Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
72 words
A thin wire comprising a radioactive tip for use in the prevention of restenosis of an artery following arterial trauma, said thin wire being configured so that said radioactive tip can be inserted temporarily at the site of an arterial wall trauma and then be withdrawn and serves when so inserted to prevent restenosis of the artery at the trauma site, said radioactive tip including a beta-particle emitter radioisotope and emitting beta-particles.
Claim 2
Dependent Claim
22 words
A thin wire according to Claim 1, wherein the wire comprises said beta-particle emitter radioisotope incorporated into the material of the wire.
Claim 3
Dependent Claim
22 words
A thin wire according to Claim 1, wherein the wire comprises said beta-particle emitter radioisotope plated onto the surface of the wire.
Claim 4
Dependent Claim
24 words
A thin wire according to any one of Claims 1 to 3, wherein said beta-particle radioisotope has a half-life of less than 100 days.
Claim 5
Dependent Claim
18 words
A thin wire according to Claim 4, wherein said beta-particle emitter radioisotope is vanadium 48 or gold 198.
Claim 6
Dependent Claim
20 words
A thin wire according to any one of Claims 1 to 5, wherein said wire is coated with anti-thrombogenic material.
Claim 7
Dependent Claim
20 words
A thin wire according to any one of claims 1 to 3, wherein said beta-particle emitter radioisotope is phosphorous 32.
