Prosthetic heart valve devices and associated methods for percutaneous heart valve replacement are disclosed herein. A transcatheter valve prosthesis configured in accordance herewith includes a frame having a valve support and one or more support arms coupled thereto. The one or more support arms are configured to extend from the second end of the valve support toward the first end when the valve prosthesis is in an expanded configuration. When deployed in the expanded configuration, the one or more support arms have a curvilinear shape, such as a substantially S-shape, that at least partially engages tissue at the native heart valve.

A mounting bracket for a prosthetic foot configured to attach to a residual limb, comprising an upper member, a lower member and compression torsion joint. The upper member comprises an upper flange, a mating post, and mounting portion configured to attach to the residual limb. The lower member comprises a mating portion, a lower flange, and a mounting portion configured to attach to the prosthetic foot. The compression torsion joint couples the upper member to the lower member and is configured to limit the vertical movement and torsional movement of the upper member with respect to the lower member.

The disclosure provides an implant including first and second interconnected elongated articulating portions with vertebral contacting outer surfaces. The first and second interconnected elongated articulating portions have a first configuration for insertion into a disc space and a second configuration upon deployment in the disc space. In a first configuration the axes of the first and second interconnected elongated articulating portions are substantially axially aligned with each other and in a second configuration the axes of the portions are axially unaligned with each other. The first and second interconnected elongated articulating portions are configured to be deployed in situ from the first configuration to the second configuration by both pivoting. The implant is expandable in the height direction between the vertebral contacting outer surfaces while the implant is inside the disc space by sliding a portion of at least one of the first and second elongated articulating portions.

A stent graft device having radiopaque markers for rotational orientation. The stent graft device may include an expandable stent frame and attached graft member. Two radiopaque markers, one the mirror image of the other, positioned on opposite sides of the stent graft at the same axial position along the longitudinal axis of the stent graft device, may be used to provide fine granularity rotational orientation of the stent graft. The two radiopaque markers may be attached to a same stent element and be in the form of checkmarks or some other linear asymmetric design that allow a user to view rotational orientation of the stent graft device by the amount of alignment and overlap of the two radiopaque markers when viewed via an imaging device such as an x-ray.

An intervertebral implant has a hollow space formed within the implant and accessible through an elongate opening extending through a recessed portion of the side wall, and the hollow space is shaped to receive an engagement portion of a drive shaft of an insertion tool; and the intervertebral implant includes at least two guiding surfaces facing each other and being configured for sliding engagement by a portion of a sleeve of the insertion tool movably holding the drive shaft.

A system for spinal surgery includes a prosthesis comprising a plurality of bone anchors which engage an intervertebral construct for fusion or motion preservation. The fusion construct comprises a spacer optionally encircled by a jacket. The motion preservation construct may comprise an articulating disc assembly or an elastomeric disc assembly. Any of the constructs may occupy the intervertebral disc space between adjacent vertebrae after removal of an intervertebral disc. The anchors slidingly engage the construct to securely fix the prosthesis to the vertebrae. The anchors and jacket of the fusion construct provide a continuous load path across opposite sides of the prosthesis so as to resist antagonistic motions of the spine.

An implant device is provided that is configured for implantation at multiple locations between adjacent vertebrae. The implant device comprises an implant body, a first portion of the implant body, and a second portion of the implant body adjustably interconnected with the first portion. The implant body has a compact orientation and an extended orientation to allow the implant body to be shifted from one orientation to the other orientation for being positioned in any one of areas between the spinous processes of the adjacent vertebrae, between laminar regions of the adjacent vertebrae, spanning an opening in the annulus between the adjacent vertebrae, and in the intervertebral space between the adjacent vertebrae.

An intervertebral fusion cage that is adapted to contain an inserter within its inner volume during insertion of the cage.

Implantable valve for treating venous insufficiency having a self-expanding frame encased in polymer having a distal section for blood in-flow, a bulbous center section and a proximal section for blood out-flow. Polymeric leaflets have proximal ends forming an S-shaped valve outlet, or a valve outlet which spirals toward the proximal section. The valve opens and closes in response to venous blood flow and has distal portions which are integral with the inner polymer surface of the distal end of said bulbous section. The leaflets define a predominantly biomimetic sinus region with the bulbous section. Opening of the valve induces flushing of blood from the sinus region for smooth non-traumatic blood flow through said valve.
