A woven prosthesis, such as a woven vascular graft, woven from warp and weft yarns. Velour warp yarns forming the prosthesis are selectively incorporated into a base layer of the prosthesis so as to provide a bulbous section without compromising the porosity of the prosthesis.

A transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent is mechanically or balloon expandable. The stent has an inflow portion and an outflow portion. The inflow portion includes a plurality of side openings defined by a plurality of crowns and a plurality of struts. The outflow portion has three circumferentially spaced apart commissure posts. The prosthetic valve is disposed within and secured to at least the outflow portion of the stent. The prosthetic valve is configured to block blood flow in one direction to regulate blood flow through a central lumen of the stent. The commissure posts are configured to flex or bend flex radially inwardly to reduce stresses observed during valve loading and thereby improve or increase tissue durability of the prosthetic valve.

A delivery apparatus for implanting a prosthetic heart valve includes one or more shafts and a handle coupled to the one or more shafts. The handle comprises one or more knobs, one or more adjustment mechanisms, and/or one or more control mechanisms. The knobs are configured for actuating the one or more adjustment mechanisms and/or the one or more control mechanisms. The one or more adjustment mechanisms are configured for moving the shafts relative to each other and/or relative to the handle. The one or more control mechanisms are configured for limiting the direction of movement and/or force applied to the one or more shafts.

A prosthetic heart valve including a frame, leaflet structure, and sealing member disposed around an outer surface of the frame is disclosed. As one example, the sealing member includes an inner layer and a plush outer layer comprising a plush outer surface. The inner layer is arranged against the outer surface of the frame and the outer layer is arranged against and attached to the inner layer. The inner layer is folded over at inflow and outflow ends, in an axial direction relative to a central longitudinal axis of the frame, to overlap respective ends of the outer layer and form tapered folds at opposite ends of the sealing member, each tapered fold including a narrower, first portion where the inner layer folds over and contacts itself and a wider, second portion where the inner layer overlaps an outer surface of an end portion of the outer layer.

A method, system, or apparatus for stent delivery. Delivering one or more stents with a delivery tool that can include a kinetic transfer of energy to deliver one or more stents. The stents can include a modifiable stent that can change its overall shape and/or dimensions based on pre-configured design parameters. A coil stent that can engage with a vessel that surrounds the modifiable stent forming a dual stent configuration. The coil stent can also include anchor points that allow it to engage with a second vessel securing the first vessel and the second vessel together to aid in the healing process.

A prosthetic heart valve comprises an annular frame comprising a plurality of interconnected struts, wherein the frame is radially compressible and expandable between a radially compressed state and a radially expanded state. A plurality of leaflets are situated within the frame, each leaflet comprising a main body, two opposing commissure tabs arranged on opposite sides of the main body and two opposing sub-commissure tabs arranged on opposite sides of the main body. Each commissure tab of a leaflet is paired with an adjacent commissure tab of an adjacent leaflet to form a commissure that is coupled to the frame. Each sub-commissure tab is paired with an adjacent sub-commissure tab of an adjacent leaflet and connected thereto, wherein each pair of sub-commissure tabs extends radially inwardly relative to the frame.

A transcatheter temporary valve prosthesis for blood vessel comprising an expandable support structure (5″), a valve (7), a filter (12) and a conveyor (6); said support structure (5″) forming a tubular shape when expanded, with a distal and a proximal end, said valve (7) being located at said distal end and said conveyor (6) extending within said support structure (5), from said proximal to said distal end and including a central passage that is adapted to act as an introducer for other devices.

The present invention relates to apparatus for treating urinary incontinence in a patient. In the apparatus, there is at least one adjustable lifting device adapted to lift the urethra or neck of the urine bladder, thereby affecting the patient’s incontinence. The lifting device is provided with first and second fixation devices and an interconnecting part extending uninterruptedly between the first and second fixation devices.

A catheter assembly for delivery of an expandable implant having at least one branch portal, which utilizes a secondary sleeve for releasably constraining a middle portion of the expandable implant after releasing a primary constraining sleeve used for constraining the expandable implant toward a delivery configuration for endoluminal delivery; and methods of using the same.

In some examples, a delivery device includes a handle that includes a control member, an elongate body, a plurality of arms extending from a distal portion of the elongate body to a distal collar configured to releasably couple to an annuloplasty device. The plurality of arms is operatively coupled to the control member and configured to position the annuloplasty device at a target site in a patient. The delivery device further comprises a plurality of anchors configured to secure the annuloplasty device to tissue at the target site, each respective anchor of the plurality of anchors deployable from a respective arm of the plurality of arms.
