1. An embolic chain, comprising:
- an elongated tether member; and
,at least two embolic chain members, each of which being fixed to said tether member;
said at least two chain members being composed of an electrically conductive material, such that contact with powered electrical contacts positioned within a lumen of a catheter generate heat sufficient to break said elongated tether member.

Abstract
A catheter system utilizing one or more sensors is described. The catheter can be used as part of an embolic coil system, guidewire system, or combined embolic coil/guidewire system where the devices interact with the catheter system. A variable detachment embolic coil system and guidewire system are also described.
