Abstract
A tissue treatment assembly comprising an elongate flexible energy delivery device extending along a longitudinal axis and terminating at a distal opening and a circuit assembly including a plurality of conductors wrapped in a spiral configuration around the elongate flexible energy delivery device.
Claims18
A tissue treatment assembly, comprising:
- an elongate flexible catheter extending along a longitudinal axis and terminating at a distal opening, wherein the elongate flexible catheter includes a lumen extending along the longitudinal axis and terminating at the distal opening;
- and
- a circuit assembly including a plurality of conductors wrapped in a spiral configuration around an exterior surface of the catheter and around the lumen extending therethrough, wherein the spiral configuration terminates proximally of the distal opening, and wherein at least one of the plurality of conductors of the circuit assembly is coupled to an electrode.
A method of treating tissue, comprising:
- directing an elongate flexible catheter within a body lumen, the elongate flexible catheter extending along a longitudinal axis and terminating at a distal opening, the elongate flexible catheter includes a lumen extending along the longitudinal axis and terminating at the distal opening;
- and
- conducting energy through a circuit assembly including a plurality of conductors wrapped in a spiral configuration around an exterior surface of the catheter and around the lumen extending therethrough, wherein the spiral configuration terminates proximally of the distal opening, and wherein at least one of the plurality of conductors of the circuit assembly is coupled to an electrode.
