Urological device
First Claim
1. A urological device comprisinga urological valve,a support for the valve, the support being generally tubular and adapted for mounting in a urinary tract,a bladder retainer for locating the device in a bladder and a urethral retainer to prevent migration of the device,the valve including a plurality of valve leaflets,the valve having internally located, stiffening reinforcement members the stiffening reinforcement members defining a fulcrum or hinge region about which the valve leaflets are movable from a normally closed configuration to an open configuration, the stiffening reinforcement members extending vertically,the valve having a region of co-aption between the valve leaflets, the valve having the normally closed configuration in which the valve leaflets are engaged at the region of co-aption and the open configuration in which the leaflets are separated at the co-aption region for fluid flow through the valve, the valve leaflets being configured to evert automatically on movement between the closed configuration and the open configuration in response to applied urological pressure.

Abstract
A urological device comprises a urological valve having a plurality of valve leaflets with a region of co-aption between the valve leaflets. The valve has a normally closed configuration in which the valve leaflets are engaged at the region of co-aption and an open configuration in which the leaflets are separated at the co-aption region for fluid flow through the valve. The valve is automatically movable from the closed configuration to the open configuration in response to applied urological pressure.
