摘要： Systems, apparatus, and methods are provided for promoting blood flow to a target tissue. In one variation, the invention involves creating a pattern of voids in 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. This also includes using a template device to assist in the creation of the pattern of voids. Also included is an electrosurgical device with a self-contained fluid supply for providing conductive fluid to the target tissue or to active electrodes of the device.

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.

摘要： Systems and methods are provided for applying a high frequency voltage in the presence of an electrically conductive fluid to create a relatively low-temperature plasma for ablation of tissue adjacent to, or in contact with, the plasma. In one embodiment, an electrosurgical probe or catheter is positioned adjacent the target site so that one or more active electrode(s) are brought into contact with, or close proximity to, a target tissue in the presence of electrically conductive fluid. High frequency voltage is then applied between the active electrode(s) and one or more return electrode(s) to non-thermally generate a plasma adjacent to the active electrode(s), and to volumetrically remove or ablate at least a portion of the target tissue. The high frequency voltage generates electric fields around the active electrode(s) with sufficient energy to ionize the conductive fluid adjacent to the active electrode(s). Within the ionized gas or plasma, free electrons are accelerated, and electron-atoms collisions liberate more electrons, and the process cascades until the plasma contains sufficient energy to break apart the tissue molecules, causing molecular dissociation and ablation of the target tissue.

摘要： The present invention provides systems, apparatus and methods for removing the outer layer, or stratum corneum, of a patient's skin. In one aspect of the invention, a method includes positioning an active electrode adjacent to or near a target site on a patient's outer skin, and applying a sufficient high frequency voltage to the active electrode to remove the stratum corneum without removing the entire epidermis layer. In this manner, the present invention removes dead and/or damaged skin cells on the surface of the skin which improves the overall appearance of the skin. In addition, this process helps to stimulate the bodies own rejuvenation process. In some embodiments, this rejuvenation process occurs by the actual removal of the stratum corneum, which accelerates the regrowth of new cell layers in the skin. In other embodiments, thermal energy is applied to the underlying epidermis and/or dermis to stimulate the growth of new collagen. In both of these embodiments, the skin appears healthier and, in some cases, small wrinkles are removed or reduced.

摘要： Systems and methods are provided for performing electrosurgical interventions, such as selectively contracting soft collagen tissue and other body structures, while limiting thermal damage or molecular dissociation of such tissue and limiting the thermal damage to tissue adjacent to and underlying the treatment site. The systems and methods of the present invention are particularly useful for surgical procedures in electrically conducting environments, such as arthroscopic procedures in the joints, e.g., shoulder, knee, hip, hand, foot, elbow or the like. The present invention is also useful in relatively dry environments, such as treating and shaping the cornea, and dermatological procedures involving surface tissue contraction of tissue underlying the surface of the skin for tissue rejuvenation, wrinkle removal and the like.

摘要： Methods and apparatus for resecting and ablating tissue at a target site of a patient, the apparatus including a probe having an elongate shaft. The shaft includes a shaft distal end portion and a shaft proximal end portion, and a resection unit located at the shaft distal end portion. The resection unit includes a resection electrode support and at least one resection electrode arranged on the resection electrode support. The at least one resection electrode includes a resection electrode head. The probe and resection electrode head are adapted for concurrent electrical ablation and mechanical resection of target tissue. The shaft may include at least one digestion electrode capable of aggressively ablating resected tissue fragments. At least one fluid delivery port on the shaft distal end portion may provide an electrically conductive fluid to the resection unit or to the target site. The shaft may include at least one aspiration port, located proximal to the resection unit, for aspirating excess or unwanted fluids and resected tissue fragments from the target site. The at least one aspiration port is coupled to an aspiration lumen. The at least one digestion electrode may be arranged within the aspiration lumen for ablation of tissue fragments therein. In use, the digestion and resection electrodes of the probe are coupled to a high frequency power supply. A surgical kit comprising the probe is also disclosed, together with a method of making the probe.

摘要： Apparatus and methods for treating an intervertebral disc by ablation of disc tissue. A method of the invention includes positioning at least one active electrode within the intervertebral disc, and applying at least a first high frequency voltage between the active electrode(s) and one or more return electrode(s), wherein the volume of the nucleus pulposus is decreased, pressure exerted by the nucleus pulposus on the annulus fibrosus is reduced, and discogenic pain of a patient is alleviated. In other embodiments, a curved or steerable probe is guided to a specific target site within a disc to be treated, and the disc tissue at the target site is ablated by application of at least a first high frequency voltage between the active electrode(s) and one or more return electrode(s). A method of making an electrosurgical probe is also disclosed.

摘要： The present invention provides systems and methods for selectively applying electrical energy to a target location within the head and neck of a patient's body, particularly including tissue in the ear, nose and throat. The present invention includes a channeling technique in which small holes or channels are formed within tissue structures in the mouth, such as the tonsils, tongue, palate and uvula, and thermal energy is applied to the tissue surface immediately surrounding these holes or channels to cause thermal damage to the tissue surface, thereby stiffening the surrounding tissue structure. Applicant has discovered that such stiffening of certain tissue structures in the mouth and throat helps to prevent the tissue structure from obstructing the patient's upper airway during sleep.
