Ultra Registry

Treat small aneurysms confidently

The ULTRA Registry is an investigator-initiated prospective, multicenter US registry of patients with small (≤5mm) intracranial aneurysms treated exclusively with Target Ultra and Nano Detachable Coils led by Dr. Gaurav Jindal at the University of Maryland.

Ultra Registry

The evidence is undeniable

At Stryker, our excellence is backed by evidence. When working in small intracranial aneurysms, the ULTRA Registry – an investigator initiated study involving 100 patients – showed that Target Ultra Detachable Coils and Target Nano Detachable Coils had zero coilrelated complications. For ruptured or unruptured aneurysms, Target Detachable Coils demonstrated safety and effectiveness—and the evidence proves it.
