摘要： Systems, apparatus, and methods are provided for promoting blood flow to a target tissue. In one aspect, the invention involves canalizing or boring channels, divots, trenches or holes through an avascular connective tissue, or through a tissue having sparse vascularity, such as a tendon or a meniscus, in order to increase blood flow within the tissue. In one method, an active electrode is positioned in close proximity to a target site on a tendon, and a high frequency voltage difference is applied between the active electrode and a return electrode to selectively ablate tendon tissue at the target site, thereby forming a channel or void in the tendon. The active electrode(s) may be moved relative to the tendon during, or after, the application of electrical energy to damage or sculpt a void within the tendon, such as a hole, channel, crater, or the like. In another aspect of the invention, an electrosurgical probe is used to elicit a wound healing response in a target tissue, such as an injured tendon, in order to stimulate vascularization of the target tissue. The present invention may also be used for vascularization of a torn or damaged tissue in conjunction with a surgical repair procedure.
