The present inventions relate generally to the field of medical devices and the treatment of human medical conditions using the medical devices. More specifically, the present inventions include expandable prosthetic devices used for treating a variety of conditions, including rotator cuff injuries, broken and/or depressed bone fractures, infection and/or inflammation in the body.
Through repeated strenuous motion, sensitive soft tissues often suffer wear and tear injuries from repeatedly rubbing against one another and/or hard tissues, such as bone. Tears of rotator cuff tendons and articular capsule disintegration are examples of this type of injury. In addition, these tissues can be adversely affected by inflammation, infection, disease and/or genetic predispositions which lead to degeneration of these tissues.
Other bodily injuries, such as fractures of hollow bones (i.e. having medullar cavities) and depression fractures of vertebra require complex procedures for treatment, for example alignment and fixation of multiple bone fragments for the former and disc replacement for the latter.
Various solutions to problems in treatment of these injuries have been proposed, for example:
U.S. Pat. App. Pub. No. 2007/0198022 to Lang, et al., the disclosure of which is incorporated herein by reference, describes methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.
JP Pat. App. Pub. No. 2006-247257 to Yasuhiko, et al., the disclosure of which is incorporated herein by reference, describes a bone cement injector which is equipped with an injection tube and a balloon detachably mounted on one end of the injection tube, where the balloon is formed with a bioabsorptive material. Using the bone cement injector of this invention, the balloon is inserted into the damaged section of the vertebra to be treated, and subsequently the bone cement is injected into this balloon. Thereby, the bone cement can be injected into the corpus vertebra of the damaged part of the vertebra while preventing the blood from mixing in the bone cement and the bone cement from leaking into the vertebral canal.
U.S. Pat. App. Pub. No. 2005/0245938 to Kochan, the disclosure of which is incorporated herein by reference, describes a device for repair of intervertebral discs and cartilages in articular joints includes a catheter for inserting through a cannula, the catheter having a distal end and a proximal end and a lumen extending longitudinally therethrough. An expandable balloon may optionally be detachably attached to the catheter near the distal end. The proximal end of the catheter is coupled to an injector that holds a supply of a thermoplastic elastomer material at a predetermined elevated temperature sufficiently high to maintain the thermoplastic elastomer at a liquid state. The device allows a thermoplastic elastomer material to be injected into the intervertegral disc space or the articular joint space as a replacement prosthetic for the disc's nucleus pulposus or the joint's cartilage. This procedure is carried out percutaneously through the cannula.
U.S. Pat. No. 6,755,862 to Keynan, the disclosure of which is incorporated herein by reference, describes an intramedullary support strut for a long bone for a range of different applications including anchoring and fixation. The strut is in the form of nested telescopic members. In the retracted configuration, the strut is compact and may be inserted into position aligned with a shaft made in the medullary canal via a portal made in the lateral cortex of the bone. The strut may then be telescopically extended into the medullary canal to provide the required support.
U.S. Pat. No. 6,613,052 to Kinnett, the disclosure of which is incorporated herein by reference, describes an apparatus developed to enable a surgeon to perform multiple orthopedic surgical operations, such as orthopedic surgical resectioning, total joint replacement and fixation of fractures, based on a single reference point. The apparatus is adjustable to conform to the needs and dimensions of individual patients and the surgical procedure(s) to be performed. The apparatus includes a support adapted for insertion into and alignment within the medullary cavity of a patient's bone. The support is capable of expanding into the bone so that the support is fixed within the bone and alignable to the bone. The support may be implanted to align a fractured bone, or extend a distance beyond its fixed position within the medullary cavity to provide a known surgical reference point. The apparatus includes one or more cutting guides mountable on the support and used in performing the desired surgical procedure(s). The cutting guides are positionable with respect to the known surgical reference point created by the support which enables the user to accurately position and secure various instruments at the desired position about the patient's anatomy.

Non-limiting embodiments of the invention will be described with reference to the following description of exemplary embodiments, in conjunction with the figures. The figures are generally not shown to scale and any measurements are only meant to be exemplary and not necessarily limiting. In the figures, identical structures, elements or parts which appear in more than one figure are preferably labeled with a same or similar number in all the figures in which they appear, in which:
As described above, repeated strenuous motion often causes sensitive soft tissues to suffer wear and tear injuries from repeatedly rubbing against one another and/or hard tissues, such as bone. Tears of tendons and/or ligaments and articular capsule disintegration are examples of this type of injury. In addition, these tissues can be adversely affected by inflammation, infection, disease and/or genetic predispositions which lead to degeneration of these tissues.
