Abstract: An implantable knee prosthesis includes a body having a substantially elliptical shape in plan and including a first portion and a second portion. The first portion includes a first peripheral edge and a first face. The second portion includes a second peripheral edge and a second face. The second peripheral edge extends radially outwardly from the first peripheral edge to form a shoulder between the first portion and the second portion.

Abstract: A prosthesis is provided for implantation into a knee joint compartment between a femoral condyle and its corresponding tibial plateau which is suitable for patients having large tibial defects. The prosthesis includes a hard body free of any means of fixation within the knee joint compartment. The body has a generally elliptical shape in plan and a pair of opposed surfaces including a substantially flat bottom surface and an opposed top surface.

Abstract: A prosthesis is provided for implantation into a body joint, such as a knee joint compartment between a femoral condyle and its corresponding tibial plateau, without requiring bone resection. The prosthesis includes a body having a generally elliptical shape in plan and including opposed top and bottom surfaces. The body includes a supporting portion and a coating portion, where the supporting portion has at least one surface at least partially disposed within an interior of the body and the coating portion has at least one surface disposed on an exterior of the body. The supporting portion is constructed from a higher modulus material than the coating portion such that the body is at least slightly deformable.

Abstract: A prosthesis is provided for implantation into a knee joint compartment between a femoral condyle and its corresponding tibial plateau without requiring bone resection. The prosthesis includes a body having a generally elliptical shape in plan and a pair of opposed surfaces where one of the surfaces is generally concave. The body further includes an exterior portion and an interior portion, where the exterior portion is constructed from a higher modulus material than the interior portion such that the body is at least slightly deformable.

Abstract: A self-centering meniscal prosthesis device suitable for minimally invasive, surgical implantation into the cavity between a femoral condyle and the corresponding tibial plateau is composed of a hard, high modulus material shaped such that the contour of the device and the natural articulation of the knee exerts a restoring force on the free-floating device.

Abstract: An implantable knee prosthesis includes a body having a substantially elliptical shape in plan and a pair of opposed faces. A peripheral edge of variable thickness extends between the faces and includes a first side, a second side opposite the first side, a first end and a second end opposite the first end. The thickness of the peripheral edge at the first side is greater than the thickness of the peripheral edge at the second side, the first end and the second end.

Abstract: An implantable knee prosthesis for unicompartmental implantation into a knee joint includes a body having a substantially elliptical shape in plan and a pair of opposed faces. A peripheral face extends between the opposed faces and has first and second opposed sides and first and second opposed ends. At least one aperture extends through the body and extends from a first one of the faces to a second one of the faces.

Abstract: An implantable knee prosthesis for unicompartmental implantation into a knee joint includes a body having a substantially elliptical shape in plan and a pair of opposed faces. A peripheral edge extends between the faces and has first and second opposed sides and first and second opposed ends. At least one keel member extends from one of the faces. A first dimension D is defined by the first and second ends. A second dimension F is defined by the first and second sides. The dimension F is from about 0.25 to about 1.5 of the dimension D.

Abstract: A knee prosthesis for unicompartmental implantation into a knee joint is implantable without requiring bone resection and includes a body free of any means of fixation to a portion of knee joint, anatomy and having a substantially elliptical shape in plan and a pair of contoured opposed faces including a convex face and a concave face. A peripheral edge extends between the faces and includes a first side, a second side opposite the first side, a first end and a second end opposite the first end. A first dimension D is defined by the first end and the second end. A second dimension F is defined by the first side and the second side. The dimension F is from about 0.25 to about 1.5 of the dimension D.

Abstract: An implantable knee prosthesis includes a body having a substantially elliptical shape in plan and a pair of opposed faces. A first one of the faces has a first shape and a second one of the faces has a second shape different from the first shape. A peripheral edge extends at an incline between the first face and the second face.

Abstract: An implantable knee prosthesis includes a two-piece body having a substantially elliptical shape in plan and including a first piece and a second piece. The first piece is a tibial piece including a tibial surface. The second piece is a femoral piece including a femoral surface. The first piece and the second piece are mutually slidably engagable and separable.

Abstract: The subject invention pertains to a control fascia adapted to be attached to one side of the blade of an ice hockey or street hockey stick. Ridges having a vertical component extending above the control fascia surface enable improved puck or ball control while offering freedom from unraveling, and minimum weight. The control fascias can be easily manufactured at low cost and are suitable for bearing logos or advertisements.

Abstract: Honeycomb materials having areas or volumes possessing different physical properties then the remainder of the honeycomb are prepared in a continuous process without requiring machining operations.

Abstract: Rapid production of thermoplastic sandwich structures containing fiber-reinforced or non-reinforced thermoplastic core, such as honeycomb, materials adhered to skins or facing sheets is accomplished by fusion bonding the skins or facing sheets to the core by means of thermoplastic film(s) heated to the melt temperature and applying sufficient pressure to fusion bond the skins or facing sheets to the core, followed, when necessary, by cooling the assembly to prevent overheating of the core and/or skins or facing sheets.

Abstract: Fiber-reinforced thermoplastic honeycomb is prepared in a continuous manner one half cell at a time by laying down a corrugated web of thermoplastic, with and without fiber-reinforcement atop a honeycomb, selectively fusing the node-antinode demes and repeating the process until a honeycomb of the desired depth is prepared.

Abstract: Shaped honeycomb parts are prepared in a continuous process wherein webs of fiber-reinforced or non-reinforced thermoplastic are slit in a predetermined manner such that the finished honeycomb may be separated by hand into parts having a predetermined geometry.
