With the balloon (8) located in the sphincter (2) as the balloon (8) is being inflated, the microprocessor (8) computes the minimum diameter value of the balloon (8) from signals read from the sensing electrodes (12) each time the cumulative volume of the liquid saline solution in the balloon (8) increases by a predefined unit volume.Type: ApplicationFiled: May 20, 2016Publication date: June 7, 2018Applicant: Flip Technologies LimitedInventor: John O'DEA

Publication number: 20180153474Abstract: An EEG headpiece includes an array of electrode pins, each electrode pin extending between a proximal end, formed by a proximal end face, and a distal end and including a conducting electrode and a thermoplastic material. The thermoplastic material is arranged at least around a periphery of the electrode pin or is pressable from a hollow space to the periphery. Each electrode pin is equipped for the transmission of energy, especially mechanical vibration energy, from the proximal end face to the thermoplastic material to liquefy at least portions of the thermoplastic material from a solid state to a flowable state, whereby the thermoplastic material is capable of flowing into structures of a tissue portion surrounding the periphery and of forming, after re-solidification of the thermoplastic material, an anchoring of the electrode pin in the tissue portion.Type: ApplicationFiled: October 2, 2015Publication date: June 7, 2018Inventors: Marcel Aeschlimann, Jörg Mayer, Mario Weiss, Aymeric Niederhauser

Publication number: 20180153476Abstract: This document discusses, among other things, systems and methods for detecting stroke. A system may comprise a sensor circuit for sensing a physiological signal, and a second sensor to detect a physical state change. The physical state change may include a transition in physical activity, posture, or sleep state. A stroke risk circuit may detect, from the sensed physiological signal, a signal indicative of blood pressure surge (BPS) in response to one or more physical state changes. The system may generate a stroke risk indicator indicating a risk of developing an impending stroke event using the detected BPS. The system includes an output unit that outputs the stroke risk indicator to a user or a process.Type: ApplicationFiled: November 29, 2017Publication date: June 7, 2018Inventors: Elizabeth Mary Annoni, Pramodsingh Hirasingh Thakur, Qi An, Sandra Nagale, Bryan Allen Clark, Thomas Christen, Edward A.

Publication number: 20180153477Abstract: This document discusses, among other things, systems, devices, and methods for detecting stroke in a patient. A system may comprise a sensor circuit for sensing in a patient at first physiological signal and a second physiological signal or a functional signal. A stroke risk circuit may establish a physiological trend from at least the first physiological signal over time, and generate a stroke risk indicator using the physiological trend and the second physiological or functional signal. Indications of behavioral or cognitive impairment may also be used in stroke risk indicator generation. The system includes an output unit that outputs the stroke risk indicator to a user or a process.Type: ApplicationFiled: November 30, 2017Publication date: June 7, 2018Inventors: Sandra Nagale, Elizabeth Mary Annoni, Bryan Allen Clark, Kyle Harish.
