Abstract
Abstract A stent delivery system (10) is provided for percutaneous insertion into a vessel of the human body in order to place a balloon expandable stent (32) at the site of an obstruction in the vessel. The stent delivery system (10) includes a balloon angioplasty catheter having a distal section with an inflatable balloon (34) located at the distal section of the balloon angioplasty catheter. A balloon expandable stent (32) is co-axially mounted on the inflatable balloon (34). A flexible guide wire (11) is fixedly attached to and extends distally from the distal section of the balloon angioplasty catheter. <IMAGE>

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
66 words
A stent delivery system for placing a stent in a vessel of the human body, the
stent delivery system comprising: a balloon angioplasty catheter having a distal section with an inflatable
balloon located at the distal section; a balloon expandable stent mounted on the inflatable balloon; and a flexible guide wire fixedly attached to and extending distally from the distal
section of the balloon angioplasty catheter.
Claim 2
Dependent Claim
18 words
The stent delivery system of claim 1 wherein the guide wire is substantially
straight over its entire length.
Claim 3
Dependent Claim
19 words
The stent delivery system of claim 1 wherein the guide wire has a distal
section that is substantially curved.
Claim 4
Dependent Claim
22 words
The stent delivery system of any preceding claim wherein the guide wire has
an outside diameter that is less than 0.035 inches.
Claim 5
Dependent Claim
18 words
The stent delivery system of claim 4 wherein the guide wire has an outside
diameter of 0.014 inches.
Claim 6
Dependent Claim
20 words
The stent delivery system of any preceding claim wherein the length of the
guide wire is less than 5 cm.
Claim 7
Dependent Claim
17 words
The stent delivery system of any preceding claim wherein the stent is
mechanically crimped onto the balloon.
Claim 8
Dependent Claim
16 words
The stent delivery system of any preceding claim wherein the stent is nested
onto the balloon.
Claim 9
Dependent Claim
37 words
The stent delivery system of any preceding claim wherein the balloon has a
longitudinal axis and the balloon is wrapped in a spiral around the balloon's
longitudinal axis prior to placement of the stent onto the balloon.
Claim 10
Dependent Claim
26 words
The stent delivery system of any preceding claim wherein the balloon is folded
with a multiplicity of wings for a balloon of a balloon angioplasty catheter.
Claim 11
Dependent Claim
55 words
The stent delivery system of any preceding claim wherein the balloon has a
proximal section that has the shape of a frustum of a cone when the balloon is fully
inflated and the balloon angioplasty catheter includes a proximal elastic band that is
wrapped around the proximal section of the balloon prior to balloon inflation.
Claim 12
Dependent Claim
55 words
The stent delivery system of any preceding claim wherein the balloon has a
distal section that has the shape of a frustum of a cone when the balloon is fully
inflated and the balloon angioplasty catheter includes a distal elastic band that is
wrapped around the distal section of the balloon prior to balloon inflation.
Claim 13
Dependent Claim
44 words
The stent delivery system of any preceding claim wherein the balloon has a
proximal end that is fixedly attached to a central tube having a central lumen through
which balloon inflation fluid can be injected or removed to respectively inflate or
deflate the balloon.
Claim 14
Dependent Claim
65 words
The stent delivery system of claim 13 wherein the central tube is attached to a
proximal tube that has a proximal end and a distal end, the proximal tube extending
for most of the length of the stent delivery system, the proximal tube having a Luer
fitting at its proximal end, the Luer fitting being adapted for connection to a source of
balloon inflation fluid.
Claim 15
Dependent Claim
33 words
The stent delivery system of claim 14 wherein the flexible guide wire has a
central core wire, the length of the core wire being substantially equal to the length of
the guide wire.
Claim 16
Dependent Claim
27 words
The stent delivery system of claim 14 wherein the flexible guide wire has a
central core wire that extends longitudinally throughout the entire length of the
balloon.
Claim 17
Dependent Claim
26 words
The stent delivery system of claim 16 wherein the proximal end of the core
wire is fixedly attached near the distal end of the proximal tube.
Claim 18
Dependent Claim
25 words
The stent delivery system of claim 16 wherein the proximal end of the core
wire is attached near the proximal end of the proximal tube.
Claim 19
Dependent Claim
24 words
The stent delivery system of any preceding claim wherein the balloon
overhang length beyond each edge of the stent is less than 1.0 mm.
Claim 20
Dependent Claim
24 words
The stent delivery system of any preceding claim, wherein the balloon
overhang length beyond each edge of the stent is less than 0.5 mm.
Claim 21
Dependent Claim
47 words
The stent delivery system of any preceding claim wherein the longitudinal
length of the stent when deployed is approximately equal to the length of the
cylindrical section of the inflated balloon thereby resulting in an approximately zero
length of balloon overhang beyond the edges of the stent.
Claim 22
Dependent Claim
17 words
The stent delivery system of any preceding claim, wherein the stent is
coaxially mounted on the balloon.
