Abstract

A system for in-vivo monitoring of pressure of a body fluid. The system comprises a delivery component and an elongate sensor delivery member shaped so as to pass through the delivery component when it has been inserted in to a patient. A first pressure sensor is positioned at a distal end of the delivery member.

Claims

1. A system for in-vivo monitoring of pressure of a body fluid, the system comprising:

a delivery component;

an elongate sensor delivery member shaped so as to pass through the delivery component when it has been inserted in to a patient; and

a first pressure sensor positioned at a distal end of the delivery member.

2. The system of claim 1, further comprising a signal processing component for receiving data from the first pressure sensor and providing an output to a user based upon the received data.

3. The system of claim 1, further comprising a second pressure sensor configured to be inserted subcutaneously in to a patient in use.

4. The system of claim 3, further comprising means for receiving data from the second sensor and for comparing it to pressure data from the first sensor to provide compensated pressure data to a user.

5. The system of claim 1 further comprising a temperature sensor such that pressure data from the first sensor can be adjusted to remove any temperature related effects by using data from the temperature sensor.

6. The system of claim 1 wherein the delivery member has communication means and power supply means formed therein such that the first pressure sensor is provided with power and the output of the first pressure sensor can be passed through the delivery member to external processing means.

7. The system of claim 1, wherein the first pressure sensor has wireless communication means for communication with an external data receiving device.

8. The system of claim 1 further comprising an alarm device to provide warning if a pressure detected by the system meets a predetermined condition.

9. The system of claim 1 configured to activate a nerve stimulation device connected to the patient to which the system is itself connected, to stimulate the nervous system of the patient to act in response to a predetermined pressure condition detected by the system.

10. The system of claim 1, wherein the delivery component is a cannula.
