Patent number: 9623237Abstract: Various examples are directed to systems and methods comprising receiving a control signal at a control circuit of a surgical device. The control circuit may comprise a first circuit portion coupled to at least one switch operable between an open state and a closed state. The first circuit portion may be configured to communicate with a surgical generator over a conductor pair to receive the control signal and may comprise at least one resistor coupled to the at least one switch. Methods may also comprise determining the state of the at least one switch based on the value of the resistor.Type: GrantFiled: September 28, 2015Date of Patent: April 18, 2017Assignee: Ethicon Endo-Surgery, LLCInventors: Douglas J. Turner, Jeffrey L. Aldridge, Vincent P. Battaglia, Jr.

Patent number: 9623238Abstract: The present specification discloses devices and methodologies for the treatment of achalasia. Individuals with achalasia are treated by implanting a stimulation device within the patient's lower esophageal sphincter and applying electrical stimulation to the patient's lower esophageal sphincter, in accordance with certain predefined protocols. The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow and have improved energy storage requirements.Type: GrantFiled: August 23, 2013Date of Patent: April 18, 2017Assignee: Endostim, Inc.Inventors: Virender K. Sharma, Shai Policker, Bevil Hogg

Patent number: 9623239Abstract: The present invention provides, among other things, apparatus and methods of use for treating a subject in need of assistance with breathing. In some embodiments the subject suffers from airflow obstruction. In some embodiments, the subject suffers from chronic obstructive pulmonary disease.Type: GrantFiled: September 18, 2015Date of Patent: April 18, 2017Assignee: Apellis Holdings, LLCInventors: Cedric Francois, Angus McLachlan

Patent number: 9623240Abstract: Devices, systems and methods are disclosed for treating bronchial constriction related to asthma, anaphylaxis, chronic obstructive pulmonary disease (COPD), exercise-induced bronchospasm and post-operative bronchospasm. The treatment comprises transmitting impulses of energy non-invasively to selected nerve fibers that activate neural pathways to reduce the release of acetycholine from airway-related vagal preganglionic neurons within the brain of the patient. The transmitted energy impulses, comprising magnetic and/or electrical energy, stimulate the selected nerve fibers to produce the bronchodilation.Type: GrantFiled: March 17, 2015Date of Patent: April 18, 2017Assignee: Electrocore, LLCInventors: Bruce J. Simon, Joseph P. Errico, John T. Raffle

Patent number: 9623242Abstract: A method of generating frequency-modulated pulse trains in a CI includes dividing data representing audio spanning frequency bands into a plurality of bins associated with each frequency band, each bin representing an energy level of the data within the frequency band within a period of time; associating each frequency band with a phase probability that starts at an initial phase probability value (PPV), resets to a minimum PPV after generating a pulse, and increases from the minimum PPV to a maximum PPV over a period of time; for each bin, assigning a power probability as a normalized intensity being a number between a minimum power probability and a maximum power probability representing the energy level of the bin, and generating a pulse in an electrode associated with the frequency band associated with the bin when a random number generated is less than the power probability divided by the phase probability.Type: GrantFiled: July 11, 2016Date of Patent: April 18, 2017Assignees: NORTHWESTERN UNIVERSITY, RESONANCE MEDICAL, LLCInventors: Claus-Peter Richter, Reagan Roberts

Patent number: 9623244Abstract: An electrical neuromodulation system configured for minimizing energy consumption of a neuromodulation device includes an external control device configured for receiving input from a user, the neuromodulation device in communication with the external control device, and control/processing circuitry. The control/processing circuitry is configured for automatically (a) adjusting a modulation parameter value (e.g., by a step size) to create a currently adjusted modulation parameter value that decreases the energy consumption of the neuromodulation device, (b) instructing the neuromodulation device to deliver electrical energy to at least one electrode in accordance with the currently adjusted modulation parameter value, (c) determining whether a manual parameter adjustment was made by the user in response to step (b), and (d) if the manual parameter adjustment was not made, deeming the currently adjusted modulation parameter value as a previously adjusted modulation parameter value and repeating steps (a)-(d).Type: GrantFiled: February 21, 2014Date of Patent: April 18, 2017Assignee: Boston Scientific Neuromodulation CorporationInventor: Sridhar Kothandaraman

Patent number: 9623245Abstract: A therapy program for peripheral nerve field stimulation (PNFS) may be selected based on user input indicating a desired therapeutic effect for a user-specified region in which a patient feels pain. In other examples, PNFS may be programmed based on input from a user selecting at least one region from among a plurality of regions in which the patient experiences pain. In addition, the PNFS may be programmed based on user input defining an aspect of PNFS for the selected region, such as a relative intensity of PNFS delivered to at least two selected regions, a balance of PNFS between at least two regions, a desired shift in PNFS from a first region to a second region, or an extent to which a first stimulation field within a first region overlaps with a second stimulation field in a second region.Type: GrantFiled: September 4, 2014Date of Patent: April 18, 2017Assignee: Medtronic, Inc.Inventors: Gary W. King, Steven M. Goetz, Andrew H. Houchins, Jeffrey T. Keacher, Jordan J. Greenberg
