BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to devices and methods for incision closure and bringing together edges of a wound.

2.Description of the Related Art

A variety of devices are available for closure of surgical incisions, wounds and lacerations. Surgical sutures involve the use of a needle with an appropriate length of thread, depending on the shape, size, and location of the wound. Wound closure strips involve a surgical tape which pulls the patient's skin on either side of the wound together, thereby closing the wound. Wound strips and sutures are difficult to care for and to manipulate by both the patient and the medical professional applying them. Wounds located at joints in the body are particularly difficult areas to apply a wound closure device due to the inherent mobility of the joints.

Referring now to FIGS. 1A and 1B, one type of wound-closure device 100, includes a first component and a second interlaced component, each having an adhesive-backed wound-edge pad 102, 104 for attachment to a patient's skin adjacent to the wound or incision to be closed. Each of the wound-edge pads 102,104 is attached to an opposing tension adjusting pad 106, 107 that also has an adhesive backing. The wound-edge pads 102, 104 are connected to the respective tension adjusting pads 106 by elongate connecting elements 108.

The device 100 is used to close a wound or incision by following five general steps. The first step includes removing or peeling-off an adhesive backing at the back of the device (creating the structure of FIG. 1B), facing the patient's skin, thereby exposing a portion of the adhesive on underside of wound-edge pads 102, 104. Peeling off the adhesive backing results in separation of the first and second interlaced component. The first and second interlaced components can then be individually manipulated by the user. The first interlaced component is composed of wound-edge pad 102 and attached tension adjusting pad 106, and the second interlaced component is composed of wound-edge pad 104 and the attached tension adjusting pad 107. The exposed portions of the adhesive wound-edge pads 102, 104 are then individually adhered onto the patient's skin on either side of the wound/incision. The second step includes removing an adhesive backing from wound-edge pads 102,104 to expose the remainder of the adhesive underside of the pads 102,104, which are then adhered to the skin. Referring to FIG. 1A, the third step includes the user lifting the tension adjusting pads 106, 107 away from the patient's skin, and gently removing adhesive backing from each pad 106, 107. Step three includes the user pulling on the tension adjusting pads to close the wound. While maintaining this tensile force, the user lays down the adjusting pads causing the adhesive on the elongate connective elements 108 to adhere to the top surface of wound-edge pads 102,104. Finally, step five includes the tension adjusting pads 106,107 being snapped-off from the elongate connective elements 108. At the completion of device application, the wound-edge pads 102,104 on either side of the wound or incision, are connected only via the elongate connecting elements 108 . The elongate connecting elements 108 are relatively inextensible, and tension within these elements serves to keep the wound closed. See also U.S. Pat. No. 6,329,564.

However, there is a need for an improved wound closure device that provides better manipulation and control of the device while closing wounds located around joints such as the knee, hip, shoulder, and elbow.

Another advantageous structure may include, but is not necessarily limited to, one or more features that allow the wound closure device to stretch or elongate with the skin. The structure may comprise the addition of any number of slits or perforations on the wound pads.

Another advantageous structure may include, but is not necessarily limited to, one or more features that allow the wound closure device to stretch or elongate parallel to a wound line. The features may be reduced thickness zones between portions of the wound pads or between consecutive sets of wound pads. The two wound pad configuration may be further composed of, and amplified by, multiple consecutive wound pad configurations or sets wherein a film on the top of the wound pads is removed after the wound pads adhere to either side of the wound thereby permitting adjacent sets of the wound pads to move independent of each other in response to elongation or stretching of skin parallel to the wound line.

Another advantageous structure may include, but is not necessarily limited to, one or more features that allow the wound closure device to stretch or elongate both parallel and perpendicular to a wound line. The features may comprise the addition of cross-bars between adjacent elongate connecting elements such that the device can apply a compressive force across the wound whenever flexion or stretching parallel to the wound takes place. The wound pads may be further composed of multiple configurations, segments, or sets to facilitate stretching of the wound closure device parallel to the wound.

