Perflow Medical has announced the issuance of US Patent No. 9510855, by the US Patent and Trademark Office (USPTO), for the Stream Dynamic Neuro-Thrombectomy Net. According to the company, this is the first device to provide full dynamic wall apposition during the treatment of acute ischaemic stroke.

With more than 13.5 million annual occurrences worldwide, stroke is the primary cause of long-term disability with a devastating effect on patient quality of life and long-term healthcare costs. Neuro-thrombectomy devices have shown promise to improve patient outcomes but many commercial devices restrict device manipulation, hindering the physician’s ability to provide complete reperfusion.

Perflow Medical says that the Stream Net provides physicians’ full control of the radiopaque, braided net to make real-time adjustments based on intracranial vessel geometry. Physicians can manipulate the net diameter, length, and radial force to optimise contact with the vessel wall and improve clot retention during removal through tortuous anatomy.

“Timely revascularisation is crucial for treating patients with acute ischaemic stroke, however the cases remain inherently challenging,” comments Danny Farin, CEO, Perflow Medical. “We believe better patient outcomes are achieved by leveraging the physician’s expertise and experience. Our propriety braided net platform provides physicians with superior control and full dynamic wall apposition to address clinical situations real-time. We are excited to offer the Stream Net to help patients in Europe.”

The Stream Dynamic Neuro-Thrombectomy Net is approved in Europe for the endovascular treatment of acute ischaemic stroke.
