[/VVi/WWE SUBDERMAL TENDON IMPLANT SUMMARY OF THE INVENTION This invention relates to improvements in tendon surgery and more particularly, to improvements in a method andapparatus for repairing and reconstructing tendons.

Accordingly, a primary object of this invention is an improvedsubdermal tendon implant which is compatible with the surrounding body tissue.

A further object is an improved method and structure which substantially eliminates adhesions between the tendon and surrounding tissues preventing subsequential restrictive fibro- SIS.

Another object is an implant which is chemically inert and demonstrates a very low order of reactivity eliminating any incapacitating foreign body reactions.

Another object is a novel means for anchoring the sub dermal implant to substantially immovable tissue to prevent it from moving axially along the tendon.

Another object is a subdermal implant which keeps the tendon perfectly positioned under normal tension preventing lateral displacement of the tendon.

Another object is an improved structure which causes no restriction in movement or deformity allowing essentially full range of motion after healing.

Another object is an underlay and pulley which do not cause infection or extrusion and are resistant to absorption, hardening and degeneration.

Another object is an implant having nonwetting surfaces which minimize sticking or encrustation allowing the implant to act like a membrane permitting the tendon to move freely across its surface. 7

Another object is an improved method of constructing a subdermal implant which may be quickly positioned during the operative stage and is tough and durable after the operative stage.

Another object is a tendon implant which is adaptable to a variety of clinical situations including tendolysis, primary repairs, and secondary reconstruction and grafts.

Other objects and advantages will be apparent from the ensuing specification and drawings for this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In tendon surgery the problem of subsequential restrictive fibrosis due to adhesion is omnipresent and frequently severely limiting in clinical results. With this problem in mind, coupled with the knowledge that healing and restitution of tendons occurs almost solely from the surrounding tissue, research was begun. After extensive testing and obtaining data on various tendon accessories the subdermal tendon implant l0 disclosed in this application was developed. Then numerous laboratory experiments were conducted using the subdermal tendon implant with canine preparations and ultimately with specific clinical applications. The results were extremely favorable with both groups experiencing virtually no adhesions or fibrosis retaining essentially full range of motion. In addition no infections or extrusions developed during the postoperative period.

FIGS. 1 through 5 show the subdermal tendon implant 10 as it is used in tendon surgery on a finger. 12. FIGS. 6 through 9 disclose the implant in more detail and in particular show the process of making the implant. The subdermal tendon implant l0 basically includes a flexible sheeting 14 of chemically inert material sculptured to a desired size and shape with a mesh or netting 16 bonded to a surface of the sheeting material.

FIGS. 1 and 2 show an operative use of a subdermal tendon implant sculptured to form an underlay 18 taking the shape of an elongated member. The underlay preferably has a mesh or netting l6 bonded to an inferior surface 30 of the sheeting 14. The sheeting is approximately 0.020 inch thick and may be reinforced to provide added strength and prevent stretch. The underlay 18 may be fabricated or trimmed to a width of approximately 1.0 cm. and has lengths ranging from about 1.0 to 2.5 cms.

The underlay 18 is positioned under areas of tendon exploration or repair to eliminate adhesions and later anchorage. As shown in FIGS. 1 and 2 the surface containing the mesh or netting 16 is placed inferiorly against substantially immovable tissues 20 such as a bone or joint capsule. The mesh or netting material causes fibroblastic infiltration to occur thereby securing the implant 10 in place with periosteal attachment. This is extremely important as it allows the tendon to move across the underlay without causing displacement. It is also important to note that this leaves the nonreactive superior surface 22 of the sheeting material opposite the explored or repaired tendon 24.

FIGS. 3 and 4 show an operative use of the subdermal tendon implant l0 sculptured to the size and shape of a pulley 26. The pulley is also an elongated member having shackle end portions 28 linked together by a central portion. The pulley is sutured into place over the tendon 24 with the mesh or netting l6 bonded to the inferior surface of the shackle ends 28 as best shown in FIGS. 8 and 9. As is true with the underlay 18, the mesh material of the pulley causes fibroblastic infiltration to occur thereby securing the implant to adjacent body tissues.

