Abstract
Abstract An apparatus for improved centering of a device which is intended to penetrate a severe occlusion of a body lumen. The apparatus includes a substantially tubular member having an exit port; an inflatable member having a distal end; wherein the exit port is not distal to the inflatable member. Such an apparatus allows for better fluoroscopic visualization, and therefore placement, of the apparatus with respect to the lesion.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
45 words
A device for treating an occluded body lumen, said device comprising a proximal end and a distal end; a substantially tubular member comprising an exit port; and an inflatable member having a distal end; wherein the exit port is not distal to the inflatable member.
Claim 2
Independent Claim
45 words
A device for treating an occluded body lumen, said device comprising a proximal end and a distal end; a substantially tubular member comprising an exit port; and an inflatable member having a distal end; wherein the exit port is not distal to the inflatable member.
Claim 3
Dependent Claim
36 words
The device according to claim 1 , wherein said inflatable member further comprises a proximal portion and a distal portion, and wherein the exit port is substantially contiguous with the distal portion of the inflatable member.
Claim 4
Dependent Claim
34 words
The device according to claim 1 , wherein said inflatable member further comprises a proximal portion and a distal portion, and the exit port is proximal to the distal end of the inflatable member.
Claim 5
Independent Claim
46 words
An apparatus for centering a recanalizing device within a body lumen comprising a proximal end and a distal end; a substantially tubular member comprising an exit port; and an inflatable member having a distal end; wherein the exit port is not distal to the inflatable member.
Claim 6
Independent Claim
46 words
An apparatus for centering a recanalizing device within a body lumen comprising a proximal end and a distal end; a substantially tubular member comprising an exit port; and an inflatable member having a distal end; wherein the exit port is not distal to the inflatable member.
Claim 7
Dependent Claim
35 words
The apparatus according to claim 4 , wherein the inflatable member further comprises a proximal portion and a distal portion; and the exit port is substantially contiguous with the distal end of the inflatable member.
Claim 8
Dependent Claim
34 words
The apparatus according to claim 4 , wherein the inflatable member further comprises a proximal portion and a distal portion; and the exit port is proximal to the distal end of the inflatable member.
Claim 9
Independent Claim
69 words
A method of making an inflatable member for use in a device for treating an occluded lumen, said method comprising the steps of: providing an inflatable member comprising an interior surface, an exterior surface, a proximal shaft, a middle portion, and a distal shaft; inverting the exterior surface of the proximal shaft such that the exterior surface of the proximal shaft faces the exterior surface of the distal shaft.
Claim 10
Independent Claim
69 words
A method of making an inflatable member for use in a device for treating an occluded lumen, said method comprising the steps of: providing an inflatable member comprising an interior surface, an exterior surface, a proximal shaft, a middle portion, and a distal shaft; inverting the exterior surface of the proximal shaft such that the exterior surface of the proximal shaft faces the exterior surface of the distal shaft.
Claim 11
Independent Claim
118 words
A method of making a catheter for treating an occluded lumen, said method comprising the steps of: providing an inflatable member comprising an interior surface, an exterior surface, a proximal shaft, a middle portion, and a distal shaft; inverting the exterior surface of the proximal shaft such that the exterior surface of the proximal shaft faces the exterior surface of the distal shaft; placing a first tubular member over the exterior surface of the distal shaft; affixing the exterior surface of the distal shaft to the first tubular member; placing a second tubular member over the exposed interior surface of the proximal shaft; and affixing the exposed interior surface of the proximal shaft to the second tubular member.
Claim 12
Independent Claim
118 words
A method of making a catheter for treating an occluded lumen, said method comprising the steps of: providing an inflatable member comprising an interior surface, an exterior surface, a proximal shaft, a middle portion, and a distal shaft; inverting the exterior surface of the proximal shaft such that the exterior surface of the proximal shaft faces the exterior surface of the distal shaft; placing a first tubular member over the exterior surface of the distal shaft; affixing the exterior surface of the distal shaft to the first tubular member; placing a second tubular member over the exposed interior surface of the proximal shaft; and affixing the exposed interior surface of the proximal shaft to the second tubular member.
