  • Patent number: 11324550
    Abstract: A system and method for assessing effective delivery of ablation therapy to a tissue in a body is provided. A three-dimensional anatomical map of the tissue is generated and displayed with the map defining a corresponding volume. An index is generated corresponding to a location within the volume with the index indicative of a state of ablation therapy at the location. The index may be derived from one or more factors such as the duration an ablation electrode is present at the location, the amount of energy provided, the degree of electrical coupling between an ablation electrode and the tissue at the location and temperature. A visual characteristic (e.g., color intensity) of a portion of the anatomical map corresponding to the location is then altered responsive to the index.

    Abstract: A system includes signal acquisition circuitry, an oscillator circuit, and a processor. The signal acquisition circuitry is configured to receive from an intra-cardiac probe multiple intra-cardiac signals acquired by multiple electrodes of the probe, and to further receive a common ground signal for the multiple intra-cardiac signals. The signal acquisition circuitry is further configured to digitize the intra-cardiac signals relative to the common ground signal so as to produce multiple digital signals. The oscillator circuit is configured to generate an Alternating Current (AC) signal and to apply the AC signal to the common ground signal provided to the signal acquisition circuitry. The processor is configured to detect the AC signal in the multiple digital signals, and to assess, based on the detected AC signal, respective qualities of physical contact between the electrodes and cardiac tissue.

    Abstract: A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having a plurality of sharp edges is formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high RPMs to cut bone and other hard tissue. An electrode is carried in a distal portion of ceramic cutting member for RF ablation of tissue when the sleeve and cutting member are is a stationary position. In methods of use, (i) the ceramic member can be engaged against bone and then rotated at high speed to cut bone tissue, and (ii) the ceramic member can be held in a stationary (non-rotating) position to engage tissue and RF energy can be delivered to the electrode to create a plasma that ablates tissue.
