First Claim
Patent Images
1. A heart valve stent, shaped as a truncated cone, comprising:
- a stent body section with a heart valve implant;
a plurality of tissue anchors attached to a proximal end of the stent body section in a radial pattern; and
a plurality of anchoring threads, each such thread having a proximal end attached to the stent and a distal end anchored to the opposite wall of the heart chamber via a tissue anchor.

12. A heart valve stent, shaped as a truncated cone, comprising:
- a foldable, self-expanding stent body section with a heart valve implant, wherein the stent body section is comprised of a cross-hatching of metal wire made from a shape memory alloy, including but not limited to the group of diamond-shaped hatching, loop-shaped hatching, or a similar pattern;
a plurality of serrated, arched or triangular atrial tissue anchors attached to the proximal end of the stent body section in a radial pattern;
said heart valve implant integrated within the lumen of the stent body section at or near the proximal end of the stent body section;
said valve implant further comprising one of the group of a circular, oval-shaped or u-shaped annulus and either a mitral valve or a tricuspid valve;
a sealing membrane between the heart valve implant and the stent;
a plurality of anchoring threads, each such thread having a proximal end attached to the stent and a distal end anchored to the tissue within the heart chamber via a tissue anchor; and
at least one suture-length regulatory element for adjusting the length and tension of at least one of the plurality of anchoring threads.
- a foldable, self-expanding stent body section with a heart valve implant, wherein the stent body section is comprised of a cross-hatching of metal wire made from a shape memory alloy, including but not limited to the group of diamond-shaped hatching, loop-shaped hatching, or a similar pattern;
