Patent number: 9962564Abstract: A minimally invasive applicator device for treatment of intervertebral tissue containing at least one target nerve includes an insertion device having a proximal end and a distal end for insertion into the intervertebral tissue containing at least one target nerve, an ultrasound transducer device coupled to the distal end of the insertion device, and an external RF power generator electrically that provides power to the ultrasound transducer device. The ultrasound transducer device includes an array of a plurality of transducer crystals which are all aligned along a line defined by an axis enclosed by each of the plurality of transducer crystals disposed sequentially and longitudinally adjacent each other along the axis to form a customized flexible array along the applicator device. Ultrasound radiative output treatment outward from the axis of the transducer crystals allows for treatment of the intervertebral tissue containing at least one target nerve.Type: GrantFiled: August 31, 2015Date of Patent: May 8, 2018Assignee: ACCOUSTIC MEDSYSTEMS, INC.Inventors: Everette C. Burdette, Dana Deardorff

Publication number: 20150367147Abstract: An ultrasound device and method for the treatment of intervertebral disc tissue for remediation of back pain. An applicator comprises a catheter and/or needle with a distal tip including one or more ultrasound transducer crystals. The crystals produce high-powered ultrasound energy that is transmitted and absorbed in the disc tissue. The resulting temperature elevation of the disc tissue shrinks the collagen fibers in the surrounding tissue, and/or destroying small nerves that may have invaded and innervated the surrounding degenerated tissue, and can provide increased structural integrity and disc support for the fragmented nucleus pulposus to relieve pressure on the spinal nerves.Type: ApplicationFiled: August 31, 2015Publication date: December 24, 2015Applicant: Acoustic MedSystems, Inc.Inventors: Everette C. Burdette, Dana Deardorff

Publication number: 20150196743Abstract: An apparatus and method for shielding non-target tissues and organs during thermotherapy, brachytherapy or other treatment of a diseased target tissue. The apparatus includes a catheter shaft having input and output lumens and at least one inflatable balloon. A plurality of input lumens within the catheter shaft allows the passage of liquid or gas through an input port and into the interior of the balloon thereby inflating the balloon. The gas or liquid can then be cycled through the inflated balloon through an output port and output lumen and out of the catheter shaft. Temperature sensors or other sensors may be attached to the balloon or catheter to monitor temperature or other conditions at the treatment site. The catheter is positioned between the target tissue or organ and sensitive non-target tissues in proximity to the target tissue and inflated causing a physical separation of tissues as well as a physical shield.Type: ApplicationFiled: January 14, 2015Publication date: July 16, 2015Applicants: ACOUSTIC MEDSYSTEMS, INC., THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Chris J. Diederich, Dana Deardorff

Publication number: 20150011305Abstract: Systems, methods, and software are disclosed herein for charitable gaming. Users can play a game and donate money or value to non-profit charitable organizations through online gaming, where the players in a game compete to determine how portions of the value from the game's prize pool will be allocated to one or more charity organizations.Type: ApplicationFiled: June 30, 2014Publication date: January 8, 2015Inventor: Dana Deardorff

Patent number: 8790281Abstract: A high-power ultrasound heating applicator for minimally-invasive thermal treatment of uterine fibroids or myomas. High-intensity interstitial ultrasound, applied with minimally-invasive laparoscopic or hysteroscopic procedures, is used to effectively treat fibroids within the myometrium in lieu of major surgery. The applicators are configured with high-power capabilities and thermal penetration to treat large volumes of fibroid tissue (>70 cm3) in short treatment times (3-20 minutes), while maintaining three-dimensional control of energy delivery to thermally destroy the target volume.Type: GrantFiled: April 20, 2007Date of Patent: July 29, 2014Assignees: The Regents of the University of California, Acoustic Medsystems, Inc.Inventors: Chris J. Diederich, Will Nau, Alison Jacoby, Dana Deardorff, Everette C. Burdette

Publication number: 20110315147Abstract: Various embodiments of a tracheal tube having a multifunctional lumen disposed in a tracheal tube wall are provided. Provided tracheal tubes include a ventilation lumen, through which bidirectional airflow may be established to and from a patient during operation, as well as a multifunctional lumen adapted to receive a variety of interchangeable medical devices. Embodiments of the provided tracheal tubes may provide for insertion or removal of a medical device from the multifunctional lumen without extubation of the tracheal tube from a patient.Type: ApplicationFiled: June 29, 2010Publication date: December 29, 2011Applicant: Nellcor Puritan Bennett LLCInventors: Lockett E. Wood, Dawn Bitz, Dana Deardorff

Publication number: 20110073115Abstract: According to various embodiments, a tracheal tube may include a cuff assembly that relies on mechanical pressure rather than inflation pressure to form a seal against a patient's trachea. Such cuff assemblies may include cone or umbrella-shaped structures that may form seals at substantially lower pressures than traditional inflation cuffs. One or more of such cuff assemblies may be used instead of or in addition to an inflation cuff to provide an improved seal.Type: ApplicationFiled: September 30, 2009Publication date: March 31, 2011Applicant: Nellcor Puritan Bennett LLCInventors: Lockett E. Wood, Sarah Hayman, Susan Roweton, Lise-Helene Moloney, Dana Deardorff
