The Solitaire™ 2 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 intravenous tissue plasminogen activator (IV t-PA) or who fail IV t-PA therapy are candidates for treatment.

The Solitaire™ 2 device is designed to restore blood flow in subjects experiencing ischemic stroke due to large intracranial vessel occlusion within 8 hours of symptom onset. It is indicated for subjects who are ineligible for intravenous tissue plasminogen activator (IV t-PA) or who fail IV t-PA therapy. The distal nitinol portion of the device facilitates clot retrieval and has Pt-Ir radiopaque markers on the proximal and distal ends. The following modifications have been made to the device in support of this application: • The attachment zone has been redesigned for greater tensile strength. • The marker band has been redesigned to aid the crimping process. • The pushwire now contains a fluorosafe marker. • The Solitaire™ 2 Device uses one piece of PTFE tubing.

The Solitaire™ FR 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 intravenous tissue plasminogen activator (IV t-PA) or who fail IV t-PA therapy are candidates for treatment.

The Solitaire™ FR 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 intravenous tissue plasminogen activator (IV t-PA) or who fail IV t-PA therapy are candidates for treatment. The device is intended for use in the neurovasculature such as the internal carotid artery, M1 and M2 segments of the middle cerebral artery, basilar, and the vertebral arteries. The device is a nitinol self-expanding, fully retrievable, stent-based design that allows for clot retrieval when deployed in occluded target vessels after acute ischemic stroke. The distal nitinol portion of the device facilitates clot retrieval and has Pt-Ir radiopaque markers for visualization on the proximal and distal ends. The device is supplied sterile and is intended for single-use only by physicians trained in interventional neuroradiology and treatment of ischemic stroke.

The ev3 Occlusion Balloon Catheters are indicated for use in blood vessels of the peripheral and neuro vasculature where temporary occlusion is desired. These catheters offer a selective technique of temporary vascular occlusion, which is useful in selectively stopping blood flow in a vessel. The ev3 Occlusion Balloon Catheters may also be used in balloonassisted embolization of intracranial aneurysms.

The ev3 Occlusion Balloon Catheters are single lumen, open-ended balloon catheters designed for advancement into the vasculature over a 0.010" guidewire. Balloon inflation is accomplished by advancement of the guidewire through the open distal end of the balloon, redirecting inflation media to the balloon through side holes in the catheter wall. The Occlusion Balloon Catheters are available in diameters ranging from 3 to 7 mm and lengths ranging from 7 to 30 mm. The devices are packaged in a sterile pouch and are intended for single use only.
