Imperative Care introduces ischaemic stroke treatment catheter

Imperative Care has launched the Zoom 4S catheter, an advanced thrombectomy device for treating ischaemic stroke.

Marking the latest addition to its Zoom Stroke System, the new catheter aims to expand access to the ADAPT 2.0 technique. It aims to address a broader range of patient anatomies during aspiration thrombectomy procedures.

It is designed to simplify stroke thrombectomy by reducing device exchanges and introducing a single setup approach.

The ADAPT 2.0 technique, central to this advancement, involves positioning an intracranial 0.088in catheter closer to the clot and utilising an asymmetric tip design for targeted aspiration.

The system applies Continuous Dual AspiraTion (CDAT) through two catheters for enhanced clot ingestion.

First published in 2014, the original ADAPT technique showed the clinical benefits of direct aspiration as a frontline treatment for acute ischaemic stroke.

Expanding on this groundwork, Imperative Care has advanced the method with ADAPT 2.0, emphasising rapid thrombectomy procedures that do not require several device exchanges.

Imperative Care chief technology officer Richard Leparmentier said: “At Imperative Care, we believe that it is our responsibility to bring the most advanced technologies to market, with the goal of improving patient outcomes by shaping the arc of innovation in stroke care.

“With a focus on reducing treatment times and streamlining stroke procedures, we have purposefully engineered one simple Zoom setup to bring the key procedural benefits of the ADAPT 2.0 technique to more patients.

“With the introduction of Zoom 4S, Imperative Care is heralding this new chapter of stroke care, as we believe this combination of technologies will provide physicians with the confidence to effectively address a broad range of clot locations using a single setup.”

The complete Zoom Stroke System includes catheters such as Zoom 35, 4S, 45, 55, 71 and 7X; as well as the Zoom 88 Large Distal Platform and Zoom 88 Support.

In September 2025, Imperative Care received 510(k) clearance from the US Food and Drug Administration (FDA) for its Symphony thrombectomy system, which is designed to treat pulmonary embolism (PE).
