The Tigertriever device is a stentriever that is comprised of an adjustable nitinol braided mesh, stainless steel shaft, nitinol core wire and a handle. The shaft connects the mesh and the handle by the core wire that runs inside the shaft from the distal end of the mesh to the slider activation element in the handle. The mesh is expanded when the physician pulls the slider, since the wires of the mesh are completely radiopaque, the physician sees the mesh under fluoroscopy and controls it until it conforms to the vessel diameter. The design of the wire mesh is optimized to penetrate the clot and encapsulate it during retrieval. Two versions of the device are available. The standard version Tigertriever (TRPP7155) has a net length of 32mm (unexpanded form) and it is delivered through a microcatheter with an internal diameter of 0.021 inches. The shorter version Tigertriever 17 (TRPP7166) has a net length of 23 mm (unexpanded form) and it is delivered through a microcatheter with an internal diameter of 0.017 inches. The Tigertriever is provided with a 3.5 Fr peelable loading sheath.
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.