These and other features, aspects, and advantages of the present invention will become better understood upon consideration of the following detailed description, drawings, and appended claims.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIG. 2, there is shown a wound closure device 200, according to one embodiment of the present disclosure. The wound closure device 200 includes a first pad 202 having an adhesive disposed on a surface of the first pad 202, and a second pad 204 having an adhesive disposed on a surface of the second pad 204. Emanating from the first pad 202 is a first tension adjusting pad 206 having elongated and generally parallel connecting elements 208, 210 integrally formed with a first section 212. Similarly, emanating from the second pad 204 is a second tension adjusting pad 214 having an elongated connecting element 216 integrally formed with a second section 220. In some embodiments, the second tension adjusting pad 214 can have additional connecting elements, which can be generally parallel to each other, and that can extend from the second pad 204 and can be integrally formed with the second section 220. As illustrated in FIG. 2, the connecting element 216 of the second tension pad 214 is received between the connecting elements 210, 208 of the first tension adjusting pad 206, although other configurations are possible.

The wound closure device 200 also includes a tab 222 that is coupled to the first pad 202 and the second pad 204, and that is free of any adhesive. The tab 222 is located on corresponding edges of the first pad 202 and the second pad 204.

The tab 222 can be located below the first and the second tension adjusting pads 206, 214, and can be located above the adhesive surfaces of the first and the second pads 202, 204. The tab 222 or additional tabs connecting the first and the second pads 202, 204 together, can be placed at any location on the first and the second pads 202, 204, such as beneath or adjacent to the connecting elements (e.g., connecting elements 208, 210, and 216) of the tension adjusting pads (e.g., the first and the second tension adjusting pads 206, 214). Shown in FIG. 2, is an additional tab 224, which is identical to the description and placement of the tab 222.

As detailed above, the prior art wound closure device of FIGS. 1A-1B has limitations. For example, when the adhesive backing is removed at step one, the first and second interlaced components (e.g., the first and the second pads 202, 204) can move away from each other in an unconstrained fashion, making the manipulation and control of the FIGS. 1A-1B device challenging. This is particularly true when attempting to close relatively small wounds or when using a small sized device. Therefore, in one embodiment (e.g., FIG. 2) the first and the second pads 202, 204 are joined by one or more strips/tabs of non-adhesive material (e.g., the tabs 222, 224), which constrain movement of the first and the second pads 204, 208, and thus prevents separation of the first and the second pads 204, 208 following removal of adhesive backing that protects the adhesive surfaces of the first and the second pads 204, 208. The addition of the tab 222, or additional tab(s) (e.g., tab 224), makes the handling of the device much easier. As another example of an advantage, when the tension adjusting pads 206, 214 are pulled to close the wound, the tab 222 or additional tab 224, which are flexible, move away from the skin, for example by bending/folding upwards, to allow for wound closure. Once the wound closure device 200 is fully applied and the wound closed, the tab 222 or additional tab 224, bend upwardly, and can be trimmed-off, such as with a scissors or other shearing devices known in the art. In some embodiments, the tabs 222, 224 can include a polymeric material, which can be a plastic. In other embodiments, the one or more tabs 222, 224 are substantially perpendicular to a longitudinal axis defined by a wound line (such as 268 in FIG. 4B), where substantially perpendicular to can deviate a number of degrees.

Referring now to FIGS. 3A and 3B, a wound closure device 300 according to another embodiment is shown. The wound closure device 300 has a first pad 302, a second pad 304, and a first tension adjusting pad 306. The first pad 302 can have an adhesive disposed on a surface of the first pad 302. The second pad 304 can have an adhesive disposed on a surface of the second pad 304. The adhesive allows the first pad 302 and the second pad 304 to stick to other surfaces of the wound closure device 300 as well as a patient whose wound is being closed. The first tension adjusting pad 306 can be coupled to the first pad 304, and configured to move the first pad 302 towards the second pad 304 when the first tension adjusting pad 306 is moved away the first pad 302. The first tension adjusting pad 306 can also have an adhesive disposed on a surface of the first tension adjusting pad 306 for securing the first tension adjusting pad 306 to the second pad 304. The first pad 302 can have a line of material weakness 322. The line of material weakness can be slits or a plurality of perforations. The slits can be located on an outer edge 324 of the first pad 302. The perforations can extend across the first pad 302, as shown in FIG. 4A, from the outer edge 304 of the first pad 302 to another opposite outer edge of the first pad 302. The slits and perforations can elongate the first pad 302 in a longitudinal direction 326 substantially perpendicular to the first tension adjusting pad 306. The first tension adjusting pad 306 includes connecting elements 308, 318 that are connected to a first section 355 that is removed during device application. Connecting elements 308, 318 are elongated and generally parallel to each other.

