Abstract:
A balloon catheter comprising:an outer tubular member having a tubular wall and a lumen extending throughout the length thereof, said outer tubular member further having a proximal end and a distal end, said tubular wall having an inner surface and an outer surface; an inner tubular member having a tubular wall and a lumen extending throughout the length thereof, said inner tubular member further having a proximal end and a distal end, said tubular wall having an inner surface and an outer surface; said inner tubular member being disposed coaxially within the lumen of the outer tubular member, said outer surface of the inner tubular member being bonded to said inner surface of the outer tubular member at a plurality of discrete locations longitudinally spaced along the length of the inner tubular member thereby forming a plurality of tack junctions said tack junctions have a length in a range of about 0.01 to 0.1 inch; an inflatable balloon having a main body portion, a proximal portion, and a distal portion, said proximal portion and said distal portion extending from said main body portion, said proximal portion of the balloon being bonded to the distal end of the outer tubular member and the distal portion of the balloon being bonded to the distal end of the inner tubular member; and, a coupling member having a lumen extending therethrough, said coupling member being mounted on the proximal end of the outer tubular member and the lumen of the coupling member communicating with the lumen between the outer tubular member and the inner tubular member so that fluid may be injected into the lumen of the coupling member to inflate the balloon.
