The capital will expedite E2’s focus on developing solutions for pulmonary embolism (PE), as the company nears completion of enrolment in its prospective multicentre ENGULF pivotal trial.

This FDA-approved trial is assessing the Hēlo PE thrombectomy system’s feasibility, efficacy, and safety for PE treatment.

Featuring a patented dual-action mechanism that combines aspiration with mechanical clot disruption, the system’s “large-bore” performance is delivered through a small-profile catheter, which is expected to enable single-pass procedures.

The Hēlo PE system is currently intended solely for investigational purposes and has not received approval for commercial use.

E2 is focused on developing and deploying solutions for clot removal. Its technology platform mainly targets the intricate challenges associated with VTE intervention.
