Patent ID: 8545418

Claim:
A multiple-wire system for obtaining access through an occlusion within a blood vessel, comprising: a first wire configured for percutaneous insertion in the blood vessel towards a proximal surface of the occlusion, the first wire comprising: a first outer wire having a proximal end, a distal end, and a generally cylindrical outer surface, wherein the first outer wire includes an opening adjacent the distal end, an opening adjacent the proximal end, and a central lumen communicating therebetween; a first middle wire configured for insertion in the blood vessel through the central lumen of the outer wire, the first middle wire having a proximal end, a distal end and a generally cylindrical outer surface, wherein the first middle wire includes an opening adjacent the distal end, an opening adjacent the proximal end, and a central lumen communicating therebetween, wherein the first middle wire is longer than the first outer wire; and a first inner wire having a proximal end, a distal end, and a gradually tapered portion adjacent the distal end, wherein the first inner wire gradually tapered portion is configured to penetrate and pass through the occlusion, and wherein the gradually tapered portion comprises a first magnet having a diameter no greater than the gradually tapered portion; and a capture device configured for percutaneous insertion in the blood vessel towards a distal surface of the occlusion opposite the proximal surface, the capture device being operable to draw the distal end of the first wire to a position distal of the distal surface of the occlusion, wherein the capture device comprises a second magnet that is adapted to attract the first magnet.
