Pressure sensing valve
First Claim
1. An implantable valve, comprisinga valve housing adapted to receive fluid flow therethrough between a valve inlet and a valve outlet;
- a valve assembly disposed within the valve housing and adapted to control a rate of fluid flowing through the valve housing; and
a sensor disposed within the valve housing and adapted to measure a pressure of fluid flowing through the valve housing,wherein the sensor is disposed within a pressure sensor assembly, the pressure sensor assembly disposed within the valve housing and being in fluid communication with the valve inlet and valve outlet,wherein the pressure sensor assembly includes a domed portion defining a reservoir therein, and wherein the sensor is adapted to measure a pressure of fluid flowing through the reservoir, andwherein the pressure sensor assembly includes a needle guard disposed therein and positioned between the domed portion and the sensor, the needle guard being adapted to protect the sensor from a needle being inserted through the domed portion.

Abstract
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.
