A system for measuring quantitative CSF flow in shunt tubing implanted under the skin. The system includes an array of thermosensors 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 condictivity, 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.

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.

A61M 5/00

604 9

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.

Methods and devices 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 sensor configurations, or by using other temperature sensor arrangements, or by using a temperature sensitive material, which are positioned over, or in the vicinity of, the CSF shunt in substantially an upstream and downstream orientation. A temperature source, e.g., a cooling agent, is then applied at a predetermined location with respect to the measurement pad that is insulated from the temperature sensors, or to the temperature sensitive material. The movement of this temperature “pulse” is detected by the temperature sensors, or temperature sensitive material, via the shunt tubing as the CSF carries the temperature pulse while a control sensor detects the pulse via convection through the skin. The temperature data from these sensors are provided to a CSF analyzer that subtracts the control sensor data from each of the other sensors for determining a CSF shunt flow status or flow rate. A reader is used to optically or electrically detect the changes in the temperature sensitive material for determining a CSF shunt flow status or flow rate.

The novel embodiments include a method, system and device for measuring a fluid characteristic in a conduit. The novel method includes applying a planar force to the conduit and receiving a pressure from the conduit. The pressure is responsive to the fluid and the conduit, where the pressure is received within a predetermined area. Also, the novel method includes processing the pressure to determine the fluid characteristic. The novel device includes a support structure for supporting the conduit and a sensor head in cooperation with the support structure. The sensor head applies a planar force to the conduit, and has a portion least equal to an outer radius of the conduit. The device also includes a pressure transducer located on the sensor head. The pressure transducer receives a pressure from the conduit that is responsive to the fluid and the conduit.

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.

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 carotid 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.
