XVIVO Heart Box (XHB) With Supplemented XVIVO Heart Solution (SXHS) Continued Access Protocol (CAP)

Официальное название

PRESERVE CAP: A Prospective, Multi-Center, Single-Arm, Open-Label Study of Hearts Transplanted After Non-Ischemic Heart Preservation From Extended Donors Continued Access Protocol

Обзор

The purpose of this study is to evaluate if Non-Ischemic Heart Preservation (NIHP) of extended criteria donor hearts using the XVIVO Heart Preservation System (XHPS) is a safe and effective way to preserve and transport hearts for transplantation.

Подробное описание

This is a continuation of the PRESERVE IDE trial to provide additional data evaluating the safety and effectiveness of the XVIVO Heart Assist Transport System. The PRESERVE Continued Access Protocol (CAP) will utilize the XHAT System to preserve donor hearts that may not meet current standard donor heart acceptance criteria with the intention of these hearts being transplanted. The CAP has been implemented to allow patients and physicians access to the XHAT System while a Post-Market Approval (PMA) application is being submitted and reviewed.
