摘要:
A shoulder prosthesis (10) including a fracture stem has a body having an exterior surface, a shank (50) attached to the body (40) and a head (30). The body (40) includes a medial fin (42), an anterior fin (43) and a posterior fin (44). The medial fin (42) includes a suture hole (42a). The anterior (43) and posterior (44) fins each include a plurality of suture holes. The prosthesis further includes a lateral suture hole intersecting the exterior surface of the body (40). The lateral suture (45a) hole may be formed in a projection (45) on the lateral side of the prosthesis (10). In an alternative embodiment, a trail prosthesis includes indicia for noting the proper placement of the stem. The prosthesis includes corresponding indicia for replicating the placement of the trial stem.

A kit for preparing an intervertebral disc space for receiving an implant (100) includes a plurality of trials (152) having different sizes. Each trial (152) includes a body (154) insert ible into an intervertebral disc space, the body (154) having a leading end (162), a trailing end (164), a top surface (156) and a bottom surface (160), the top surface of the body having a first groove (176) formed therein. Each implant also includes a flange (166) secured to the trailing end (164) of the body (154), the flange (166) having a first channel (180) aligned with the first groove (176), wherein each of the different sized trials has a different flange thickness. The flange thickness controls advancement of a cutting tool such as a chisel (192) into the first groove at the top surface of the trial body, which controls the depth of the cut into vertebral bone.

A kit for repairing cystocele comprising a support apparatus comprising a substantially rectangular support member having two short sides and two long sides, a first end of said rectangular member at a first of said two short sides, a second end of said rectangular member at a second of said two short sides; a first strap connected to a first long side proximate said first end of said member; a second strap connected to a second long side proximate said first end of said member; a third strap connected to a first long side proximate a middle portion of said first long side; and a fourth strap connected to a second long side proximate a middle portion of said second long side, each of said straps comprising a connector configured to be coupled with a tip of a needle; a first needle configured to extend from an incision on a right side of a patient where a right adductor longus tendon of said patient inserts into a right portion of a pubic ramus bone of said patient, lateral to an edge of said pubic ramus bone, through a right obturator foramen of said patient, to an incision in a vagina of said patient; and a second needle configured to extend from an incision on a left side of said patient where a left adductor longus tendon of said patient inserts into a left portion of said pubic ramus bone of said patient, lateral to an edge of said pubic ramus bone, through a left obturator foramen of said patient, to said incision in said vagina of said patient.
摘要:
An implant for sealing and/or healing a defect in an annulus, comprising an area intended to encompass the defect. The implant is textile strip (6) that comprises a middle area (15) which is intended to encompass the defect and which is an oriented low-density embroidered structure for guided tissue ingrowth and reinforcement and end areas (14) adjacent to the middle area which are a high- density embroidered structure.

The present invention relates to implants used for alleviating and/or preventing conditions relating to damaged joints involving articulating surfaces. The implants com- prise fibre of polymer and/or metal, and can be used as an artificial joint, as part of an artificial joint or as an artificial joint spacer made to replace the missing cartilage or to improve the slidability between two natural and/or artificial components of the body, or between a natural and artificial component. The product of the invention can be used to partly or entirely coat medical products or to make up implants partly or entirely.

The invention relates to a variable height vertebral implant, comprising a first, essentially U or C-shaped cage and vertebral support surfaces (3) configured on said cage. The first cage is an inner cage (1) which is encompassed by a second, outer cage (8) and is guided telescopically. The limbs (10) of the inner (1) and outer cages (8) are aligned in such a way as to form a continuous lateral opening, and the inner (1) and outer cages can be fixed in relation to each other in a predetermined final position. According to the invention, the inner cage (1) has a longitudinal hole (12) in the area of the part connecting the limbs (10), said hole extending in the longitudinal direction and having toothing (13) on one side. An instrument with complementary toothing (32) interacts with this arrangement to move and adjust the cages in relation to each other. A threaded bore for fixing a desired adjusted position is also provided in the outer cage in a position below the area of the longitudinal hole.
摘要:
Disclosed is a method and a medical device comprising a bio-compatible polymeric product with a layered structure comprising at least one upper layer of a first polymeric component, a middle layer of a second polymeric component, and at least one lower layer of a third polymeric component, wherein the chain length of the first polymeric component and the third polymeric component is longer than the chain length of the second polymeric component. The medical device combines the features of strength, durability and bio-compatibility as well as it has resistance to tear and wear and has a good compressibility. A preferred design of the medical device is a cup produced from a core or film of LDPE surrounded by two layers of UHMWPE fabric. The medical device can be used as implants in mammals, especially as artificial cartilage within joints to secure mobility of the joint.
摘要:
Apparatus for positioning a prosthesis (60) in a bone includes a body (10), first and second clamps, a depth gauge (30) and a guide (40). The first clamp (20) is coupled to the body (10). The depth gauge (30) is coupled to the body (10) and is movable relative thereto generally perpendicular to the shaft of the bone. The second clamp (50) can be selectively engaged with and disengaged from the depth gauge (30). The second clamp (50) is movable with the depth gauge (30) and is also moveable in a direction generally parallel to the axis of the bone. The guide (40) is used to determine the proper rotational orientation of the apparatus. The first clamp (20) is then secured to the bone. The second clamp (50) is secured to a trial prosthesis and is engaged with the depth gauge (30) as the trial is inserted into the bone. When the proper insertion depth is reached, the second clamp is secured to the depth gauge. The joint is then reduced and the range of motion checked. The depth and rotational orientation can be adjusted as needed. The second clamp (50) is released from the trial, the trial is removed and the prosthesis (60) is inserted in the bone and secured to the second clamp.
