Stryker’s Clot Retrieval Gizmo Remains Visible Throughout Procedure

In short

Stryker has announced the global commercial launch of the new Trevo® ProVue™ Retriever, the first clot removal device fully visible during the procedure for precise positioning within the clot and optimised clot retrieval in patients experiencing acute ischemic stroke. Watch the procedure on video here.

Background

We’ve covered the development of these clot retrieval devices quite a bit during the past several months, including here, when Stryker issued a favourable comparison between its Trevo® family of devices and their Merci retriever® predecessors.

The new device, with the noted addition of the eponymous “Vue” to its descriptor, possesses the additional feature of being visible to the operator during the deployment and retrieval process. Previous technology only provided visibility to the edges of the device.

Oregon Health & Science University (OHSU) was the institution where the first patient in the United States was treated using the Trevo® ProVue™ Retriever.

Physician comments

“Trevo ProVue Retriever’s full visibility provides a significant clinical benefit.” said Professor Liebig, M.D., Head of Neuroradiology, University Hospital of Cologne in Cologne, Germany. “I am impressed with how full device visibility provides more information during the procedure to quickly and easily position the device and enables real-time feedback for a new level of confidence to open blood vessels.”

“It is of great benefit to be able to see how a device interacts with the clot within the vessel, and may be able to demonstrate an underlying stenosis, as it did in the first patient we treated with the device,” said Gary Nesbit, M.D., Professor of Neuroradiology, Neurology, Neurosurgery, and the Dotter Interventional Institute at OHSU. “This gives me better information for clinical decisions and potentially increases the chance for better outcomes for my patients.”

Company comments

“Trevo ProVue represents our dedication to providing patients and physicians with the most advanced tools available to treat acute ischemic stroke,” said Mark Paul, President of Stryker’s Neurovascular division. “Trevo ProVue sets a new standard in stent retriever technology. It’s the first fully visible device allowing physicians to visualise placement, clot interaction and retrieval – that can make a big difference in patient treatment.”

Regulatory status

The device has been granted 510(k) market clearance by the U.S. Food and Drug Administration and is also available in international markets where it has been cleared for sale.
