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 is formed of a plurality of struts. A cuff is coupled to the stent. The cuff has one or more features configured to reduce abrasion and/or perivalvular leakage.

Cuff configurations for prosthetic heart valve

A method of preparing a tissue swatch comprising one or more desired thicknesses for use in the manufacture of a bioprosthetic device, the method comprising sectioning a sheet of frozen tissue to produce a tissue swatch of the one or more desired thicknesses.

Method of preparing a tissue swatch for a bioprosthetic device

A prosthetic valve assembly for implantation in a patient's circulatory system includes a stent, a valve member coupled to the stent and defining a preferred landing zone relative to anatomical structures in the patient's circulatory system, and at least one marker positioned in a predetermined relationship relative to the landing zone of the valve member, the marker being visually distinguishable from the stent using an imaging technique. By observing the marker, the prosthetic valve assembly may be implanted in the patient so that certain ones of the anatomical structures lie within the landing zone.

Method of placing a prosthetic valve assembly in a patient's circulatory system

A structure for sealing a gap between a medical device and adjacent body tissue includes a ring-shaped body formed at least in part of a material that expands from a compressed condition to an expanded condition when heated to a transition temperature and that is adapted to conform to the body tissue in the expanded condition.

Thermally-activated biocompatible foam occlusion device for self-expanding heart valves

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. The heart valve further includes a collapsible and expandable valve assembly including a cuff and a plurality of leaflets, the cuff being coupled to selected ones of the plurality of struts and having microspheres disposed therein. The microspheres are capable of expanding upon contact with blood.

A method of preparing a tissue swatch comprising one or more desired thicknesses for use in the manufacture of a bioprosthetic device, said method comprising sectioning a sheet of frozen tissue to produce a tissue swatch of said one or more desired thicknesses.
