Abstract
Abstract The wire guide is formed of a flexible stranded wire having a coating extending from the proximal end to rigidify the wire from the proximal end to an intermediate point. The wire remains flexible from the intermediate point to the distal end and a nose is fused to the distal end to prevent fraying of the filaments of the wire.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
55 words
A wire guide for a catheter comprising a length of stranded wire having a flexible section of a diameter of from about 0.008 inches to 0.062 inches extending to a distal end and a rigid section extending from said flexible section to a proximal end and a nose at said distal end of said wire.
Claim 2
Dependent Claim
55 words
A wire guide for a catheter comprising a length of stranded wire having a flexible section of a diameter of from about 0.008 inches to 0.062 inches extending to a distal end and a rigid section extending from said flexible section to a proximal end and a nose at said distal end of said wire.
Claim 3
Dependent Claim
16 words
A wire guide as set forth in claim 1 wherein said nose has a spherical shape.
Claim 4
Dependent Claim
25 words
A wire guide as set forth in claim 1 having a polymer coating over at least said flexible section to form a smooth biocompatible surface.
Claim 5
Dependent Claim
53 words
A wire guide for a catheter comprising a length of stranded wire having a flexible section extending to a distal end and a rigid section extending from said flexible section to a proximal end; and a metal nose of spherical shape fused to said distal end of said flexible section of said wire.
Claim 6
Dependent Claim
53 words
A wire guide for a catheter comprising a length of stranded wire having a flexible section extending to a distal end and a rigid section extending from said flexible section to a proximal end; and a metal nose of spherical shape fused to said distal end of said flexible section of said wire.
Claim 7
Dependent Claim
24 words
A wire guide as set forth in claim 4 wherein said flexible section has a diameter of from about 0.008 inches to 0.062 inches.
Claim 8
Dependent Claim
54 words
A wire guide for a catheter comprising a flexible length of stranded wire; a coating on a section of said wire extending from a proximal end to an intermediate point to rigidify said section; and a nose on a distal end of said wire to protect said wire from fraying at said distal end.
Claim 9
Dependent Claim
54 words
A wire guide for a catheter comprising a flexible length of stranded wire; a coating on a section of said wire extending from a proximal end to an intermediate point to rigidify said section; and a nose on a distal end of said wire to protect said wire from fraying at said distal end.
Claim 10
Dependent Claim

Claim 11
Dependent Claim
15 words
A wire guide as set forth in claim 6 wherein said coating is an epoxy.
Claim 12
Dependent Claim
21 words
A wire guide as set forth in claim 6 wherein said nose has a spherical shape and is made of metal.
Claim 13
Dependent Claim
22 words
A wire guide as set forth in claim 6 wherein said wire has a diameter of about 0.008 inches to 0.062 inches.
Claim 14
Dependent Claim
26 words
A wire guide as set forth in claim 6 having a polymer coating at least over a distal end thereof to form a smooth biocompatible surface.
Claim 15
Dependent Claim
65 words
A wire guide comprising a length of stainless steel stranded wire of a diameter of from about 0.008 inches to 0.062 inches; an epoxy coating on a section of said wire extending from a proximal end to an intermediate point to rigidify said section; and a spherical metal nose integral with said wire at a distal end thereof to retain said wire from fraying thereat.
Claim 16
Dependent Claim
65 words
A wire guide comprising a length of stainless steel stranded wire of a diameter of from about 0.008 inches to 0.062 inches; an epoxy coating on a section of said wire extending from a proximal end to an intermediate point to rigidify said section; and a spherical metal nose integral with said wire at a distal end thereof to retain said wire from fraying thereat.
