Patent Images
1. A catheter comprising:
- an elongate first tubular member having a proximal section, a distal section, and a lumen extending therethrough;
a balloon associated with the distal section of the first tubular member, the balloon having a proximal end and a distal end; and
a wire disposed in at least the distal section of the first tubular member, the wire disposed in a spiral configuration and at least partially embedded in the tubular member, the wire including at least a first marker section of radiopaque material and a second marker section of radiopaque material, the first and second marker sections each formed of a varied density of the wire with the first marker section disposed proximate the proximal end of the balloon and the second marker section disposed proximate the distal end of the balloon.

Abstract
A catheter for delivering a stent includes an outer tube having a proximal end, a distal end and a wall defining a lumen; an inner tube disposed within the outer tube and defining a lumen for a guidewire, wherein a portion of a length of the inner tube is wrapped around with a spiral-shaped wire; a balloon sealingly connected to the inner tube and the outer tube adjacent the distal ends thereof, the balloon defining an interior volume and having an exterior surface; and a marker made from a wire of a highly radiopaque and ductile material, wherein the wire is wrapped in a plurality of at least partially overlapping layers such that the marker is flexible along the length of the catheter.
