摘要： An instrument test arrangement is specified, which is preferably equipped for medical instruments for argon plasma coagulation. The instrument test arrangement comprises an electrode arrangement, comprising at least one test electrode. In a preferred embodiment, a test electrode is thereby connected to two neutral conductors of a neutral conductor cable or device, wherein the neutral conductors are insulated from one another, and wherein the first coupling impedance between the test electrode and the first neutral conductor and the second coupling impedance between the test electrode and the second neutral conductor are equal or at most slightly different, so that a split circuit, which is assigned to a neutral electrode arrangement, does not trigger due to the strike of a test spark or arc.

摘要： A tissue treatment device includes a circuit driver, an electrode, and a plasma arc focusing element, all disposed within a housing. The circuit driver generates a plasma arc source signal. The electrode generates a plasma stream in response to the plasma arc source signal. The plasma arc focusing element focuses the plasma stream to pass through an outlet hole of the housing and onto a target spot on a target tissue of a treatment subject for heat treatment of the target tissue. In some embodiments, the circuit driver controls a temperature increase of the target tissue by modulating a fundamental frequency, power level, pulsing frequency, and/or pulsing duty cycle of the plasma arc source signal.

摘要： A catheter treatment apparatus comprises an elongate tubular member and an expandable support. The expandable support comprises a radioactive substance to treat cancerous tissue and is configured to expand from a narrow profile for insertion to a wide profile to engage and treat tissue remaining after resection. The expandable support can be sized to fit within a volume of removed tissue to place the radioactive substance in proximity to the capsule and remaining tissue, to spare the capsule and proximate nerves and vessels to treat tissue in proximity to the capsule. The elongate tubular member may comprise a channel such as a lumen to pass a bodily fluid such as urine when the expandable support engages the tissue to treat the patient for a plurality of days. The treatment apparatus can be used to resect and diagnose tissue concurrently. Based on the diagnosis, targeted segmental treatment may be given.

摘要： This invention relates to high-frequency ablation of tissue in the body using a cooled high-frequency electrode connected to a high frequency generator including a computer graphic control system and an automatic controller for control the signal output from the generator, and adapted to display on a real time graphic display a measured parameter related to the ablation process and visually monitor the variation of the parameter of the signal output that is controlled by the controller during the ablation process. In one example, one or more measured parameters are displayed simultaneously to visually interpret the relation of their variation and values. In one example, the displayed one or more parameters can be taken from the list of measured voltage, current, power, impedance, electrode temperature, and tissue temperature related to the ablation process. The graphic display gives the clinician an instantaneous and intuitive feeling for the dynamics and stability of the ablation process for safety and control. This invention relates to monitoring and controlling multiple ground pads to optimally carry return currents during high-frequency tissue ablation, and to prevent of ground-pad skin burns. This invention relates to the use of ultrasound imaging intraoperatively during a tissue ablation procedure. This invention relates to the use of nerve stimulation and blocking during a tissue ablation procedure.