The wound closure device 300 can also have a second tension adjusting pad 314 coupled to the second pad 304. The second tension adjusting pad 314 can be configured to move the second pad 304 towards the first pad 302 when the second tension adjusting pad 314 is moved away the second pad 304. The second tension adjusting pad 314 can also have an adhesive disposed on a surface of the second tension adjusting pad 314 for securing the second tension adjusting pad 314 to the first pad 302. The second tension adjusting pad 314 includes connecting elements 310, 316 that are connected to a first section 366 that is removed during device application.

The wound closure device 400 includes sub components, for example, two or more wound closure devices 200, 201, which are similar or identical to the wound closure device 200 of FIG. 2, thus any discussion with regard to the wound disclosure device 201 also pertains to the wound disclosure device 201. The wound closure device 400 includes two wound closure devices 200, 201, as previously described. Thus, for explanatory purposes, the first closure device 400 includes a first wound closure device 200 having a first and second pads 202, 204, and the second closure device 201 includes a third and fourth pads, 232, 234. As illustrated in FIG. 4B, the wound closure device 200 includes a first and second tension adjusting pads 206, 214, as previously described above, although the second tension adjusting pad 214 includes a connecting element 218 emanating from the second pad 204 and integrally formed with the second section 220. As illustrated in FIG. 4B, the connecting element 216 of the second tension pad 214 is received between the connecting elements 210, 208 of the first tension adjusting pad 206, and the connecting element 208 is received between the connecting elements 216, 218 of the second tensioning pad 214. Shown also in FIG. 4B, each the corresponding section 212, 214 has been removed from the corresponding tension adjusting pad 206, 214, respectively (e.g., via a perforated line, or by shearing off the sections, after placement of the wound closure device 200 on the subject. As detailed above, the wound closure device 201 is identical to the wound closure device 200. Thus, similar components previously described above with regard to the wound closure device 200 also pertain to the wound closure device 201. For example, the wound closure device 201 has third and fourth pads 232, 234, which correspond to the first and second pads 202, 204 of the wound closure device 200. The wound closure device 201 also has a third and fourth tensioning pads 236, 244 corresponding to the first and the second tensioning pads 202, 204.

The wound closure device 400 includes one or more connectors (e.g., connectors 252, 254, 256, 258, 260, 262, 264, 266), which can couple various pads together (e.g., the first pad 202 to the third pad 232, etc.). As illustrated in FIG. 4B the wound closure system has eight connectors 252, 254, 256, 258, 260, 262, 264, 266, which are flexible. Four of the eight connectors, connectors 252, 254, 256, 258, couple the first pad 202 to the third pad 232 together, and the remaining four connectors, connectors 260, 262, 264, 266 couple the second pad 204 to the fourth pad 234. In some embodiments, and as illustrated in FIG. 4B, the connectors 252, 254, 256, 258, 260, 262, 264, 266 do not overlap.

When the wound closure device 400 (e.g., each of the wound closure devices 200, 201) are placed across a wound line 268, and installed as previously described, the longitudinal dimensions of each of the connectors 252, 254, 256, 258, 260, 262, 264, 266 are substantially parallel to the axis defined by the wound. Substantially parallel in this sense could be deviating 20 degrees, 10 degrees, 5 degrees, 1 degrees, any degree within this range, or other degrees. Also, when the wound closure device 400 is installed, the connectors 252, 254, 256, 258, 260, 262, 264, 266, which are flexible, allow the wound closure system to stretch or elongate parallel to the wound line 268 (e.g., during flexion/extension of a joint). Additionally, the use of reduced spacing between portions of the pads (e.g., between the first and the third pads 202, 232, etc.) can allow the wound closure device 400 to expand parallel to the wound edge 268. This can aid in comfort for the user, allowing the user to move, while simultaneously preventing reopening of the wound edge 268.

