Transcatheter prosthetic heart valve post-dilatation remodeling devices and methods
First Claim
1. A method of remodeling a prosthetic heart valve of a patient, the method comprising:
- percutaneously delivering a remodeling balloon in a deflated state to an implanted, fully expanded prosthetic heart valve, the balloon including a remodeling segment, the remodeling segment having a longitudinal length less than a longitudinal length of the implanted, fully expanded prosthetic heart valve;
arranging the remodeling segment within a region of the implanted, fully expanded prosthetic heart valve to be remodeled, the region to be remodeled having a longitudinal length less than the longitudinal length of the implanted, fully expanded prosthetic heart valve;
inflating the remodeling balloon such that the remodeling segment expands and contacts the implanted, fully expanded prosthetic heart valve in the region to be remodeled; and
expanding the region to be remodeled via continued inflation of the remodeling segment to alter a shape of the implanted, fully expanded prosthetic heart valve to a remodeled state;
wherein the step of expanding includes remodeling the implanted, fully expanded prosthetic heart valve primarily at the region to be remodeled as compared to other regions of the implanted, fully expanded heart valve.

Abstract
A system and method for restoring (e.g., replacing) a defective heart valve of a patient. A delivery system is manipulated to percutaneously deliver and implant a stented prosthetic heart valve to a native heart valve. A post-dilatation balloon is percutaneously delivered to the implantation site, and a compliant segment thereof is arranged within a region of the implanted prosthesis. The balloon is inflated such that the compliant segment expands and contacts the prosthesis, expanding a remodeling region of the prosthesis to a remodeled state. With these and related techniques, remodeling of an implanted, stented prosthetic heart valve to better match the native valve shape is possible, providing many benefits such as reducing the risk of paravalvular leaks.

20. A method of remodeling a prosthetic heart valve of a patient, the method comprising:
-
evaluating an arrangement of an implanted, fully expanded, self-expandable prosthetic heart valve; percutaneously delivering a remodeling balloon in a deflated state to the prosthetic heart valve, the balloon including a remodeling segment, the remodeling segment having a longitudinal length less than the longitudinal length of the implanted prosthetic heart valve; arranging the remodeling segment within a region of the prosthetic heart valve to be remodeled, the region to be remodeled having a longitudinal length less than the longitudinal length of the implanted prosthetic heart valve; inflating the remodeling balloon such that the remodeling segment expands and contacts the prosthetic heart valve in the region to be remodeled; and expanding the region to be remodeled via continued inflation of the remodeling segment to alter a shape of the prosthetic heart valve to a remodeled state to thereby reduce paravalvular leakage; wherein the step of expanding includes remodeling the implanted, fully expand prosthetic heart valve primarily at the region to be remodeled as compared to other regions of the implanted, fully expanded heart valve.
