A system for better movement

The Kinn™ SYSTEM

Empowering prosthetists with dynamic fit technology

Kinn™

Vessl’s KinnTM Adaptive Volume Management System

The Kinn™ Adaptive Volume Management System empowers patients to have a prosthetic socket that automatically contours to the limb, providing comfort with every step. Engineered to adapt seamlessly to natural fluctuations in limb volume, the Kinn™ system ensures a stable and consistent interface pressure throughout the day. By actively managing volume changes, it enhances fit, reduces discomfort, and provides a reliable, worry-free prosthetic experience.

The Kinn™ system features a vertical shock absorber designed to efficiently dissipate impact with each step, significantly reducing strain and enhancing overall comfort. Utilizing the kinetic energy absorbed from walking, the Kinn™ system powers its automatic volume adjustment mechanism, ensuring a precise fit. Designed for both function and aesthetics, it seamlessly integrates with the distal end of a paneled socket, providing a sleek, low-profile solution. By eliminating the bulky protrusions typically associated with adjustable sockets, the Kinn™ system delivers a streamlined, natural look while optimizing comfort and performance.

Product Features

Volumetric Auto-Adjusting

Automatically adjusts to accommodate limb volume fluctuations. Allows the user to focus on life rather than adjusting their socket.

Consistent Interface Pressure

The user and prosthetist work together to set the ideal socket tension setting, from that point on the Kinn™ system maintains stable pressure on the limb regardless of volume changes.

Vertical Shock Absorber

With up to 8mm of vertical shock absorption, the Kinn™ system reduces the impact of ground reaction forces during initial heel contact. The reduced forces on the residual limb and joints provide a more comfort throughout the day.

 Kinetically Powered

With each step taken, the shock absorber is compressed, and the kinetic energy drives the mechanical volume adjustment system.

 Seamless Socket Integration

The Kinn™ system attaches to the distal end of any socket.  The low profile and anatomic shape allow for all the Kinn™ system's performance without bulky protrusions.

Frequently asked questions

What are the suggested L-Codes for the Kinn™ system?

The recommended L-codes are L5783 and L5988.

Can the Shock absorber be adjusted?

There are 4 shock absorber dampening rings available to match the patient’s body weight and impact level.

What happens if a lace breaks?

Every Vessl product is designed to be as durable as possible, however if a lace does break, it can be replaced by the prosthetist.

What stops the automatic volume adjustment system from overtightening?

There is a mechanical tension limiter that is adjustable by your prosthetist. This setting can be increased or decreased to provide a safe and comfortable fit.

Can I manually adjust the socket tension?

Yes, there is a manual adjustment dial on the side of the Kinn™ system that allows the user to manually tighten the socket when donning or as needed. However, the Kinn™ system will automatically tighten as needed when the vertical shock absorber is compressed while walking.

Does the Kinn™ system need to be charged?

No, the Kinn™ system is a completely mechanical system that functions without electronics. This allows for increased durability and longevity.

How does the Kinn™ system attach to the socket?

The Kinn™ system has two mounting options, a 4 hole attachment plate and a lamination plate. We recommend using the 4 hole plate when using a puck style pin lock that is held in place with 4 screws.

What is the distal attachment?

The distal end of the Kinn™ system has a standard 4 hole bolt pattern for attaching any 4 hole component.
