Get the most out of Training and Rehab—without risks.
If you need to build strength and you can’t use heavy loads. In rehab or training, to build or maintain muscles. Or to improve your endurance. Maybe you are too weak, or you don’t have oceans of time. Try Blood Flow Training. It restricts blood flow in your limbs’ veins and tricks your muscles into believing they are under heavy loads. And your muscles grow. It is very efficient, requiring only a fraction of the load of heavy-weight training to achieve astonishing results.

This is how it works
Inside Delfi BFR Pro, you find the latest innovative technology to safely regulate and control tourniquet pressure for Controlled Blood Flow Training.
Controlled Blood Flow Training allows patients and athletes to build strength and muscle mass, comparable to high-load training—without stressing the joints.
This makes Controlled Blood Flow Training particularly effective for individuals recovering from injury, surgery, or muscle atrophy, and it is increasingly utilized in physiotherapy, sports performance, pre-operative care, and rehabilitation.
What is Controlled Blood Flow Training?
Controlled Blood Flow Training is a rehabilitation and performance training method that involves applying a specialized cuff to a limb to partially restrict blood flow during low-load exercise. By reducing venous return while maintaining arterial inflow, the muscles believe they are under high-load training, and they begin to grow. The results are astonishing, with outcomes similar to those achieved in high-load training.
By using Controlled Blood Flow Training technology—developed and patented by Delfi—you can be assured that you are using safe and controlled procedures that no one else can match.
Used by professionals worldwide—therapists, trainers, and athletes

Why the science behind Delfi matters to you
Why Choose Delfi for BFR?
Delfi BFR systems are built on decades of surgical tourniquet expertise and designed to meet rigorous medical device standards. Unlike general fitness-focused solutions, Delfi BFR Pro is developed, tested, and manufactured under a certified medical device quality system—supporting consistent performance, safety, and reliability in professional and clinical environments.
Backed by patented and validated technology, Delfi systems enable personalized pressure selection based on individual Limb Occlusion Pressure (LOP)—an approach supported by published research and widely used in clinical and performance settings worldwide.
Delfi’s focus on safety and effectiveness is reflected in its adoption across elite organizations worldwide. Delfi systems are used by leading institutions including the U.S. Department of Defense, U.S. Olympic training centers, NASA, and professional sports organizations across North America, spanning football, basketball, baseball, and hockey.
That’s why Controlled Blood Flow Training matters.
The Science behind Delfi BFR Pro
Engineered technology. Certified standards. Controlled blood flow restriction training.
Two essential technologies that define Controlled Blood Flow Training.
Effective Blood Flow Restriction (BFR) training depends on precise measurement and consistent pressure control. Delfi BFR Pro is built around two foundational technologies that work together to support controlled, individualized BFR application
Limb Occlusion Pressure (LOP)
LOP is the minimum pressure required to occlude arterial blood flow to a limb. Delfi BFR Pro incorporates patented and validated technology designed to automatically determine an individual’s LOP by detecting changes in arterial pulse and calculating a personalized reference pressure.
In BFR training, cuff pressure is commonly selected as a percentage of the individual’s LOP—often within a sub-occlusive range intended to restrict venous outflow while maintaining arterial inflow. This personalized approach supports appropriate pressure selection across diverse users, from rehabilitation patients to high-performance athletes.
Automatic pressure regulation
During exercise, limb volume changes with muscle contraction and relaxation. Without pressure regulation, cuff pressure may fluctuate, potentially affecting consistency of blood flow restriction.
Delfi BFR Pro is designed to actively regulate cuff pressure in real time, adjusting inflation and deflation as needed to maintain a stable target pressure throughout exercise to provide a consistent BFR pressure stimulus. This approach is derived from principles used in surgical tourniquet systems, where maintaining consistent pressure over time is essential.
Controlled by design
Together, personalized LOP determination and automatic pressure regulation form the foundation of Controlled Blood Flow Restriction Training—supporting repeatable, individualized application grounded in medical-grade technology and design principles.
In Blood Flow Restriction (BFR) training, control is central to safety. Key elements such as personalized Limb Occlusion Pressure (LOP) and automatic pressure regulation work together to form a controlled blood flow restriction training system. But meaningful control requires more than claims—it requires verification.
Delfi BFR Pro is built on patented and validated blood flow control technologies and developed within a certified medical device quality framework. These patents protect critical methods for pressure measurement and regulation, while certifications provide independent confirmation that the system is designed, manufactured, and maintained to recognized medical standards.
Built to Medical-Grade Standards
Delfi BFR Pro is manufactured under a globally accredited quality management system and has been assessed for compliance with ISO 13485:2016 and applicable regulatory requirements in the United States (FDA registration), Canada, Europe, Australia, and Japan. Delfi also holds NSAI / MDSAP certification, reflecting ongoing third-party oversight of design, manufacturing, and servicing processes.
Together, Delfi’s patents and certifications provide confidence that Delfi BFR Pro is developed with the rigor, consistency, and accountability expected of medical-grade technology.
