Publication number: 20230130437Abstract: A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.Type: ApplicationFiled: November 7, 2022Publication date: April 27, 2023Applicant: Mederi RF, LLCInventors: Oleg Shikhman, William W. Rutan, Danny L. Stemple, Penny R. Smith, Gregory K. Thompson, Thomas L. McGilvary

Patent number: 11471214Abstract: A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to treat tissue to create lesions without ablating the tissue. The system includes a first treatment device having a plurality of electrodes. The electrodes are maintained in axial alignment and fixed radial spacing in retracted and extended positions. The device includes a basket having a plurality of arms. The arms are maintained in a fixed radial spacing in the collapsed position of the basket.Type: GrantFiled: July 13, 2019Date of Patent: October 18, 2022Assignee: MEDERI RF, LLCInventors: Oleg Shikhman, Ronald L. Green, Jeffrey Radziunas

Patent number: 10639090Abstract: A system for controlling a treatment device generates a graphical interface that visually prompts a user in a step-wise fashion to use the treatment device to perform a process of forming a pattern of lesions that extends both circumferentially and axially in different levels in a body region. The graphical interface displays for the user a visual record of the progress of the process from start to finish and guides the user so that so that individual lesions desired within a given level are all formed, and that a given level of lesions is not skipped.Type: GrantFiled: March 12, 2016Date of Patent: May 5, 2020Assignee: Mederi RF, LLCInventors: Oleg Shikhman, William W. Rutan

Patent number: 10292756Abstract: A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to treat tissue to create lesions without ablating the tissue. The system includes a device having flexible outer tube, an expandable basket having a plurality of arms movable from a collapsed position to an expanded position, a plurality of electrodes movable from a retracted position to an extended position to extend through the openings in the arms, and an advancer slidably disposed within the outer tube to move the electrodes. An elongated spacer is positioned within the outer tube, the spacer having a central lumen to receive the advancer and to maintain a central position of the advancer.Type: GrantFiled: May 26, 2017Date of Patent: May 21, 2019Assignee: Mederi RF, LLCInventors: Oleg Shikhman, Ronald L.
