Prosthetic vascular conduit and assembly method
First Claim
1. A kit for assembling a prosthetic vascular conduit, the kit comprising:
- a prosthetic vascular conduit configured to be coupled to a prosthetic valve having an annular portion, the prosthetic vascular conduit including a terminal collar member adapted to receive the annular portion of the valve, the terminal collar member including a portion that is radially contractible to engage the annular portion of the valve to couple the valve to the conduit;
a holder device including a shaft and a hub located at an end of a proximal portion of the shaft, the hub including a receiving portion including an inner portion to house the prosthetic valve and an outer portion, wherein the prosthetic vascular conduit is fitted on the holder device so that at least a portion of the conduit adjacent to the terminal collar member surrounds the receiving portion of the hub and contacts the outer portion of the receiving portion; and
a sleeve member fitted onto and surrounding the conduit at a position corresponding to the receiving portion of the hub, wherein an inner surface of the sleeve member contacts the conduit and the terminal collar member is wrapped at least partially over and around the sleeve member such that the terminal collar member contacts an outer surface of the sleeve member;
wherein the sleeve member is removable from the hub so as to cause the terminal collar member to lose contact with the inner and outer surfaces of the sleeve member and be wrapped around the annular portion of the prosthetic valve when the prosthetic valve is housed within the inner portion of the receiving portion of the hub.

Abstract
A kit for implanting a prosthetic vascular conduit includes a prosthetic vascular conduit for coupling to a prosthetic valve having an annular portion. The conduit includes a terminal collar member for receiving the valve. The kit further includes a holder including a shaft and a hub including a receiving portion configured for housing a prosthetic valve. The conduit is fitted on the holder so that at least a portion of the conduit wraps over the receiving portion of the hub. A sleeve member fitted onto the conduit in a position corresponding to the receiving portion of the hub, and a portion of the collar member is wrapped or folded over the sleeve member. The sleeve member is slidable away from the hub to unwrap the collar member such that it is disposed around the annular portion of a prosthetic valve.
