The geko™ device for VTE prophylaxis - serving an unmet need in high-risk acute stroke patients

Current UK practice for DVT prophylaxis in acute stroke patients is based upon data from the CLOTS 3 study and usually comprises of Intermittent Pneumatic Compression (IPC) or a prophylactic-dose of Low Molecular Weight Heparin (LMWH) when the bleed risk is reduced1. However, regardless of these interventions, a small group of patients remain contraindicated to these therapies leaving them exposed to developing a DVT or PE.

 

Firstkind Ltd, a UK based medical devices company, is working with an NHS Trust to introduce the innovative geko™ device into the acute stroke pathway, when patients are unsuitable for drug prophylaxis and/or contraindicated to IPC.

 

The geko™ is a battery powered, disposable, neuromuscular electrostimulation device designed to increase blood flow in the deep veins of the leg2. The geko™ gently stimulates the common peroneal nerve activating the calf and foot muscle pumps increasing venous, arterial and microcirculatory blood flow. The blood flow increase is equal to 60%3 of walking without a patient having to move or exert energy.  

 

Patient compliance and the geko™ anti-stasis capability is being assessed through a prospective audit of clinical practice, covering patients who have been admitted for either ischemic or haemorrhagic stroke4. Patients unsuitable for VTE drug prophylaxis or contraindicated to IPC are being given the geko™ device.  

Interim analysis highlights that the majority of high risk immobile acute stroke patients who could not tolerate IPC are able to tolerate the geko™. These patients would have not been treated as effectively otherwise, with the potential that geko™ will reduce the risk of morbidity and mortality in stroke patients.
