INTRAVASCULAR CATHETER WITH MEANS TO SEAL GUIDEWIRE PORT

摘要

This invention is directed to an intraluminal catheter (10), such as a dilatation catheter for angioplasty procedures, having an inner lumen (21) which is adapted to receive a guidewire (22) therein and to deliver inflation liquid to an inflatable member and which is provided with sealing means (16) to prevent the loss of inflation fluid through the guidewire port in the distal end of the catheter. The sealing means is actuated by inflation fluid under pressure which is introduced into the interior of the guidewire receiving inner lumen.
