1. A device, comprising:
- a main body portion defining a proximal end and a distal end and including a preshaped portion having a predefined bend between the proximal and distal ends having a predefined bend and configured to bend out of the predefined bend in response to an application of a force and return to the predefined bend in response to removal of the force;
a deflectable portion associated with the distal end of the main body portion and deflectable relative to the main body portion; and
at least one operative element carried by the deflectable portion.

Abstract
Compound steering assemblies, usable in both diagnostic and therapeutic applications, enable a physician to swiftly and accurately steer the distal section of the catheter in multiple planes or complex curves to position and maintain ablation and/or mapping electrodes in intimate contact with an interior body surface.

16. A catheter, comprising:
-
a main body portion defining a proximal end and a distal end and including a preshaped portion having a predefined bend located proximal of, and substantially adjacent to, the distal end, the preshaped portion having a predefined bend, defining a preshaped portion plane, and configured to bend out of the predefined bend in response to an application of a force and return to the predefined bend in response to removal of the force; a deflectable portion, including a steering spring defining first and second sides and configured to bend in the preshaped portion plane, associated with the distal end of the main body portion and deflectable relative to the main body portion; first and second steering wires connected to first and second sides of the steering spring; and at least one electrode carried by the catheter deflectable portion. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
