Embodiments of the present disclosure are directed to prosthetic heart valves and methods of use thereof. In one implementation, a prosthetic heart valve may include an annular spacer having a spacer opening therein and a disc-shaped wall configured to obstruct blood flow. The annular spacer may be configured for engaging with a native heart valve opening, such as the orifice of a mitral valve. The spacer opening may be sized to be smaller than the native heart valve opening. The prosthetic heart valve may also include a central valve section configured for disposal within the spacer opening. The central valve section may be separate from the annular spacer and may include one or more prosthetic valve leaflets.

There are provided a connectable catheter system, device and methods of use thereof. The connectable catheter system, comprising: an intermediary catheter and a reconnectable indwelling stent wherein the intermediary catheter and the indwelling stent are configured to connect, within a subject body to form a continuous fluid conduit between the intermediary catheter and the reconnectable indwelling stent and to further allow controlled release of substances and/or heating of internal target regions.

Particulate alloplastic bone replacement material and methods have a multitude of particles, wherein the particles have a core and at least six pins extending from the core, wherein the pins each have at least one connecting element, and wherein the pins are deformable elastically such that, upon multiple particles being pressed together, the connecting elements of different particles interlock with and/or snap into each other and the particles that are interlocked with and/or snapped into each other form an open-pored body of particles that are interlocked with and/or snapped into each other.

Prosthetic feet that provide improved rollover and performance are provided. A prosthetic foot can include a lower foot member extending from a heel end to a toe end, a second foot member disposed above the lower foot member, and an optional third foot member disposed above the second foot member. The second foot member is tapered such that its thickness decreases toward the proximal end. Optionally, the second foot member can taper toward its distal end as well as toward its proximal end from an intermediate location on the second foot member. The third foot member can be tapered such that its thickness decreases toward the distal end. There can be a gap between a distal end of the third foot member and the second foot member that closes during dorsiflexion of the prosthetic foot during use and provides dynamic stiffness control to the prosthetic foot.

Apparatuses, systems, and methods for prosthetic valves. Examples of prosthetic valves may be configured to anchor to an interior surface of a heart valve. Such prosthetic valves, in examples, may include a single frame that supports a plurality of prosthetic valve leaflets. In examples, multiple frames may be utilized to anchor to a heart valve and one or more of the frames may support a plurality of prosthetic valve leaflets.

A prosthetic valve includes an expandable valve frame and leaflets supported therein. A plurality of elongate anchor arms extends from an outlet end portion of the valve frame. Each elongate anchor arm includes anchoring protrusions, such as barbs, for engaging surrounding tissue. During delivery to the treatment site, the anchoring protrusions face inwardly. When released from the delivery catheter, the anchoring arms evert such that the anchoring protrusions reverse orientation and face outwardly. In this position, the protrusions can engage surrounding tissue and thereby secure the prosthetic valve within a native heart valve.

Devices, systems, and methods relate to implants, such as prosthetic valves for replacing native heart valves. Delivery systems for delivering the implants to an implantation site are also disclosed herein. A prosthetic valve may include a valve body supporting a plurality of prosthetic valve leaflets and one or more adjustable anchors coupled to the valve body for anchoring the prosthetic valve to leaflets of a native heart valve, wherein at least one of the adjustable anchors is axially slidable relative to the valve body for conforming to the native anatomy of the native heart valve.

A biodegradable double-J stent and a method of manufacturing a biodegradable double-J stent are provided. The stent comprises a main tube, a first retaining tube, and a second retaining tube, each fabricated from a biodegradable material. The first and second retaining tubes are curl-shaped and are connected to two ends of the main tube, respectively. The method of manufacturing a biodegradable double-J stent comprises the steps of: (a) providing a tube made of a biodegradable material; and (b) bending two ends of the tube to render the two ends curl-shaped and keeping a middle segment between the two ends straight. The two curl-shaped ends define a first retaining tube and a second retaining tube, respectively, and the middle segment defines a main tube. The biodegradable double-J stent precludes a ureteral obstruction which might otherwise occur with conventional double-J stents not removed in a timely manner.

Provided is a stent pusher assembly for positioning a ureteral stent, the stent pusher assembly having an inner and outer stent pusher. The stent pusher assembly positions the ureteral stent in a patient's kidney and bladder without a bladder fixing portion of the stent entering a ureteral passage-way, thereby minimizing irritation to the patient.

Funnel-trap type delivery and/or retrieval devices for Inferior Vena Cava (IVC) filters or other medical implants are described in which the devices comprise two layers of braid with an axially support member. The support member may be interposed between braid layers or set inside the braid layers but interposed between heatset features. Delivery and/or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated herein.
