Abstract
An angioplasty catheter and method for making and using the same. An angioplasty catheter comprises an inner tube having a proximal end, a distal end, and a lumen extending therethrough; an outer tube disposed over the inner tube, the outer tube having a proximal end and a distal end; a balloon coupled to the distal end of the outer tube; an inflation lumen defined between the inner tube and the outer tube, the inflation balloon in fluid communication with the balloon; and a support block coupled to the inner tube. In addition, a method for manufacturing an angioplasty catheter is disclosed.
Claims18
An elongate medical device, comprising:
- an outer tubular member having a proximal end, a distal end and a lumen extending therethrough;
- an elongate shaft disposed within at least a portion of the lumen of the outer tubular member, the elongate shaft having a proximal end and a distal end;
- a balloon coupled to the distal end of the outer tubular member;
- an inflation lumen defined between the elongate shaft and the outer tubular member, the inflation lumen in fluid communication with the balloon;
- and
- a support block secured to the elongate shaft, the support block including a fluid passageway in fluid communication between the inflation lumen and the balloon, and an abutment surface abutting the distal end of the outer tubular member, wherein at least a portion of the support block extends distal of the distal end of the outer tubular member;
- wherein the support block further comprises a proximal region and a distal region, at least a portion of the proximal region having an outer diameter less than the lumen of the outer tubular member, and at least a portion of the distal region having an outer diameter greater than the lumen of the outer tubular member.
