Patent number: 9554853Abstract: An apparatus and method for use in performing ablation of organs and other tissues includes a radio frequency generator which provides a radio frequency signal to ablation electrodes. The power level of the radio frequency signal is determined based on the subject area of ablation. The radio frequency signal is coupled with the ablation electrodes through a transformation circuit. The transformation circuit includes a high impedance transformation circuit and a low impedance transformation circuit. The high or low impedance transformation circuit is selected based on the impedance of the ablation electrodes in contact with the subject tissue. Vacuum level, impedance level, resistance level, and time are measured during ablation. If these parameters exceed determinable limits the ablation procedure is terminated.Type: GrantFiled: October 4, 2013Date of Patent: January 31, 2017Assignee: Hologic, Inc.Inventors: Bruno Strul, Csaba Truckai, Russel M. Sampson, Mark L. Kane

Patent number: 8523856Abstract: A method and system for achieving hemostasis (the stoppage of bleeding) is described. RF (radio frequency) energy is used to ablate the surface of tissue to stop bleeding. The depth of destruction of the tissue can be controlled so as to desiccate and coagulate the tissue. In one implementation, an electrode carrier including bipolar electrodes is applied to the tissue, and RF energy transmitted through the bipolar electrodes to ablate the tissue. A layer of desiccated tissue can be created as well as coagulation of the tissue to achieve hemostasis.Type: GrantFiled: September 5, 2012Date of Patent: September 3, 2013Assignee: Cytyc CorporationInventors: Russel M. Sampson, Eugene V. Skalnyi

Patent number: 8486060Abstract: A method for tissue ablation is described. An RF applicator including an electrode carrier with one or more bipolar electrodes thereon is positioned at a target tissue site for tissue ablation. A current at an initial current level is passed through the one or more bipolar electrodes to the target tissue site to apply an initial power density to destroy tissue for an initial time period. A vacuum source in fluid communication with the RF applicator is employed to remove moisture generated during ablation away from the target tissue site. After the initial time period, the power density is ramped up by increasing the current passed through the one or more bipolar electrodes to the target tissue site for a second time period.Type: GrantFiled: September 18, 2006Date of Patent: July 16, 2013Assignee: Cytyc CorporationInventors: Robert Kotmel, Russel M. Sampson, Scott Dennis Taylor

Publication number: 20100228245Abstract: A medical device and procedure is described for occluding a fallopian tube. A tubal occlusion device is inserted into a uterine cavity. The device includes an RF applicator head including an electrode carrier with one or more bipolar electrodes thereon. During insertion, the RF applicator head can be in a closed position. The RF applicator head is positioned at a tubal ostium of a fallopian tube, such that a distal tip of the RF applicator head advances into the tubal ostium. The RF applicator head is deployed into an open position such that the RF applicator head approximates the shape of the uterine cavity in a region of the tubal ostium. Current is passed through the one or more bipolar electrodes to the tubal ostium to destroy tissue to a known depth, which precipitates a healing response in surrounding tissue that over time scars and occludes the fallopian tube.Type: ApplicationFiled: May 21, 2010Publication date: September 9, 2010Inventors: Russel M.

Publication number: 20100217250Abstract: A body passage having an interior wall with a lining is occluded by introducing a thermal delivery catheter to the passage. The thermal delivery catheter has a thermal transfer region which can deliver both a coagulative tissue necrosis energy dosage and a thermally fixing energy dosage. The coagulative necrosis dosage will result in scar tissue formation, while the thermally fixing tissue dosage will prevent regrowth of the tissue lining from neighboring untreated tissue regions which could compromise the integrity of the occlusion which is formed.Type: ApplicationFiled: February 24, 2010Publication date: August 26, 2010Applicant: Sierra Surgical TechnologiesInventor: Russel M.
