  • Patent number: 10639089
    Abstract: An electrical conductor, such as a wire or catheter, which is coated circumferentially with a ferromagnetic material in a selected region, is fed from a high frequency alternating current source. The ferromagnetic material has a quick response in heating and cooling to the controllable power delivery. The ferromagnetic material can be used for separating tissue, coagulation, tissue destruction or achieving other desired tissue effects in numerous surgical procedures.

  • Patent number: 10441342
    Abstract: Thermal, electrosurgical and mechanical modalities may be combined in a surgical tool. Potentially damaging effects in a first modality may be minimized by using a secondary modality. In one example, thermal hemostasis may thus help electrosurgical applications avoid the adverse tissue effects associated with hemostatic monopolar electrosurgical waveforms while retaining the benefits of using monopolar incising waveforms.

  • Publication number: 20190307357
    Abstract: Electrical impedance monitoring of a tissue or an organ for perfusion or viability has been limited by sensitivity and baseline shifts. An apparatus and method are described which improve sensitivity by making the intervening tissue between pairs of electrodes a determinant component of electrical resonance. Such sensitivity further enhances detection of the pulsatile component of blood flow within a tissue. Baseline shift can be monitored and compensated due to resonance shift. The method is adaptable to sufficiency of perfusion monitoring or viability, imaging by 2-dimensional or 3-dimensional electrical impedance tomography, monitoring of tissue ablation by thermal or chemical methods, and thermoplasty of tissues to alter their form and functionality.

  • Patent number: 10405914
    Abstract: A power source delivers oscillating electrical energy to an electrical conductor, such as a wire or catheter, which is coated circumferentially with a ferromagnetic material in a selected region. With high frequency electrical energy, the ferromagnetic material has a quick response in heating and cooling adjustable by the controllable power delivery. The ferromagnetic material can be used for separating tissue, coagulation, tissue destruction or achieving other desired tissue effects in numerous surgical procedures.

  • Patent number: 10213247
    Abstract: A thermal surgical instrument comprising a conductor having a ferromagnetic material in electrical communication with the conductor, such that passage of electrical energy through the conductor causes substantially uniform heating of the ferromagnetic material sufficient to produce a desired therapeutic tissue effect is provided. The conductor may be shaped to facilitate resection of tissue from a patient and include a support to provide increase rigidity to the loop so that the conductor better resists bending during use. The ferromagnetic material quickly heats and cools in response to a controllable power delivery source. The thermal surgical instrument can be used for substantially simultaneously resecting tissue with hemostasis.

  • Patent number: 10149712
    Abstract: A thermal surgical tool comprising a conductor having a ferromagnetic material attached thereto is provided. The conductor may include a support of sufficiently high Young's modulus to resist bending when the surgical tool is being used to treat tissue. One or more intervening layers may be disposed between the support and the ferromagnetic material. Each of the intervening layers may be selected for a property that facilitates construction of the surgical tool and/or enhances a functionality of the surgical tool. The thermal surgical tool can be used for separating tissue, coagulation, tissue destruction or achieving other desired tissue effects in numerous surgical procedures.

  • Publication number: 20170196617
    Abstract: A thermal surgical instrument having a system to control the delivery of power from an energy source to active element located on a tip. The system for controlling delivery to the tip may include a control algorithm which uses on or more measurements, such as tip current, SWR, and rapid changes in reflected power, to manage power without affecting cutting efficacy, and in a manner that may be imperceptible by a surgeon. The system may utilize a state machine to determine the current environment in which the tip may be in. Power delivered to the tip may be selectively managed according to a fixed power index or a repeatedly executed power profile.

  • Patent number: 9265556
    Abstract: Thermally adjustable surgical tools include a conductor and a ferromagnetic material. The ferromagnetic material may be quickly heated when subjected to high frequency alternating current through the conductor. The ferromagnetic material may also cool rapidly because of its relatively low mass and the small thermal mass of the conductor. The thermally adjustable surgical tools may be used to sculpt, melt, break and/or remove biological material. The thermally adjustable surgical tools may also include balloon catheters which can heat fluid to thereby treat biological material.
