Valved over-the-wire catheter |
摘要 |
A catheter with a distal end having a member formed from a hydrophilic composition is provided. The hydrophilic composition expands upon contact with an aqueous fluid to move the member from a quiescent state to an expanded state. The member may provide an open passageway in the quiescent state and be capable for forming a fluid tight seal by action of expansion of the hydrophilic composition. In such a case the member acts as a valve for permitting or preventing fluid flow through the catheter.
