Abstract
The present invention relates to a combination device comprising two catheters, or a dual catheter assembly, for use in vascular procedures wherein the shaft of the first catheter functions as a guidewire for the second catheter. The dual catheter assembly comprises a first balloon catheter and a second balloon catheter wherein the second balloon catheter is slidably disposed on the shaft of the first balloon. In preferred embodiments, the first catheter is a low profile balloon on a wire catheter and the second catheter is a full size balloon catheter having a plurality of balloons mounted thereon. Optionally, a stent is carried by at least one of the balloons on the second catheter. In more preferred embodiments, the second catheter includes a manifold that may be used to inflate and deflate any combination of the plurality of balloons via a single port. The dual catheter assembly of the present invention is especially useful in vascular procedures such as angioplasty, progressive/multiple angioplasty, and stent delivery.
