This invention relates to bioprosthetic heart valve stems that are fashioned of bioresorbable materials. Such stents may be configured as sheaths or frames contoured to the shape of a valvular graft. The stems are eventually resorbed by the patient, leaving a functional "stentless" valve with improved hemodynamic characteristics compared to stented valve implants.
La présente invention concerne des moulages de valvule cardiaque bioprothétiques confectionnés en matériaux biorésorbables. Ces moulages peuvent se présenter sous forme de gaines ou de cadres épousant la forme d'un greffon valvulaire. Ils sont finalement résorbés par le patient, laissant une valvule fonctionnelle "sans moulage" à caractéristiques hémodynamiques améliorées par rapport aux implants de valvules à moulage.
