“…Generally, extracorporeal devices such as the Bio-Pump (Medtronic, Inc., Minneapolis, MN, USA) (3), CentriMag Ventricular Assist System (Levitronix GmbH, Zurich, Switzerland) (4), Abiomed BVS 5000 (ABIOMED, Inc., Danvers, MA, USA) (5), and Thoratec VAD (Thoratec Corp., Pleasanton, CA, USA) (6) have been used for right ventricular support. Because these devices are extracorporeal devices and only require an inflow and outflow cannula inside the body, implantation of these devices may not interfere with the implanted LVAD.…”

The DexAide right ventricular assist device (RVAD) has been developed to provide an implantable RVAD option to surgeons. The aim of this study was to determine the optimal cannula design and optimal implantation location of the DexAide RVAD in preparation for its clinical use. Separately, a HeartMate XVE left ventricular assist device (LVAD) and CorAide LVAD models were implanted into the preperitoneal and right thoracic space, and the anatomical fit of the DexAide RVAD was evaluated in five preserved human cadavers. The DexAide RVAD inflow cannula was inserted through the diaphragmatic surface of the right ventricle and the outflow was directed to the pulmonary artery. Right thoracic implantation of the DexAide RVAD provided an excellent fit with either the HeartMate or CorAide LVAD in all cadavers. The results of this study will guide improvements in the designs of cannulae and implantation of the DexAide RVAD in future clinical applications.

“…10 However, in a permanently implantable biventricular bypass system or for bridge to transplantation, ventricular cannulation, especially the RVAD, has the advantage of providing a greater VAD flow rate for a longer time than the atrial cannulation such as the Thoratec BVAD system. 11 If there is a possibility of myocardial recovery, biventricular unloading by adequate drainage from the ventricle will be more effective than improper unloading of the insufficient atrial drainage. 7 Therefore, our inflow cannula for a BVAD has been developed as a ventricular drainage.…”

A newly designed flexible inflow cannula has been developed for a biventricular assist device (BVAD). The inflow tip was designed for long-term ventricle drainage. Considering the anatomic differences between the right and left ventricles, a flexible inflow cannula, as a mass production model with a titanium tip, was developed and investigated in chronic BVAD animal experiments using the NEDO permanently implantable centrifugal blood pump. These flexible inflow cannulae consist of flexible plastic tubing with wire supported, titanium left and right tips. The right titanium inflow tip was designed with inner and outer stoppers to be inserted into the right ventricle wall and a beak shape to avoid sucking. The left tip was designed to be inserted into the left ventricle cavity. Five chronic BVAD bovine studies were performed to investigate the new beak shaped titanium tip. In these studies, the new beak shaped titanium tip and cannula prevented stenosis by a proliferation of pseudoneointimal, and supplied adequate blood flow to the pump without sucking. This newly designed inflow cannula with the beak shaped titanium tip was successfully implanted for 90 days. ASAIO Journal 2004; 50:381-386.
