A micro-sized CAP (μCAP) employed to target glioblastoma tumors in the murine brain. Various plasma diagnostic techniques were applied to evaluate the physics of helium μCAP such as electron density, discharge voltage, and optical emission spectroscopy. The direct and indirect effects of μCAP on glioblastoma (U87MG-RedFluc) cancer cells in vitro were investigated and indicate that μCAP-generated short- and long-lived species and radicals [i.e. hydroxyl radical (OH), hydrogen peroxide (H2O2), nitrite (NO2-), et al] with increasing tumor cell death in a dose-dependent fashion. Translation of these findings to an in vivo setting demonstrates that intracranial μCAP is effective at preventing glioblastoma tumor growth in the mouse brain. The μCAP device can be safely used in mice, resulting in suppression of tumor growth. These initial observations establish the μCAP device as a potentially useful ablative therapy tool in the treatment of glioblastoma.

An electrode is located in the flow of gas exiting out of the first opening for igniting a plasma between the first opening and the tissue to be treated. Due to the secondary stream accompanying the primary stream, an ignition of the plasma is successful even if the instrument is at a relatively large distance from the tissue.

Systems and methods for electrosurgical myocardial revascularization

A method for transmyocardial revascularization of the heart of a patient includes positioning an active electrode surface in close proximity to a target site on the wall of a patient's heart, and applying high frequency voltage between the active voltage surface and a return electrode to ablate tissue at the heart wall. The high frequency voltage ablates, i.e. volumetrically removes the heart tissue, and the electrode surface is axially translated into the space vacated by the removed tissue to bore a channel through the heart tissue. The active electrode surface may be introduced into the thoracic cavity and placed adjacent the epicardium to form an inward channel toward the ventricular cavity, or it may be delivered into the ventricular cavity of the heart and positioned adjacent the endocardium to form a channel extending outward towards the epicardium. In either case, the channels formed through the myocardium promote direct communication between blood within the ventricular cavity and that of existing myocardial vasculature to increase blood flow to the heart tissue.

Electrically conducting liquid (50) is directed to the heart wall to provide a current flow path and high frequency voltage is applied to ablate or disintegrate tissue at the heart wall. The probe is then axially translated towards the ventricular wall to form a revascularizing channel or artificial vessel from the ventricle to the myocardium to increase blood flow therethrough.

Methods for electrosurgical treatment of spinal tissue

Systems, apparatus, and methods for treating spinal tissue and other body structures in open and endoscopic spine surgery to relieve symptoms, such as neck or back pain. In particular, the present invention provides methods for the controlled heating of various tissues in or around the vertebral column, including various interspinous tissues, such that spinal ligaments and cartilage surrounding the vertebrae and the facet joints are shrunk or tightened to stabilize the vertebral column of a patient. Thermal energy is applied to the target tissue in a subablation mode of an electrosurgical system to cause shrinkage of the tissue, thereby stiffening the interspinous tissue and stabilizing the vertebral column. In an exemplary embodiment, a high frequency RF voltage can be applied between one or more active electrode(s) and one or more return electrode(s) to heat a target interspinous tissue to within a temperature range at which irreversible shrinkage of the tissue occurs.

System and method for electrosurgical cutting and ablation

An electrosurgical probe (10) comprises a shaft (13) having an electrode array (12) at its distal end and a connector (19) at its proximal end for coupling the electrode array to a high frequency power supply (28). The shaft includes a return electrode (55, 56) recessed from its distal end and enclosed within an insulating jacket (18). The return electrode defines an inner passage (83) electrically connected to both the return electrode and the electrode array for passage of an electrically conducting liquid (50). By applying high frequency voltage to the electrode array and the return electrode, the electrically conducting liquid generates a current flow path between the target site and the return electrode so that target tissue may be cut or ablated. The probe is particularly useful in dry environments, such as the mouth or abdominal cavity, because the electrically conducting liquid provides the necessary return current path between the return electrode and the target site.

Electrosurgical treatment of tissue in electrically conductive fluid

A method is provided for applying electrical energy to a tissue structure within a patient's body. The method includes positioning an electrosurgical probe adjacent to the tissue structure so that an electrode array including a plurality of isolated electrode terminals is brought into at least partial contact with the body structure. A high frequency voltage is then applied between each electrode terminal within the electrode array and a common, return electrode. Current flow from the electrode terminals is selectively limited to minimize low electrical impedance paths emanating from the electrode array. The present invention takes advantage of the differences in electrical properties between a target tissue and the surrounding conductive liquid (e.g. isotonic saline irrigant) in the region immediately adjacent to the electrode array to ablate the target tissue while minimizing overheating of the surrounding liquid.

