The purpose of this study is to investigate if the investigational device can support individuals who are at high risk of death due to biventricular heart failure and are eligible for a heart transplant. Biventricular heart failure is a condition where both sides of the heart are not functioning properly, and this study seeks alternatives for those for whom the 70cc Total Artificial Heart is not suitable.

Participants in the study will undergo procedures involving the investigational device, which aims to provide support for their heart condition. The study will closely monitor participants to assess the effectiveness and safety of the device in managing severe heart failure.

• Who can participate: Adults who are at risk of imminent death due to biventricular heart failure and have two functional atrioventricular valves may participate. Participants must have adequate room in the chest and be eligible for a heart transplant.
• Study details: Participants will engage in procedures involving the investigational device to assess its support capabilities. The study will not include any payment for participation.
