembly's internal passages and the tip. For example, the rotational or angular orientation of the cartridge relative to the handpiece can determine which compartment of the cartridge will be accessed by the rollerball.
In any of the assembly embodiments disclosed herein or variations thereof, the tip can be placed in fluid communication with a fluid manifold system. Thus, one or more fluids from such a manifold system or station can be selectively delivered to the assembly. Accordingly, in some embodiments, a dummy cartridge or a simple fluid conduit can be used (e.g. instead of a filled cartridge) to interface with such a manifold system or station.
According to certain embodiments, a cartridge or other container is placed in fluid communication with a manifold system that may comprise a plurality of individual fluid conduits. In turn, one or more of these fluid conduits can be in fluid communication with a separate container. For example, in some embodiments, such fluid conduits can be in fluid communication with containers of a tower system. In one embodiment, the individual fluid lines are in fluid communication with a main fluid conduit, which connects to a nozzle along a proximal end of a cartridge or other container secured within the handpiece. One or more of the fluid conduits can comprise a valve or other flow control device or feature to selectively regulate the transfer of fluids and/or other materials to the assembly. In the some arrangements, the manifold system comprises a total of four fluid branches. However, a system can comprise more or fewer fluid branches (e.g., 1, 2, 3, 4, 5, 6, 7, 8, more than 8, etc.), as desired or required by a particular application or use. Additional details regarding a manifold system or tower are provided in U.S. patent application Ser. No. 11/392,348, filed on Mar. 29, 2006 and issued as U.S. Pat.
