ABSTRACT:
A vascular catheter having an expandable cage mounted on the distal end of a tubular member which is radially expanded and contracted by means of a control wire which is secured to the distal end of the expandable cage. The control wire extends through a first inner lumen within the tubular member which extends along essentially the entire length thereof. A second inner lumen is provided in the distal portion of the tubular member which has a proximal port at least 15 but not more than 60 cm from the distal end of the catheter and a distal port which opens into the interior of the expandable cage. A guidewire or a low-profile steerable catheter is slidably disposed within the second lumen and a tubular member such as a slightly expanded coil through the expandable cage interior to facilitate the rapid exchange of the catheter. The catheter assembly is particularly adapted to hold open a blood vessel after a vascular procedure therein such as an angioplasty.
