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 sterile flexible tube designed for the percutaneous, transluminal disruption and removal of clotted blood (i.e., a thrombus or thromboembolus) or other formed elements causing vascular obstruction in native and stented blood vessels, native and synthetic bypass grafts, and/or haemodialysis access grafts, through suction (aspiration) typically achieved with the use of an included syringe(s) attached to the proximal end of the catheter, or connection to a dedicated suction pump system. Collection baskets may also be included to obtain filtered blood specimens for analyses. This is a single-use device.
