The MegaVac Thrombectomy System is a single-use intravascular mechanical thrombectomy and aspiration system including a ThromboWire containing an embolectomy element. The MegaVac Catheter’s SafeSealTM technology utilizes a distal silicone coated nitinol braid that expands to temporarily occlude antegrade blood flow. The catheter body has inner and outer coaxial shafts that expand the braid, temporarily occluding the vessel and allowing for aspiration. The proximal handle assembly actuates the SafeSeal funnel. The ThromboWire consists of a nitinol embolectomy element that when expanded by the proximal actuation handle, can serve to pull matter towards the MegaVac catheter.
A device intended to be percutaneously introduced into the vasculature (coronary, peripheral and/or intracranial) through an appropriate intravascular catheter (not included) for the removal of clotted blood (i.e., a thrombus or thromboembolus) or other formed elements causing vascular obstruction. Also referred to as a stent retriever, it consists of an expanding, stent-like wire net connected to a pusher wire primarily intended to grip and remove the emboli/thrombi; in some cases revascularization may be achieved through thrombus reorientation. This is a single-use device.
