Deflection mechanisms are disclosed that are positionable to deflecting portions of a flexible body, such as a catheter, in more than one direction in a single plane, as well as in more than one plane. The invention allows a distal portion of a catheter to be deflected more than 360 degrees to provide a loop.

Defined deflection structure

A method of promoting blood vessel growth includes the steps of providing a cryocatheter having a thermally transmission region; placing the cryocatheter proximate an area of tissue to be treated; cooling the thermally transmissive region of the cryocatheter proximate the area of tissue to a temperature sufficient to injure the area of tissue; allowing the area of tissue to warm; and removing the cryocatheter from the area of tissue. Prior, during or after the cooling step, the area of tissue can be mechanically traumatized, and drugs can be injected into the tissue.
