Coyote Vacuum Technology
Why vacuum?
Unlike conventional prosthetic suspension methods, our hypobarric socket technology increases tissue profusion, physiologically improving limb health
Tissue Perfusion
Having a healthy residual limb starts here.
Tissue perfusion socket technology pulls tissue to the socket wall
Puck technology helps pull blood, lymph and nutrients flow into your residual limb, making tissue healthier and stronger.
Tissue Compression
Other suspensions (tissue compression) pin, sleeve, lanyard & suction liners compresses healthy tissue constricting blood flow
Conventional suspension technology requires the amputees to progressively tightening the socket either by adding socks or further compressing the residual limb as essential limb fluid & volume is lost through out the day.

Unparalleled suspension
The SmartPuck was created by Clinical Prosthetists seeking to solve some of the most frustrating issues with existing socket technology and the all to common problems with elevated vacuum.
Frustrated by external vacuum systems that perpetually leaked, produced fluctuating levels, and limited foot choice.
They designed the first Internal intelligent socket system with integrated elevated vacuum technology that can actually make you feel like your prosthesis is a part of you.
Puck Technology.
The Secret is Inside (Literally)
PUCKS are internal vacuum systems
(The entire vacuum pump is contained inside the socket).
This is why pucks work so much better than external vacuums. Because the puck is inside the negative pressure environment, there is no place to leak vacuum.
The Internal Vacuum difference & Why Internal Is Better…
USER ADJUSTABLE
Select the vacuum level that feels right for you.
LIGHT WEIGHT
and located close to the socket so there is no pendulum effect.
WIDER FOOT SELECTION
Due to low puck build height, pucks are the lowest build height in the industry. Which means more component choice when selecting prosthetic knees and feet.
FULL VACUUM
from step one. Walking is not necessary to achieve vacuum.
STREAM LINED AND PROTECTED
Because the puck is actually inside the socket, your system is safe from impacts, dust, water etc.
BUILT IN NEGATIVE PRESSURE TANK
This reservoir adds extended
vacuum life to the socket.
SELF SEALING DESIGN
Makes your socket air tight.
NO LEAKY ATTACHMENT PLATES
This is a common way to port the vacuum line into the socket. Over a short period of time they loosen up and can begin to leak vacuum.
SOFT DISTAL END
Interface option improves comfort 100%.
NO HOSES OR PORTS
There is no where your Puck can leak vacuum other than the sleeve or sealing liner.
How the Other Guys Do it… They use Ports, Plates, and Hoses.
All of which can contribute to leaks and fluctuating vacuum levels in your socket.
Porting In With a Hole / Valve Drilled Into Socket Wall With a Hose Running To Vacuum Pump.
Lamination Plate That is Sandwiched Between the Inner & Outer Laminations
UNDERSTANDING Problems with Traditional External Electric & Mechanical Vacuums (weight/motion activated vacuum pumps)
Mechanical Vacuums often provide a fluctuating level of vacuum throughout the day due to the large number of leak points in the system. This makes the Prosthesis feel loose and disconnected after short periods of rest.
MECHANICAL PUMPS REQUIRE MULTIPLE STEPS
User must walk a number of steps before vacuum is achieved in the socket. The Prosthesis will feel loose as the user begins walking, until the vacuum level rises.
LEAKY HOSES
Need we say more… Who wants a hose running up their leg anyway?
PISTONING
Mechanical Pumps allow the limb to piston up and down inside the socket until vacuum is achieved.
LEAKY SOCKET PORTS
installed through the socket wall are a consistent source of vacuum leaks.
PUMP BLEED
No matter what external vacuum pump, the fittings, connections and valves inside the pump all bleed vacuum.
LEAKY ATTACHMENT PLATES
This is common way to port the vacuum line into the socket. Over time these plates can loosen up and cause vacuum leaks.
NO ADJUSTMENT
Mechanical vacuums have one vacuum level and that’s it!
BUILT IN VACUUM RANGE
Most External electric pumps have a built in range (a time delay to stop the pump from turning on until the vacuum level drops below a certain level). This creates the illusion the vacuum level is staying the same… when in fact it is fluctuating and leaking vacuum.
LACK OF FOOT CHOICE
either because the foot is the actual vacuum pump OR the Vacuum Pump is inline (located between the socket and foot), this takes up valuable space and does NOT allow for higher clearance feet that offer more energy return.
WEIGHT
Mechanical Pumps can be heavy. The farther the Pump is from the socket the heavier it will feel. (pendulum effect)
Understanding Vacuum Signatures
SmartPuck Constant Vacuum Systems
SmartPuck Technology (Blue) maintains a CONSTANT vacuum level in the socket at all times. The entire vacuum system is located inside the socket (negative pressure environment) making the SmartPuck the most air tight vacuum system in the industry. ON Demand Puck technology (Green) utilizes a negative pressure reservoir to extend the vacuum life of the socket all day.
THE OTHER GUYS External Vacuums Fluctuate in Vacuum Level
Mechanical vacuums produce an “All or None” signature. Meaning that you have no ability to lower or adjust your vacuum level which is critical because no two amputees are the same. Vacuum typically bleeds out of the socket when the user is at rest. Because the system is external it is more prone to vacuum leaks. Complete vacuum bleed out can occur in as little as two hours. Mechanical systems allow the limb to piston inside the socket before vacuum is achieved by ambulating.
THE OTHER GUYS External Vacuums Fluctuate in Vacuum Level
External electric vacuums typically operate in a set range. The set range is a delay in how much vacuum can be lost before the vacuum pump turns back on. External systems bleed vacuum from hoses, adaptor plates and actual fittings within the pump itself. The delay creates the perception the socket is not loosing vacuum and turning on as frequently. Some External electric pumps cannot start against back pressure and require a drop in pressure in order to restart the pump.
