Abstract
A urological device comprises a urological valve for location in the bladder of a patient and a valve support stem for location in the urethra of a patient. The valve has a normally closed configuration to prevent flow from the bladder and an open configuration for fluid flow through the valve. The valve is automatically movable from the closed configuration to the open configuration in response to a pre-set hydrodynamic pressure applied for a pre-set time. In one case the valve has a plurality of valve leaflets with a region of co-aption between the valve leaflets. In the normally closed configuration the valve leaflets are engaged at the region of co-aption and in the open configuration the leaflets are separated at the co-aption region for fluid flow through the valve.
