The geko™ device can prevent Deep Vein Thrombosis (DVT)

The geko™ device has been reviewed by The National Institute for Health and Clinical Excellence (NICE) medical technology evaluation program (MTEP) as anti-stasis/DVT prophylaxis solution to specific groups of patients who cannot be served by existing modalities

The recommendations are:

1. The case for adopting the geko™ device is supported for use in people who have a high risk of venous thromboembolism and for whom other mechanical and pharmacological methods of prophylaxis are impractical or contraindicated.

2. The case is supported because of the plausibility that the geko™ device may reduce the high risk of venous thromboembolism in patients who cannot use other forms of prophylaxis, and the low risk of the device causing harm.

The benefits of using geko™

The chart below compares the ease of use of geko™ devices with other devices currently in use that are intended to perform a similar role taken from a recent Device Comparison Study - principal investigators Dr. Arthur Tucker and Dr. Annelie Maass, The Ernest Cooke Vascular & Microvascular Unit, St. Bartholomew's Hospital.

Current DVT prophylaxis

There are several significant disadvantages of the two current methods against which geko™ compares favourably should it be of proven use in the prevention of DVT.

Disadvantages of pharmacological treatment:

  • active bleeding
  • allergic reactions
  • risk of VTE persists for weeks or months after hospital discharge
  • drug interactions with several substances, eg antibiotics, food
  • level of clinical supervision required


Disadvantages of mechanical treatment (Intermittent Pneumatic Compression and Graduated Elastic Compression Stockings):

  • discomfort/pain
  • uncomfortable to wear
  • range of sizes required
  • weight
  • external power source required, restricing patient's mobility (IPC)
  • poor compliance
  • expense
  • time and expertise required for fitting

"I am excited by the potential of this novel device to prevent significant adverse events in a high risk, high volume population".

According to the National Joint Registry over 150,000 lower limb arthroplasty procedures were carried out throughout the UK in 2008. Thromboembolic phenomena are a significant and common risk following these operations. DVT prophylaxis is by medical therapy and by prevention of blood stasis.

We are keen to examine the effect of the neuromuscular stimulator to lower the risk of post-operative DVT both directly and indirectly via increased ambulation.

"The geko™ device offers the potential for effective, affordable and convenient thromboprophylaxis".

Venous thromboembolism is an important, and largely preventable, problem in orthopaedic surgery. Mechanical methods are intuitively attractive as they can reduce the risk without introducing the alternative risk of bleeding that is associated with chemical methods. Existing mechanical methods rely on sequential or impulse compression. These devices are relatively cumbersome and expensive. Electrical stimulation showed encouraging results very many years ago and the technology warrants a revisit. The geko™device offers the potential for effective, affordable and convenient thromboprophylaxis.

"This technology has the potential to provide a paradigm shift in thrombosis prevention".
