Prospective, Single-Arm, Study to Assess the Safety and Performance of the TB1-K Device for Organ Preservation in Donor Kidneys for Transplantation

Prospective, Single-Arm, Study to Assess the Safety and Performance of the TB1-K Device for Organ Preservation in Donor Kidneys for Transplantation

TB1-K Device is an organ preservation and transportation system, using ultrasound technology with a cooling system to preserve the organ in optimal conditions during transport to the transplant recipient.

This is a prospective, single-arm, multi-center study comparing to a historical control for cold storage.

The study is conducted in accordance with the Standard ISO 14155 (Clinical investigation of medical devices for human subjects - Good clinical practice), and other legal requirements.

The study objective is to assess the safety and performance of the TB1-K device in donor kidneys intended for transplantation.
