| 摘要 |
A urological device comprises a urological valve (1) having a plurality of valve leaflets (3, 4, 5) 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. |
