Abstract
The invention relates to a catheter device including a coil element comprised of NiCr60 alloy material, whose proximal radial end is coiled about the catheter shaft. The coil element and the thermal containment tube are configured so as to emit thermal energy. This is achieved by a catheter device adapted to deliver thermal energy from a source local to the body tissue to be ablated, adapted for connection to a thermal heat source at its distal end, a fluid conduit for passing a fluid into said ports for anchoring and filling the proximal cuff of the thermal energy device, a separate conduit for placement of necessary connective lines to the thermal energy element and monitoring device and a separate conduit for the drainage of bladder fluids during treatment.
Claims13
A device for treating tissue adjacent to a body lumen, said device comprising a catheter shaft insertable into the body lumen;
- a heating element coiled around and carried by the said catheter shaft;
- a dual-layered balloon around the said heating element around the said_catheter shaft, opposing ends of the said dual-layered balloon being sealingly connected to the said catheter shaft to form a fluid chamber between the said dual-layered balloon and the said_catheter shaft and a sensor chamber between the balloon layers of the said dual-layered balloon and a fluid lumen for delivery of a fluid in the said catheter shaft and the said fluid chamber in a defined fluid flow path to inflate the said dual-layered balloon into contact with the wall of the said body lumen.
