Pre-assembled bioprosthetic valve and sealed conduit
First Claim
1. A valved conduit, comprising:
- a bioprosthetic valve including bioprosthetic tissue, the valve having been treated such that the tissue may be stored dry for extended periods without degradation of functionality of the valve; and
a conduit sealed with a bioresorbable medium to which the bioprosthetic valve is coupled so as to provide the valved conduit, wherein the conduit is secured to the bioprosthetic valve using a snap-fit connection.

Abstract
A valved conduit including a bioprosthetic valve, such as a heart valve, and a tubular conduit sealed with a bioresorbable material. The bioprosthetic heart valve includes prosthetic tissue that has been treated such that the tissue may be stored dry for extended periods without degradation of functionality of the valve. The bioprosthetic heart valve may have separate bovine pericardial leaflets or a whole porcine valve. The sealed conduit includes a tubular matrix impregnated with a bioresorbable medium such as gelatin or collagen. The valved conduit is stored dry in packaging in which a desiccant pouch is supplied having a capacity for absorbing moisture within the packaging limited to avoid drying the bioprosthetic tissue out beyond a point where its ability to function in the bioprosthetic heart valve is compromised. The heart valve may be sewn within the sealed conduit or coupled thereto with a snap-fit connection.
