Alpha® Design Liner

When a pre-defined profile will not cater to your patient’s needs, a custom solution is required. Alpha design liners give the clinician full control of how the interface material is built up in relation to their model. Whether it is building up for increased protection over a bony prominence, or filling in deep and irregular scarring; a design liner can provide a comfortable fit for the most irregular shapes. Available for both transtibial and transfemoral liners.

Interface options

Alpha design liners come with a choice Hybrid gel, Classic gel or Express Silicone.

Hybrid gel was designed to combine the comfort of Classic gel with the durability of silicone. This all-round liner is as the name suggests – the best of both. With sufficient flow for bony prominences and suitable stability to control loose tissue, the added durability, compared to Classic gel, means higher activity users can achieve a comfortable fit with less regular liner replacements.

Alpha Classic gel consists of a skin-friendly blend of thermoplastic elastomer (TPE) gel with mineral oil and vitamin E. Alpha Classic Gel has been thoroughly tested for skin reaction and received ‘no reaction’ scores.

WillowWood’s Express Liner is a softer-durometer silicone that replicates the feel and comfort of TPE gel liners.

Design Liner Profile

Gel may be up to 25mm thick, which is especially useful for invaginated or bony limbs. Gel on the proximal edge and behind the knee may be as thin as 3mm, providing greater comfort and range of knee motion.

  • Custom design, 3-25mm thickness as required

Fabric options

Alpha design liners come with a choice of either Original or Select fabrics.

The Select fabric is WillowWood’s most durable and comfortable offering. By combining two distinct materials, it offers support, compression and flexibility. To prevent pistoning, the majority of the fabric has unidirectional stretch, meaning a distal matrix is not required. This allows easy donning and accommodation of volume changes without the need for a new liner. To reduce shear stress over the patella, there is a multidirectional stretch panel over the knee which improves comfort in flexion.

This Original fabric is a tried and tested material which continues to provide flexibility for comfort and donning, whilst being supportive enough for a good fit. Its smooth finish means it slides on easily and its durability extends the life of the liner.

Standard Umbrella

The standard umbrella has a standard diameter of 68.6mm on all sizes.
