Urological device

摘要

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.

主权项

1. A urological device comprising:
a valve support stem for location in a urethra of a user, the valve support stem extending between a proximal end and a distal end; a bladder retainer connected to the proximal end of the valve support stem, the bladder retainer including a concave-shaped exterior surface adapted for placement in a bladder of the user; and a urological valve disposed in the bladder retainer at a location proximal from the proximal end of the valve support stem, the urological valve including a leaflet extending from an interior surface of the bladder retainer away from the valve support stem; wherein the leaflet of the urological valve has a closed configuration adapted to prevent a flow of urine through the valve support stem and the leaflet of the urological valve is adapted to respond to a pressure and move to an open configuration adapted to allow a flow of urine through the valve support stem; wherein the leaflet extends from the interior surface of the bladder retainer to a location that defines a top proximal end of the device.
