Patent ID: 8715205

Claim:
A wire guide configured for navigation through a lumen and for having a medical device advanced over the wire guide, the wire guide comprising: an elongate shaft comprising a proximal portion and a distal portion, the distal portion comprising a first interlocking connector at a distal end of the shaft, the distal portion having a first diameter; and a loop portion comprising a deformable loop having a continuous perimeter surrounding an opening defined therethrough and the loop portion comprising a second interlocking connector at a proximal end of the loop portion, the second interlocking connector extending proximally from the deformable loop and configured for connecting with the first interlocking connector of the shaft and forming a connection between the first interlocking connector and the second interlocking connector at the distal end of the shaft so that the deformable loop extends distal to the connection and the shaft when the first and second interlocking connectors are connected and the deformable loop having a second diameter defined at the widest portion of the perimeter that is greater than the first diameter; wherein the connection provides for transmission of torque from the proximal portion of the shaft to the loop along a longitudinal axis of the shaft and wherein the second interlocking connector is configured for removably connecting with the first interlocking connector so that the second interlocking connector is removable from the first interlocking connector with the wire guide position within the lumen.
