Abstract
Abstract Catheter for use in catheter procedures. The catheter includes a balloon carried at the distal end of an elongate shaft. A mechanism is included for providing a generally open perfusion passage while the balloon is in an inflated state. The perfusion passage provides both branch and distal perfusion. A mechanism is secured against the balloon for supporting the perfusion passage while the balloon is in an inflated state, and a mechanism is provided for retaining the balloon shape under pressure.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
80 words
A balloon catheter, comprising: an elongate shaft having a proximal end and a distal end, and defining an inflation lumen therethrough; a balloon connected to the shaft at the distal end; and a guidewire tube disposed proximate and externally of the distal end of the shaft, the tube having a proximal end and a distal end, the distal end being disposed proximally of the distal end of the balloon, and wherein the shaft at least partially surrounds the guidewire tube.
Claim 2
Dependent Claim
80 words
A balloon catheter, comprising: an elongate shaft having a proximal end and a distal end, and defining an inflation lumen therethrough; a balloon connected to the shaft at the distal end; and a guidewire tube disposed proximate and externally of the distal end of the shaft, the tube having a proximal end and a distal end, the distal end being disposed proximally of the distal end of the balloon, and wherein the shaft at least partially surrounds the guidewire tube.
Claim 3
Dependent Claim
22 words
The catheter of claim 1, wherein the passage has a maximum width that is greater than the width of the side opening.
Claim 4
Dependent Claim
14 words
The catheter of claim 1, wherein the passage is located adjacent the inflation lumen.
Claim 5
Dependent Claim
19 words
The catheter of claim 3, wherein the inflation lumen is located along a longitudinal center axis of the balloon.
Claim 6
Dependent Claim
23 words
The catheter of claim 1, further comprising a support member positioned within the passage for supporting the passage during inflation of the balloon.
Claim 7
Dependent Claim
21 words

Claim 12
Dependent Claim
27 words
The catheter of claim 9, wherein the shape retaining member includes a support member positioned within the passage for supporting the passage during inflation of the balloon.
Claim 13
Dependent Claim
16 words
The catheter of claim 1, wherein the passage is formed by the exterior of the balloon.
Claim 14
Independent Claim
133 words
A method of providing access to a vessel side branch from a location proximal of an inflated balloon, comprising the steps of: providing a balloon catheter including a shaft having a proximal end and a distal end, and a balloon assembly disposed proximate the distal end of the shaft, the balloon assembly having a proximal end, a distal end and a side; defining a passage extending distally into the balloon assembly such that the passage has a first opening proximate the proximal end of the balloon and a more distally disposed second opening at the side of the balloon assembly; and disposing the balloon assembly in a vessel such that the balloon assembly is disposed adjacent a side branch vessel opening such that the second opening is adjacent the side branch vessel opening.
Claim 15
Independent Claim
133 words
A method of providing access to a vessel side branch from a location proximal of an inflated balloon, comprising the steps of: providing a balloon catheter including a shaft having a proximal end and a distal end, and a balloon assembly disposed proximate the distal end of the shaft, the balloon assembly having a proximal end, a distal end and a side; defining a passage extending distally into the balloon assembly such that the passage has a first opening proximate the proximal end of the balloon and a more distally disposed second opening at the side of the balloon assembly; and disposing the balloon assembly in a vessel such that the balloon assembly is disposed adjacent a side branch vessel opening such that the second opening is adjacent the side branch vessel opening.
Claim 16
Dependent Claim
28 words
The method in accordance with claim 13, further comprising the steps of providing a generally cylindrical, expandable metallic member, and disposing the cylindrical member around the balloon assembly.
Claim 17
Dependent Claim
33 words
