Abstract:
An intravascular balloon catheter comprising:a) an elongated shaft having proximal and distal ends, an inflation lumen extending therein and a guidewire receiving lumen extending through at least a distal portion of elongated shaft; b) a proximal shaft section having proximal and distal ends and a portion of the inflation lumen; c) a distal shaft section having proximal and distal ends, a port in the distal end of the distal shaft section, at least part of the guidewire receiving lumen extending within the distal shaft section to the port in the distal end, and at least part of the inflation lumen extending within the distal shaft section to a location proximal to the distal end of the distal shaft section; d) an inflatable balloon on the distal shaft section having an interior in fluid communication with the inflation lumen therein; and e) an intermediate shaft section extending between the proximal and distal shaft sections having a tubular reinforcing member with proximal and distal ends, with a part of the inflation lumen extending within the tubular reinforcing member and with the proximal end thereof secured to a distal extremity of the proximal shaft section; f) an inner tubular member which extends from the distal end to the proximal end of the catheter and which has an interior defining at least in part the guidewire receiving lumen; and g) an outer tubular member which extends from the proximal end of the inflatable member to the proximal end of the catheter, which is disposed about the inner tubular member in the distal shaft section and defines at least in part the portion of the inflation lumen in the distal shaft section therebetween, which is disposed about the intermediate section and which is disposed about the proximal shaft section.