Injuries to soft tissues such as tendons can cause pain and impaired function of the area served by the tendon. Typically, a bursa can be found near areas where “friction” injuries due to the rubbing are prone to occur. A bursa is a natural fluid collection that permits movements between tendons and/or ligaments and bone parts and prevents injury to these tendons by acting as a cushion and/or movement facilitator between them.
In some embodiments of the invention, prostheses described herein are shaped and/or sized to simulate the natural bursa found in the intended area of implantation. For example, in some of the rotator cuff embodiments described below, the described exemplary prostheses are shaped and/or sized to simulate the subacromial bursa. Optionally, the prostheses are sized to supplement a natural bursa which is misshapen and/or undersized, bringing the combination of the natural bursa and the prosthesis into line with the shape and/or size of a healthy bursa.
The rotator cuff is an anatomical term given to the group of muscles and their tendons that act to stabilize the shoulder and to permit rotation and abduction of the arm. Along with the teres major and the deltoid, the four muscles of the rotator cuff make up the six muscles of the human body which connect to the humerus and scapula. Injury to the tendons and/or these muscles can cause pain and impaired function of the shoulder. The subacromial bursa is a natural fluid collection that permits movement of these rotator cuff tendons beneath the acromion and coracoid process, both of which are part of scapula bone. In some rotator cuff injuries, the subacromial bursa becomes inflamed and suffers from a reduced ability to prevent injury to the tendons through friction.

In an exemplary embodiment of the invention, inflatable expandable prosthesis 202 is rectangular shaped when deflated and resembles a cuboid parallelepiped when inflated. In an exemplary embodiment of the invention, inflatable expandable prosthesis 202 is circular or oval in shape when deflated and when inflated resembles a cylindrical disc or ovoid. It should be understood, however, that many shapes could be adapted to be implanted between the acromion and coracoid processes and the rotator cuff tendons to prevent at least some injury to the rotator cuff and/or to permit relatively unhindered or free shoulder movement for a patient, in an exemplary embodiment of the invention. In some embodiments of the invention, prosthesis 202 is adapted to be inserted deflated into a patient's body through a cannula. Optionally, the cannula is a 5 mm-7 mm cannula. In an embodiment of the invention, a long axis 204 (x-axis) of inflatable expandable prosthesis 202 is approximately 2 cm to 10 cm in length when inflated. In some embodiments of the invention, a short axis 208 (y-axis) of inflatable expandable prosthesis 202 is approximately 2 cm to 7 cm in length when inflated In some exemplary embodiments of the invention, inflatable expandable prosthesis 202 is 0.5 mm to 20 mm in height (z-axis). Optionally, inflatable expandable prosthesis 202 is 1 mm to 10 mm in height. It should be understood that the deflated and/or inflated size of prosthesis 202 is adapted to fit for a patient's particular needs or to simulate the size and/or shape of the natural bursa, in an embodiment of the invention, and therefore, prosthesis 202 does not necessarily conform to the size ranges given above.
Inflatable expandable prosthesis 202 is manufactured by dip molding, in an exemplary embodiment of the invention. In some embodiments of the invention, inflatable expandable prosthesis 202 is a seamless balloon-like structure made from biocompatible and/or biodegradable synthetic materials such as, but not limited to, PCL, PGA, PHB, plastarch material, PEEK, zein, PLA, PDO and PLGA, or any combination and/or family members thereof.

Inflatable expandable prosthesis 202 is releasably attached to prosthesis implantation and/or inflation device 200, in an exemplary embodiment of the invention. Prosthesis implantation and/or inflation device 200 is adapted to inflate and/or deflate prosthesis 202, allow prosthesis 202 to be positioned in vivo, and/or separate from prosthesis 202 after implantation, leaving prosthesis 202 at the implantation site, in an embodiment of the invention. In some exemplary embodiments of the invention, prosthesis implantation and/or inflation device 200 includes a tube or catheter type structure 204 which interfaces with prosthesis 202 in the proximity of a sealing mechanism 206 which is located at the end of tube 204 nearest prosthesis 202.
