Abstract
A heart valve stent having a section with a heart valve implant and several proximally disposed tissue anchors, also comprising a plurality of anchoring threats, each with a proximate end fastened to the stent or valve and a distal end attached to tissue within a heart chamber to provide tension between the heart chamber tissue and the stent.
Claims11
A heart valve stent, comprising:
- a self-expanding catheter-inserted stent body section with valve leaflets disposed therein and self-expanding atrial retaining braces for atrial anchoring located at a proximal end of said stent body section said atrial retaining braces comprising a retaining skirt of a plurality of radial tooth-like projections circumferentially disposed around the proximal end of the stent body section, said tooth-like projections having a serrated, arched or triangular shape and extending radially outward from the proximal end of said stent body section at an angle bent away from the stent body section, said projections covered with a sealing membrane;
- and at least one ventricular anchoring suture attached to a distal end of said stent body section.
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;
- self-expanding atrial retaining braces for atrial anchoring located at a proximal end of said stent body section, said atrial retaining braces comprising a retaining skirt of a plurality of radial tooth-like projections circumferentially disposed around the proximal end of the stent body section, said tooth-like projections having a serrated, arched or triangular shape and extending radially outward from the proximal end of said stent body section at an angle bent away from the stent body section, said projections covered with a sealing membrane;
- 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 heart valve stent further comprising a circular, oval-shaped or u-shaped annulus and either a mitral valve or a tricuspid valve;
- and, at least one ventricular anchoring suture;
- and wherein the ventricular anchoring suture is adjustable.
