Elastimed is developing a compression stocking, made from smart materials, that mimics rhythmic calf muscle contractions and stimulates blood flow. 

There is a clear need in the compression therapy market for increased compliance, which improves treatment and prevents symptoms such as swelling, blood clots, and leg ulcers from returning.

The Elastimed Opportunity

  • $3.3 billion medical compression market
  • Large target market
    • 40% of the global adult population suffer from CVI (impaired functionality of valves in the legs)
    • United States and EU: 790,000 people annually suffer from DVT; in the United States, 3 million people suffer from chronic lymphedema (damage to the lymph nodes often caused by surgery or cancer treatment)
  • Improves compliance
  • Highly effective, easy-to-wear, affordable treatment option
  • Functional prototype of the stocking

Elastimed’s Novel Product

Elastimed is developing a compression stocking, made from smart materials, that mimics rhythmic calf muscle contractions and stimulates blood flow. Based on proprietary technology that utilizes Electro-Active Polymers (EAPs), Elastimed’s stocking stretches and contracts when stimulated by an electric pulse (generated by a 3V battery).

These unique characteristics, combined with low-cost materials and a high level of control, enable the Elastimed stocking to provide patients with a highly effective, easy-to-wear, and affordable treatment option. Read more about the idea behind the Elastimed stocking.

Background & Market

Compression Therapy = 60% Noncompliance. Compression therapy is used to treat venous and lymphatic diseases by applying pressure to the lower limbs. Unfortunately, up to 60% of patients discontinue wearing compression stockings due to their tight fit and difficulty in putting them on and taking them off, a task especially problematic for the elderly, obese, and arthritis sufferers.

A much more expensive alternative: pneumatic compression devices. These devices use an inflatable garment (sleeve) to mimic rhythmic calf muscle contractions. Today’s cumbersome garments have noisy compressors and heavy air pumps, which limit patient mobility and cause discomfort.

An Active $3 Billion Market. ElastiMed’s $3.3 billion opportunity is in the medical compression stocking market addressing lymphedema and edema. The market’s 5% CAGR is driven primarily by increasingly large numbers of elderly and diabetic patients, both populations with a high incidence of venous diseases.

It is estimated that about 40% of the global adult population suffer from edema caused by CVI (impaired functionality of valves in the legs). CVI often results from DVT. In the United States and EU, 790,000 people yearly suffer from DVT. In the United States, 3 million people suffer from chronic lymphedema (damage to the lymph nodes often caused by surgery or cancer treatment).

Leading players include BSN Medical, DJO, Medi, Medtronic, Sigvaris, Tactile Medical.
