International Classification:

A61F 2/32

US Classification:

623 2222

Abstract:

A prosthetic device for replacement of a hip bone that includes an acetabular component configured to connect to a femoral implant and a pubis member. The pubis member connects to the acetabular component and includes a clamping portion that is configured to attach to an opposed healthy pubis bone. The pubis member further includes a worm or other clamping method drive that is configured to tighten the clamping portion against the opposed healthy pubis bone thereby providing stability to the prosthetic hip bone and avoiding the use of bone screws in the opposed healthy pubis bone.

A61F 2/30

US Classification:

623 202, 623 1811, 623 2015

Abstract:

A patellar implant includes a posterior portion and an anterior portion. The posterior portion may define an articulating surface and a first retaining feature. The anterior portion may define a tissue engaging portion and a second retaining feature adapted to advance into a mechanical interlock with the first retaining feature in an assembled position. The mechanical interlock between the first and second retaining features may cooperate to resist separation of the posterior and anterior portions in the assembled position.

US Classification:

623 32, 623 2317, 606 62, 606282

Abstract:

An intramedullary fixation device and associated method. The intramedullary fixation device includes a first intramedullary component having a first bone-attachment end and a first elongated member, a second intramedullary component having a second bone-attachment end and a second elongated member, and a compliant member coupling the first and second intramedullary components for applying bone-compressing stress. The second intramedullary component defines a sleeve such that the first elongated member can pass therethrough.

Appl. No.:

12/038538

Inventors:

Brian M. May - Warsaw IN, US
Philip Faris - Indianapolis IN, US

Assignee:

Biomet Manufacturing Corp. - Warsaw IN

International Classification:

A61F 2/38

US Classification:

623 2017, 623 2034

Abstract:

A press-fit prosthesis for replacing a portion of a bone. The prosthesis can comprise a first side and a second side opposite the first side. The second side can be operable to engage the bone. The prosthesis can include at least one resorbable fixation member coupled to the second side such that the at least one resorbable fixation member does not extend through to the first side. The at least one resorbable fixation member can be coupled offset from a center of the second side. The at least one resorbable fixation member can substantially resist movement of the prosthesis relative to the bone. The at least one resorbable fixation member can resorb at a rate that enables bone in-growth to fixedly couple the prothesis to the bone.

International Classification:

A61F 2/32

US Classification:

623 2221

Abstract:

A prosthetic system for replacement of a portion of a hip bone including a plurality of acetabular components and a plurality of flange components. The prosthetic system also includes a plurality of pubis components. Each of the pubis components and each of the flange components are operable to connect to each of the acetabular components. Each of the pubis components define a clamping portion that is configured to attach to an opposed healthy pubis bone. An angle between the flange component and the pubis component varies among the acetabular components.

Biomet Manufacturing Corp. - Warsaw IN

International Classification:

A61F 2/08

US Classification:

623 1314, 623 2211

Abstract:

A system and method for attaching soft tissue to a prosthetic implant can include a prosthetic component that defines a soft tissue attachment region having an attachment surface thereon. A first construct can be formed of porous metal and be removably coupled to the attachment surface. A second construct can be positioned outboard of the soft tissue. A fastener can be engaged to the second construct capturing the soft tissue against the first construct. The fastener can be coupled on a distal end to the first prosthetic component.

Abstract:

A modular knee prosthesis can include a femoral component having a superiorly extending portion, a first femoral bearing surface and a second femoral bearing surface. The superiorly extending portion can define a first tapered augment receiving surface. A tibial component can have an inferiorly extending portion and a tibial bearing surface. The inferiorly extending portion can define a second tapered augment receiving surface. A first augment can define a first receiving bore and a first stepped surface. A second augment can define a second receiving bore and a second stepped surface. The first and second augments are adapted to mate at the first and second stepped surfaces in a first position at the first tapered augment receiving surface of the femoral component and in a second position at the second tapered augment receiving surface of the tibial component.
