Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
110 words
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.
Claim 2
Independent Claim
110 words
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.
Claim 3
Dependent Claim
14 words
The method of claim 1 wherein the sleeve is reinforced with a metal coil.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein the sleeve is reinforced with a metal braid.
Claim 5
Dependent Claim
13 words
The method of claim 1 wherein the metal is a high density metal.
Claim 6
Dependent Claim
10 words
The method of claim 4 wherein the metal is tungsten.
Claim 7
Independent Claim
154 words
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 proximal the balloon; (c) disposing the dilatation balloon at a treatment site; (d) dilating the stenosis with the balloon; (e) withdrawing the catheter; (f) positioning the metal reinforced sleeve to cover a portion of the balloon thereby forming a covered balloon portion and an uncovered balloon portion; (g) locking the reinforced sleeve while it is over the covered balloon portion; (h) disposing a radially collapsed stent about the uncovered balloon portion; (i) disposing the stent at the treatment site; and (j) radially expanding the uncovered portion of the balloon thereby expanding the stent.
Claim 8
Independent Claim
154 words
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 proximal the balloon; (c) disposing the dilatation balloon at a treatment site; (d) dilating the stenosis with the balloon; (e) withdrawing the catheter; (f) positioning the metal reinforced sleeve to cover a portion of the balloon thereby forming a covered balloon portion and an uncovered balloon portion; (g) locking the reinforced sleeve while it is over the covered balloon portion; (h) disposing a radially collapsed stent about the uncovered balloon portion; (i) disposing the stent at the treatment site; and (j) radially expanding the uncovered portion of the balloon thereby expanding the stent.
Claim 9
Dependent Claim
14 words

Claim 10
Dependent Claim
14 words
The method of claim 6 wherein the sleeve is reinforced with a metal braid.
Claim 11
Dependent Claim
13 words
The method of claim 6 wherein the metal is a high density metal.
Claim 12
Dependent Claim
10 words
The method of claim 9 wherein the metal is tungsten.
