摘要: A device for releasing a therapeutic agent in the body space in the form of a prosthetic joint implant having a first portion such as a stemmed portion for contacting bone tissue in an intramedullary canal of a long bone. The implant has a second portion which extends into the body space such as a joint space. The joint component contains a reservoir filled with a bioabsorbable/resorbable polymer which includes a therapeutic agent. The reservoir is open or in contact with the joint space as the body fluid diffuses in and out of the polymeric device it carries the drug into the joint space.

摘要: A femoral component for a hip prosthesis has a proximal end for disposition at a superior position in a femur and a distal end opposite the proximal end. The femoral component has opposite medial and lateral sides and opposite anterior and posterior faces extending between the medial and lateral sides. At least a proximal part of the femoral component has a first superior-to-inferior taper so that a medial to lateral dimension decreases gradually from the proximal end toward the distal end, a second superior-to-inferior taper so that an anterior to posterior dimension of the femoral component decreases gradually from the proximal end toward the distal end and a lateral-to-medial taper so that an anterior to posterior dimension of the femoral component decreases gradually from the lateral side toward the medial side.
