摘要： Implant devices having an articular end for repair of articular cartilage defects are provided. The articular end has an oval perimeter, a convex upper face, and a concave lower face. The convex upper face has a first circular pitch radius and a first circular roll radius. At least a portion of the concave lower face has a spherical radius, the convex upper face blending into a rim, wherein at least a first and second portion of the rim extends at least a first distance along a vertical axis and a third and fourth portion of the rim tapers inward along the vertical axis, the rim blending into the concave lower face. The articular cartilage implant devices further include a stem extending from the concave lower face away from the convex upper face along the vertical axis. The stem has a plurality of oval shaped perimeters along the vertical axis.

摘要： An apparatus for proof testing mechanical heart valve prostheses. The apparatus also provides an in vitro test environment simulating in vivo loads, providing a function test. If the heart valve passes the pivot proof test, a function test is performed. The apparatus first directs a pressurized back flow against the tested valve, closing the valve and applying pressure against the leaflet occluders well beyond the maximum functional in vivo load. The heart valve is positioned so that the leaflets assume their "worst-case" position, that is, the heart valve is oriented so that all the necessary play or gap between the leaflet pivots and pivot recesses is subsumed at one location, thus representing the most severe condition that might be experienced with a heart valve in use. The heart valve is loaded by back pressure applied through a working fluid. Pressure transponders detect the pressure on each side of the heart valve, to determine if a valid test has been performed.
