Abstract
Abstract Guidewires having a substantially permanent disposition or predispostion to assume the configuration of a coil are disclosed. The guidewire assumes a coiled configuration when not in use and a straight or substantially linear configuration when being used to place a medical device within the anatomy of a patient. Guidewires of invention advantageously reduces the likelihood that the guidewire will fall out of the sterile field during a medical procedure and become contaminated, requiring replacement. Methods for making the guidewire also are disclosed.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
57 words
An elongate, guidewire comprising a guidewire body having coupled distal, medial and proximal segments, wherein at least a substantial portion of at least one of said segments of the guidewire has a substantially permanent disposition to assume a coiled configuration whereby said segment has neither a time nor temperature dependent tendency to return to a non-coiled configuration.
Claim 2
Dependent Claim
57 words
An elongate, guidewire comprising a guidewire body having coupled distal, medial and proximal segments, wherein at least a substantial portion of at least one of said segments of the guidewire has a substantially permanent disposition to assume a coiled configuration whereby said segment has neither a time nor temperature dependent tendency to return to a non-coiled configuration.
Claim 3
Dependent Claim
21 words
A guidewire according to claim 1 wherein the segment having the disposition to assume a coiled configuration is the medial segment.
Claim 4
Dependent Claim
20 words
A guidewire according to claim 2 wherein substantially the entire medial segment has a disposition to assume a coiled configuration.
Claim 5
Dependent Claim
17 words
A guidewire according to claim 1 wherein the guidewire comprises a wire core and a coil wire.
Claim 6
Dependent Claim
22 words
A guidewire according to claim 4 wherein the wire core comprises stainless steel and the coil wire comprises an alloy of platinum.
Claim 7
Dependent Claim
28 words
A guidewire according to claim 1 wherein at least a substantial portion of the distal segment has a diameter which is less than that of the medial segment.
Claim 8
Dependent Claim
13 words
A guidewire according to claim 1 wherein the guidewire comprises a polymeric material.
Claim 9
Dependent Claim
75 words
A guidewire according to claim 1 wherein the guidewire comprises a core wire having distal and proximal ends, a coil wire having distal and proximal ends, and a safety wire, the proximal ends of the core wire and coil wire being essentially coterminous and attached to each other, the core wire terminating short of the coil wire distal end, and the safety wire is attached to the distal and proximal ends of the coil wire.
Claim 10
Dependent Claim
66 words
An elongate, guidewire comprising a guidewire body having coupled distal, medial and proximal segments, wherein at least a substantial portion of at least one of said segments of the guidewire has a substantially permanent disposition to assume a coiled configuration and said guidewire body comprises medical grade stainless steel whereby said segment has neither a time nor temperature dependent tendency to return to a non-coiled configuration.
Claim 11
Dependent Claim
66 words
An elongate, guidewire comprising a guidewire body having coupled distal, medial and proximal segments, wherein at least a substantial portion of at least one of said segments of the guidewire has a substantially permanent disposition to assume a coiled configuration and said guidewire body comprises medical grade stainless steel whereby said segment has neither a time nor temperature dependent tendency to return to a non-coiled configuration.
Claim 12
Dependent Claim
21 words
A guidewire according to claim 9, wherein the segment having the disposition to assume a coiled configuration is the medial segment.
Claim 13
Dependent Claim
20 words
A guidewire according to claim 9, wherein substantially the entire medial segment has a disposition to assume a coiled configuration.
Claim 14
Dependent Claim
17 words
A guidewire according to claim 9, wherein the guidewire comprises a wire core and a coil wire.
Claim 15
Dependent Claim
22 words
A guidewire according to claim 9, wherein the wire core comprises stainless steel and the coil wire comprises an alloy of platinum.
Claim 16
Dependent Claim
32 words
A guidewire according to claim 9, wherein at least a substantial portion of the guidewire body distal segment has a diameter which is less than that of the guidewire body medial segment.
Claim 17
Dependent Claim
72 words
A guidewire according to claim 9, wherein the guidewire comprises a core wire having a distal and proximal end, a coil wire having a distal and proximal end, the proximal ends of the core wire and coils wire being essentially coterminous and attached to each other, the core wire terminating short of the coil wire distal end, and a safety wire attached to the distal and proximal ends of the coil wire.
