1. A guidewire comprising:
- an elongated shaft including a length, a proximal section and a distal section;
a tubular attachment member disposed about a portion of the shaft;
a coil member disposed over at least a portion of the distal section, wherein the coil member is directly attached to the shaft at a first location along the length of the shaft, the coil member being connected to the tubular attachment member, wherein the first location along the length of the shaft is proximal of the tubular attachment member, and wherein the coil member extends both proximally and distally of the tubular attachment member; and
wherein the tubular attachment member is connected to the elongated shaft using a first attachment technique, and the coil member is connected to the tubular attachment member using a second attachment technique different from the first attachment technique.

Abstract
Alternative designs, materials and manufacturing methods for guidewires. Some embodiments pertain to a composite guidewire having proximal and distal section, and a connector adapted and configured for permanently joining the proximal section to the distal section. In some embodiments, at least one of the sections is made of a linear-elastic nickel-titanium alloy. Several alternative guidewire tip constructions and/or designs including methods and techniques of construction are also disclosed.
