摘要： 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.

摘要： 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.

摘要： In various embodiments, surgical devices and methods are provided. One such surgical device includes a ferromagnetic heater assembly. The ferromagnetic heater assembly includes an electrical conductor, a ferromagnetic heater, and an encapsulant. The electrical conductor has a first leg, a second leg, and a bend between the first and second legs. The bend is located at a distal tip of the electrical conductor, and the first and second legs are spaced apart from one another between the distal end and a proximal end of the electrical conductor. The ferromagnetic heater is disposed on the first leg of the electrical conductor. The encapsulant at least partially surrounds the ferromagnetic heater and a portion of the second leg opposite the ferromagnetic heater, and a surface of the ferromagnetic heater is at least partially exposed by the encapsulant.

摘要： 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.

摘要： 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.

摘要： A sealing and/or cutting instrument having a thermally active surface or element which may be used to seal and then cut tissue, ducts, vessels, etc., apart. The instrument may include a thermally active surface or element comprised of a conductor covered with a ferromagnetic material. The instrument may contact tissue with one or more surfaces comprised of a non-stick material. A sensor in communication with the instrument may be used to monitor a therapeutic procedure and signal when sealing and/or cutting of a tissue is complete.

摘要： 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.