FIGS. 5A and 5B also show a wound closure device 500, according to some embodiments of the disclosure, with a slightly different configuration for the one or more connectors. Thus, any discussion with regard to the wound disclosure device 500 also pertains to the wound disclosure device 400. Additionally, the wound closure device 500 includes sub components, specifically wound closure devices 200, 201, and 203. The wound closure devices 200, 201 have been previously described and are identical to the wound closure device 203. Thus, the discussion above with regard to the wound closure devices 200, 201, also pertain to the wound closure device 203. The wound closure device 500 includes a connector 502 that couples two or more of the pads (e.g., the first pad and the second pad 202, 232), or two or more of the entire wound closure devices 200, 201, 203 together. The connector 502 can couple, for example, all of the pads together that are within each of the wound closure devices 200, 201, 203, and can be situated around the periphery of the pads within each wound closure device 200, 201, 203, or around the periphery of the wound closure devices 200, 201, 203. In this case, when the adhesive surfaces of the wound closure devices 200, 201, 203 are exposed (e.g., by removing an adhesive backing), they remain affixed and constrained together. Then, when the system is placed across the wound line 268, the connector 502 can be removed, which can both individualize the movement of each wound closure device 200, 201, 203, and can also allow individualized tensioning of each individual wound closure device 200, 201, 203. Another advantage of the connector 502, is the ability to have predetermined spacing between each individual wound closure device 200, 201, 203, when the wound closure device 500 is placed across the wound line 268, adhered to the individual, and the connector 502 is removed. In some cases, this can be desirable for uniform tensioning, or areas with curvature that may need additional areas of tensioning (e.g., a joint, a knee, an elbow, etc.). In other cases, the individualized and unconstrained movement of each wound closure device 200, 201, 203, allows the wound closure devices 200, 201, 203 to move and respond to localized regions of skin stretching. For example, during flexion, particular regions of skin within the skin region defined by a joint stretches in different magnitudes, particularly depending on the localized curvature.

As illustrated in FIGS. 5A and 5B, the wound closure device 500 can include a second connector 504, where the first connector 502 couples at least the first and the third pads 202, 232 together, and the second connector 504 couples the second and the fourth pads 204, 234 together. In other embodiments, the first connector 502 can couple together a portion of each of the wound closure devices 200, 201, 203, and the second connector 504 can couple together a portion of each of the wound closure devices 200, 201, 203. This can be advantageous, allowing a side of pads (e.g., the first and the third pads 202, 232) to be installed and adhered to one side of the wound line 268. Then when the side of pads (e.g., the first and the third pads 202, 232) is adhered, the first connector 502 can be removed. Then, the opposing sides of pads (e.g., the second and the fourth pads 204, 234) can be adhered to the opposite side of the wound line 268. After, the second connector 504 can be removed. In some cases, the connectors 502, 504 as described above, do not contact the adhesive surfaces of the pads, which can aid in the installation of the wound closure device 500 (e.g., via an easy removal of the connectors 502, 504). In some embodiments, the connectors 502, 504 as described above, can be a film, and the connectors 502, 504 can be connected to the top surfaces of the pads (e.g., the first pad, the second pad, the third pad, the fourth pad 202, 204, 232, 234, respectively). The connectors 502, 504 allow adjacent pads (e.g., the first and the third pads 202, 232) to be attached to each other, thus resulting in a contiguous device (e.g., FIG. 5A). The one or more connectors 502, 504 (e.g., which can be film) are removed after adhering the pads within the wound closure devices 200, 201, 203 to either side of the wound. Thereafter, adjacent sets of pads (e.g., the first and the third pads 202, 232) can move independent of each other in response to elongation/stretching of skin parallel to the wound line 268.

Use of the prior-art device around joints such as the knee, hip, shoulder, elbow etc. poses unique challenges due to the relatively large amount of skin movement occurring during normal activities performed by the patient. When the knee joint flexes, the skin surrounding the incision undergoes significant elongation parallel to the incision. If the wound-closure device does not permit the skin elongation or restricts it, then the range of joint movement may be limited or the attachment of the device to skin maybe compromised. In prior-art device of FIGS. 1A-1B, the ability of the device to allow for such skin elongation is limited by the elasticity of the wound-edge pads. In one embodiment of the present invention, the ability of the device to stretch or elongate together with the skin, is facilitated by the addition of slits and/or perforations on the wound pads (FIGS. 3B, 4A). In another embodiment of the invention, the ability of the device to stretch or elongate parallel to the wound line is facilitated by use of reduced thickness zone/s between portions of the wound pads or between consecutive sets of wound pads (FIG. 4B). Yet another embodiment of the device is composed of two of more consecutive sets of wound pads, with a film adhering to the top of the pads. The film serves to keep adjacent pads attached to each other resulting in a contiguous device (FIG. 5A). This film is removed after adhering the wound-edge pads to either side of the wound. Thereafter, adjacent sets of pads can move independent of each other in response to elongation/stretching of skin parallel to the wound-line (see FIG. 5B).

