  Brand Name: HeartMate Product Name: HeartMate 3" System Controller Model/Catalog Number: 106531US Software Version: N/A Product Description: The HeartMate 3" System Controller acts as the central power and communication hub for the HeartMate 3 LVAS. It passes power from the Power Module, the Mobile Power Unit, Lithium-Ion Batteries, or its own integrated emergency backup supply, down to the LVAD via the Driveline. The HeartMate 3 System Controller constantly monitors system performance through communication with the implanted LVAD and Controller internal measurements and alerts the user to any alarm conditions by activating membrane panel LEDs and integrated audio annunciators. Further information on alarm conditions as well as system status can be attained by the user from the front panel LCD on the System Controller. When connected to a HeartMate Touch" Communication System, the System Controller sends information regarding the System Controller and Pump Status once per second to provide additional information to the user. This link also allows the clinician to set new patient operating parameters (e.g. pump speed) and provides a link for downloading trend and/or event recorder data.

  Brand Name: HeartMate Product Name: HM 11V Li-ion Backup Battery, ABT Model/Catalog Number: 106128 Software Version: N/A Product Description: The HeartMate 11 Volt Lithium Ion Standalone Backup Battery is a component of the HeartMate 3" System Controller and provides power to the System Controller. The HeartMate System Controller is an external device that manages the HeartMate Left Ventricular Assist System (LVAS), including alarms, system monitoring, and communication. It contains an internal 11V lithium-ion backup battery that provides at least 15 minutes of emergency power should the main system power source fail. The backup battery must be properly installed, charges automatically during normal use, and has a 36-month service life from date of manufacture. Component: Yes, HeartMate 3" System Controller
