First Claim
Patent Images
1. A guide wire tip, comprising:
- a core wire having a proximal end and a distal end, the core wire including a tapered portion, proximate the distal end, the tapered portion having a transverse cross-sectional area which generally decreases distally;
a distal portion of the core wire having a first transverse dimension greater than a second transverse dimension disposed perpendicularly to the first transverse dimension;
a tip disposed at the distal end of the core wire, the tip having a transverse cross-sectional area larger than the smallest transverse cross-sectional area of the tapered portion of the core wire;
a coil extending over the core wire to the tip, the coil extending over at least a portion of the tapered portion; and
a radiopaque sheath comprised of a flexible polymeric material loaded with a radiopaque material;
the radiopaque sheath overlaving the distal portion of the core wire.

Abstract
A guide wire tip including a core wire having a proximal end and a distal end. The core wire includes a tapered portion proximate the distal end. The tapered portion has a transverse, cross-sectional area which generally decreases distally. The tip is disposed at the distal end of the core wire. The tip has a transverse, cross-sectional area larger than the smallest transverse cross-sectional area of the tapered portion of the core wire. A coil extends over the core wire to the tip. The coil extends over at least a portion of the tapered portion. A radiopaque sheath is disposed proximate the tip and between the core wire and the coil.
