Abstract
The invention provides a deflectable catheter capable of forming many variable radius spiral forms from a single, flexible, distal end section. In one aspect, the catheter employs a variable radius control wire to extend or deform a pre-formed loop structure into a three dimensional spiral-like form or geometry. The ability of a single catheter to create a multitude of shapes and sizes allows users to access to a number of anatomical areas without changing the catheter during a procedure or treatment. In another aspect, the invention encompasses methods of producing deflectable variable radius catheters, where two or more regions of the catheter having common control wires are fused or formed onto one another.
