Patent number: 10322287Abstract: Provided is a portable controller and associated method that provides a patient or caregiver the ability to recharge and alter the parameters of an implanted medical device, while allowing the patient substantially unobstructed mobility. To enable mobility, the controller may be worn on a belt or clothing. The controller also allows the patient to turn device stimulation on and off, check battery status, and to vary stimulation parameters within ranges that may be predefined and programmed by a clinician. The controller communicates with the medical device to retrieve information and make parameter adjustments using wireless telemetry, and it can send and receive information from several feet away from the implanted medical device. Charging of a battery contained in the implanted medical device is achieved via an inductive radio frequency link using a charge coil placed in close proximity to the medical device.Type: GrantFiled: October 31, 2016Date of Patent: June 18, 2019Assignee: Medtronic Urinary Solutions, Inc.Inventors: Robert B. Strother, James E. Barber, Joseph J. Mrva, Christopher A. Thierfelder, Maria E. Bennett, Geoffrey B. Thrope, Danny R. Pack, Stuart F. Rubin

Patent number: 10278762Abstract: A system and method for wirelessly powering an electrosurgical device using a generator to generate a radio frequency (RF) energy field. A switch on the electrosurgical device sends a wireless signal to the generator, where the generator allows a current to pass through an inductive coil to generate the RF energy field. The RF energy field induces a current to flow across an inductive coil within the electrosurgical device. The current flow is then processed through a RF conditioning circuit and outputted to the end effector assembly of the device.Type: GrantFiled: August 11, 2014Date of Patent: May 7, 2019Assignee: COVIDIEN LPInventors: Tony Moua, Jason L. Craig

Patent number: 10238864Abstract: In an interventional medical system, a delivery catheter for deploying a medical device of the system has a tethering assembly that includes a tether line, a grip member, and a release member, wherein the tether line extends through a longitudinal lumen of a base of the release member and is coupled to a base of the grip member, and the release member has legs extending though apertures formed through the base of the grip member. The device may be tethered to the catheter such that a proximal end of the device is held within a cavity defined by a plurality of elastic fingers of the grip member that extend distally from the base thereof; and the device may be deployed from the catheter by moving the legs of the release member within the grip member cavity to push the proximal end of the device out from the cavity.Type: GrantFiled: July 29, 2016Date of Patent: March 26, 2019Assignee: Medtronic, Inc.Inventors: Thomas A. Anderson, Vladimir Grubac

Patent number: 10143850Abstract: Systems and methods are disclosed to stimulate tissue to treat medical conditions involving tissues such as the bone, spine, stomach, nerves, brain and the cochlea. The disclosed invention uses electrical stimulation of the tissue, where vibrational (or acoustic) energy from a source is received by an implanted device and converted to electrical energy and the converted electrical energy is used by implanted electrodes to stimulate the pre-determined tissue sites. The vibrational energy is generated by a controller-transmitter, which could be either implanted or located externally. The vibrational energy is received by a receiver-stimulator, which could be located at or close to the stimulation site.Type: GrantFiled: August 29, 2016Date of Patent: December 4, 2018Assignee: EBR Systems, Inc.Inventors: Mark W.
