Patent number: 11266459Abstract: 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.Type: GrantFiled: November 7, 2016Date of Patent: March 8, 2022Assignee: Domain Surgical, Inc.Inventors: Kim H. Manwaring, David J. McNally, Philip Eggers, Preston Manwaring, Mark Stringham, Kent Beck, David Wright, Josh Middel

Patent number: 11123127Abstract: A thermal surgical instrument having a system to control the delivery of power from an energy source to an active element located on a tip. The system for controlling delivery to the tip may include a control algorithm which uses one 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.Type: GrantFiled: December 19, 2016Date of Patent: September 21, 2021Assignee: Domain Surgical, Inc.Inventors: Scott Denis, Preston Manwaring, Phil Eggers, Kim Manwaring

Publication number: 20200129222Abstract: 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.Type: ApplicationFiled: October 25, 2019Publication date: April 30, 2020Inventors: Mark Stringham, Preston Manwaring, Philip Eggers, Scott Denis

Publication number: 20190307357Abstract: 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.Type: ApplicationFiled: October 10, 2018Publication date: October 10, 2019Inventors: Kim Manwaring, Preston Manwaring

Patent number: 9149321Abstract: A cooling system for a surgical handpiece may provide fluid flow to the surgical tip and to the internal electronic components to prevent temperatures that may damage or make the patient or surgeon uncomfortable. Tip directed gas further controls the tip-tissue interface by displacing blood or serum from the incision point, increasing precision and diminishing coagulum build-up. In the alternative, cooling fluid may be used to quench tissue being treated.Type: GrantFiled: November 26, 2014Date of Patent: October 6, 2015Assignee: Domain Surgical, Inc.Inventors: Mark Stringham, Preston Manwaring, Kim Manwaring, Philip Eggers

Publication number: 20150173822Abstract: An impedance matching circuit may be used to adjust for manufacturing and design tolerances in a surgical instrument. The matching circuit may match the load of a thermal element with the impedance of a power source used to deliver electrical energy to the surgical instrument. The matching circuit may include capacitors, inductors, coaxial cables, varactors, transformers, resistors, and/or combinations thereof. The matching circuit may also comprise a circuit board or flex board layers which may be modified to adjust the impedance of the load.Type: ApplicationFiled: November 24, 2014Publication date: June 25, 2015Inventors: Preston Manwaring, Kim Manwaring, Mark Stringham, Phil Eggers
