CATHETER SHAFT DESIGNS
First Claim
1. A catheter comprising:
- a hypotube defining a first lumen and having proximal and distal ends, proximal and distal portions, and an intermediate portion between the proximal and distal ends;
an inflation tube with distal and proximal ends, wherein the proximal end of the inflation tube is connected to the intermediate portion of the hypotube and is disposed over the distal portion of the hypotube, forming a second lumen therebetween; and
a guidewire tube with proximal and distal ends, the proximal end forming a guidewire port, the guidewire tube extending through an opening in the hypotube and distally through the hypotube, forming a guidewire lumen.

Abstract
Disclosed is a balloon catheter that can comprise an elongate support member, an inflation tube, a guidewire tube and a balloon. The guidewire tube can define a guidewire port at its proximal end, and can extend from the port through an opening in a wall of the elongate support member and distally through a first lumen of the elongate support member, in some cases to the distal end of the catheter. The inflation tube can be disposed over a distal portion of the elongate support member, a portion of the guidewire tube, a portion of the inner assembly, or any combination thereof, forming a second lumen. The distal end of the balloon can be attached to the guidewire tube and the proximal end of the balloon can be attached to the inflation tube. The inside of the balloon can be in fluid communication with the first lumen and with the second lumen, allowing the balloon to be inflated and/or deflated. The elongate support member can also have cuts in it. For example, the elongate support member can have apertures formed in it, or apertures and spiral cuts.

47. A method of making a balloon catheter comprising:
-
providing a hypotube and a guidewire tube; cutting the hypotube to form one or more cuts in a proximal portion of the hypotube and one or more cuts in a distal portion of the hypotube; forming an opening through the wall of the hypotube; passing the guidewire tube through the opening and distally through a lumen defined by the hypotube, forming an inner catheter assembly. - View Dependent Claims (48, 49, 50, 51)
