The Tigertriever 17 Ultra Revascularization Device is intended to restore blood flow by removing thrombus from a large intracranial vessel in patients experiencing ischemic stroke within 8 hours of symptom onset. Patients who are ineligible for thrombolytic drug therapy or who failed thrombolytic drug therapy are candidates for treatment.

The Tigertriever 17 Ultra Revascularization Device (TRPP7266) is a line extension of the existing Tigertriever 17 Revascularization Device (TRPP7166) cleared under K203592. The Tigertriever 17 Ultra Revascularization 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. The Tigertriever 17 Ultra Revascularization Device is supplied sterile and is intended for single-use only by physicians trained in neurointerventional procedures and the treatment of ischemic stroke.
