Penumbra recently announced a significant update to its flagship large-bore reperfusion catheter, Red 72. Developed for speed and ease of navigation, the new Red 72 Silver Label features “meticulously blended” transition zones to better accommodate the natural distal anatomy of the brain, according to the company.
As per a recent Penumbra press release, the Red 72 Silver Label has been adapted from the Red 43 and Red 62 catheters, and features the company’s latest engineering enhancements.
The new Red 72 Silver Label with Sendit technology—a configuration intended to minimise the ledge effect, simplify preparation and make delivery easier—has shown a “remarkable” 50% increase in trackability over the original Red 72 with Sendit technology, the release adds.
“I had the opportunity to try the new Red 72 Silver Label during a recent procedure,” said Daniel Vela Duarte (Palm Beach Neuroscience Institute, West Palm Beach, USA). “The change and overall performance are radically better.”
The release goes on to state that the design of Red 72 reflects Penumbra’s commitment to the principles of Science-Based Aspiration Thrombectomy (S-BAT).
Red 72 was designed to occupy approximately 72–77% of the average M1 segment of the middle cerebral artery, which is within the optimal catheter-to-vessel inner diameter (ID) ratio to create a pressure differential necessary for an effective thrombectomy procedure, Penumbra claims. This innovative technology complements the Red 43 and Red 62 catheters, which are designed to support more distal vessels.
“Red 72 Silver Label tracked with ease to an M1 occlusion in a patient in their 90s with extreme cervical carotid tortuosity and underlying atherosclerotic disease,” Ian Kaminsky (Radiology Imaging Associates [RIA] Neurovascular, Englewood, USA) said after completing the first case with the catheter. “We are really looking forward to implementing this incredible technology into our practice.”
