Abstract
A medical device is disclosed, including a catheter body; an electrode array coupled to the catheter body, the electrode array being transitionable from a substantially linear configuration to a substantially helical configuration; and a fluid conduit coupled to the catheter body spaced apart from the electrode array, wherein the fluid conduit is transitionable from a substantially linear configuration to a substantially helical configuration. The device may include a fluid source in communication with the fluid conduit and a radiofrequency signal generator coupled to the electrode array.
Claims16
A medical device, comprising:
- a catheter body;
- a carrier arm coupled to the catheter body, the carrier arm including a plurality of electrodes and being transitionable from a substantially linear configuration to a substantially helical configuration;
- and
- a fluid conduit coupled to the catheter body, the fluid conduit being spaced apart from the carrier arm and being transitionable from a substantially linear configuration to a substantially helical configuration independently of the carrier arm.
A medical device, comprising:
- a catheter body;
- a carrier arm coupled to the catheter body, the carrier arm being transitionable from a substantially linear configuration to a substantially helical configuration;
- a fluid conduit extending adjacent to the carrier arm along substantially the entire length of the carrier arm;
- and
- a plurality of electrodes, each of the plurality of electrodes being disposed about both the carrier arm and the fluid conduit.
