Prosthetic vascular conduit and assembly method

摘要

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.

主权项

1. A method of assembling a prosthetic valved conduit, comprising:
providing a kit including: a prosthetic heart valve having an annular portion; a prosthetic vascular conduit having a terminal collar member to receive the annular portion of the prosthetic heart valve, the terminal collar member including a cuff that is radially contractible to engage the annular portion of the prosthetic heart valve to couple the prosthetic heart valve to the prosthetic vascular 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 to house the prosthetic heart valve, wherein the prosthetic vascular conduit is fitted on the holder device so that at least a portion of the conduit adjacent to the cuff wraps around the receiving portion of the hub; and a sleeve member fitted onto the prosthetic vascular conduit at a position corresponding to the receiving portion of the hub, wherein the cuff is wrapped at least partially over the sleeve member; advancing the prosthetic heart valve into the receiving portion of the hub until the annular portion of the prosthetic heart valve contacts the receiving portion; sliding the sleeve member away from the hub to cause the cuff of the prosthetic vascular conduit to wrap around the annular portion of the prosthetic heart valve; and securing the cuff of the prosthetic vascular conduit around the annular portion of the prosthetic heart valve by radially contracting the cuff.
