Stent retrievers
Solitaire X
A device intended to be percutaneously introduced into the vasculature (coronary, peripheral and/or intracranial) through an appropriate intravascular catheter for the removal of clotted blood (i.e., a thrombus or thromboembolus) or other formed elements causing vascular obstruction; revascularization may also be achieved through thrombus reorientation. Also referred to as a stent retriever or clot retrieval catheter, it consists of an expanding, stent-like wire net connected to a pusher wire primarily intended to grip and remove the emboli/thrombi; it might include a guide-catheter dedicated to introduction of the wire-net. This is a single-use device.
