A prosthesis includes a tubular graft, a prosthetic valve component, an inflow stent, an outflow stent, and a plurality of body stents disposed between the inflow and outflow stents. Each stent is a sinusoidal patterned radially-expandable ring having a first set of crowns and a second set of crowns, with the first set of crowns disposed closer to an inflow end of the tubular graft than the second set of crowns. The prosthesis is configured to be resistant to backfolding and/or buckling during deployment thereof.

Prosthetic valve device resistant to backfolding and buckling

A delivery system for a prosthetic valve device includes a first shaft including an outflow capture device mounted on a distal end thereof, a second shaft slidingly disposed over the first shaft and including an inflow capture device mounted on a distal end thereof, and a retractable sheath slidingly disposed over the second shaft to hold the prosthetic valve device in a radially compressed configuration for delivery to a body lumen. The inflow capture device is configured for releasable engagement through openings in a plurality of first attachment members on the device. The outflow capture device is configured for releasable engagement through openings in a plurality of second attachment members on the device.

Delivery system for prosthetic valve device having controlled release of inflow and outflow ends

Methods and apparatus for holding and maneuvering a valve during preparation and attachment to patient, providing increased visibility of the prosthetic valve and the sewing ring to prevent suture entanglement. A handle attachment is spaced from the valve for improved visibility of the sewing ring and the outlet end of the valve during attachment. Commissure posts are bent inward at the tips while preventing crashing of the commissure posts into each other causing damage. A release force needed to remove the holder and unthread the holder sutures is reduced. The holder and related methods can provide a kink free holder suture path to reduce suture entanglement and prevent damage to the implanted valve during holder removal by reducing the release force needed to remove the holder sutures by up to 30%.

Valve delivery device

An annuloplasty ring including a sheath, an arcuate stiffening element, and a tensioning member. The stiffening element is disposed within the sheath and defines discrete, first and second ends separated by a lateral spacing. The tensioning member extends between the stiffening element ends. The tensioning member is characterized as being more flexible than the stiffening element and is configured to provide a taut state in which the tensioning member is substantially non-extensible and impedes expansion of the lateral spacing. With this configuration, the stiffening element serves to remodel the valve annulus to a desired shape, while the tensioning member exhibits sufficient flexibility to allow for natural movement of the valve annulus while limiting (in the taut state) the extent of annular dilatation (e.g., overt lateral separation of the first and second ends of the stiffening member) due to in vivo forces.

Annuloplasty ring and method

An ablation catheter including an inner tube having a length, a distal end and a longitudinal axis, a plurality of needles extending from the distal end of the inner tube and biased away from the longitudinal axis, an outer sheath slideably moveable relative to the inner tube to surround at least a portion of the length of the inner tube and its extending needles, and a radio frequency energy source electrically connected to the plurality of needles.

Paravalvular leak closure devices and methods

A valve holder for a prosthetic valve having a stent comprising a stent base and multiple commissure posts projecting from the stent base, the valve holder including a connector hub, a plurality of legs connected to the connector hub, each leg having an elongate portion and a commissure post engaging plate, a sliding member slideably connected to each leg of the plurality of legs and positioned between the connector hub and the commissure post engaging plates of the plurality of legs and slideably positionable at a first position relative to the connector hub with the commissure post engaging plates in an uncompressed configuration and a second position relative to the connector hub with the commissure post engaging plates in a compressed configuration, and a handle extending from the connector hub.

Heart valve holder for use in valve implantation procedures

The invention features a valve holder for a prosthetic valve having a stent with a stent base and multiple commissure posts projecting from the stent base. The valve holder includes (i) a central base portion, (ii) a plurality of legs radially extending from the central base portion, and (iii) a handle extending from the central base portion. At least one of the legs of the holder has a first prong portion separated from a second prong portion by a gap. The leg also has a of commissure post engaging member that is slideably engaged with the leg.

A valve holder assembly for delivering a prosthetic heart valve having a stent base an multiple extending commissure posts. The valve holder assembly includes a holder and a rotor that is rotatable relative to the holder.

Heart valve holder assembly for use in valve implantation procedures

A valve holder for a prosthetic valve having a stent with a stent base and multiple commissure posts projecting from the stent base, the valve holder including a central base portion, a plurality of legs radially extending from the central base portion, each leg comprising a first prong portion spaced from a second prong portion by a gap distance, a plurality of commissure post engaging members, wherein one commissure post engaging member is slideably engaged with each of the plurality of legs, and a handle extending from the central base portion.

A dosing device is described, in which a predetermined amount of a material such as a concentrated fluid can be dispensed from the device by finger pressure. In one embodiment, the device includes a shuttle that can move between first and second positions. In the second position, fluid can escape from a dosing chamber.
