摘要： A catheter assembly includes a catheter body having a catheter lumen. A manifold assembly is coupled with a proximal catheter portion. A manifold lumen extends through the manifold assembly, and the manifold lumen includes an assembly cavity extending around the proximal catheter portion. A fluid jet loop is coupled with a high pressure tube at a distal catheter portion. The catheter assembly further includes a composite guide having first and second guide portions. The first guide portion includes a proximal guide insert near the proximal catheter portion, the proximal guide insert is positioned within the assembly cavity, and includes a guide insert surface flush with a catheter body interior wall. The second guide portion includes a distal guide near the distal catheter portion including a tapered loop guide surface and an intermediate guide surface of the catheter lumen flushly engaged with a leading edge of the tapered loop guide surface.

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.
