A delivery catheter for a stent. The delivery catheter may have a distal end and a proximal end. The distal end includes a stent attachment region adapted to receive a stent. The stent may be of the self-expanding type. The catheter further includes a handle at its proximal end and at least one sheath which may at least partially circumferentially cover the stent such as to retain it in a collapsed configuration. The sheath is coupled at its proximal end to an actuator located on the handle portion. The catheter further includes at least one radio-opaque indicator for indicating a rotational orientation of the delivery catheter and/or the stent when observed using medical imaging during implantation of the stent.

A hybrid prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be expanded post implant in order to receive and/or support an expandable prosthetic heart valve therein (a valve-in-valve procedure). The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander. An inflow stent frame is expandable for anchoring the valve in place, and may have an outflow end that is collapsible for delivery and expandable post-implant to facilitate a valve-in-valve procedure.

An implant and method for manufacturing an implant comprising an implant body defining a longitudinal axis and a structurally encoded pin contained within the implant body and aligned substantially along the longitudinal axis, the structurally encoded pin having a shape or surface characteristics discernable by an imaging modality such as x-ray, fluoroscopy, computed tomography, electromagnetic radiation, ultrasound, visible light, UV light, magnetic resonance imaging, positron emission tomography and neutron imaging, from outside the implant body, the shape or surface characteristics representing structurally encoded data. The structurally encoded pin is encoded via an electric discharge machining process.

A spinal implant device identifiable after implantation comprises an outer cage member and an implant body. The implant body is disposed between a first vertebra end and a second vertebra end of the outer cage and defines a plurality of planes. Each of the planes comprises separately readable indicia such that the indicia are discernible by at least one of x-ray, fluoroscopy, computed tomography, electromagnetic radiation, ultrasound, or magnetic resonance imaging.

A prosthesis may include a stem, a ball stud, an adaptor, and a head. The stem may include a longitudinal axis and a bore having a central axis that is angled relative to the longitudinal axis. The ball stud may include a cylindrical shaft and a ball end. The cylindrical shaft may be received in the bore of the stem. The adaptor may include a tapered outer surface and a ball socket rotatably receiving the ball end of the stud. The head may be rotatably supported by the adaptor and may include a semispherical articulating surface and a female taper rotatably receiving the tapered outer surface of the adaptor.

A kit for preparing an intervertebral disc space for receiving an implant (100) includes a plurality of trials (152) having different sizes. Each trial (152) includes a body (154) insertible into an intervertebral disc space, the body (154) having a leading end (162), a trailing end (164), a top surface (156) and a bottom surface (160), the top surface of the body having a first groove (176) formed therein. Each implant also includes a flange (166) secured to the trailing end (164) of the body (154), the flange (166) having a first channel (180) aligned with the first groove (176), wherein each of the different sized trials has a different flange thickness. The flange thickness controls advancement of a cutting tool such as a chisel (192) into the first groove at the top surface of the trial body, which controls the depth of the cut into vertebral bone.

In various embodiments, an intervertebral disc prosthesis is provided. The prosthesis may be provided with an insertion adapter, such as a head, holder, or other carrier of the prosthesis. The insertion adapter may be configured to retain the prosthesis and to engage an insertion tool body. In various embodiments, the prosthesis and the insertion holder are provided in a sterile pack, with the prosthesis components and the insertion holder sterilized and packaged in one or more types or layers of sterile packaging. In various other embodiments, the prosthesis and an insertion tool are provided in a sterile pack, with the prosthesis components and the insertion tool sterilized and packaged in one or more types or layers of sterile packaging.

Valve retainers and delivery systems with valve retainers are disclosed. In certain embodiments, a portion of the valve retainer can rotate about a central axis of the delivery system relative to a different portion of the valve retainer. In certain embodiments, a first portion of the valve retainer can include a plurality of first orientation markings. In certain embodiments, a second portion of the valve retainer can include a second orientation marking, which can be aligned with a first orientation marking on the first portion of the valve retainer.
