  • Patent number: 10076378
    Abstract: A matrix router with frequency switching is provided having an energy source electrically connected to a plurality of interface ports. A switching device is provided between the energy source and the plurality of switches. One of the plurality of interface ports includes a paired electrode interface port for the connection of a paired electrode device thereto. The paired electrode device has a first pair of opposed electrodes and a second pair of opposed electrodes for clamping on tissue. When the paired electrode device is operably connected to the paired electrode interface port and actuated, the switching device alternates energy such as bipolar RF from the first pair of opposed electrodes to the second pair of opposed electrodes.

  • Publication number: 20100152728
    Abstract: A method and apparatus are provided for assessing the degree of electrical signal blockage, or transmurality, of a line of ablation in which at least a first electrode adapted to deliver an electrical impulse is located on the first or one side of a line of ablation; and at least a second and a third electrode adapted to detect an electrical impulse are located on the second side of the line of ablation generally opposite to the first electrode. Each electrode may also be made up of more than one electrode, such as an electrode pair, to better assure reliability and tissue contact. Once the electrodes are located in contact with the tissue in question, an electrical impulse is delivered to the target tissue by the first electrode and detected by the second and third electrodes.

  • Patent number: 7473250
    Abstract: An ultrasound medical system includes an interstitial end effector. The interstitial end effector is interstitially insertable into patient tissue, includes at least one medical-treatment ultrasound transducer, and includes at least one end-effector-tissue-track ablation device. One method for ultrasonically treating a lesion in a patient includes the steps of obtaining the interstitial end effector and inserting it into the patient creating a tissue track which is surrounded by patient tissue and which ends at the distal end of the inserted interstitial end effector. Other steps include ultrasonically ablating the lesion using the at-least-one medical-treatment ultrasound transducer, using the at-least-one end-effector-tissue-track ablation device to ablate the patient tissue surrounding the tissue track along substantially the entire tissue track, and withdrawing the end effector from the patient.
