Claim 0:
1. An electroporation catheter comprising:
a longitudinally-extending catheter shaft comprising a proximal end portion and a distal end portion that abuts the proximal end portion at an interface;
a plurality of electrodes disposed on the distal end portion of the catheter shaft and extending from a proximal electrode to a distal electrode, the proximal electrode positioned proximate the interface;
a handle attached to the proximal end portion of the catheter shaft; and
a loop member pull wire in a spiral configuration on an inside surface of the distal end portion of the catheter shaft for forming a loop member on the distal end portion of the catheter shaft, wherein the loop member pull wire is attached to an attachment point in the distal end portion of the catheter shaft and to an attachment point in the handle, wherein the loop member pull wire is in the spiral configuration on the inside surface of the distal end portion while the proximal end portion and distal end portion are in a straight conformation, and wherein, while the proximal end portion and the distal end portion are in the straight conformation, the loop member pull wire transitions from a straight configuration to the spiral configuration proximate the proximal electrode.
