PROSTHETIC HEART VALVE WITH INCREASED LUMEN

摘要

A heart valve prosthesis (10) having a valve housing (12) providing a lumen (17) therethrough. The valve housing (12) has a first annulus on one end and a second annulus on the other end spaced apart from the first annulus. A suture cuff (50) is used for attaching the valve housing to heart tissue of a patient. The cuff (50) is attached between the first annulus and the second annulus. The cuff (50) is positioned such that prosthesis (10) is attached in a supra-annular position relative to a tissue annulus of the heart. The design allows for an increased valve lumen.
