Abstract
A valve prosthesis device is disclosed suitable for implantation in body ducts. The device comprises a support stent adapted to be initially crimped in a narrow configuration for catheterization through the body duct to a target location and adapted to be deployed to a deployed state in the target location, and a valve assembly comprising a flexible conduit having an inlet end and an outlet, made of pliant material providing collapsible slack portions of the conduit at the outlet. When flow is allowed to pass through the valve prosthesis device from the inlet to the outlet the valve assembly is kept in an open position, whereas a reverse flow is prevented. The device is configured so that retrograde flow will be altered from laminar flow and directed towards the leaflets to effect closing. The device can be deployed in a native heart valve position using a deployment catheter.
