Patent number: 10744024Abstract: A brace and traction device and associated methods of operation. In one embodiment, the device incorporates a forwardly open head and jaw brace which is adjustably supported vertically above a forwardly collar member. The brace and the collar member are adapted such that the brace is able to mate with the collar member while still being able to rotate to the subject's left and right while remaining planar to the collar member. Adjustment may be accomplished for example manually or via an electronic motor controlled by a control mechanism and microprocessor. The microprocessor may be adapted to store information regarding a user's sessions, and facilitate communication with patient and physician personal devices, thus sending these data from recorded sessions. The processor element may also be adapted to implement therapy sessions based on physician-entered program specifications, or based on pre-programmed specifications.Type: GrantFiled: December 8, 2014Date of Patent: August 18, 2020Assignee: OHANA ALANA, LLCInventors: Andrew Senyei, M. Lou Marsh, Stuart L. Gallant, Stuart Karten, Michael Jacob Rocha, Steven K. Piorek, Eric Olson, Paul Cash

Patent number: 10285598Abstract: Improved apparatus and methods for non-invasively assessing one or more parameters associated with systems such as fluidic circulating systems (e.g., the circulatory system of a living organism). In a first aspect, an improved method of continuously measuring pressure from a compressible vessel is disclosed, wherein a substantially optimal level of compression for the vessel is achieved and maintained using dynamically applied dither perturbations (e.g., modulation) on the various axes associated with the vessel. In a second aspect, an improved apparatus and method are provided for monitoring hemodynamic parameters, such as blood pressure, in a continuous and non-invasive manner while operating under a single unifying scheme. One variant of this scheme using a simulated annealing (SA) type approach to determining and maintaining an optimal operating state.Type: GrantFiled: August 17, 2015Date of Patent: May 14, 2019Assignee: United States GTM Medical DevicesInventors: Andrew S.

Patent number: 9814398Abstract: An improved method and apparatus for non-invasively assessing one or more hemodynamic parameters associated with the circulatory system of a living organism. In one aspect, the invention comprises a method of measuring a hemodynamic parameter (e.g., arterial blood pressure) by applanating or compressing portions of tissue proximate to the blood vessel of concern until a desired condition is achieved, and then measuring the hemodynamic parameter. Such applanation effectively mitigates transfer and other losses created by the tissue proximate to the blood vessel, thereby facilitating accurate and robust tonometric measurement. An algorithm adapted to maintain optimal levels of applanation is also described. Methods and apparatus for scaling such hemodynamic parameter measurements based on subject physiology, and providing treatment to the subject based on the measured parameters, are also disclosed.Type: GrantFiled: December 2, 2013Date of Patent: November 14, 2017Assignee: Tensys Medical, Inc.Inventors: Stuart L. Gallant, Gregory I. Voss, William H. Markle

Publication number: 20170293727Abstract: In some implementations, a user device can assist a user with intelligent blood pressure monitoring. For example, the user device can present notifications and/or reminders that prompt the user to take blood pressure measurements at a prescribed time or according to a prescribed schedule. The user device can automatically determine that the user should or should not take a blood pressure measurement based on the user's context and suggest an alternative time for taking the blood pressure measurement. For example, the user's context can include the user's physical and/or psychological state inferred based on sensor data, application data, and/or other detectable information. In some implementations, the user device can automatically monitor the user's blood pressure and take blood pressure measurements based on user context triggers.Type: ApplicationFiled: April 8, 2016Publication date: October 12, 2017Inventors: Erno H.

Publication number: 20150265218Abstract: Improved methods and apparatus for non-invasively assessing one or more parameters associated with fluidic systems such as the circulatory system of a living organism, when such parameters are potentially affected by other concurrent events. In one exemplary embodiment, apparatus and methods for compensating for occlusive events (e.g., pressure cuff inflation) occurring ipsilateral to the location of parameter measurement are disclosed. Upon passive detection of signal degradation resulting from the event, the apparatus selectively enters a “wait state” wherein further processing of the hemodynamic data is suspended until the degrading event subsides. This behavior mitigates any adverse effects the event might have on the accuracy of the representation of the measured hemodynamic parameter generated by the system. In another exemplary embodiment, the measured data is analyzed in order to classify the type of event (e.g.Type: ApplicationFiled: February 23, 2015Publication date: September 24, 2015Inventors: GREGORY J.

Patent number: 8328727Abstract: An improved method and apparatus for non-invasively assessing one or more hemodynamic parameters associated with the circulatory system of a living organism. In one aspect, the invention comprises a method of measuring a hemodynamic parameter by measuring a non-calibrated value of the parameter non-invasively, and inducing a stress of the circulatory system while measuring a second parameter. The response of the circulatory system to the stress is determined directly from the subject, and a calibration function is derived from the response and applied to the non-calibrated measured value to produce a calibrated measure of the actual value of the hemodynamic parameter. Methods of using backscattered acoustic energy for determination of hemodynamic markers are also disclosed.Type: GrantFiled: May 18, 2006Date of Patent: December 11, 2012Assignee: Tensys Medical, Inc.Inventors: Frank R.
