First Claim
1. A method, comprising:
- positioning a distal end of a ventricular catheter within a ventricle;
coupling a proximal end of the ventricular catheter to a valve inlet formed on an implantable valve, and coupling a valve outlet formed on the valve to a drainage catheter such that fluid flows from the ventricle through the valve to the drainage catheter; and
using an external reading device to obtain first data telemetrically from a pressure sensor disposed in the valve and including a first antenna, and to obtain second data telemetrically from a radio frequency identification tag disposed in the valve as a physically separate component from the pressure sensor, the radio frequency identification tag including a second antenna, and the first data being indicative of a pressure measurement obtained by the pressure sensor, and the second data including non-pressure measurement data.

Abstract
Devices and methods useful for storing and retrieving information related to a medical device such as an implantable valve or an implantable sensor are disclosed. An implantable valve can include a valve housing adapted to receive fluid flow therethrough between a valve inlet and a valve outlet. A valve assembly can be disposed within the valve housing and adapted to control a rate of fluid flowing through the valve housing. The implantable valve can also include a radio frequency identification (RFID) tag associated with the valve housing, adapted to store data, and including an antenna for communicating stored data to an external reading device. The RFID tag can store data related to, for example, a patient, a pressure setting of the valve assembly, and/or pressure sensor disposed within the valve. The RFID tag can also store an identifier that identifies the implantable valve, a pressure sensor disposed in the valve housing, a patient associated with the implantable valve, and/or patient clinical history.
