DEVICE DESCRIPTIONThe Surpass Flow Diverter System is comprised of a self-expandable braided device preloaded in a Delivery Catheter.The Surpass Flow Diverter System consists of the following components:• Surpass Flow Diverter• Surpass Delivery Catheter• PusherThe Surpass Flow Diverter is preloaded onto the Pusher which in turn is locked in place within the Delivery Catheter via a Y-Valve/Rotating Hemostatic Valve (RHV). Each device is shipped sterile and labeled for single use only.
INTENDED USE/INDICATIONS FOR USE The Surpass Flow Diverter is indicated for use for the treatment of saccular or fusiform intracranial aneurysms arising from a parent vessel with a diameter of ≥2 mm and ≤5.3 mm.
CONTRAINDICATIONS Intracranial artery stenting is generally contraindicated in the following patient types: • Patients in whom the parent vessel size does not fall
within the indicated range.• Patients in whom antiplatelet and / or
anticoagulation therapy (aspirin and clopidogrel) is contraindicated.
• Patients who have not received dual anti-platelet agents prior to the procedure.
• Patients with an active bacterial infection.• Patients in whom the angiography demonstrates
the anatomy is not appropriate for endovascular treatment, due to conditions such as:
– Severe intracranial vessel tortuosity or stenoses – Intracranial vasospasm not responsive to medical therapy
WARNINGS• The procedure should be carried out under the
direction of personnel with the requisite interventional training, especially intracranial stent procedures. Appropriate facilities should be available for managing the potential complications of the procedure.
• Complications may occur without warning. At all times a fully equipped emergency cart and resuscitation equipment should be readily available, and personnel competent in recognizing and treating complications of any severity should be on hand.
• Do not use if the inner package is opened or damaged.
• The system is designed to be manipulated while under high-quality fluoroscopic observation. If resistance is met during manipulation, determine the cause of resistance before proceeding.
• Do not torque or rotate the System.• Purge the entire Surpass Delivery System carefully to
avoid the accidental introduction of air into the system.• Ensure optimal positioning of the Surpass Flow
Diverter prior to deployment. Once deployment is initiated, the Surpass Flow Diverter cannot be resheathed or recaptured.
PRECAUTIONS• Experience with device implants indicates that there
is a risk of stenosis. Subsequent stenosis may require dilatation of the vessel segment containing the device. The risks and long-term outcome following dilatation of endothelialized devices is unknown at present.
• Confirm the device labeling reflects the desired size of the target vessel where the device is to be used.
• Do not expose the system to organic solvents (e.g., alcohol).
• Appropriate anti-platelet and anti-coagulation therapy should be employed in accordance with standard medical practice.
• A thrombosing aneurysm may aggravate pre-existing or cause new symptoms of mass effect and may require medical therapy.
• Use product prior to the “Use By” date.• The ability of the device to withstand balloon post-
dilatation has not been established.• Do not remove the Surpass Flow Diverter from its
Delivery Catheter. The device and delivery catheter are intended to perform as a single system and must not be altered.
• Carefully inspect the device packaging and system prior to use. Do not use the Surpass Flow Diverter if any component appears damaged or missing.
• Do not pull up on the Pusher when removing the Surpass Delivery System from its tray. Instead hold the Delivery System by its RHV and hoop to facilitate removal from the tray.
• Select a device length that is at least 10 mm longer than the aneurysm neck to maintain a minimum of 5 mm on either side of aneurysm neck.
• Do not attempt to move the Surpass Flow Diverter more distally once it has begun to appose the vessel walls.
• Use caution when crossing the deployed device with guidewires or other accessory devices.
• Dispose of all used devices in accordance with hospital policy for biohazardous materials.
ADVERSE EVENTSRisks that may be associated with the use of the Surpass Flow Diverter System in the intracranial arteries include:• Aneurysm recanalization• Aneurysm enlargement• Allergic reaction including, but not limited to,
contrast, cobalt chromium or platinum tungsten metal, and medications
• Arrhythmia• Arteriovenous fistula• Confusion, coma, loss of consciousness or other
change in mental status• Death• Detachment of a component of the system• Emboli (air, tissue or thrombotic emboli)• Emergent neurosurgery• Failure to deliver the device to the intended site• Headache• Hemorrhage (including intracranial, vascular,
peritoneal, and groin)• Hematoma• Hypotension / Hypertension• Hydrocephalous• Incomplete Aneurysm Occlusion• Infection• Injury to normal vessels or tissue• Ischemia• Occlusion of side branch• Mass effect• Myocardial infarction• Nausea• Neurologic deficit• Pain at insertion site• Perforation of aneurysm• Pseudoaneurysm• Reactions due to radiation exposure• Renal failure• Rupture, vessel or aneurysm• Seizures• Stenosis of treated segment• Device migration / embolization• Device thrombosis / occlusion• Stroke /TIA/ cerebrovascular accident – new or
worsening of symptoms• Total occlusion of treated segment• Vasospasm• Vessel dissection or perforation• Vessel thrombosis/occlusion• Visual impairment/blindess• Vomiting

Consistency Matters
Stroke: Our Only Focus. Our Ongoing Promise.
Consistent...OCCLUSIONThe number of braid wires increases with the device diameter, maintaining consistent mesh density for increased efficacy. Maintaining consistent mesh density may lead to faster aneurysm occlusion.
COVERAGELonger device lengths offered across multiple diameters, designed to effectively bridge wide-necked aneurysms and reduce the need for multiple devices.
DEPLOYMENTCustomized over-the-wire delivery system improves device delivery and detachment.
Higher Mesh Density. Consistent Occlusion.
Unique preloaded delivery system. Consistent Deployment.

The SurpassTM Flow Diverter comes preloaded onto its own microcatheter.
The pusher is housed in the delivery catheter and pushes the Surpass Flow Diverter
out of the catheter and into the parent artery. The pusher stabilizes the position of
the Surpass Flow Diverter in the delivery catheter.
