A pressure sensing catheter having a pressure sensor and an antenna that is coupled to the pressure sensor, e.g., by a connector, are provided. The pressure sensor can be adapted to measure a pressure surrounding the catheter, and the antenna can be adapted to telemetrically communicate the measured pressure to an external device. In an exemplary embodiment, the antenna, pressure sensor, and/or connector are hermetically sealed, e.g., by the catheter and/or a coating, to prevent the antenna, pressure sensor, and connector from coming into contact with fluid, thereby allowing the catheter to be permanently implanted or otherwise used for long term use. Exemplary methods for manufacturing and using pressure sensing catheters are also provided.

Pressure sensing devices

Pressure sensing valve

An electrokinetic actuator for fluid flow titration including two chambers separated from one another by a porous dielectric disposed therebetween. A plurality of electrodes are disposed about a perimeter of the first and second chambers. Polar electrolyte disposed within the actuator is able to pass through the porous dielectric between the first and second chambers upon the application of an electric field or electric potential to the plural electrodes. A mechanical valve actuation mechanism connected to the second chamber allows for fine titration of fluid flow using electro-osmosis, including full-flow and/or complete cut-off. The polar electrolyte is isolated to prohibit intermixing with a fluid being titrated (such as cerebrospinal fluid).

Electrokinetic actuator to titrate fluid flow

This invention relates to achieving or improving uniform distribution of fluid flow in medical devices such as when combined with antibiotics impregnated in a catheter and/or with a drug-eluting catheter to further inhibit the catheter from becoming occluded by debris in the CSF or by bacterial biofilm formation or tissue proliferation in the catheter.
