摘要： Systems and methods for discriminating between various gases, e.g., argon and helium, for enhanced safety of medical devices are provided. The present disclosure may take the form of a dedicated-use embodiment where a specific gas, helium for example, is expected, and an enabling or "Go" signal is issued when that gas is detected, or an inhibitory or "No-Go" signal when a gas is present that is not identified as helium. Alternately, a control line or input command can be used to select between helium and argon as the expected gas and then issue the appropriate "Go/No-Go" signal, depending on which gas is identified.

摘要： The present disclosure relates to devices, systems and methods for evaluating the success of a treatment applied to tissue in a patient, such as a radio frequency ablative treatment used to neuromodulate nerves associated with the renal artery. A system monitors parameters or values generated during the course of a treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of the likelihood that a completed treatment was technically successful. In other embodiments, parameters or values generated during the course of an incomplete treatment (such as due to high temperature or high impedance conditions) may be evaluated to provide additional instructions or feedback to an operator.

摘要： A multi-electrode ablation system (100) is described that includes a power supply configured to be coupled to a plurality of electrodes and a controller coupled to the power supply. The controller is configured to determine a thermal gain of each electrode of the plurality of electrodes. For each electrode of the plurality of electrodes, the controller sets a power limit based at least in part on said electrode's determined thermal gain. The power limit establishes a maximum power that may be dissipated through said electrode.

摘要： A grasping treatment unit includes a first jaw, and a second jaw openable and closable relative to the first jaw. In the first jaw, a heating wire continues without branching from a first extending end to a second extending end, and heat is generated over an entire length from the first extending end to the second extending end when the electric current flows through the heating wire. In a heating portion, a calorific value per unit area is higher in a distal portion than in a proximal portion in the first jaw when the heat is generated from the heating wire. On a treatment surface of the first jaw, an amount of heat transfer from the heating portion is greater in the distal portion than in the proximal portion.

摘要： The present disclosure provides for a device and methods of use to endoluminally ablate and/or occlude a body vessel using a current to perform resistive heating. The device includes a resistive coil having thermistor properties where the resistance of the coil changes as a function of temperature. A control unit will detect the voltage, current, and resistance in the coil during the heating of the coil to determine the temperature of the coil. As occlusion occurs and the cooling effect of blood flow decreases, less power will be required to maintain the coil at a desired temperature. Detecting a large decrease in required power will indicate to the control unit that the body vessel has become occluded.

摘要： The preferred embodiment provides apparatus (10) for ablating a vessel (80) by generating heat within a vessel to cause blood clotting to occlude the vessel. The apparatus includes an electrically resistive element (30) at the distal end (20) of the apparatus (10), the resistive element (30) being uncoated and therefore in bare form. An alternating current supply (24) feeds electrical current through the resistive element (30) to cause heating of the element (30) and surrounding blood or tissue. The alternating current power supply (24) preferably is balanced about a centre point so as to create a net sum of alternating pulses of zero. It has been found that the supply of alternating current to the resistive element (30) reduces or eliminates corrosion of the resistive element (30) in blood as the resistive element (30) is heated. Use of conductive coatings for a sacrificial anode can be avoided.
