Publication number: 20160030102Abstract: 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.Type: ApplicationFiled: July 11, 2015Publication date: February 4, 2016Applicant: Domain Surgical, Inc.Inventors: Kim Manwaring, David McNally

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

Patent number: 9131977Abstract: 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.Type: GrantFiled: April 6, 2012Date of Patent: September 15, 2015Assignee: Domain Surgical, Inc.Inventors: Kim Manwaring, Phillip Eggers, Mark Stringham, Paul Hammond, David J.

Patent number: 9078655Abstract: 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.Type: GrantFiled: September 1, 2011Date of Patent: July 14, 2015Assignee: Domain Surgical, Inc.Inventors: Kim Manwaring, David McNally

Patent number: 8915909Abstract: 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: GrantFiled: April 7, 2012Date of Patent: December 23, 2014Assignee: Domain Surgical, Inc.Inventors: Preston Manwaring, Kim Manwaring, Mark Stringham, Phil Eggers

Patent number: 8858544Abstract: A surgical instrument guide for facilitating treatment of a target tissue is provided. The surgical instrument guide may be placed between two groups of tissue such that a first group of tissue is cut and a second group of tissue is protected from being cut. The surgical instrument guide may lift tissue and slide tissue along a surface so that a target tissue may be cut to a desired depth more easily during a surgical procedure. The surgical instrument guide may be releasably attachable to a surgical instrument or integrally formed therewith.Type: GrantFiled: May 15, 2012Date of Patent: October 14, 2014Assignee: Domain Surgical, Inc.Inventors: David J. McNally, Kim H. Manwaring, Mark Stringham, Mark Shafer

Publication number: 20140074082Abstract: 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.Type: ApplicationFiled: November 15, 2013Publication date: March 13, 2014Applicant: Domain Surgical, Inc.Inventors: Scott Denis, Preston Manwaring, Phil Eggers, Kim Manwaring