Shaped electrodes and methods for electrosurgical cutting and ablation

An electrosurgical system and method allow the surgical team to perform electrosurgical interventions, such as ablation and cutting of body structures, while limiting the depth of necrosis and limiting damage to tissue adjacent the treatment site. The system includes an electrosurgical probe having a shaft with a proximal end, a distal end, and at least one active electrode at or near the distal end. The active electrode includes at least one active portion having a surface geometry configured to promote substantially high electric field intensities and associated current densities between the active portion and the target site when a high frequency voltage is applied to the electrodes. These high electric field intensities and current densities are sufficient to break down the tissue by processes including molecular dissociation or disintegration. The high frequency voltage imparts energy to the target site to ablate a thin layer of tissue without causing substantial tissue necrosis beyond the boundary of the thin layer of tissue ablated. This ablative process can be precisely controlled to effect the volumetric removal of tissue as thin as a few layers of cells with minimal heating of or damage to surrounding or underlying tissue structures.

Power supply for limiting power in electrosurgery

A high frequency power supply for applying electrical energy to a target site on or within a patient's body includes an electrical output driver, an output current sensor detecting the current output from the driver, and a power limiting device coupled to the current sensor during normal conditions, the power limiting device operates on a continuous basis. When current output exceeds a predetermined threshold level, the power limiting device is adapted to reduce power on the output driver to a standby mode. The power limiting device operates on a periodic detection or duty cycle when in the standby mode. The power limiting device switches into the stand-by mode to prevent excessive power drains. The power supply operates at a low power, pulsatile manner when an attached probe is in conductive or isotonic fluid but is not engaging body tissue or near a high impedance source. In this pulsatile mode, the power supply operates in a cyclical manner, typically at a predetermined duty cycle.

Dual mode electrosurgical clamping probe and related methods

The present invention provides systems, apparatus and methods for selectively applying electrical energy to body tissue in order to ablate, contract, coagulate, or otherwise modify a target tissue or organ of a patients. An electrosurgical apparatus of the invention includes a shaft having a shaft distal end bearing an active electrode and a return electrode. At least one of the active electrode and the return electrode is moveable such that the shaft distal end can adopt a closed configuration or an open configuration. The apparatus can operate in an ablation mode or a sub-ablation mode. The closed configuration is adapted for clamping and coagulating a target tissue while the apparatus is operating in the sub-ablation mode, while the open configuration is adapted for ablating the target tissue via molecular dissociation of tissue components. A method of the present invention comprises clamping a target tissue or organ with an electrosurgical probe. A first high frequency voltage is applied between the active electrode and the return electrode to effect coagulation of the clamped tissue. Thereafter, a second high frequency voltage is applied to effect localized molecular dissociation of the coagulated tissue. The present invention allows the ablation or modification of the target tissue with minimal or no damage to surrounding, non-target tissue.

Power supply and methods for fluid delivery in electrosurgery

A system for applying high frequency electrical energy to a body structure within a patient where the system detects the presence of conductive fluid.

The surgical instruments preferably has a shaft with a distal end and a proximal end, an electrode terminal on or near the distal end, and a connector coupling the electrode terminal to the power supply. The conductive fluid sensor may comprise of an electric switch adapted to create an open circuit when in contact with conductive fluid. Alternatively, the conductive fluid sensor may be a resistor that changes resistance when in contact with conductive fluid. The sensor detects for conductive fluid such as body fluid or saline solution. For devices having an active and return electrode (i.e. bipolar), the sensor may detect for the presence of fluid between the two electrodes.

Methods for electrosurgical treatment of intervertebral discs

Systems, apparatus and methods for ablation, resection, aspiration, collagen shrinkage and/or hemostasis of tissue and other body structures in open and endoscopic spine surgery. In particular, the present invention includes a channeling technique in which small holes or channels are formed within spinal discs, 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 and for reducing the volume of the disc to relieve pressure on the surrounding nerves. High frequency voltage is applied between one or more active electrode(s) and one or more return electrode(s) to volumetrically remove or ablate at least a portion of the disc tissue, and the active electrode(s) are advanced through the space left by the ablated tissue to form a channel, hole, divot or other space in the disc tissue. In addition, the high frequency voltage effects a controlled depth of thermal heating of the tissue surrounding the hole to thermally damage or create a lesion within the tissue surrounding the hole to debulk and/or stiffen the disc structure, thereby relieving neck or back pain.

Systems and methods for electrosurgical tissue treatment

Systems and methods are provided for removal (ablation) or modification of soft tissue with high frequency voltage through a capacitive charge process. Specifically, one of the conductors of a capacitor device maybe positioned adjacent to, or in the region of, a body structure. The other conductor is spaced, and electrically insulated from, the first conductor. A high frequency voltage is applied across the conductors to create a potential difference that results in a charge on the conductors and creates an electric field therebetween. High frequency alternating current flows between the conductors to a degree dependent on the capacitance and the current frequency. The charge on the first conductor is sufficient to modify the adjacent tissue. In some variations the charge is sufficient to heat the tissue for tissue coagulation or tissue shrinkage (i.e., collagen contraction). In other variations, the charge is sufficient to ablate or volumetrically remove the tissue.

System and methods for electrosurgical tissue treatment in the presence of electrically conductive fluid

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.
