Abstract: An anchor anchors a therapeutic device having an elongated body within a body lumen. The anchor includes a fixation member carried on the device which is adjustable from a first configuration that permits placement of the device in the body lumen to a second configuration that anchors the device within the body lumen. The anchor further includes a lock that locks the fixation member in the second configuration. The fixation member may be locked in any one of a plurality of intermediate points between the first configuration and a maximum second configuration.

Abstract: Each of an osteochondral plug graft and a kit comprises a trapezoid shaped construct configured for osteochondral implanting. An osteochondral regeneration method comprises forming a recipient socket in a chondral area of an articular joint in need of repair; harvesting a trapezoid shaped graft from another chondral area; and implanting the trapezoid shaped graft into the recipient socket.

Abstract: In one embodiment of the present invention a mobile bearing knee prosthesis may include an interface (e.g., a spherical radius interface) comprised of a concave superior surface on a tibial tray and a convex inferior surface on a tibial insert. In another embodiment of the present invention a mobile bearing knee prosthesis may include an interface (e.g., a spherical radius interface) comprised of a convex superior surface on a tibial tray and a concave inferior surface on a tibial insert. In another embodiment of the present invention a mobile bearing knee prosthesis may include a bi-concave interface (e.g., having a “wave” like surface geometry). This “wave” like surface geometry may be at the second bearing (i.e., at the interface between a tibial insert and a tibial tray in the mobile bearing knee as opposed to the interface between the tibial insert and a femoral component).
