An in-situ fenestration device. The device includes a sheath, a sonic catheter extending with the sheath and having a cutting tool at a distal section thereof, and a balloon catheter extending within the sonic catheter. The cutting tool of the sonic catheter is configured to cut a fenestration in a graft material at a fenestration site of a stent graft upon being energized with ultrasonic energy at a cutting frequency.

In-situ fenestration devices with ultrasonic cutter

A prosthesis includes a frame and a skirt coupled to a surface of the frame. The skirt extends over at least one side opening of a plurality of side openings of the frame. The prosthesis also includes a skirt-reinforcement member that spans the at least one side opening from a first crown or strut edge defining the at least one side opening to a second crown or strut edge defining the at least one side opening. The skirt-reinforcement member has a first end, a second end, and a length therebetween. The first end of the skirt-reinforcement member is attached to the first crown or strut edge and the second end of the skirt-reinforcement member is attached to the second crown or strut edge. The skirt-reinforcement member is attached to the skirt along an unsupported portion of the skirt that spans the at least one side opening.

Skirt-reinforcement members for prosthetic valve devices

The devices and methods of this disclosure relate to a heart valve prosthesis that is configured to be implanted within a native heart valve having a smaller perimeter annuli with a generally elliptical shape.

Compact prosthetic heart valve device

A skirt-reinforcement member for supporting or reinforcing an unsupported portion of a skirt that spans across a side opening of a stent or frame of a valve prosthesis. The skirt-reinforcement member is configured to prevent billowing of the skirt material that spans across the side opening of the inner frame of the valve prosthesis, as such billowing may undesirably result in contact between the skirt and leaflets of the valve prosthesis after the valve prosthesis is deployed in situ.

Transcatheter aortic valve prostheses for improving the cardiac function of a patient suffering from coronary artery disease. Transcatheter aortic valve prostheses include a valve component and a frame. The valve component includes valve leaflets and a skirt. The frame includes access cells that improve access to a patient's coronary arteries if further intervention is required and/or includes a window or conduction protection cell that is oriented to align with a portion of conduction system of the heart in situ to reduce conduction disturbances of the anatomy. Suture patterns for attaching a commissure to a commissure post of the frame, and for attaching a tissue bumper to the commissure post, are also described.

Transcatheter heart valve prostheses

A 'dry' packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.

Packaging for dry tissue prosthetic heart valve

Described herein is a prosthetic valve device having an optimized valve component for durability and functionality of the collapsible leaflets. Specially designed commissures contribute to the optimization along with identified parameters. In other embodiments, the invention is a frame formed from a unique cutting pattern.
