  • Patent number: 10413188
    Abstract: A method is described to enhance the ability to evaluate the depth of a tissue component or a lesion having optical properties different from a surrounding tissue using time resolved optical methods. This invention may be particularly suitable for the evaluation of lesion depth during RF ablation (irreversible tissue modification/damage) using specially designed devises (catheters) that deliver heat in a localized region for therapeutic reasons. The technique allows for increased ability to evaluate the depth of the ablated lesion or detect the presence of other processes such as micro-bubble formation and coagulation with higher sensitivity compared to that offered by steady state spectroscopy. The method can be used for in-vivo, real-time monitoring during tissue ablation or other procedures where information on the depth of a lesion or tissue is needed. Exemplary uses are found in tissue ablation, tissue thermal damage, lesion and tissue depth assessment in medical applications.

  • Patent number: 10278614
    Abstract: A method of detecting whether a localization element is within or outside of an introducer sheath generally includes obtaining a localization signal from the localization element and detecting the state of the localization element relative to the sheath based upon the quadrature component of the localization signal. A baseline quadrature component is typically established with the localization element outside of the sheath. When the quadrature component deviates from this baseline value, it is indicative of the localization element being within the sheath. Conversely, when the quadrature component remains relatively close to the baseline value, it is indicative of the localization element being outside of the sheath. In an electrophysiology study, the state information can be used to take corrective action with respect to the data being collected.

  • Patent number: 10278588
    Abstract: A system comprises a catheter and an electromagnetic sensor assembly supported at a distal end of the catheter. The electromagnetic sensor assembly includes a magnetic strut spirally extended away from the distal end of the catheter around an open area distal of the catheter. The system also comprises an imaging element supported at a distal end of the catheter inside the open area. The imaging element acquires an image of the tissue surface region. The system also comprises a processor that receives a position of the electromagnetic sensor assembly and the tissue surface image. The processor maps the position of the electromagnetic sensor assembly and tissue surface image together. The system also comprises a barrier reconfigurable from a low-profile shape to an expanded deployment shape projecting from a distal end of the catheter. The electromagnetic sensor assembly is spirally configured over the barrier.

  • Patent number: 10264987
    Abstract: An apparatus for detection of ANEA comprising an introducer having at least one lumen. The introducer is introduced into brain tissue through an opening in the skull. A reference electrode is positioned at an introducer distal portion. A plurality of electrode members are advanceable within the at least one lumen with each member having an insulated portion and an exposed distal portion. The members have a non-deployed state in the introducer and a deployed state when outwardly advanced out of the introducer. In the deployed state, the members are substantially orthogonal to each other with the exposed distal portions defining a detection volume capable of determining an electric field vector produced by the ANEA and the direction of foci of the ANEA.

  • Patent number: 10244955
    Abstract: Systems and methods for noncontact ablation of tissues or materials in/on the body using a luminal catheter and a catheter inserted into the lumen. In one embodiment, the luminal catheter is an ablation catheter and the other catheter is a recording/measurement/positioning catheter. The luminal catheter incorporates a noncontact ablation element such as an ultrasonic transducer. The luminal catheter can be inserted through the skin and into the body (e.g., into the heart) and the recording/measurement/positioning catheter can be inserted into the lumen so that the ablation and recording/measurement/positioning catheters are simultaneously positioned to record/measure the electrical activity of the target tissue and ablate the target tissue without causing the trauma that results from the introduction of additional catheters. Either of the ablation and recording/measurement/positioning catheters can be steerable, and either may incorporate recording/measurement electrodes.

  • Patent number: 10238863
    Abstract: Percutaneously advanced, distally into tissue of a subject, are (i) an implant, including an electrode and an anchor, and (ii) a tool. The tool includes an implant-storage member that houses the implant, and shaped to define a distal opening, and (b) a delivery manipulator, configured to facilitate bidirectional movement of the implant through the distal opening. Subsequently, the anchor and the electrode are exposed from the implant-storage member by withdrawing the implant-storage member proximally with respect to the implant. While the anchor and the electrode remain exposed from the implant-storage member, the implant is repositioned within the tissue by moving the implant, the implant-storage member, and the delivery manipulator with respect to the tissue. Subsequently, the tool is decoupled from the implant, and the tool is removed from the subject. Other embodiments are also described.

  • Patent number: 10231778
    Abstract: Techniques are disclosed for contemporaneously assessing the success of a renal denervation procedure. One or more characteristics of a patient's heart, such as atrioventricular (AV) interval, PR interval and/or heart rate are monitored during an ablation procedure. A change in the heart characteristic detected during the ablation may indicate successful denervation. Accordingly, successive new locations may be targeted for ablation until a change is detected.
