The EKOS Endovascular Device was cleared by the FDA via the 510(k) pathway on April 20, 2022. It is manufactured by Boston Scientific and classified as a Class 2 device.
What It Is
The EKOS Endovascular Device is a catheter-based system designed to enhance thrombolysis through ultrasound assistance. It is intended for use in the treatment of venous thromboembolic conditions, facilitating the breakdown of blood clots.
Clinical Applications
Commonly used in the management of pulmonary embolism and deep vein thrombosis, the device is applied in scenarios where rapid clot dissolution is necessary, especially when systemic thrombolysis is contraindicated.
Evidence Summary
The literature includes 15 studies, comprising RCTs, prospective, and retrospective analyses, published between 2022 and 2025. These studies explore the device's efficacy and safety in various thromboembolic conditions.
Reported Outcomes
Published studies report that the EKOS Endovascular Device is effective in enhancing thrombolysis, particularly in pulmonary embolism cases. Outcomes include improved rates of clot resolution and limb salvage, with some studies noting sex-based differences in efficacy.
Safety Profile
Reported complications include bleeding events and potential device-related adverse effects. However, the overall safety profile is considered favorable in comparison to systemic thrombolysis.
Evidence Limitations
Evidence gaps include a need for larger, long-term studies to better understand the device's efficacy across diverse patient populations. Current studies often have limited sample sizes and short follow-up durations.