The pulley 26 is fabricated from the same sheeting material as the underlay 18, however, the thickness of the material is normally less than that of the underlay and is about 0.007 inch. The lengths of the pulley 26 range from about 1.0 to 1:5 cms.

The pulley 26 is devised to aid tendon placement and balance keeping the tendon perfectly positioned under normal tension. In addition it should be noted that the portion of the pulley 26 touching the tendon 24 is nonreactive sheeting material keeping the tendon free of fibrosis or adhesion for the distance of excursion under the pulley.

FIG. 5 shows the operative use of both an underlay l8 and pulley 26 on a finger 12. It should be pointed out that the underlay and pulley may be used together as shown in FIG. 5 or may be used separately as shown in FIGS. 1 through 4. In addition the chemically inert surface of the sheeting material is always adjacent the tendon 24 with the surface containing the mesh material adjacent body tissues 20 such as the bones shown in FIG. 5.

FIGS. 6 through 9 disclose the subdermal tendon implant 10 in more detail. In particular FIG. 6 shows a top view of the inferior surface 30of an underlay 18 with the mesh or netting l6 bonded to the flexible sheeting.

The sheeting I4 is preferably made from a chemically inert material which is compatible with the human cellular structure. In addition it is preferable that the sheeting 14 have nonwetting surfaces which minimize sticking or encrustation. Further the material should be resistent to absorption, hardening and degeneration and as previously mentioned contains the quality of nonadherence to tissue. A flexible silicone elastomer manufactured by Dow Corning sold under the trademark Silastic has been found to substantially .meet the above-mentioned qualifications. In addition other medicalgrade silicone elastomers, or materials similar to Silastic, or equivalents thereof have been found as satisfactory material for the sheeting.

As previously mentioned the sheeting 14 is preferably reinforced with a polyester material or similar synthetic fiber to eliminate stretch and permit suture attachment.

FIG. 7 shows in detail the process of making a subdermal tendon implant 10. The sheeting 14 is fabricated or sculptured to the desired size and shape and the mesh 16 is bonded to a surface of the sheeting by an adhesive 32; The adhesive is preferably a medical adhesive such as silicone adhesive. When this is completed the implant is ready to be placed subcutaneously with the smooth, nonreactive superior surface 22 of the sheeting adjacent the repaired or explored tendon and the inferior surface 30 containing the mesh material adjacent body tissues for rapid fixation. I

FIG. 8 shows a pulley 26 with mesh 16 secured to the inferior surface of one of the shackle ends 28. The mesh 16 to be secured to the other shackle end 28 is shown in FIG. 9 and may be made from polyester netting or similar synthetic fiber. As mentioned previously the polyester netting causes fibroblastic infiltration through the mesh 16 thereby securing the implant to adjacent tissues. g

The use, operation and function of this invention are as follows:

After constructing this invention the subdennal tendonim 7 plant 10 is ready for use in tendonrsurgery. The nonreactive sheeting surface 22 is positioned opposite the explored or repaired tendon while the mesh surface 30 is placed inferiorly against adjacent tissues for rapid fixation. In particular, the subdermal pulley 26 is suturedirito place over the tendon 24 as shown in FIGS. 3, 4 and 5 while the subdermal underlay I8 is placed under the tendon 24 and sutured into place as shown in FIGS. 1 and 2. It is important to note that the subdermal tendon implant will be firmly attached via the bonded mesh 16 by the third postoperative week.

The subdermal implant 10 provides a medical device which is adapted to keep the tendons perfectly positioned and free to fibrosis or adhesions. In addition the implants do not cause infections or extrusions while permitting the patient to retain essentially full range of motion after the operation.

In addition to being safe and free from incapacitating foreign body reaction the subdermal implant may be quickly positioned during the operation with results that are more reliable than previous experiences with autogenous fascia or connective tissues. Further the invention described in this application may be utilized for a wide variety of difficult clinical situations, including tendolysis, primary repairs and secondary reconstruction or grafts.
