Abstract
A catheter assembly can include an elongated catheter having opposed proximal and distal end portions and having an axial lumen extending therethrough, the axial lumen configured to accommodate electrical wires. The assembly can include a distal electrode array configured to have a basket shape in a deployed position and configured to collapse in a collapsed position, the distal electrode array configured to extend from the distal end portion of the elongated catheter in the deployed position and to be selectively contained within the axial lumen or other sheath in the collapsed position.
Claims19
A catheter assembly comprising:
- an elongated catheter having opposed proximal and distal end portions and having an axial lumen extending therethrough, the axial lumen configured to accommodate electrical wires;
- and
- a distal electrode array configured to have a basket shape in a deployed position and configured to collapse in a collapsed position, the distal electrode array configured to extend from the distal end portion of the elongated catheter in the deployed position and to be selectively contained within the axial lumen or other sheath in the collapsed position.
The assembly any of the preceding claims wherein the ablation electrodes and/or the cap and/or the orientation electrodes are made of platinum iridium.
An ablation catheter system, comprising:
- a recorder module configured to receive sympathetic signals from the circumference of the artery to allow the location of the nerve path with the renal sympathetic over-activity;
- an ablation energy generator configured to output power to the ablation electrodes to cause tissue ablation;
- a switching module configured to switch between the recorder module and the ablation energy generator to switch between electrical mapping and ablation of a selected zone with the renal sympathetic over-activity utilizing the same electrode array.
An electrode array for renal ablation comprising a basket shape in a deployed position and configured to collapse in a collapsed position, the electrode array configured to extend from a distal end portion of an elongated catheter in the deployed position and to be selectively contained within the axial lumen or other sheath in the collapsed position.
