Abstract
A catheter for ablation including a catheter shaft, a balloon at a distal end of the catheter shaft, and a microporous portion. The balloon is configured to support conductors and electrodes and contain a fluid. The microporous portion is coupled to the balloon to allow the fluid to flow out of the balloon and includes a plurality of apertures configured to prevent large air bubbles from exiting the balloon.
Claims20
A catheter for ablation, the catheter comprising:
- a catheter shaft;
- a balloon disposed at a distal end of the catheter shaft, the balloon configured to support conductors and electrodes and further configured to contain a fluid;
- a microporous portion coupled to the balloon and configured to allow the fluid to flow out of the balloon;
- and
- wherein the microporous portion includes a plurality of apertures configured to prevent air bubbles with a diameter larger than 50 microns from exiting the balloon.
2 more elements
A method to manufacture a catheter configured for ablation comprising the steps of:
- forming a microporous portion
- forming a balloon, including attaching a microporous portion;
- attaching conductors to the balloon;
- and
- attaching the balloon assembly to the catheter.
2 more elements
A method of using a system for ablation comprising:
- inserting a catheter comprising a shaft and a balloon into a patient;
- navigating and extending the catheter such that the catheter is in contact with a cardiac tissue of the patient;
- implementing ablation treatment through the electrodes to the cardiac tissue;
- and
- retracting the catheter such that a fluid passes through a plurality of openings of the balloon at a flow rate configured to prevent air bubbles with a diameter greater than a maximum value from passing through the balloon.
