Abstract
The balloon catheter comprises a shaft with an elongated dilatation balloon mounted in the vicinity of the distal end thereof. Member for preventing expansion of balloon segments are mounted on shaft proximally of the balloon and comprise an armature enclosed in a sleeve moveable over a proximal portion of the balloon.
Claims10
A method of dilating a stenosis comprising:
- (a) providing a catheter comprising a tubular shaft having proximal and distal portions;
- a dilatation balloon attached to the distal portion of the shaft;
- and a metal reinforced sleeve disposed about the shaft and adapted for longitudinal movement to cover at least a portion of the dilatation balloon;
- (b) positioning the metal reinforced sleeve to cover a portion of the balloon thereby forming a covered balloon portion and an uncovered balloon portion;
- (c) locking the reinforced sleeve while it is over the covered balloon portion;
- (d) disposing the uncovered balloon portion at a treatment site;
- and
- (e) radially expanding the uncovered balloon portion.