Another challenge with use of prior-art devices around joints is increased forces experienced by the wound-closure device. As the joint flexes, the skin elongates not only parallel to the wound but also perpendicular to it. This results in increased forces acting across the wound line, which can compromise wound closure. To address this, in one set of embodiments of the invention an alternating connection is provided between the elongate connecting elements via the use of crossbars.

Looking at FIGS. 6A and 6B, there is shown a wound closure device 600 that includes a first pad 602 having an adhesive disposed on an undersurface of the first pad 602, and a second pad 604 having an adhesive disposed on an undersurface of the second pad 604. Emanating from the first pad 602 is a first tension adjusting pad 606 having elongated and generally parallel connecting elements 608, 610 integrally formed with a first section 612. Similarly, emanating from the second pad 604 is a second tension adjusting pad 614 having elongated connecting elements 616, 618 integrally formed with a second section 620.

At a distal end 632 of the connecting element 608 of the first tension adjusting pad 606, there is connected a first crossbar 642. At a distal end 634 of the connecting element 616 of the second tension adjusting pad 614, there is connected a second crossbar 644. At a distal end 636 of the connecting element 610 of the first tension adjusting pad 606, there is connected a third crossbar 646.

FIGS. 7A and 7B show a sequence of steps resulting in the formation of an alternating connection pattern between the connecting elements 608, 610, 616, 618 and crossbars 642, 644, 646 at the completion of application of the device 600. A first step includes peeling-off a release liner on the adhesive disposed on the undersurface of the first pad 602 and the second pad 604 thereby exposing a portion of the adhesive on the undersurface of the first pad 602 and the second pad 604. Peeling off the release liner results in separation of the first pad 602 and its connected first tension adjusting pad 606 and the second pad 604 and its associated second tension adjusting pad 614. Using the exposed portions of the adhesive of the first pad 602 and the second pad 604, the first pad 602 and the second pad 604 are then individually adhered onto the patient's skin on either side of the wound/incision 668. The second step includes peeling-off a release liner on the adhesive disposed on the undersurface of the first tension adjusting pad 606 and the second tension adjusting pad 614. The third step includes the user lifting the first tension adjusting pad 606 and the second tension adjusting pad 614 away from the patient's skin. Step three includes the user pulling on the first tension adjusting pad 606 and the second tension adjusting pad 614 in a direction away from the wound 668 to close the wound 668. While maintaining this tensile force, the user lays down the first tension adjusting pad 606 and the second tension adjusting pad 614 causing the adhesive on the elongate connecting elements 608, 610, 616, 618 to adhere to the top surface of the first pad 602 and the second pad 604. The first crossbar 642 is trapped underneath the connecting element 616. The second crossbar 644 is trapped underneath the connecting element 610. The third crossbar 646 is trapped underneath the connecting element 618. The next step includes the first section 612 and the second section 620 being snapped-off from the elongate connecting elements 608, 610, 616, 618 (see FIG. 7B).

Looking at FIG. 6B, when the joint flexes, causing the device 600 to stretch parallel P1 and perpendicular P2 to the wound 668, this arrangement of the connecting elements 608, 610, 616, 618 and crossbars 642, 644, 646 causes the device 600 to apply gentle compressive forces C across-the wound 668.

Referring now to FIGS. 8A and 8B, there is shown a wound closure device 800 according to another embodiment. The wound closure device 800 can include a first pad 802, a second pad 804, and a tension adjusting pad 806. The first pad 802 includes a line of material weakness 826 at an outer edge of the first pad 802 extending the first pad 802 in a direction substantially perpendicular to the first tension adjusting pad 806.
