Abstract
A medical device includes a catheter shaft including a distal region and an inflatable balloon that is secured to the distal region of the catheter shaft. The inflatable balloon has an outer surface and defines a centerline when inflated. A blade extends over and is secured to the outer surface, the blade having a cutting edge extending from a distal end of the blade to a proximal end of the blade, when the inflatable balloon is inflated, the cutting edge extends to a maximum distance measured relative to the centerline of the inflatable balloon at the distal end of the blade and a minimum distance measured relative to the centerline of the inflatable balloon of the medical device at the proximal end of the blade.
Claims20
A medical device, comprising:
- a catheter shaft including a distal region;
- an inflatable balloon secured to the distal region of the catheter shaft, the inflatable balloon having an outer surface, the inflatable balloon defining a centerline when inflated;
- and
- a blade extending over and secured to the outer surface, the blade having a cutting edge extending from a distal end of the blade to a proximal end of the blade, when the inflatable balloon is inflated, the cutting edge tapers from a maximum distance measured relative to a centerline of the balloon at the distal end of the blade to a minimum distance measured relative to the centerline of the balloon at the proximal end of the blade.
A medical device, comprising:
- a catheter shaft including a distal region;
- an inflatable balloon secured to the distal region of the catheter shaft, the inflatable balloon including:
- a constant diameter middle section corresponding to where the polymeric pad is secured to the outer surface of the inflatable balloon;
- a distal region that tapers to a distal waist;
- and
- a proximal region that tapers to a proximal waist;
- a polymeric pad secured to the constant diameter middle section of the inflatable balloon;
- and
- a blade secured within the polymeric pad, the blade defining a tapered cutting edge extending from a distal end of the blade to a proximal end of the blade, the tapered cutting edge having a maximum blade height relative to the polymeric pad at the distal end of the blade and a minimum blade height relative to the polymeric pad at the proximal end of the blade.
A medical device, comprising:
- a catheter shaft including a distal region;
- an inflatable balloon secured to the distal region of the catheter shaft, the inflatable balloon including a tapered middle section corresponding to where the polymeric pad is secured to the outer surface of the inflatable balloon, the tapered middle section tapering from a maximum diameter near a distal region to a minimum diameter near a proximal region;
- a polymeric pad secured to the tapered middle section of the inflatable balloon;
- and
- a blade secured within the polymeric pad, the blade defining a cutting edge extending from a distal end of the blade to a proximal end of the blade.
