Patent ID: 7678129

Claim:
An embolic protection device that locks to any point along a guide wire, comprising: an elongated guide wire core, the core having a proximal end and a distal end; a first guide wire coil, the first guide wire coil having a proximal end and a distal end, wherein the first guide wire coil is constructed of a plurality of turns of wire radially disposed about the distal guide wire core, and the proximal end of the guide wire coil is affixed to the guide wire core adjacent to the distal end of the guide wire core; a filter assembly having a proximal end and a distal end, disposed on the guide wire core; and a second guide wire coil, the second guide wire coil having a proximal end and a distal end, wherein the second guide wire coil is constructed of a plurality of turns of wire, and the proximal end of the second guide wire coil is coupled to the distal end of the filter assembly, wherein the second guide wire coil is configured to overlay the first guide wire coil such that turns of the second guide wire coil interlace with turns from the first guide wire coil to lock the second guide wire coil to the first guide wire coil.
