DUAL-FLANGE PROSTHETIC VALVE FRAME

摘要

Embodiments of prosthetic valve frames for implantation within a native mitral valve can include a main body portion, and first and second radially extending flanges coupled to the main body portion. The flanges can be coupled to the main body such that the flanges are spaced father apart from one another when the main body portion is in a crimped configuration than when the main body portion is in an expanded configuration. Associated delivery systems and methods of delivery are provided.

1. An implantable prosthetic valve comprising:
a radially collapsible and radially expandable annular main body defining a lumen therethrough; a first flange coupled to the main body and extending radially away from the main body, the first flange comprising a plurality of radially extending first protrusions; a second flange coupled to the main body and extending radially away from the main body, the second flange comprising a plurality of radially extending second protrusions; and a valve member supported within the lumen of the frame; wherein the first flange and the second flange are closer to one another when the main body is in a radially expanded configuration than when the main body is in a radially collapsed configuration; and wherein each of the first protrusions and each of the second protrusions comprise a first radial strut coupled to a first node of the main body and extending radially away from the main body, a second radial strut coupled to a second node of the main body and extending radially away from the main body, a first angled strut coupled at an angle to the first radial strut, and a second angled strut coupled at an angle to the second radial strut and coupled to the first angled strut.
