An aortic arch graft includes a generally cylindrical member formed from a plurality of struts having a proximal end and a distal end and a longitudinally extending lumen. The proximal end is configured for deployment within the ascending aorta and the distal end configured for deployment in the descending thoracic aorta. The aortic arch graft includes a graft material having an opening disposed between the proximal end and distal end with a plurality of radiopaque markers disposed around a periphery of the opening. The opening within the graft material allows blood flow transverse to the longitudinal lumen of the generally cylindrical member.

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.

Some target anatomies within the ear, nose and/or throat of a patient may be difficult to access and treat. To provide a means of treating such target anatomies over time, drug delivery devices that are sized to be positioned within a naturally occurring or man-made anatomical cavity or passageway are preloaded with active agent(s). The drug delivery devices are affixed directly to, or in the vicinity of, a target anatomy. Once affixed, the drug delivery devices are configured to deliver active agent(s) at desired dosage(s) to the target anatomy through controlled elution of the active agent(s) as various structural features of the drug delivery devices are bio-eliminated.

A prosthetic mitral valve has an interior stent and an exterior mesh surrounding the interior stent. The prosthetic mitral valve is released from a capsule and self-expands within a native mitral valve. The exterior wire mesh has a first portion with an enlarged diameter sized for placement above a mitral annulus and a second portion with a reduced diameter for contacting the mitral annulus. Capturing elements are provided on the interior stent. The capturing elements extend in a ventricular direction beyond the exterior wire mesh and then turn in an atrial direction for trapping native mitral leaflets against an outer surface of the wire mesh. A plurality of valve leaflets is provided within the interior stent for replacing the function of the native mitral valve.

A tray assembly may include a bottom portion having a bottom wall and first, second, third, and fourth side walls each extending upward from the bottom wall, and a top portion having a top wall and first, second, third, and fourth sides. The top portion is configured to releasably engage the bottom portion. The bottom portion includes at least one notch formed in an upper edge of the first side wall, the at least one notch being configured to receive an elongate shaft of an implant delivery device. A kit for preparing a replacement heart valve implant for delivery may include the tray assembly, at least one rinsing bowl, and a loading tools kit for attaching the replacement heart valve implant to the implant delivery device.

Endovascular systems for deployment at branched arteries include a main tubular graft body deployable within a main artery including a proximal end and an opposed distal end. The proximal and distal ends have a tubular graft wall therein between. A plurality of inflatable channels are disposed along the main tubular graft body, and at least one stent segment is disposed along the tubular graft wall of the main tubular graft body. The plurality of inflatable channels are configured to be inflatable with an inflation medium. The at least one stent segment is disposed between two or more adjacent inflatable channels of the plurality of inflatable channels.

A prosthetic heart valve includes a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end, the stent including a plurality of struts. A cuff may be coupled to the stent so that a flat, bottom edge of the cuff lies adjacent the proximal end of the stent. A pattern of stitches may be circumferentially disposed around the flat bottom edge of the cuff, the pattern of stitches alternating between stitches sewn to the cuff only and stitches sewn to both the cuff and the stent.

A multi-part intraocular lens (IOL) with an interchangeable optic seated on a base and secured by a locking mechanism. The optic comprises an anterior surface with a diameter greater than a diameter of a ring of the base. The posterior side of the optic has a posterior surface, a transition region for contact with the base, and sidewalls and tabs radially outward of the transition region. The sidewalls and tabs overlap at least a portion of the ring to reduce or even prevent decentration and tilt of the optic. Each tab has a lateral extension for coupling to the base.

Apparatus and methods are described herein for various embodiments of a prosthetic heart valve, delivery apparatus and delivery methods for delivering a prosthetic heart valve to a heart of a patient via a transapical or transvascular delivery approach. In some embodiments, a prosthetic heart valve includes an outer frame coupled to an inner frame and the outer frame is movable between a first configuration relative to the inner frame and a second inverted configuration relative to the inner frame. The valve can be delivered to a heart using an apparatus that includes a delivery sheath that defines a lumen that can receive the prosthetic heart valve therein when the outer frame is in the inverted configuration. Actuation wires are releasably coupled to the outer frame and can be used to help revert the outer frame after the valve is deployed outside of the delivery sheath and within the heart.

A delivery system for delivering a heart valve prosthesis includes a heart valve prosthesis and a delivery catheter. The heart valve prosthesis includes an anchoring member and an inner valve support, and further includes a radially collapsed configuration and a radially expanded configuration. The delivery catheter includes a handle, an outer shaft, an intermediate shaft, an inner shaft, and a distal tip component. The delivery catheter further includes a delivery configuration. In the delivery configuration, the outer shaft of the delivery catheter is configured to retain a first portion of the anchoring member, the intermediate shaft is configured to retain a first portion of the inner valve support, and the distal tip component is configured to retain a second end of the anchoring member and a second end of the inner valve support each in a radially compressed state.
