Methods, devices and systems for anchoring and/or sealing a heart valve prosthesis and, in particular, a mitral valve prosthesis (202). Inflatable elements (204, 206) are used to seal and anchor the mitral valve prosthesis (202) and/or other elements associated with repairing a native mitral valve.

A prosthetic heart valve includes a collapsible and expandable frame having a main body, an atrial portion, and at least one ventricular anchor. The atrial portion extends radially outwardly relative to the main body and the ventricular anchor extends from a ventricular end of the main body. The main body and the atrial portion are preferably separate metal components that are coupled together via sutures or a fabric member. The prosthetic heart valve also includes a valve structure that is supported in the main body of the frame. The valve structure has a plurality of leaflets for regulating the flow of blood in one direction.

An orthotopic artificial bladder endoprosthesis includes a casing made of a PGA fiber fabric; the casing having two first connectors for the connection with the ureters of a patient and a second connector for the connection with the urethra of a patient; a support element being inserted in the casing; the support element being switchable between an extended configuration, in which it supports and maintains in position the casing, and a retracted configuration.

The present invention relates to a stent-graft system comprising a first hollow cylindrical stent-graft body and at least one second hollow cylindrical stent-graft body. The first and the second stent-graft bodies are two structurally separate stent-graft bodies, and each comprise a first end, a second end, and a longitudinal axis. The first and the second stent-graft bodies further each comprise a stent-graft portion and a stent portion. The stent portion of the first stent-graft body and the stent portion of the second stent-graft body are designed in such a way that they can be at least partially inserted into one another in order to form one shared stent portion which is free from prosthesis material.

A vascular stent, which includes: a stent body including a plurality of ring-shaped units arranged at intervals and a connecting portion connecting all the ring-shaped units into a tubular structure, wherein the tubular structure has a first covered segment and a second covered segment that are provided with membrane, and an exposed segment configured for engaging the first covered segment and the second covered segment. The vascular stent is reliable in installation, which is beneficial to reduce pre-operation and post-operation adjustment work. The stent system can realize the reliable installation of the vascular stent, which is beneficial to improve the quality of the operation and reduce the operation time.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for placement in vessels, appendages, and openings in a body including a frame having a proximal end, a distal end, and a longitudinal axis. In certain instances, the frame includes a waist portion angled relative to the longitudinal axis and one or more anchors arranged along the waist portion.

Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve may be radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The prosthetic valve may comprise an annular frame, a leaflet structure positioned within the frame and a plurality of outer skirts positioned around an outer surface of the frame, each outer skirt comprising an inflow edge secured to the frame and an outflow edge secured at intervals to the frame. The plurality of outer skirts may include a first outer skirt and a second outer skirt, wherein in the expanded configuration the first and second outer skirts include openings unsecured to the frame between the intervals. The inflow edge of the first annular outer skirt may be secured to the frame with sutures including radiopaque material. The first annular outer skirt may include radiopaque dye.

An implantable medical device includes an electronic control system and an actuator. The actuator changes shape in response to a command or action of the electronic control system to treat an ailment of a person.

A prosthesis secures a replacement valve in a heart. The prosthesis includes a radially expandable inflow section and outflow section, and migration blocker rods. The inflow section has a tapered shape and is implanted within an atrium of a heart adjacent a native valve annulus. The outflow section couples to the inflow section, and is configured to be implanted through the native valve annulus and at least partially within a ventricle of the heart. The migration blocker rods extend circumferentially around at least a portion of the outflow section and hold native leaflets of the heart valve. In a contracted configuration, the prosthesis may be implanted through a catheter into the heart. In an expanded configuration, the tapered shape of the inflow section in the atrium cooperates with the migration blockers in the ventricle to hold the prosthesis against the native valve annulus.

A polymer is composed of a linear chain acrylate and a multi-functional acrylate cross-linker. The polymerized composition exhibits a transition at a temperature between about 34° C. and about 50° C. The polymerized composition exhibits shape memory effects. In one embodiment, the linear chain is tert-butyl acrylate and the crosslinker is polyethylene glycol dimethacrylate. The resultant shape memory polymers may be used in medical devices to provide devices with different shapes for pre and post implantation.
