摘要:
A catheter includes a pressure actuated seal within a manifold. A catheter body is coupled with the manifold, and a manifold lumen and catheter lumen are configured to receive pressurized fluids. The pressure actuated seal includes a pressure actuated seal element having a seal element lumen. The seal element lumen is in communication with the manifold and catheter lumens. The pressure actuated seal element is deformable between an open configuration and a sealed configuration. In the sealed configuration, the pressurized fluid in the manifold presses on the pressure actuated seal element along a first seal face. The pressure actuated seal element compresses inwardly around the seal element lumen according to the pressure of the pressurized fluid. In the open configuration, the pressure actuated seal element relaxes in the absence of the pressurized fluid, and the seal element lumen is open and configured to allow passage of an instrument.
