Publication number: 20220296294Abstract: Cardiac ablation catheters include an outer balloon positioned at a distal end of the catheter and configured to have an inner balloon disposed therein. The outer balloon is inflated with a first fluid that has a temperature less than 100 degrees Celsius, while the inner balloon is inflated with heated vapor. An area of contact between the two balloons, comprising a surface area less than the total surface area of either balloon, creates a hot zone for ablating cardiac tissue through the transfer of thermal energy from the contact area to the cardiac tissue.Type: ApplicationFiled: April 7, 2022Publication date: September 22, 2022Inventors: Virender K. Sharma, Kevin Holbrook, Holger Friedrich, Eric Steven Fain

Publication number: 20150150508Abstract: An intravascular electrode device for use in neuromodulation includes an anchor expandable from a radially compressed position to a radially expanded position. A lead extends from the anchor and has at least one conductor extending through it. A flex circuit is coupled to the anchor and comprises a flexible insulative substrate, a plurality of electrodes carried by the substrate, and a plurality of conductive traces carried by the substrate, each trace electrically coupled to an electrode and a conductor. Expansion of the anchor within a blood vessel biases the electrodes into contact with the surrounding blood vessel wall. An exemplary anchor includes a first portion having expansion forces sufficient to bias the electrodes against the vessel wall for mapping and chronic stimulation, and a second portion having greater radial expansion forces sufficient to chronically engage the vessel wall once an optimal electrode location has been selected.Type: ApplicationFiled: February 11, 2015Publication date: June 4, 2015Inventors: Richard A.
