Hēlo® Thrombectomy System
Advanced dual-action technology for effective clot removal

“This technology represents the marriage between large and small-bore embolectomy, which allows for operators to travel through the heart with a smaller catheter but expand a larger funnel that matches the clot engagement of large-bore catheters – leaving a smaller footprint and lowering the risk of hemodynamic impact for the patient.”

Single Pass Perfomance
Effective clot removal, steerable, low profile
RESHAPING CLOT REMOVAL
The Hēlo® Thrombectomy System is designed to effectively engage, remodel, and remove thrombus in patients with venous thromboembolism. Its unique atraumatic funnel design and dual-action technology facilitate large-bore clot capture while maintaining a low-profile system for controlled clot removal, enabling single-pass PE treatment.
UNIQUE FUNNEL DESIGN
Self-expanding, atraumatic funnel design ensures wide distal opening for effective large bore clot engagement


DUAL-ACTION TECHNOLOGY
Small profile system remodels and removes clot through combined high-speed agitation and simultaneous physician-controlled aspiration.

ENGINEERED FOR CONTROL
The Hēlo® Thrombectomy System is engineered to put control in the physician’s hands, enabling precise navigation, low-profile heart crossing, controlled clot engagement, and real-time procedural insight.

ADVANCED NAVIGATION
PRIMARY & SECONDARY CURVES ENABLE WIRELESS NAVIGATION
Fixed primary and rotating secondary curves facilitate steerable, wireless navigation through vasculature.
LOW PROFILE
15F HEART CROSSING PROFILE
Low-profile design enables controlled crossing through the right heart.
EFFECTIVE MECHANISM OF ACTION
24F CLOT ENGAGEMENT & ORBITAL CLOT REMODELING
Designed to engage, remodel, and remove thrombus for effective clot clearance.
INTEGRATED FEEDBACK
REAL-TIME VISUALIZATION & PRESSURE MONITORING
Integrated flushing port supports contrast injection for real-time flow visualization and pressure monitoring.
Near Zero Blood Loss
With the Hēlo® Blood Return System
EFFICIENT BLOOD RETURN FOR COMPLETENESS
Pulmonary embolism procedures should be defined by effective clot removal, not limited by blood loss. The Hēlo® Blood Return System enables physicians to return high-quality blood to the patient through a streamlined return process, providing the control to end the procedure when treatment is complete.
HĒLO® RETURN
Streamlined, single-operator blood return system with integrated clot filtration and dual 40-micron blood filters enables high-quality blood return for procedural completeness.
Audible Flow Indicator
Provides real-time feedback during aspiration helping mitigate blood loss during thrombectomy.
