Jan. 28, 2026 — Imperative Care has announced the commercial launch and first patient cases of the new Zoom 4S Catheter — an advanced aspiration thrombectomy device representing the company’s latest innovation in ischemic stroke treatment.
The Zoom 4S Catheter was built for ease of use, empowering physicians with a device that is designed to navigate a broad range of patient anatomies. The Zoom 4S Catheter brings the benefits of the ADAPT 2.0 technique to more patients — further strengthening the company’s aim at systematization of stroke treatment. The Zoom Stroke System, now enhanced with Zoom 4S, is engineered to simplify stroke thrombectomy procedures by reducing the number of device exchanges.
The ADAPT 2.0 technique, which leverages the unique benefits of the Zoom Stroke System, was created to bring:
- An intracranial 0.088” catheter closer to the clot
- Aspiration through an asymmetric tip catheter with the goal of more complete clot ingestion
- The enhanced power of aspiration through Continuous Dual AspiraTion (CDAT) applied to two catheters
The original ADAPT technique, initially studied and published in 20141, transformed stroke thrombectomy by demonstrating the clinical value of direct aspiration as a frontline treatment method to achieve excellent clinical and angiographic outcomes with efficiency and ease of use2. Building on the foundation of ADAPT, innovations ushered in by Imperative Care have evolved this technique to ADAPT 2.0, designed for fast, simple and effective treatment of stroke, without requiring multiple exchanges. The addition of Zoom 4S enhances this capability with a single setup that is intended to simplify the procedure.
“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,” said Richard Leparmentier, Chief Technology Officer of Imperative Care.
Dr. Chip Wiginton, D.O., Prisma Health Greenville Memorial Hospital, said: “In my early experience with Zoom 4S, I have found that it integrates seamlessly within the Zoom Stroke System, helping reduce guesswork when selecting the optimal device set-up for each patient’s anatomy. Zoom 4S also provides a purposefully designed option for employing the ADAPT 2.0 technique, offering me procedural control through a stable platform for intracranial access, reliable clot ingestion using asymmetric aspiration, and continuous dual aspiration applied to both Zoom 7X and Zoom 4S catheters. We look forward to further understanding the potential impact of this system in helping make stroke procedures faster and simpler.”
All Zoom Catheters are designed with an asymmetric tip, which has been shown to provide 15% greater clot engagement area at the tip of the catheter, relative to a traditional flat-tip catheter,3 and are constructed to enable smooth tracking through challenging vasculature.
