Insync Sentry™

The breakthrough feature that makes thoracic fluid measurement possible is called OptiVol Fluid Status Monitoring, which measures changes in impedance. Using very low electrical pulses that travel across the thoracic cavity, the system can measure the level of resistance to the electrical pulses, which indicates the level of fluid in the thorax. Since normal fluid levels may vary from patient to patient and fluid accumulation can be either slow or rapid, OptiVols ability to measure fluid status trends over time can provide important insights in conjunction with ongoing monitoring of other patient symptoms.

InSync Sentry will provide vital patient information to physicians who implant CRT defibrillator systems and also to physicians who manage the ongoing care of heart failure patients. In the future, Medtronic plans to offer various methods to access information gathered by the InSync Sentry system, including the Internet and through wireless transmissions that wouldn't require direct patient interaction
