1. An embolic coil delivery system comprising:
a catheter including a first contact and a second contact;
an embolic coil including two segments and a link;
the link including a proximal conductive sleeve, a distal conductive sleeve, and a degradable portion between the proximal and the distal conductive sleeves;
wherein a circuit is completed when the catheter's first and second contacts are in electrical communication with the link's proximal and distal conductive sleeves, and wherein the degradable portion degrades in response to current flowing through the completed circuit such that the two segments of the embolic coil detach from each other in response to the degradable portion degrading.
