Pump Overview
Introduction
72 HVAD® Instructions for Use

Controller (continued)
In patients who may be at risk of catastrophic cardiovascular collapse associated with a pump
shutdown (fused aortic valve, aortic valve that has been sewn shut due to aortic valve regurgitation,
or patients with very poor endogenous ventricular function) ESD education is extremely important
and controller exchanges should be performed in a controlled clinical setting whenever possible.
Controller Care
Once a week: Instruct the patient to inspect the controller power connections and connector
pins for dirt. This inspection can be done while the patient is changing batteries or when
changing from batteries to the AC adapter. Check the power connections on the controller

disconnect the pump to examine the percutaneous lead/controller connection. This connector
should be inspected only during a controller exchange. The patient should not attempt to clean
the controller connectors, but should be instructed to contact their VAD coordinator if they
notice the connectors are dirty. Exterior surfaces of the controller should be cleaned using a
clean cloth. A damp cloth may be used but a wet cloth should not.
Periodically or as needed:
The controller may be cleaned with the following agents:
Alcohol (Isopropyl 90% or Ethyl 70%)
Hydrogen peroxide solution (1.4%)
 n-Alkyl Dimethyl Dibenzyl Ammonium Chloride combined with n-Alkyl Dimethyl Ethybenzyl
Ammonium Chloride (active agent in some disinfecting wipes).
 Silver, ethanol, acetic acid, peroxyacetic acid, hydrogen peroxide solution (active ingredients
of some sporicidal disinfecting wipes)
 UV-C disinfecting wand, one that radiates “short wave” UV-C band rays (100 to 280
nanometers) from a 4 watt bulb (or stronger)
