Pressure sensing devices

摘要

A pressure sensing catheter (10) having a pressure sensor (16) and an antenna (18) that is coupled to the pressure sensor (16), e.g., by a connector, are provided. The pressure sensor (16) can be adapted to measure a pressure surrounding the catheter (10), and the antenna (18) can be adapted to telemetrically communicate the measured pressure to an external device. In an exemplary embodiment, the antenna (18), pressure sensor (16), and/or connector are hermetically sealed, e.g., by the catheter (10) and/or a coating, to prevent the antenna (18), pressure sensor (16), and connector from coming into contact with fluid, thereby allowing the catheter (10) to be permanently implanted or otherwise used for long term use. Exemplary methods for manufacturing and using pressure sensing catheters (10) are also provided.
