MEDICAL DEVICE FOR NAVIGATION THROUGH ANATOMY AND METHOD OF MAKING SAME
First Claim
1. A medical device, comprising:
- an elongate core member having a proximal region and a distal region;
a tubular member disposed adjacent to the distal region, the tubular member having a plurality of slots formed therein and having a longitudinal axis;
wherein the slots are arranged in a plurality of groups;
wherein each of the groups includes slots that are disposed at the same position along the longitudinal axis of the tubular member;
wherein the plurality of groups includes a first group and a second group that is disposed adjacent to the first group;
wherein the first group includes two slots that are the same size; and
wherein the second group includes two slots that are different in size.

Abstract
Medical devices for navigation through anatomy, including guidewires, which may have a core wire, a slotted tubular member, or both. Embodiments may have coils, including non-circular cross-section edge-wound marker coils, extended coil tips, and soldered or glued mesial joint coils. Core wires may have a step, ridge, or taper at the joints to the tubular member, and may be flattened at the distal tip. Radiopaque material may be located inside the tubular member, and the distal tip may be heat treated to make it shapeable. Additional tubular members or coils may be used concentrically or in line and may enhance flexibility, provide radiopacity, reduce friction, or reduce material or manufacturing cost. Tubular members may be chamfered or tapered continuously or incrementally. Slots may be arranged in groups, such as groups of tree, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.
