Abstract
Systems and methods of electrical stimulation for intra and extra vascular treatment of a subject are provided. The device includes a first electrode, a second electrode, and a controller. The controller is configured to apply an electrical current between the first and second electrodes. The electrical current follows a path between the first and second electrodes and through a portion of the subject that includes a blockage.
Claims4
A method of ablating a blockage in a blood vessel of a subject, comprising:
- positioning a first electrode internal to the subject and proximate to a first portion of an outer surface of a blood vessel that includes the blockage;
- positioning a second electrode internal to the subject and proximate to a second portion of the outer surface of the blood vessel,
- wherein the first electrode and the second electrode are positioned external to the blood vessel and proximate to the blockage;
- and
- conducting pulses of an electrical current between the first electrode and the second electrode and along a path that includes the blockage, wherein the pulses are conducted at a frequency configured to ablate the blockage and facilitate blood flow in the blood vessel.
