1. A method of making a guidewire, the method comprising:
- providing a metallic elongated guidewire shaft;
providing a metallic structural member configured to be connected to the elongated guidewire shaft;
disposing the structural member adjacent the elongated shaft in a predetermined position;
disposing a heat activated attachment material adjacent the elongated shaft and the structural member, the heat activated attachment material comprising solder or brazing material;
heating the heat activated attachment material using LASER energy such that the heat activated attachment material adjoins the elongated shaft and the structural member; and
allowing the heat activated attachment material to cool and attach the elongated shaft and the structural member.

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.
