Mechanical Thrombectomy using SOLITAIRE FR stent system
The Solitaire stent system from eV3 corp was initially designed for stent assisted coiling and off label in intracranial stenting for ICAD. However, The fully retreivable nature of the stent paved its path to be used as a thrombectomy device in acute stroke with large vessel occlusions. the manufacturers have now spilt the stent in two names: Solitaire AB for aneurysms and Solitaire FR for thrombectomy.
For thrombectomy, the stent has to be inserted and used in the regular way. But after waiting for few minnuted for flow restoration to occur, the stent and the delivery microcatheter are pulled out from the guide catheter. The clot get entangled in the wall of the stent and comes out along with it. Multiple repeated passes of the stent may be needed before obtaining a satisfactoy result. Thus in practice it works like any other thrombectomy device.
Below is a case demonstration of the same.
