Capstan System: The "Xbox Master" in Surgical Robotics

Capstan System: An Innovative Model in the Field of Cardiovascular Interventional SurgeryThe Capstan system is an innovative model in the field of cardiovascular interventional surgery, with its components working together to provide a strong guarantee for the precise implementation of the procedure. The system consists of three key parts: the mitral valve implant, the delivery catheter, and the catheter control system.

The mitral valve implant adopts a unique "dual-stent" system, with a valve housing unit of 27 millimeters that provides an effective orifice area (EOA) of 3.3 square centimeters. This design allows the implant to better match the anatomical structure of the human mitral valve, effectively improving cardiac hemodynamics. The delivery catheter, sized at 33Fr, acts as a precise "lifeline," responsible for safely and accurately delivering the mitral valve implant to the target location. The catheter control system serves as the "intelligent brain" of the entire Capstan system, ensuring exact control over the surgical procedure.

The most talked-about aspect of the Capstan system is its unique design that utilizes an Xbox controller for operation. Imagine doctors no longer wielding traditional surgical instruments but instead performing complex surgical procedures by manipulating an Xbox controller, much like operating a game console. This design is not merely for novelty but offers numerous practical advantages.The interface of the Xbox controller is simple and intuitive, allowing doctors to easily navigate the mitral valve anatomy through familiar buttons and joystick operations, achieving precise control of surgical instruments. This significantly reduces the difficulty of surgical operations, making the surgical process smoother and more efficient.At the same time, this design also increases the flexibility of doctors' operations. During the surgery, they can adjust the trajectory, depth, and position of the catheter at any time according to the actual situation, ensuring the safety and success rate of the surgery.

Human Case Details: The Technical Strength Behind a Successful Surgery

At the 2025 Cardiovascular Research Technologies (CRT) conference, Santiago Garcia from Christ Hospital in Cincinnati, U.S., provided a detailed introduction of the two landmark surgeries. The first patient was not a suitable candidate for traditional surgery due to multiple comorbidities. However, with the assistance of the Capstan system, the doctors offered new hope.

During the surgery, the doctor precisely controlled the Capstan system via an Xbox controller. Skillfully utilizing the controller’s buttons and joysticks, they guided the delivery catheter along a complex vascular path with the precision of operating sophisticated equipment, accurately delivering the mitral valve implant to the diseased area.The entire process is like a tense yet orderly "surgical game," where the doctor focuses intently on the screen, continuously adjusting the trajectory, depth, and position of the catheter based on real-time imaging feedback to ensure that the implant perfectly matches the patient's mitral valve anatomy.

This surgery took approximately 120 minutes and ultimately achieved a "very good" outcome. Postoperative examinations showed no evidence of paravalvular leakage (PVL), mitral regurgitation (MR) was completely eliminated, and the patient's cardiac function significantly improved.

The second surgery performed the next day was also successful, with the operation time shortened to 90 minutes.This not only reaffirms the effectiveness and reliability of the Capstan system but also highlights the efficient operational capabilities of the medical team after mastering this technology. In this surgery, the doctors successfully completed the mitral valve replacement with the precise control provided by the Capstan system. The patient recovered well post-operation, with all indicators normal.

The success of these two surgeries is not only a victory for medical technology but also a blessing for countless patients. They have opened up a new treatment path for patients who were previously unable to undergo traditional surgery due to complex conditions. The application of the Capstan system has shown us the enormous potential of robot-assisted surgery in the field of cardiovascular disease treatment. With its precision and minimally invasive characteristics, it brings patients smaller trauma, faster recovery, and better treatment outcomes. We believe that in the future, as this technology continues to develop and improve, more patients will benefit from it and regain a healthy life.
