1. An angioplasty cutting device for balloon angioplasty of a stenotic lesion in a body vessel, the device comprising:
- a distal ring configured to be disposed at the distal end of the stenotic lesion relative to the device;
at least one strut attached to the distal ring and proximally extending therefrom, the at least one strut configured to be disposed at the stenotic lesion to engage the stenotic lesion for dilatation of the body vessel during angioplasty; and
a proximal ring configured to be disposed at the proximal end of the stenotic lesion relative to the device, the at least one strut being attached to the proximal ring and extending therefrom a predetermined length for delivery and retrieval of the device.

Abstract
An angioplasty cutting device for balloon angioplasty of a stenotic lesion in a body vessel. The device comprises a distal ring and a proximal ring. The device further comprises at least one strut attached to the distal ring and proximally extending to the proximal ring. The strut is configured to be disposed at the stenotic lesion to engage the stenotic lesion for dilatation of the body vessel during angioplasty. The strut extending from the proximal ring a predetermined length for delivery and retrieval of the device.

11. An atherosclerosis cutting device coaxially adaptable about an expandable balloon for angioplasty of a stenotic lesion in a body vessel, the device comprising:
-
a distal ring configured to be disposed adjacent the distal end of the balloon relative to the device;
a cutting body including a plurality of struts, each strut having a first portion and a second portion, each first portion being attached to the distal ring and extending longitudinally therefrom, the cutting body being radially expandable with the balloon to engage the stenotic lesion for dilatation of the body vessel during angioplasty; and
a proximal ring configured to be disposed adjacent the proximal end of the balloon relative to the device, each second portion being attached to the proximal ring, one of the struts extending therefrom a predetermined length for delivery and retrieval of the device. - View Dependent Claims (12, 13, 14, 15, 16, 17)
