Systems and methods for electrosurgical tissue revascularization
First Claim
1. A method of revascularizing a region of tissue at a target site comprising:
- positioning an electrode terminal in close proximity to tissue in a region of the target site;
applying high frequency voltage to the electrode terminal, the high frequency voltage being sufficient to promote revascularization of tissue in the region of the target site;
introducing at least a distal end of an electrosurgical probe into a patient'"'"'s knee;
positioning the distal end of the probe in close proximity to a meniscus within the knee; and
forming a hole within the meniscus from an inner aspect of the meniscus to an outer aspect of the tissue.

Abstract
Systems, apparatus and methods are provided for canalizing or boring channels, divots, trenches or holes through tissue to revascularize the region around this tissue. In one method, an electrode terminal is positioned in close proximity to a target site and a high frequency voltage difference is applied between the electrode terminal and a return electrode to volumetrically remove or ablate tissue at the target site. The electrode terminal(s) may be translated relative to the body structure during or after the application of electrical energy to sculpt a void within the body structure, such as a hole, channel, stripe, crater, divot or the like. The present invention may be useful for revascularization of a healthy meniscus, or a torn or damaged meniscus during a repair procedure. For example, channels may be formed from the inner aspect to the outer aspect of the meniscus to promote direct communication between blood within the outer aspect and that of existing meniscus vasculature to increase blood flow therein.

16. A method of revascularizing a region of a patient'"'"'s meniscus tissue comprising:
-
positioning a distal end of an electrosurgical instrument adjacent to a region of the meniscus tissue; applying sufficient energy to the region of meniscus tissue to remove a portion of tissue within said region to promote blood flow to said region; and forming a hole from an inner portion of the meniscus tissue to the outer portion of the meniscus tissue. - View Dependent Claims (17, 18, 19)
