摘要： 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.

摘要： A system and method for non-invasively detecting intracranial pressure (ICP) of a living being by detecting impedance mismatches between carotid arteries and cerebral vessels via a reflection of the carotid pressure waveform using a pressure sensor positioned against the palpable artery, as well as analyzing the reflection and comparing the analysis with known cerebral vasculature data, to calculate ICP non-invasively. A remote blood pressure waveform can also be used to compensate for blood system impedance.

摘要： Methods and devices for testing for the presence, absence or flow rate in a subcutaneous shunt tubing using a measurement pad having a plurality of temperature sensor configurations which are positioned over, or in the vicinity of, the CSF shunt in substantially an upstream/downstream orientation. A temperature source is then applied at a predetermined location with respect to the measurement pad that is insulated from the temperature sensors. This temperature "pulse" movement is detected by the temperature sensors via the shunt tubing as the CSF carries the temperature pulse while a control sensor detects the pulse via skin convection. Temperature sensor data are provided to a CSF analyzer that subtracts control sensor data from the other sensors for determining a CSF shunt flow status/rate. A reader is used to optically or electrically detect the changes in a temperature sensitive material for determining a CSF shunt flow status or flow rate.

摘要： 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.

摘要： A pressure sensor that is implantable within a living being that wirelessly provides pressure data within the living being to a wireless receiver. The pressure sensor includes an elastic membrane to which at least one capacitive actuator is coupled for applying a known force to the membrane to determine membrane characteristics. The pressure sensor includes a force transducer contacting the membrane for determining the pressure within the living being and which includes an internal calibrating force mechanism. This calibrating force mechanism permits force transducer displacement away from the membrane where a zero force transducer reading is taken and then applying a calibrating force and taking another reading. From these two points, a force transducer characteristic is derived and, along with membrane characteristics, an accurate pressure within the living being is obtained from the sensor. An alternative embodiment replaces the capacitive actuators with a known mass and an external vibratory source.

摘要： 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.
