Driveline
The Driveline consists of two cables:
• The Pump Cable, which extends from the LVAD through the skin
• The Modular Cable, which connects the Pump Cable to the System Controller
The Driveline contains six wires: three primary wires and three backup wires. These wires power
the Pump Motor and facilitate communication with the System Controller.
To reduce infection, the Driveline is covered with woven polyester, which encourages tissue
ingrowth. Over time, tissue bonds to the textured material and anchors the external surface of the
Driveline to the surrounding tissue. After emerging from the body, the Driveline has a Modular
Connector that joins the Pump Cable to the Modular Cable. The Modular Cable then has an
electric connector that attaches to the System Controller.
Experience with other left ventricular assist devices has shown that wear and fatigue of the
Driveline may result in damage that can interrupt device function. Such damage may require
another operation to replace the Pump, or may result in death. For information about caring for
the Driveline, refer to
Care of the Driveline on page 8-5.
