Intervalvular implant for a mitral valve
First Claim
1. An intervalvular implant for a mitral valve, the implant comprising:
- a frame having an elongated base portion formed by first and second branches, each of the first and second branches having a curved or chevron shape, a first end portion, a median portion, and a second end portion, the median portions of the first and second branches spaced apart a width from each other, the first end portion of the first branch coupled to the first end portion of the second branch at a first connection area, the second end portion of the first branch coupled to the second end portion of the second branch at a second connection area, the first and second connection areas spaced apart a length from each other such that the length is three to eight times greater than the width between the median portions of the first and second branches,wherein the frame further comprises first and second anchoring portions connected to the first and second connection areas, respectively, the first and second anchoring portions configured to allow the implant to be anchored to an annulus of the mitral valve at two points of the annulus spaced apart and opposite each other,wherein the frame further comprises a longitudinal hoop extending from the first connection area to the second connection area; and
a flexible membrane configured to extend from the first branch to the second branch while passing around the longitudinal hoop so that the flexible membrane forms a first lateral portion and a second lateral portion, the flexible membrane coupled to the first and second branches so that the first and second lateral portions of the flexible membrane are transitionable between a convex shape and a concave shape,wherein the flexible membrane is affixed to the first and second branches.

Abstract
An intervalvular implant for a mitral valve having a frame and a membrane covering the frame is provided. The frame includes an elongated base portion formed by two curved or chevron branches connected to two connection areas of the implant for connecting to the annulus of the mitral valve. The frame further includes a longitudinal hoop extending in a plane substantially perpendicular to the plane in which the elongated base portion extends. The membrane is flexible and extends from one branch to the other branch while passing around the longitudinal hoop. The membrane may be connected to the branches without being stretched between the branches and the hoop so that the membrane forms lateral portions on each side of the implant that are able to transition between an outwardly convex, concave shape, and an outwardly concave, recessed shape.
