Claim:
1. An electrophysiology (EP) catheter comprising: a handle; a tubular catheter body having a proximal region coupled to a neck region which further couples to a distal portion which when in a non-compressed state is predisposed into a single shallow helical fixed-diameter loop configuration having a periphery of said loop directly coupled to the neck region at a periphery of the loop such that a central axis of the tubular catheter body is offset from a central axis of the single shallow helical fixed-diameter loop configuration; a flat wire assembly entirely disposed between the handle and the distal portion; an activation wire anchored to the flat wire assembly near the neck region; and a plurality of electrodes coupled to the single shallow helical fixed-diameter loop distal portion; wherein the distal portion has a first diameter that is less than a second diameter of the proximal region, the neck region transitioning the second diameter with the first diameter; and wherein the catheter further comprises a braided structure embedded near a junction of the neck region adjacent the distal single shallow helical fixed-diameter loop configuration.
