1. An elongate medical device, comprising:
- an inner elongate member having a proximal portion and a distal portion;
a helically wound continuous wire comprising a single filament including a proximal portion having a first cross-sectional profile, a distal portion having a second cross-sectional profile different from the first cross-sectional profile, and a transition region between the first portion and the second portion, the proximal portion of the continuous wire being disposed about the proximal portion of the inner elongate member and the distal portion of the continuous wire being disposed about the distal portion of the inner elongate member;
an outer tubular member disposed about at least a part of the proximal portion of the inner elongate member and at least a part of the proximal portion of the helically wound continuous wire, the outer tubular member including a wall and a plurality of slots extending through the wall; and
a distal tip portion extending over and surrounding at least a part of the distal portion of the inner elongate member and at least a part of the distal portion of the helically wound continuous wire.

Abstract
An elongate medical device including an inner elongate member, a reinforcing member, and an outer tubular member is described. The reinforcing member may be a helically wound continuous wire including a first portion having a first cross-sectional profile, a second portion having a second cross-sectional profile, and a transition region located between the first portion and the second portion. The first cross-sectional profile may be different from the second cross-sectional profile. In some embodiments, the first cross-sectional profile may be circular or non-circular and the second cross-sectional profile may be circular or non-circular.

10. An elongate medical device, comprising:
-
an inner elongate tubular member having a proximal portion and a distal portion; a helically wound coil comprising a single filament, the single filament including a proximal portion having a proximal cross-sectional profile, a distal portion having a distal cross-sectional profile different from the proximal cross-sectional profile, and a transition region between the proximal portion and the distal portion, the continuous helical wire being disposed about the inner elongate tubular member such that the proximal portion of the continuous wire is disposed about the proximal portion of the inner elongate member and the distal portion of the continuous wire is helically is disposed about the distal portion of the inner elongate tubular member; an outer tubular member disposed about at least a part of the proximal portion of the inner elongate tubular member and helically wound coil, wherein a distal end of the outer tubular member is disposed proximate the transition region; and a distal tip portion extending over and surrounding the distal portion of the inner elongate member, the distal tip portion having a proximal end abutting the distal end of the outer tubular member. - View Dependent Claims (11, 12)
