Wire guide

A method for manufacturing a wire guide, the method comprising:

• providing a core member having proximal and distal ends and at least one recessed portion disposed therebetween;
• providing a first coiled member having proximal and distal ends, wherein the proximal end of the first coiled member is seated at least partially within the recessed portion of the core member, thereby forming a substantially flush exterior surface with the core member;
• providing a first set of adjacent turns of the first coiled member disposed at an attachment region to the core member, the attachment region disposed at the proximal end of the first coiled member, wherein the first set of adjacent turns comprise a first spacing relative to one another,
• providing a second set of adjacent turns disposed at a non-attachment region distal to the first set of adjacent turns, wherein the second set of adjacent turns comprise a second spacing relative to one another,
• wherein the first spacing is greater than the second spacing;
• and
• soldering the first coiled member to the core member in the vicinity of the recessed portion, wherein solder is disposed substantially within the first set of adjacent turns, such that the solder does not significantly increase the overall profile of the wire guide.

A wire guide suitable for use in a body vessel, the wire guide comprising:

• a core member having proximal and distal ends;
• and
• a first coiled member having proximal and distal ends disposed about a portion of the core member,
• wherein the first coiled member comprises a first set of adjacent turns disposed at an attachment region to the core member, the attachment region disposed at the proximal end of the first coiled member, wherein the first set of adjacent turns comprise a first spacing relative to one another,
• wherein the first coiled member further comprises a second set of adjacent turns disposed at a non-attachment region distal to the first set of adjacent turns, wherein the second set of adjacent turns comprise a second spacing relative to one another,
• wherein the first spacing is greater than the second spacing.
