Syntra Origami Technology
Syntra is a novel adjunctive therapy for Wide Neck Sidewall, Bifurcation & various Irregular Aneurysms (ruptured & unruptured). It is an intrasaccular device that provides a 3D endo-skeleton enabling a stable scaffold implant for embolization in wide neck aneurysm scenarios enabled to navigate tortuous vasculature with acute angulations that presents challenging scenarios for the user/operator (i.e. Ophthalmic ICA sidewall & bifurcation IA's). It is intended to be used in conjunction with bare platinum coils in the treatment of intracranial aneurysms without the need for Anti-Platelet drugs. The device is delivered with an integrated mechanical detachment system with no external accessories. Syntra embolization device requires the use of a single microcatheter-only to treat typical cerebral aneurysms (saccular & non-saccular).
