Abstract
A catheter having an elongate shaft including a plurality of apertures disposed along at least a length of the shaft to facilitate bending. The catheter includes an inflatable balloon, wherein a subset of the plurality of apertures provides fluid communication from an inflation lumen to the inflatable balloon.
Claims20
A balloon catheter, comprising:
- a first tubular member;
- a second tubular member disposed about the first tubular member, the second tubular member having a proximal region and a distal region;
- wherein one or more cuts are formed in the second tubular member;
- a coating disposed along at least the proximal region of the second tubular member;
- wherein the coating fluidly seals the one or more cuts along the proximal region of the second tubular member;
- a balloon coupled to the distal region of the second tubular member, wherein a portion of the distal region of the second tubular member extends inside the balloon and includes one or more cuts therein, wherein a proximal waist of the balloon extends over a distal region of the coating;
- and
- wherein an inflation lumen is defined between the first tubular member and the second tubular member.
5 more elements
A balloon catheter, comprising:
- an inner tubular member defining a guidewire lumen;
- an outer tubular member disposed about at least a portion of the inner tubular member;
- wherein the outer tubular member has one or more slots formed therein;
- wherein the outer tubular member has a coated region and at least one uncoated region;
- a balloon coupled to the outer tubular member, wherein a portion of the outer tubular member extends inside the balloon and includes one of the uncoated regions;
- and
- wherein at least a section of the balloon is disposed along the uncoated region, wherein a proximal waist of the balloon extends over a portion of the coated region.
4 more elements
A medical device, comprising:
- a tube having a proximal region, a middle region, a distal region, a length extending between the proximal and distal regions, the tube defining a lumen;
- wherein a single helical cut is formed in the tube, the single helical cut extending along the entire length of the tube;
- a coating disposed along the middle region of the tube;
- wherein the coating fluidly seals the helical cut along the proximal region of the tube;
- an inner tubular member disposed within the lumen of the tube, wherein the inner tubular member is separated from the tube by a space, and wherein the space between the tube and the inner tubular member defines an inflation lumen;
- and
- wherein the distal and proximal regions of the tube are free of the coating such that fluid can move between the inflation lumen and an exterior surface of the tube.
