Prosthetic mitral valve
First Claim
1. A prosthetic heart valve having an inflow end and an outflow end, comprising:
- a stent having a collapsed condition, an expanded condition, and a plurality of cells arranged in a plurality of circumferential rows;
a plurality of engaging arms each pivotably disposed in a corresponding one of the plurality of cells adjacent the outflow end, the engaging arms each having a first strut coupled to the one cell, a second strut coupled to the one cell, and a third curved strut coupling the first strut to the second strut and defining a free end of the engaging arm extending toward the inflow end of the prosthetic heart valve;
a flange formed of a braided mesh and having a body portion coupled to the stent and a flared portion adjacent the inflow end of the prosthetic heart valve, the flared portion terminating at an inflow end of the flange and the body portion terminating at an outflow end of the flange, the outflow end of the flange being positioned between the free end of the engaging arm and the one cell in the expanded condition of the stent; and

Abstract
A prosthetic heart valve having an inflow end and an outflow end includes a stent having a collapsed condition, an expanded condition, and a plurality of cells arranged in circumferential rows. The stent may include one or more securement features. One securement feature may be an anchor arm having a body portion and a free end extending from the body portion, the body portion being coupled to a perimeter of one of the plurality of cells, with the free end extending toward the inflow end in an expanded condition of the anchor arm. Another securement feature may include a flange formed of a braided mesh and having a body portion coupled to the stent and a flared portion adjacent the inflow end of the prosthetic heart valve. A valve assembly is disposed within the stent and has a plurality of leaflets.
