Abstract
Ablation catheters and systems include flexible catheter tips with at least one positioning element and ports for delivery of an ablative agent to a target tissue. The positioning element is used to define a treatment zone and position the catheter proximate the target tissue for ablation. Ablative fluid is delivered to the target tissue at subtherapeutic, therapeutic, or supratherapeutic doses over different time periods, with rest periods between each dose, to cause effective ablation of the target tissue.
Claims13
A catheter assembly for vapor-based ablation therapy, comprising:
- a tubular body having a proximal end, a distal end, and an internal lumen extending therebetween defined by a longitudinal axis, wherein at least a portion of the internal lumen has a cross-section defined by opposed arcuate lobes separated by a central region that is constricted relative to the opposed arcuate lobes;
- a plurality of electrodes extending parallel to the longitudinal axis of the internal lumen and passing through the opposed arcuate lobes and central region of the lumen, wherein the plurality of electrodes is electrically coupled to a controller and configured to receive radiofrequency energy from the controller to heat a fluid within the lumen to form an ablative vapor;
- and
- ports extending along the tubular body that place the internal lumen in communication with an exterior of the catheter assembly, wherein the ports are positioned distal to the plurality of electrodes.
