The present disclosure is directed to embodiments of an occlusive medical device including a frame and at least one closure coupled to the frame. The frame includes a distal annular flange having a radially outer surface and a radially inner surface, a proximal annular flange having a radially outer surface and a radially inner surface, and a waist portion extending between and connecting the distal annular flange to the proximal annular flange. The radially inner surface of the distal annular flange, the waist member, and the radially inner surface of the proximal annular flange define an unobstructed passageway through the frame. The at least one closure is configured to close the passageway to: (i) provide an occlusive effect, and (ii) enable subsequent access through the passageway.

Occluder with access passage and closure thereof

A medical device including a removable frame and biomaterial cover, methods of assembling and using the same, and a delivery system including the same are described herein. The medical device includes a frame having proximal and distal ends, the frame including a proximal disc at the proximal end, a distal disc at the distal end, and a connecting segment connecting the proximal and distal discs. Each of the proximal and distal discs includes a respective plurality of prongs, the plurality of prongs each extending from the connecting segment to a free end. The medical device further includes at least one biomaterial cover including an outer section and an inner section defining a cavity therebetween, wherein at least one of the proximal and distal discs of the frame is positioned in the cavity.

Biomaterial occluder delivery mechanism

A heart prosthesis system may include a prosthetic heart valve and a length of suture. The prosthetic heart valve may include a collapsible and expandable stent and a valve assembly mounted within the stent. The stent may have an aortic end, an annulus end, and a plurality of openings arranged circumferentially around the aortic end, the aortic end having a first diameter in an expanded condition. The length of suture may be threaded through the openings such that tension applied to the length of suture in a direction away from the stent may collapse the aortic end of the stent from the first diameter to a second diameter less than the first diameter.

Fully deployable and recapturable prosthetic heart valve

A medical device including a removable frame and biomaterial cover, methods of assembling and using the same, and a delivery system including the same are described herein. The medical device includes a frame having proximal and distal ends, the frame including a proximal disc at the proximal end, a distal disc at the distal end, and a connecting segment having a proximal end and a distal end connecting the proximal and distal discs. Each of the proximal and distal discs includes a respective plurality of prongs and has a maximum cross-sectional dimension larger than the connecting segment. The medical device further includes at least one biomaterial cover including an outer section and an inner section defining a cavity therebetween, wherein at least one of the proximal and distal discs of the frame is positioned in the cavity.
