Imperative Care has introduced a new component to its Zoom Stroke System, enabling simultaneous use of two aspiration catheters through a single vacuum source for ischemic stroke treatment.
The Zoom DuoPort, which supports the continuous dual aspiration technique (CDAT), is now in clinical use, with the first procedures performed using the newly integrated system.
The CDAT configuration, designed for use within the sterile field, connects two Zoom PODs to a single aspiration source. This setup is intended to enhance physician control over clot removal procedures by delivering continuous aspiration with immediate procedural feedback.
The technology builds on the Zoom Stroke System’s existing capabilities and extends the functionality of the Zoom 88 and Zoom 71 catheters.
In January 2025, Imperative Care received clearance from the US Food and Drug Administration (FDA) for its updated Zoom Stroke System under the 510(k) framework. The clearance covers the use of large-bore .088” catheters for both vascular access and clot aspiration when deployed alongside a Zoom catheter.
Supporting data from the company’s Imperative Trial demonstrated that dual aspiration using the Zoom platform is efficient and safe across a variety of vascular anatomies.
Imperative Care EVP and stroke business GM Ariel Sutton said: “The launch of CDAT and Zoom DuoPort is the result of our direct partnership with physicians who participated in the Imperative Trial and provided feedback on the need to make their procedures more efficient when applying aspiration to two Zoom catheters at the same time.
“We have introduced a full-system approach, starting with arch access and .088” intracranial access, through complete clot ingestion with asymmetric aspiration. Now, the CDAT approach allows physicians to achieve the benefits of our full system using dual aspiration.”
In one of the initial uses of the new configuration, a patient presenting with a terminal internal carotid artery (ICA) occlusion was treated at Oklahoma University Health in Oklahoma City.
The intervention utilised the Zoom VTK Insert Catheter for vessel selection, followed by the use of Zoom 88 for access. The procedure employed both Zoom 88 and Zoom 71 catheters to maintain continuous aspiration via the DuoPort interface.
According to procedural data, the clot was retrieved in a single pass, achieving TICI 3 revascularisation with the clot captured in the Zoom 88 catheter.
The Zoom Stroke System comprises multiple access and aspiration tools designed for use across the full thrombectomy workflow, from initial vascular entry to reperfusion.
Key components of the system include the Zoom 35, 45, 55, and 71 catheters, Zoom 88 and Zoom 88 Support, Zoom POD, Zoom Pump, and Zoom DuoPort. Additional accessories include the Zoom 6F Insert Catheters and the Zoom RDL Radial Access Platform.
All catheters in the Zoom portfolio incorporate the proprietary TRX Tip technology, which provides an expanded clot engagement surface. This design feature is intended to facilitate more consistent clot interaction and smoother navigation through complex vascular pathways.
