Abstract
This invention is directed at an intravascular balloon catheter. The most important aspect of this invention is the catheter tip which is small, soft and truncated. The tip member has a proximal end and a distal end. The proximal end is secured to the distal end of the inner tubular member of the catheter shaft. The distal end has proximal and distal leading edges which reduce the overall profile of the catheter. Moreover, the catheter tip is formed from pliant materials so that trauma to the blood vessel walls can be minimized.
Claims14
A balloon catheter, comprising:
- an elongated shaft having a proximal end, a distal end, and proximal and distal sections disposed therebetween;
- an inflatable member disposed on the distal shaft section and having a proximal end, a distal end at a location proximal to the shaft distal end, and an interior chamber;
- an inflation lumen extending within at least a portion of the elongated shaft to a location proximal to the shaft distal end and in fluid communication with the inflatable member interior chamber;
- a guidewire receiving lumen defined, at least in part, by a tubular member sealingly secured to the inflatable member distal end, and extending through at least the distal section of the elongated shaft to the shaft distal end, and having a distal tip with proximal and distal edges on opposite sides of the distal tip and a face tapering in a distal direction from the proximal edge to the distal edge.
