EkoSonic™ Endovascular System
The most studied device in the space.
Ekos has been shown to yield safe and effective results for acute, massive (high risk) and submassive (intermediate risk) PE. It improves right ventricularfunction and pulmonary artery pressure while minimizing the risk of bleeding.1
- Reduces RV/LV ratio by more than 23% on average in as little as 2 hours8
- Reduces PA pressures by 28% (at 48 hours)5
- 76% less thrombolytic drug dosage than standard treatment5
- Minimized risk of bleeding1
In the Seattle II study of 150 patients with massive or acute intermediate-risk PE using an Ekos and lytic combination, the mean RV/LV ratio decreased from 1.55 pre-procedure to 1.13 at 48 hours post-procedure (-<0.0001) while PA systolic pressure decreased from 51.4mmHg to 36.9mmHg (P<0.0001). In contrast to the 2.5-3% rate of intracranial hemormaging associated with historical systemic fibrinolysis and full-dose tPA, no patients in this study experienced intracranial bleeding or fatal bleeding events.7
In the OPTALYSE PE study of 101 patients with submassive PE utilizing Ekos therapy, each of the OPTALYSE 2, 4 & 6 hr cohorts reduced RV/LV ratio by 23-26%. Total tPA doses in the study ranged from 8-24 mgs bilaterally and the bleeding rate was a very low 3%. The one-year data demonstrated a 2% mortality rate - significantly below both anticoagulation and systemic therapy.16,17
Deep Vein Thrombosis
The EkoSonic Endovascular System quickly restores blood flow,potentially reducing the risk of pulmonary embolism andpost-thrombotic syndrome (PTS).
- Up to 50% of DVT patients have PE6
- Removes thrombus more completely compared to CDT3
- Reduces post-thrombotic syndrome7
The EkoSonic Endovascular System improves on standard CDT by safelyaccelerating drug penetration, even in difficult-to-reach areas:
- Shorter treatment times2
- Shorter treatment times2
- Lower 30-day amputation rate2
- Lower bleeding rates when compared to CDT2
- Higher complete dissolution rate of thrombus2
- Shorter hospital stays2
