摘要:
A deflectable, flexible device includes an elongate body, a convoluted tip portion at a distal end of the elongate body, and a lumen to receive one or more wires. The convoluted tip portion includes an electroformed pleated region which is formed by electrodepositing a metal on a mandrel having a pleated region. The convoluted tip portion may be hermetically sealed to permit repeated sterilization. The electroformed pleated region may include one or more fluid emission orifices. The convoluted tip portion extends or bends in response to fluid pressure manipulation, contact with tissue, manipulation with an internal spring or wire, or by a user pushing, pulling, or twisting the catheter directly or via an introducer sheath or the like. The convoluted tip portion may further include an RF ablation element or other energy-driven technique to create continuous linear lesions or a sensing element.
