Technology Pipeline

ReliantHeart is committed to maintaining its pioneering heritage in the VAD Industry through its
commitment to continual improvement and forward compatibility. Forward compatibility is the ability of a design to gracefully accept input intended for later versions of itself. Our philosophy is to leave no patient behind. Future introductions will include the direct implant aVAD that can be upgraded to TET without pump replacement.

The new intraventricular aVAD


aVAD heart image2ReliantHeart is committed to providing the clinicians more freedom in the LVAD implanting technique. The intraventricular implant places much of the aVAD inside the ventricle and away from uncomfortable interference outside the ventricle. The aVAD has had approval for distribution and clinical investigation in Europe. In the United States, the aVAD is in preclinical testing and is expected to enter an FDA IDE trial in 2019. Our strategy of Forward Compatibility is designed to leave no patient behind.

Please view this video below for more information about the new intraventricular aVAD.


Service first instead of replacing a VAD

The VAD Maintenance System

The VAD Maintenance System is currently under development and investigation at ReliantHeart. LVADs manufactured by other companies are often removed and replaced when occluded and desirable minimum flows can’t be achieved. Why replace a VAD when servicing it is an option?

Peripheral Accessories

Disconnectable DrivelinePicture1

ReliantHeart is developing a Disconnectable driveline.  The male end of the aVAD and HA5 and the Flow Probe will each be plugged into a female plug. The pump line will extend 15 inches from the aVAD into the abdomen. In case of the need to replace the driveline, the procedure is to disconnect the pump line and replace the external driveline.

Conquest Controller 3G

All carriers are reallocating capacity to more advanced 3G wireless networks in order to provide a more reliable experience. The Conquest Controller is 3G.  Remote Monitoring of the HA5 and aVAD depends on modern digital communication available seamlessly from more than 450 worldwide digital carriers. The controller switches from one carrier to another automatically, and transmits digital updates all the time, anytime from anywhere. The Liberty system controller will also be 3G.


TET Ready aVAD and HA5

By 2017, the aVAD and HA5 devices will be very power efficient. They will draw just 3.5 watts of power making them Transcutaneous Energy Transfer (TET) Ready wireless devices. We refer to this and other initiatives derived from ReliantHeart’s development platform as “forward compatibility”. We refer to TET as Liberty. Allowing the patient the freedom to live a life of Liberty – no annoying wire penetrating the body.






Keep Track of INR and Improve Outcomes

INR is included and available at no charge to all HeartAssist patients. INR can be taken with the Roche CoaguChek meter provided by ReliantHeart. INR values are recorded and uploaded to the clinician/patient dashboard so that INR readings can be supervised. If INR values fall below minimum or exceed maximum allowed, an email or text message will be received by the supervising clinician. Future innovations will allow the bluetooth input of INR, weight and blood pressure. It is believed that if INR is maintained between upper and lower limits, and blood pressure and weight are managed, then VAD patients are likely to experience improved outcomes.

INR Tracker

The INR Tracker personal screen provides the user a convenient place to log and monitor values important to creating improved outcomes.

INR transmits INR, and eventually weight and blood pressure readings, directly to for supervision by the patient clinical team. INR is available at no charge to any person interested in tracking INR and hungry for vitamin K dietary advice. provides the clinician a window to the patient LVAD. The site and patient secure window receives data from the HeartAssist in real-time and from INR when the patient enters INR values. As INR Tracker makes additional patient input available such as blood pressure, weight, and body temperature, those readings will also be transmitted to

And if VADLink were to report a change in flow relative to power, or a change in power relative to flow, it may signal that the HeartAssist is in need of maintenance. It is now common practice to remove and replace an LVAD instead of servicing an LVAD. The ReliantHeart VAD Maintenance System is currently under development at ReliantHeart and will soon be available.
