IMPLANTABLE SYSTEM FOR FLOW MEASUREMENT INCLUDING CHARGE AMPLIFIER
摘要
<p>An implantable medical device lead (70) having a flow measurement sensor (14', 16') mounted thereon is provided with a capsule (72) mounted proximate to the sensor. The capsule is used to house electrical circuitry corresponding to the sensor in order to prevent impedance on conductors of the lead, which gradually decreases over chronic periods, from directly affecting signal transmission between the sensor and the electrical circuitry. The electrical circuitry includes a charge amplifier used for processing signals from the sensor. In some cases, the amplifier can be initially calibrated and periodically tuned so as to have consistent functioning with the sensor over chronic periods.</p>
