Abstract
Treatment applicators and methods including treatment applicators for delivering electrical energy to a target tissue that are configured to reduce or eliminate arcing as well as provide enhance targeting to tissue surfaces or regions just below the surface of the tissue.
Claims34
A device for delivery of electrical treatment, the device comprising:
- an electrode housing extending from a distal end of the device;
- a first electrode or set of electrodes on or configured to extend from a distal outer face of the electrode housing, wherein the first electrode or set of electrodes are arranged about a first length along the distal outer face of the electrode housing;
- a second electrode or set of electrodes on or configured to extend from the distal outer face of the electrode housing, wherein the second electrode or set of electrodes are arranged about a second length along the distal outer face of the electrode housing that is parallel to the first length;
- and
- a suction port through the electrode housing and extending continuously along the distal outer face of the electrode housing between the first electrode or set of electrodes and the second electrode or set of electrodes, wherein the suction port extends further than the first length and the second length along the distal outer face of the electrode housing so as to prevent arcing between the first electrode or set of electrodes and the second electrode or set of electrodes.

A method, the method comprising:
- applying a distal end of a treatment applicator against a tissue;
- contacting the tissue with a first electrode or first set of electrodes positioned about a first length along a distal outer face of an electrode housing and a second electrode or second set of electrodes positioned about a second length along the distal outer face of the electrode housing of the treatment applicator;
- preventing arcing between the first electrode or first set of electrodes and the second electrode or second set of electrodes by applying suction through a suction port extending continuously along the distal outer face between the first electrode or first set of electrodes and the second electrode or second set of electrodes and longer than the first length and the second length so that the tissue contacts the suction port between and extending beyond on either side of the first electrode or first set of electrodes and the second electrode or second set of electrodes;
- and
- applying a pulsed electrical treatment to the tissue from the first electrode or first set of electrodes and the second electrode or second set of electrodes.

A device for delivery of electrical treatment, the device comprising:
- a first electrode or set of electrodes on or configured to extend from a tip portion of the device, wherein the first electrode or set of electrodes have a first length configured to be in contact with tissue when the tip portion of the device is positioned for electrical treatment;
- a second electrode or set of electrodes on or configured to extend from the tip portion of the device, wherein the second electrode or set of electrodes have a different polarity from the first electrode or set of electrodes;
- and
- a suction barrier extending continuously along and further than the first length and partially or fully surrounding the first electrode or set of electrodes so as to increase a strike distance between electrodes of different polarity and prevent arcing between the first electrode or set of electrodes and the second electrode or set of electrodes.
