Ablation device with guide sleeves
First Claim
1. An energy delivery device for treating a patient by electroporation (EP) comprising:
- a probe body having a plurality of circumferentially arranged openings at a predetermined distance from a distal end of the probe body;
at least three guide sleeves positioned inside the probe body and adapted to be deployed outside of the probe body through a respective opening and into tissue of the patient, the at least three guide sleeves being adapted to deploy at predetermined circumferential angles and uniformly spaced relative to each other such that the circumferential angle between any two of the at least three adjacent deployed guide sleeves is substantially the same; and
a plurality of elongate electrode elements, each having an outer layer comprised of an insulative material, each elongate electrode element adapted to receive EP pulses as electrical treatment energy from an energy source and adapted to be deployed into the tissue through a corresponding deployed guide sleeve.

Abstract
An energy delivery device for treating a patient includes a probe body; a plurality of guide sleeves positioned inside the probe body and adapted to be deployed radially away from the probe body and into tissue of the patient; and a plurality of elongate electrode elements each adapted to receive electrical treatment energy from an energy source and adapted to be deployed into the tissue through a corresponding deployed guide sleeve. The guide sleeves provide a structural pathway for guiding the electrodes along their intended trajectory and for determining the angle of deployment of the electrodes relative to the longitudinal axis of the probe body.

10. A method of treating a patient by electroporation (EP) comprising:
-
inserting a probe body of an energy delivery device into tissue of the patient, the probe body having a plurality of circumferentially arranged openings at a predetermined distance from a distal end of the probe body; deploying at least three guide sleeves positioned inside the probe body outside of the probe body through a respective opening and into the tissue, the at least three guide sleeves being adapted to deploy at predetermined circumferential angles and uniformly spaced relative to each other such that the circumferential angle between any two of the at least three adjacent deployed guide sleeves is substantially the same; deploying a plurality of elongate electrode elements through the at least three deployed guide sleeves using the at least three deployed guide sleeves as a guide, each of the plurality of elongate electrode elements having an insulation layer adapted to be deployed through the guide sleeves; and delivering EP pulses as electrical treatment energy to the tissue through the deployed electrodes. - View Dependent Claims (11, 12, 13, 14)
