seven (7) days before the procedure.

- Central venous vascular access.

- Capable of Valsalva maneuver with airway pressure > 40 mm Hg for 10 seconds.

- The subject and the treating physician agree that the subject will comply with all
required post-procedure follow-up, and that the patient is capable of correct device
use as outlined in the protocol.

- Written informed consent.

- The subject is currently participating in an investigational drug or another device
study that has not completed the primary endpoint or that clinically interferes with
the current study endpoints.

Summary
Brief summary
Most people with heart failure take a number of medications that work in different ways.
Patients and their families need to keep track of prescribed medications and follow
instructions on how much to take and when to take them. Currently, doctors are guided
primarily by symptoms. The device being studied in this trial (called the HeartPOD™ System)
monitors heart function from inside your body and alerts the patient and physician of
necessary changes to your medication.
