Patent number: 10953284Abstract: A system, methods and apparatus for powered monofin that propels a swimmer through water uses one of two modes of power: 1. An electric-assist mode, in which the propulsor responds to a swimmer's kick by multiplying the work of the swimmer; 2. Inverse mode, in which the propulsor deactivates when the swimmer is working. In this mode, propulsion is inversely related to the work of the swimmer. As the swimmer does more work, power from the monofin is reduced, to a predetermined, average level of propulsion. As the swimmer does less work propulsion increases to the predetermined level.Type: GrantFiled: August 30, 2019Date of Patent: March 23, 2021Assignee: Amphi Americas LLCInventors: Marek Swoboda, Michal Swoboda

Patent number: 10499816Abstract: An apparatus and method that utilizes thermal dilution to detect a wide range of flow rates and/or flow status in cerebrospinal fluid (CSF) shunt systems. The use of a large cold source in combination with thermosensor pad of a particular construction provide a fluid flow analyzer with the ability to detect very low levels of CSF flow. In addition, a method for adjusting thermal dilution readings to compensate for varying shunt catheter depth is shown and for determining a steady state of the thermal dilution readings. The thermosensor pad is conformable to a patient's skin contour thereby making the apparatus and method less sensitive to ambient temperature errors and, as a result, more accurate in assessing CSF flow. Furthermore, a software error check is provided for identifying poor sensor-to-skin contact for alerting an operator to re-apply the thermosensor pad to correct, as well as a post-test check to determine if temperature data is reasonable before determining flow status or flow rate.Type: GrantFiled: November 26, 2013Date of Patent: December 10, 2019Assignee: ShuntCheck, Inc.Inventors: Frederick J.

Patent number: 9138568Abstract: An apparatus capable of generating flow in cerebrospinal fluid (CSF) shunt systems by vibrating the shunt, tubing or shunt valve dome, or applying cyclical pressure to the various parts of the shunt system. A method of generating flow and method of using the apparatus in shunt patency assessment, for example, hydraulic resistance assessment, is also disclosed. The apparatus allows, in conjunction with a thermal dilution method or radionuclide method, a quick CSF shunt patency assessment based upon CSF shunt resistance and not upon CSF flow or intracranial pressure (ICP) separately. This provides a more objective measure of shunt obstruction compared to other methods. Furthermore, the apparatus can be used to enhance flow in shunts, identify partial occlusion before symptoms occur, differentiate between patent, partially-occluded and occluded shunts. The apparatus can be used to generate flow in shunts if there is a need to lower ICP or move drugs administered via an injection chamber or a shunt dome.Type: GrantFiled: May 19, 2011Date of Patent: September 22, 2015Assignees: ShuntCheck, Inc., The Children's Medical Center CorporationInventors: Marek Swoboda, Matias Gabriel Hochman, Mark Evan Mattiucci, Frederick J.

Publication number: 20150201882Abstract: An apparatus and method for determining a continuous CSF flow rate in an implanted CSF shunt in real-time. The system/method utilize a Peltier sensor formed on a flexible pad that is placed against the patient's skin. The Peltier sensor includes a Peltier device coupled to a thermal resistor that is contact with the patient's skin over the CSF shunt location. The Peltier device is operated continuously, controlled by the Peltier temperature sensor to a predetermined temperature that is below the patient's core temperature to form a temperature differential that causes any heat generated by the skin/CSF flow to be detected by a skin temperature sensor and the Peltier temperature sensor. Upstream and downstream temperature sensors, as well as control temperature sensors, are utilized to form a zero flow rate baseline that is used to calibrate a Peltier signal that corresponds to a real-time CSF flow rate.Type: ApplicationFiled: July 25, 2013Publication date: July 23, 2015Inventors: Marek Swoboda, Matias Gabriel Hochman

Patent number: 9072866Abstract: A method and device for testing for the presence, absence and/or rate of flow in a shunt tubing implanted under the skin by using a measurement pad having a plurality of temperature sensors, one of which is aligned with the shunt and the other sensors being symmetrically displaced on either side of the first temperature sensor in a direction transverse to the shunt tubing. These “outer” temperature sensors act as control temperature sensors. A temperature source, e.g., a cooling agent, positioned within an insulated enclosure, is then applied at a predetermined location on the measurement pad that is insulated from the temperature sensors. The movement of this temperature “pulse” is detected by the shunt-aligned temperature sensor via the shunt tubing as the CSF carries the temperature pulse while the control sensors detect the pulse via convection through the skin. The temperature data from these sensors are provided to a CSF analyzer that determines a CSF shunt flow status or flow rate.Type: GrantFiled: August 29, 2013Date of Patent: July 7, 2015Assignee: Neuro Diagnostic Devices, Inc.Inventors: Frederick J.

Publication number: 20150045717Abstract: A system for measuring quantitative CSF flow in shunt tubing implanted under the skin. The system includes an array of thermo-sensors clustered in three sections, cooling device, placed on the skin surface and an associated data acquisition and analysis device. Two sensor sections are placed over the shunt on the skin and measure real time temperature responses related to CSF movement. One array placed adjacent the cooling device collects data on thermal properties of skin including skin thermal conductivity, specific heat, diffusivity, perfusion, and thermal inertia. The method involves assessing thermal properties of skin and measuring CSF flow in shunt tubing. The method is useful for shunt patency assessment, CSF valve adjustment procedures and CSF flow measurements related to CSF over drainage. Alternatively, only one section of sensors need be used when determining relative CSF flow, without the need to determine thermal skin properties and by applying the cooling device continuously.Type: ApplicationFiled: October 14, 2014Publication date: February 12, 2015Inventors: Marek Swoboda, Matias Gabriel Hochman, Mark Evan Mattiucci, Frederick J.
