Bioresorbable heart valve support
First Claim
1. A bioprosthetic heart valve comprising a valvular tissue graft secured to a biocompatible, is contoured to said valvular tissue graft, said bioprosthetic heart valve being appropriate for joining with valve-receiving cardiac tissue, wherein said stent is operably resorbed following substantially complete healing of said heart valve with said valve-receiving cardiac tissue.

Abstract
This invention relates to bioprosthetic heart valve stents that are fashioned of bioresorbable materials. Such stents may be configured as sheaths or frames contoured to the shape of a valvular graft. The stents are eventually resorbed by the patient, leaving a functional "stentless" valve with improved hemodynamic characteristics compared to stented valve implants.
