Abstract
Abstract A balloon catheter comprising a body and first and second arms attached to one end of the body. A common inflation lumen extends along the body and branches into each of the arms. An expandable balloon is provided on each arm so as to be in fluid communication with the lumen of each arm. The catheter further includes a guide wire lumen in each of the arms. A method for dilating a narrowed bifurcated vessel is also disclosed.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
94 words
A balloon catheter, comprising an elongate main body having a proximal end and a distal end and a main lumen extending there through, a joint coupled to the distal end of the elongate body and having a partition for dividing the main lumen into at least first and second fluid passages first and second arms, each coupled to the joint and each having an interior lumen in fluid communication with a respective one of first and second passages; and a balloon mounted on each arm at a location that is distal of the joint.
Claim 2
Dependent Claim
94 words
A balloon catheter, comprising an elongate main body having a proximal end and a distal end and a main lumen extending there through, a joint coupled to the distal end of the elongate body and having a partition for dividing the main lumen into at least first and second fluid passages first and second arms, each coupled to the joint and each having an interior lumen in fluid communication with a respective one of first and second passages; and a balloon mounted on each arm at a location that is distal of the joint.
Claim 3
Dependent Claim
45 words
A balloon catheter according to claim 1, wherein at least one of the first and second arms includes a guide wire lumen which terminates in a guide wire exit port at a location distal to the joint for allowing rapid exchange of a guide wire.
Claim 4
Dependent Claim
30 words
A balloon catheter according to claim 1, further including a guide wire lumen extending through the main body, the joint and at least one of the first and second arms.
Claim 5
Dependent Claim
31 words
A balloon catheter according to claim 1, wherein the joint includes a partition for dividing the main lumen into at least a first passage, a second passage, and a third passage.
Claim 6
Dependent Claim
31 words
A balloon catheter according to claim 1, further including a guide wire fixedly attached to at least one of the first and second arms at an end distal to the joint.
Claim 7
Dependent Claim
17 words
A balloon catheter according to claim 1, further including a sleeve mounted about one of the balloons.
Claim 8
Dependent Claim
18 words
A balloon catheter according to claim 1, wherein at least one of the balloons comprises a non-compliant material.
Claim 9
Dependent Claim
15 words
A balloon catheter according to claim 1, further including a coating of a pharmaceutical substance.
Claim 10
Dependent Claim
20 words
A balloon catheter according to claim 1, further including a coating of a substrate for enhancing lubricity of the catheter.
Claim 11
Dependent Claim
33 words
A balloon catheter according to claim 1, further including means for restricting a flow of fluid through the lumen of at least one of the arms to provide staggered inflation of the balloons.
Claim 12
Dependent Claim
27 words
A balloon catheter according to claim 1, wherein the balloons are offset, staggered, to expand a bifurcated vessel within which the balloons are positioned to different diameters.
Claim 13
Dependent Claim
18 words
A balloon catheter of claim 1, where each balloon is tapered to suit the variation in vessel diameter.
Claim 14
Dependent Claim
13 words
A balloon catheter of claim 1, where the balloons have a perfusion capability.
Claim 15
Independent Claim
194 words
A method for dilating an obstruction in a bifurcated vessel and delivering a stent, the method comprising: providing a balloon catheter having a main body with a main lumen extending therethrough, a joint coupled to one end of the main body having a partition for dividing the main lumen into first and second fluid passages, and first and second arms coupled to the joint, each arm having a respective one of said first and second fluid passages and a guide wire lumen extending therethrough and first and second balloons mounted on respective ones of said first and second arms at a position distal to the joint; positioning a bifurcated stent onto the first and second balloons; placing a guide wire in each branch of the bifurcated vessel; advancing each of said first and second arms over guide wires, so as to move each guide wire into the guide wire lumen of each arm; maneuvering the catheter along the vessel to the obstruction, so as to position each of said first and second balloons within a branch of the bifurcated vessel; and expanding each balloon, so as to expand the bifurcated stent against the vessel.
Claim 16
Independent Claim
194 words
A method for dilating an obstruction in a bifurcated vessel and delivering a stent, the method comprising: providing a balloon catheter having a main body with a main lumen extending therethrough, a joint coupled to one end of the main body having a partition for dividing the main lumen into first and second fluid passages, and first and second arms coupled to the joint, each arm having a respective one of said first and second fluid passages and a guide wire lumen extending therethrough and first and second balloons mounted on respective ones of said first and second arms at a position distal to the joint; positioning a bifurcated stent onto the first and second balloons; placing a guide wire in each branch of the bifurcated vessel; advancing each of said first and second arms over guide wires, so as to move each guide wire into the guide wire lumen of each arm; maneuvering the catheter along the vessel to the obstruction, so as to position each of said first and second balloons within a branch of the bifurcated vessel; and expanding each balloon, so as to expand the bifurcated stent against the vessel.
Claim 17
Dependent Claim
29 words
A method as set forth in claim 14 further including the steps of: deflating the balloon; and removing the catheter from the vessel, while leaving the stent in position.
Claim 18
Independent Claim
166 words
A method for dilating an obstruction in a bifurcated vessel, the method comprising: providing a balloon catheter having a main body with a main lumen extending therethrough, a joint coupled to one end of the main body having a partition for dividing the main lumen into first and second fluid passages, and first and second arms coupled to the joint, each arm having a respective one of said first and second fluid passages and a guide wire lumen extending therethrough and first and second balloons mounted on respective ones of said first and second arms at a position distal to the joint; placing a guide wire in each branch of the bifurcated vessel; advancing each arm over a guide wire, so as to move each guide wire into the guide wire lumen of each arm; maneuvering the catheter along the bifurcated vessel to the obstruction, so as to position each balloon within a branch of the bifurcated vessel; and expanding each balloon with the bifurcated vessel.
Claim 19
Independent Claim
166 words
A method for dilating an obstruction in a bifurcated vessel, the method comprising: providing a balloon catheter having a main body with a main lumen extending therethrough, a joint coupled to one end of the main body having a partition for dividing the main lumen into first and second fluid passages, and first and second arms coupled to the joint, each arm having a respective one of said first and second fluid passages and a guide wire lumen extending therethrough and first and second balloons mounted on respective ones of said first and second arms at a position distal to the joint; placing a guide wire in each branch of the bifurcated vessel; advancing each arm over a guide wire, so as to move each guide wire into the guide wire lumen of each arm; maneuvering the catheter along the bifurcated vessel to the obstruction, so as to position each balloon within a branch of the bifurcated vessel; and expanding each balloon with the bifurcated vessel.
Claim 20
Dependent Claim
23 words
A method as set forth in claim 16 further including the steps of: deflating the balloon; and removing the catheter from the vessel.
