The Coyote Wave Suction Band comes in multiple sizes.

The Suction Band helps create dual suspension in combination with our Proximal, Summit and Low-Pro Locks.
The airtight suspension produces a more intimate fit with added security.

The Wave Suction Band can be used with:

  • Suction Sockets
  • Proximal Lock
  • Summit Lock
  • Low-Pro Lock
  • Air-Lock
  • Easy-Off Lock
  • Lanyard Pin.

The HandsFree Valve or Push Button Valve are recommended to relieve suction when donning and doffing.

Proximal Lock fitted with Wave Suction Band

Dale Perkins, CPO

Dale began to develop unique fitting techniques for above-the-knee amputees after the birth of his second son Matt, an AK amputee. A number of different techniques and components can be determined by the patient’s limb and preferences.

One of the more recent techniques features a casting technique that allows the amputee to comfortably lay down while creating a mould using non-invasive methods.

The fitting is done with a locking system called the Proximal Lock (developed in part by Coyote P&O) along with a gel liner. These two components combine a good fitting "suction" system, with a back-up locking mechanism which also controls rotation.

This results in optimal comfort and convenience and does not require space at the bottom of the limb, helping to maintain a correct knee centre.

Billing:   The Proximal Lock will bill just like a distal pin lock system (L5671). Gluing the lock to the liner turns the Proximal Lock from a cushion liner to a locking liner (L5673).

Improved Suspension:   We recommend adding an expulsion valve to most sockets that use the Proximal Lock. This helps with donning and will evacuate the maximum amount of air from the socket which improves suspension and reduces pistoning.

Limb Type:   The Proximal Lock was designed to work with long limbs and can be the primary suspension for patients who may not have room distally for other lock options. The Proximal Lock can be used for short limbs only with a distal pin; in this case, the Proximal Lock will act only as rotational control.

Retrofitting:   The lock can be retrofitted to an existing socket or put on the outside of a test socket.
Test Socket:   Initial fitting of the socket should be done without the lock. For extended test periods the lock can be retrofit to the socket.
