Abstract
Abstract A wire for opening the obstructed part of a blood vessel comprising a plurality of projections or grooves formed on the forward end zone of a flexible or resilient wire body, or spiral parts provided starting at the tip of the wire body spaced apart from each other and left after a part of the material wire body corresponding to said spiral parts is cut away.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
40 words
A wire for coronary revascularization, said wire being adapted to be inserted into a catheter, characterized in that a plurality of projections or grooves are formed within a range of a distal end of a flexible or elastic wire body.
Claim 2
Dependent Claim
39 words
A wire for coronary revascularization, according to claim 1, characterized in that each of said projections is made of a material selected from the group consisting of a plastic material, a high-electricity resistive material and a high magnetic material.
Claim 3
Dependent Claim
54 words
A wire for coronary revascularization, said wire being adapted to be inserted into a catheter, characterized in that a spiral element is provided in spaced relation to a distal end of a flexible or elastic wire body, and that a portion of the wire body within a range of the spiral element is resected.
Claim 4
Dependent Claim
35 words
A wire for coronary revascularization, according to claim 3, characterized in that said spiral element is made of a material selected from the group consisting of a high-electricity resistive material and a high magnetic material.
Claim 5
Dependent Claim
26 words
A wire for coronary revascularization, according to any one of claims 1 ∼ 4, characterized in that an elastic core is embedded into the wire body.
Claim 6
Dependent Claim
42 words
A wire for coronary revascularization, according to any one of claims 1 ∼ 5, characterized in that the wire body is bent at a location between the distal end of the wire body and the projections, the grooves or the spiral element.
Claim 7
Dependent Claim
49 words
A wire for coronary revascularization, according to any one of claims 1 ∼ 6, characterized in that a passage is formed in the wire body, and that the passage is open to a surface of the wire body within a range of the distal end of the wire body.
Claim 8
Dependent Claim
21 words
A wire for coronary revascularization, according to claim 7, characterized in that said passage is a passage for supplying a drug.
Claim 9
Dependent Claim
34 words
A wire for coronary revascularization, according to claim 7, characterized in that said passage is a passage through which a glass fiber is inserted, and that a laser is applicable through the glass fiber.
Claim 10
Dependent Claim
77 words
A wire for coronary revascularization, said wire being adapted to be inserted into a catheter, characterized in that a core is provided within a flexible or elastic wire body, that a spiral element made of a high-electricity resistive material is arranged in spaced relation to a distal end of the wire body and in connected relation to said core, and that high frequency current is applied to the spiral element so as to be capable of heating.
Claim 11
Dependent Claim
53 words
A wire for coronary revascularization, said wire being adapted to be inserted into a catheter, characterized in that a distal end of a flexible or elastic wire body is made of a high magnetic material, and that the distal end of the wire body is capable of heating by a high-frequency magnetic field.
