Abstract
Abstract For producing annular color marks on a spirally shaped catheter guide wire, a guide wire is selectively heated within a tempering range of 200° C. to 360° C. at the points provided for the color marks so that permanent temper colorations of the steel are left at said points. The advantage involved therewith is that color marks may be produced by neither removing nor applying material, and the contour of the guide wire is not changed. Further, no foreign material adhering to the guide wire may get into the body of the patient.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
78 words
A catheter guide wire comprising: an elongated flexible body defining a smooth outer surface; the surface having at least one indicia extending along a predetermined length thereof; the smooth surface continuing throughout the predetermined portion along which the indicia extends; and the indicia being disposed a predetermined distance from a distal end of the body and being spaced regularly along the wire for indicating the length of said wire; and wherein said indicia are temper colors of steel.
Claim 2
Dependent Claim
78 words
A catheter guide wire comprising: an elongated flexible body defining a smooth outer surface; the surface having at least one indicia extending along a predetermined length thereof; the smooth surface continuing throughout the predetermined portion along which the indicia extends; and the indicia being disposed a predetermined distance from a distal end of the body and being spaced regularly along the wire for indicating the length of said wire; and wherein said indicia are temper colors of steel.
Claim 3
Dependent Claim
22 words
A catheter guide wire as in claim 1, wherein said wire comprises an elongated strand of at least one spirally wound wire.
Claim 4
Dependent Claim
29 words
A guide wire as in claim 2, wherein adjacent turns of said spirally wound wire are in contact; and, further comprising a core disposed within said spirally wound wire.
Claim 5
Dependent Claim
19 words
The catheter guide wire as in claim 2, wherein a front end of the guide wire may be hook-shaped.
Claim 6
Dependent Claim
19 words
The catheter guide wire as in claim 2, wherein a front end of the guide wire may be straight.
Claim 7
Dependent Claim
18 words
The catheter guide wire as in claim 2, wherein the length of said indicia is about 2 mm.
Claim 8
Dependent Claim
18 words
The catheter guide wire as in claim 1, wherein said wire is chosen from the group comprising steel.

Dependent Claim
84 words
A catheter guide wire comprising: an elongated flexible body defining a smooth outer surface; the surface having at least one indicia extending along a predetermined length thereof; the smooth surface continuing throughout the predetermined portion along which the indicia extends; and the indicia being disposed a predetermined distance from a distal end of the body and being spaced regularly along the wire for indicating the length of said wire; and said indicia are formed at a temperature range of 200 to 300 degrees Celsius.
Claim 12
Dependent Claim
84 words
A catheter guide wire comprising: an elongated flexible body defining a smooth outer surface; the surface having at least one indicia extending along a predetermined length thereof; the smooth surface continuing throughout the predetermined portion along which the indicia extends; and the indicia being disposed a predetermined distance from a distal end of the body and being spaced regularly along the wire for indicating the length of said wire; and said indicia are formed at a temperature range of 200 to 300 degrees Celsius.
Claim 13
Dependent Claim
122 words
A catheter guide wire comprising: an elongated flexible body defining a smooth exterior surface; the surface having at least one indicia extending along a predetermined portion thereof; the smooth surface extending throughout the predetermined portion along which the indicia extends; the indicia being disposed a predetermined distance from a distal end of the body; the body comprising a strand of at least one spirally wound wire about a core; the spirally wound wire and the core chosen from the group comprising steel; the body having a thickness of 1 mm, a length of at least 30 cm and a hook-shaped end; and the indicia chosen from the temper colors of steel and being visible from each peripheral point of the guide wire.
Claim 14
Dependent Claim
122 words
A catheter guide wire comprising: an elongated flexible body defining a smooth exterior surface; the surface having at least one indicia extending along a predetermined portion thereof; the smooth surface extending throughout the predetermined portion along which the indicia extends; the indicia being disposed a predetermined distance from a distal end of the body; the body comprising a strand of at least one spirally wound wire about a core; the spirally wound wire and the core chosen from the group comprising steel; the body having a thickness of 1 mm, a length of at least 30 cm and a hook-shaped end; and the indicia chosen from the temper colors of steel and being visible from each peripheral point of the guide wire.