In an embodiment of the invention, sealing mechanism 206 includes a plug 402, shown in
Rigid ring 412 is cast on tube 204 before plug 402 is cast tube 204 because in an exemplary embodiment of the invention, plug 402 has a larger diameter than the inner diameter of rigid ring 412 thereby preventing plug 402 from passing through rigid ring 412. In an embodiment of the invention, inflatable expandable prosthesis 202 is placed around plug 402 and tube 204 such that tube 204 and plug 402 extend into a cavity proscribed by prosthesis 202. Prosthesis 202 is attached to an exterior surface of rigid ring 412 such that air and/or other fluid injected into prosthesis 202 does not escape via the intersection of prosthesis 202 and rigid ring 412, in an embodiment of the invention. Optionally, a thermal method is used to attach prosthesis 202 to rigid ring 412.

In some embodiments of the invention, an anchoring expandable prosthesis is adapted to prevent and/or reduce injury to the rotator cuff and/or to permit relatively unhindered or free shoulder movement. The anchoring expandable prosthesis comprises an expandable member and at least one anchoring device which is adapted to be attached to a part of the patient, for example the humerus head/tendons, acromion and/or coracoid process, thereby anchoring the prosthesis in place. In an embodiment of the invention, the anchoring expandable prosthesis comprises at least one anchoring device attached to an expandable portion adapted to operate similarly to prostheses 100, 202. The at least one anchoring device is manufactured of biocompatible and/or biodegradable or non-biodegradable metals and/or alloys and/or composites, for example titanium, stainless steel or magnesium alloys. In an embodiment of the invention, the expandable portion is manufactured of biocompatible and/or biodegradable or non-biodegradable materials such as high density polyethylene or those described with respect to prostheses 100, 202. In an embodiment of the invention, the at least one anchoring device is attached to the expandable member using filaments and/or wires.
In some embodiments of the invention, prostheses described herein are adapted for anchoring, for example by contouring the outer surface such that surrounding tissues can be placed within the contours, thereby “anchoring” the device. In some embodiments of the invention, the contours are adapted to act as counterparts to anatomical features at the implantation site, whereby the features settle into the contours upon implantation, but still permit relatively unhindered movement of the treated area.
Prostheses 100, 202, and/or any of the other prostheses described herein, are adapted for use in places where there is sliding of soft tissues, such as tendons against other tissues, such as bones as: a) between the quadriceps and femur after operations on the knee, b) near the finger flexor and/or extensor to prevent adhesions, for treatment of ailments such as carpal tunnel syndrome or, c) between the skin and plantar fascia and calcaneus in case of calcaneal spur, in some exemplary embodiments of the invention. As described above, the prosthesis used for treatment of particular ailments is sized and/or shaped to simulate the natural bursa found at the location being treated, in an exemplary embodiment of the invention.
In an embodiment of the invention, an expandable prosthesis which is least slightly elastic, but not inflatable, is adapted to prevent and/or reduce injury to the rotator cuff and/or to permit relatively unhindered or free shoulder movement. In some embodiments of the invention, the elastic prosthesis is manufactured from polyethylene and/or silicon and/or in combination with metals, such as titanium. Optionally, the elastic prosthesis is contoured to serve as a counterpart to the surfaces with which it will come into contact. For example in the case of a rotator cuff, the elastic prosthesis may be contoured to fit at least the acromion.
In an embodiment of the invention, a prosthesis is provided which is substantially rigid. The rigid prosthesis is constructed of a biocompatible material, for example stainless steel and/or a hard plastic, in some embodiments of the invention. Optionally, the rigid prosthesis is also biodegradable. In some embodiments of the invention, the rigid prosthesis is adapted to act as a counterpart to at least one anatomical feature at the implantation site, whereby the feature mates with the rigid prosthesis upon implantation, but still permits relatively unhindered movement of the treated area. As an example, the rigid prosthesis is adapted to mate with both the humerus head and the acromion upon implantation, in an embodiment of the invention.

