Beating heart buttress and implantation method to prevent prolapse of a heart valve
First Claim
Patent Images
1. An apparatus for mitigating prolapse comprisinga support member having a flexible buttress, the support member configured to position the buttress spaced apart from at least one viable leaflet of a patient'"'"'s own heart valve, the buttress configured to coapt with the at least one viable leaflet to provide for unidirectional flow of blood in the space between the buttress and the at least one viable leaflet;
- an elongated tubular rod attached to and extending generally axially from the buttress and being dimensioned and configured with a length sufficient to extend from the annulus and anchor in tissue axially displaced from a valve annulus associated with the patient'"'"'s heart valve, the support member and the elongated tubular rod forming a unitary structure, the elongated tubular rod being configured to stabilize the support member and buttress at a desired axial position and angular orientation relative to the patient'"'"'s heart valve annulus; and
a lumen extending axially through the elongated tubular rod and through the support member.

Abstract
An apparatus and method for mitigating prolapsed are disclosed. The apparatus includes a contact member and an elongated rod that can be used to hold the contact member in position for coapting with a patient'"'"'s native leaflets. A similarly configured sizing apparatus can also be used to facilitate implantation.

10. An apparatus for mitigating prolapse comprising:
-
a support member covered with a substantially biocompatible layer of biological material, the support member having a flexible buttress, the support member configured to position the buttress spaced apart from at least one viable leaflet of a patient'"'"'s own heart valve, the buttress configured to coapt with the at least one viable leaflet to provide for unidirectional flow of blood in the space between the buttress and the at least one viable leaflet; an elongated tubular rod covered with a substantially biocompatible layer of biological material, the elongated tubular rod being attached to and extending generally axially from the buttress and being dimensioned and configured with a length sufficient to extend from the annulus and anchor in tissue axially displaced from a valve annulus associated with the patient'"'"'s heart valve, such that when implanted the elongated tubular rod can stabilize the support member and buttress at a desired axial position and angular orientation relative to the patient'"'"'s heart valve annulus; and a lumen extending axially through the elongated road and through the support member. - View Dependent Claims (12)
