Abstract
Abstract An occlusion catheter for use during therapeutic intervention of a blood vessel for flushing away debris indluding an elongated guide catheter (20) sized to be introduced into the blood vessel, an occlusion balloon (12) located at or near the distal end of the catheter and an inflation lumen (18) integral with the guide catheter and communicating with the interior of the balloon enabling the balloon to be inflated to form a seal between the balloon and the blood vessel wall. The balloon is capable of being expanded to at least 5 times its deflated diameter when inflated.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
An occlusion catheter for use during therapeutic intervention of a blood vessel for flushing away debris, characterised by an elongated guide catheter (20) sized to be introduced into the blood vessel lumen, an occlusion balloon (12) located on said guide catheter or near the distal end of said catheter, and an inflation lumen (18) integral with said guide catheter (20) and communicating with the interior of said balloon enabling the balloon to be inflated forming a seal between the balloon and a vessel wall proximally of the therapeutic intervention, said balloon being capable of expanding to at least five times its deflated diameter when inflated.
Claim 2
Dependent Claim
105 words
An occlusion catheter for use during therapeutic intervention of a blood vessel for flushing away debris, characterised by an elongated guide catheter (20) sized to be introduced into the blood vessel lumen, an occlusion balloon (12) located on said guide catheter or near the distal end of said catheter, and an inflation lumen (18) integral with said guide catheter (20) and communicating with the interior of said balloon enabling the balloon to be inflated forming a seal between the balloon and a vessel wall proximally of the therapeutic intervention, said balloon being capable of expanding to at least five times its deflated diameter when inflated.
Claim 3
Dependent Claim
26 words
An occlusion catheter as claimed in claim 1 characterised in that said lumen (18) of said guide catheter has an inner diameter of at least .068".
Claim 4
Dependent Claim
36 words
An occlusion catheter as claimed in claim 1, characterised in that said lumen (18) of said guide catheter has an inner diameter capable of permitting the passage of a dilatation balloon catheter and a treatment device.
Claim 5
Dependent Claim
96 words
A packaged catheter system for use in treating a stenosis in a cerebral vessel characterised by a guide catheter (20) having attached at its distal end an elastic occlusion balloon (12) capable of expanding to at least 500% of its deflated size without bursting, and having a guide lumen (18) extending therethrough for receiving at least one treatment device, said guide lumen having an inner diameter of at least .038"; instructions describing the use of the catheter to occlude a cerebral vessel during treatment of a stenosis, and a package containing the guide catheter and instructions.
Claim 6
Dependent Claim
96 words
A packaged catheter system for use in treating a stenosis in a cerebral vessel characterised by a guide catheter (20) having attached at its distal end an elastic occlusion balloon (12) capable of expanding to at least 500% of its deflated size without bursting, and having a guide lumen (18) extending therethrough for receiving at least one treatment device, said guide lumen having an inner diameter of at least .038"; instructions describing the use of the catheter to occlude a cerebral vessel during treatment of a stenosis, and a package containing the guide catheter and instructions.
Claim 7
Dependent Claim
24 words
A packaged catheter system as claimed in claim 4, characterised in that said inner diameter of said guide catheter (20) is at least .068".
Claim 8
Dependent Claim
77 words
An occlusion catheter for use during therapeutic intervention of a blood vessel for flushing away debris, characterised by a catheter (20), an occlusion balloon (12), attached proximally of the distal end of said catheter for occluding said blood vessel proximal a stenosis, a dilatation balloon disposed distal said occlusion balloon on said catheter for treating said stenosis, a first balloon inflation lumen for inflating said occlusion balloon, and a second inflation lumen for inflating said dilatation balloon.
Claim 9
Dependent Claim
77 words
An occlusion catheter for use during therapeutic intervention of a blood vessel for flushing away debris, characterised by a catheter (20), an occlusion balloon (12), attached proximally of the distal end of said catheter for occluding said blood vessel proximal a stenosis, a dilatation balloon disposed distal said occlusion balloon on said catheter for treating said stenosis, a first balloon inflation lumen for inflating said occlusion balloon, and a second inflation lumen for inflating said dilatation balloon.