In some embodiments of the invention, the inflating gel and/or fluid contains pharmaceutical agents, for example anti-inflammatory drugs and/or antibiotics and/or pro-angiogenesis factors to promote healing, which are eluted into the patient's body. In some embodiments of the invention, prosthesis 202 is inflated to the maximum volume possible without reducing the shoulder's range of movement. In an embodiment of the invention, prosthesis 202 is filled to less than its maximum volume in order to permit shifting of the contents of prosthesis 202 during movement. Optionally, prosthesis 202 is filled to 60%-70% of its maximum volume (for example, an expandable member with a 14 cc volume is filled with 9 cc of filler). It should be noted that other prosthesis embodiments described herein are deployed in a similar fashion, in some embodiments of the invention.
Sealing (718) of prosthesis 202, once inflated to the desired level, is performed by pulling tube 204 towards rigid ring 412 as they slide in relation to one another plug 402 becomes lodged in a lumen 804 of rigid ring 412 and continued pulling brings rigid ring 412 into contact with counterforce ring 506, in an embodiment of the invention. In an embodiment of the invention, tube 204 passes through lumen 804 with lumen 804 providing fluid communication between prosthesis implantation and/or inflation device 200 and an inner space defined by the dimensions of prosthesis 202. In an embodiment of the invention, an attending medical professional performing the implantation procedure holds counterforce ring 506 substantially steady while pulling on tube 204 away from the patient. Optionally, prosthesis inflation device 200 is adapted to perform the steadying of counterforce ring 506 and/or retraction of tube 204 automatically. In some embodiments of the invention, a mechanism is provided to prosthesis inflation device 200 which translates rotational movement to a retracting force on tube 204. Optionally, rotation movement is applied manually.
Continued pulling (“retraction” away from patient) of tube 204 causes a portion of plug 402 to break off, the portion of plug 402 lodging itself in lumen 804 of rigid ring 412 thereby sealing prosthesis 202. In some embodiments of the invention, the portion of plug 402 becomes partially deformed as it lodges in lumen 804. Prosthesis inflation device 200, now being separated from prosthesis 202 as a result of sealing (718) is withdrawn (720) from the patient and patient is closed, in an exemplary embodiment of the invention. It should be understood that in some embodiments of the invention, a sponge-like expandable prosthesis device is used and therefore, inflation (716) and inflation related actions may not be carried out, for example prosthesis 100 expands rather than inflates.
In an exemplary embodiment of the invention, the implanted prosthesis is secured, using methods known in the art, to soft tissue and/or bone to prevent the prosthesis from being easily displaced by shoulder movement. In some embodiments of the invention, sutures, clips and/or anchors are used to secure the prosthesis in place. Optionally, an anchoring expandable prosthesis is used. In an embodiment of the invention, simulating a naturally occurring bursa using a prosthesis is an action taken with respect to method 700. Optionally, simulating is related to inflation (716) in that the prosthesis is inflated to resemble the appropriate size and/or shape and/or characteristics (malleability, compressibility, etc.) of the naturally occurring bursa. In an embodiment of the invention, placing the prosthesis at the implantation site and simulating a naturally occurring bursa does not significantly reduce movement of the soft tissues being protected in relation to the other tissues at the implantation site.
In an exemplary embodiment of the invention, prosthesis 100 is implanted by placing prosthesis 100 into a cannula, such as those described elsewhere herein, and advancing it to the implantation site using a plunger.
In an exemplary embodiment of the invention, prosthesis 100 or the elastic prosthesis, described above, is implanted by inserting the device directly through a small incision, without a cannula, near the implantation site.
It should be noted that the method shown and described with respect to

In an embodiment of the invention, device 1700 is provided with a safety 1712 at least to prevent over-inflation of a prosthesis attached thereto. Safety 1712 in some embodiments of the invention, is comprised of a ball 1714 and a spring 1716 whereby ball 1714 and backstop 1710 are adapted to be counterparts such that ball 1714 releasably fits into a groove on backstop 1710 shaped to receive ball 1714. In an embodiment of the invention, once canister 1702 is advanced maximally by depressing a trigger 1718, further force on trigger 1718 will cause safety 1712 to disengage backstop 1710 as a result of ball 1714 popping out of the groove on backstop 1710 as backstop 1710 moves towards proximal end 1708 under the effect of further force. It should be noted that once safety 1712 has disengaged backstop 1710 and therefore, syringe 1704 is no longer being provided with a counterforce, continued depressing of trigger 1718 results in at least a partial retraction of tube 204 and appurtenant parts. In an embodiment of the invention, device 1700 is adapted to be used by one hand of an attending medical professional.
