Abstract
A balloon catheter includes an outer tube that has an inner surface and an inflation lumen and an inner tube that is disposed within the inflation lumen. The balloon catheter also includes a collar that has a proximal end coupled to a distal end of the outer tube, and a distal end. The collar is coupled to an edge of the distal end or the inner surface of the outer tube. The balloon catheter further includes a luminal space, which is defined by a space between the outer surface of the inner tube and the collar, and a balloon. The balloon has a proximal end coupled to the collar and a distal end coupled to the inner tube.
Claims32
A balloon catheter comprising:
- an outer tube including a distal end, an inner surface, a longitudinal axis, and an inflation lumen;
- an inner tube disposed within the inflation lumen of the outer tube, the inner tube including an outer surface and an inner lumen;
- a collar having a proximal end and a distal end, the proximal end of the collar coupled to the inner surface of the outer tube at the distal end of the outer tube such that the collar extends outwardly from the inflation lumen of the outer tube;
- a luminal space defined by a space between the outer surface of the inner tube and the collar;
- and
- a balloon having a proximal end and a distal end, the proximal end of the balloon being coupled to the collar at the distal end of the outer tube and the distal end of the balloon being coupled to the inner tube,
- wherein a coupling element is disposed between the outer tube and the balloon such that a distal most end face of the outer tube is directly coupled to the coupling element which is directly coupled to the balloon,
- wherein the collar includes a slot that extends radially around an outer circumference of the collar, wherein the collar is at least partially disposed around the outer surface of the inner tube and the inner tube partially extends through the slot when the inner tube is disposed within the inflation lumen of the outer tube.
A balloon catheter comprising:
- an outer tube having an outer diameter, an inner surface, a distal end, a longitudinal axis, and an inflation lumen;
- an inner tube disposed within the inflation lumen of the outer tube, the inner tube having an inner lumen including a coating solution deposited on the inner lumen;
- a collar having an outer diameter that is smaller than the outer diameter of the outer tube, a proximal end, and a distal end, the proximal end of the collar coupled to the inner surface of the outer tube at the distal end of the outer tube such that the collar extends outwardly from the inflation lumen of the outer tube, and the collar having a slot wherein the inner tube is disposed within the slot and partially extends through the slot when the inner tube is disposed within the inflation lumen of the outer tube, and the collar includes a luminal space defined by a space between the inner tube and collar;
- and
- a balloon having a proximal end and a distal end, wherein the proximal end of the balloon is coupled to the collar at the distal end of the outer tube and the distal end of the balloon is coupled to the inner tube, and the balloon includes an interior space that is in fluid communication with the outer tube through the luminal space of the collar allowing the balloon to be inflated from a deflated state to an inflated state,
- wherein a coupling element is disposed between the outer tube and the balloon such that a distal most end face of the outer tube is directly coupled to the coupling element which is directly coupled to the balloon.
