Abstract
The present disclosure is directed to systems and methods for measuring pressure within a patient. In some implementations, an active implantable sensor is provided that is configured to continuously or periodically obtain pressure signal measurements from within a heart of a patient. The AIS can have an operational lifetime up to or exceeding 5-7 years, and can be configured to continuously or periodically transmit recorded information or data or statistics synthesized from the recorded information to an external device, such as a smartphone, tablet, pc, or other electronic device. Methods of use are also provided.
Claims23
An active implantable pressure sensor, comprising:
- a housing adapted to be implanted within a human heart;
- a cell disposed in the housing;
- a pressure sensor disposed in the housing and configured to measure pressure information outside of the housing;
- a transmitter disposed on or in the housing and configured to transmit the pressure information;
- a supply holding capacitor electrically connected to the cell, the supply holding capacitor being configured to provide current to the transmitter during transmission;
- and
- a microprocessor configured to control transmission of the pressure information by the transmitter, wherein the microprocessor is configured to intermittently turn on the transmitter for a transmit-time sufficient to avoid a supply voltage of the active implantable pressure sensor from collapsing and turn off the transmitter for an off-time sufficient to allow the cell to recharge the supply holding capacitor above a recharge threshold.
