The Rist™ 071 Radial Access Guide Catheter is indicated for the introduction of interventional devices into the peripheral, coronary, and neuro vasculature.

The Rist™ 071 Radial Access Guide Catheter is a single lumen, variable stiffness catheter with a stainless steel and nitinol reinforced shaft to provide support. The embedded stainless-steel flat wire cross coil is in the proximal section of the catheter, which transitions to a nitinol round wire single coil in the distal end. The catheter has a radiopaque platinum/iridium marker band on the distal end to aid in visualization. The distal 25 cm of the Rist™ 071 Radial Access Guide Catheter has a hydrophilic coating which reduces the insertion force and allows the catheter to traverse the vasculature more easily. The catheter has a nominal outer diameter of 0.084 inches and a nominal inner diameter of 0.071 inches. It is available in three working lengths: 95 cm, 100 cm, and 105 cm. The Rist™ 071 Radial Access Guide Catheter has a PTFE-lined lumen to reduce friction with other devices introduced through the lumen. It is intended to provide access to the target site via transradial access and, once in place, provides a reinforcing conduit for other intravascular devices. A radial access dilator is included as an accessory. The Rist™ 071 Radial Access Guide Catheter is supplied sterile, non-pyrogenic, and intended for single use only.

1. The Solitaire™ Revascularization Device is indicated for use to restore blood flow in the neurovasculature by removing thrombus for the treatment of acute ischemic stroke to reduce disability in patients with a persistent, proximal anterior circulation, large vessel occlusion, and smaller core infarcts who have first received intravenous tissue plasminogen activator (IV t-PA). Endovascular therapy with the device should be started within 6 hours of symptom onset. 2. The Solitaire™ Revascularization Device is indicated 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 IV t-PA or who fail IV t-PA therapy are candidates for treatment. 3. The Solitaire™ Revascularization Device is indicated for use to restore blood flow in the neurovasculature by removing thrombus for the treatment of acute ische to reduce disability in patients with a persistent, proximal anterior circulation, large vessel occlusion of the internal carotid artery (ICA) or middle cerebral artery (MCA)-M1 segments with smaller core infarcts (< 70 cc by CTA or MRA, < 25 cc by MR-DWI). Endovascular therapy with the device should start within 6-16 hours of time last seen well in patients who are ineligible for intravenous tissue plasminogen activator (IV t-PA) or who fail IV t-PA therapy.

The Solitaire™ Revascularization Device is designed to restore blood flow in patients experiencing ischemic stroke due to large intracranial vessel occlusion. The Solitaire™ Revascularization 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 distal nitinol portion of the Solitaire™ Revascularization Device facilitates clot retrieval and has Platinum/Iridium radiopaque markers on the proximal and distal ends and also features radiopaque markers along the circumference of the working length of the devices are supplied sterile and are intended for single-use only.

The Marathon™ Flow Directed Micro Catheter is intended to access the peripheral and neuro vasculature for the controlled selective infusion of physician-specified therapeutic agents such as embolization materials and of diagnostic materials such as contrast media.

The Marathon™ Flow Directed Micro Catheters are single-lumen, endhole catheters designed for the sub selective infusion of physician-specified therapeutic agents such as embolization materials and diagnostic materials such as contrast media in tortuous, distal vessels. The catheter has a semi-rigid proximal shaft and a highly flexible distal shaft to facilitate the advancement of the catheter in the anatomy. The proximal end of the catheter incorporates a standard luer adapter to facilitate the attachment of accessories. The catheter has a radiopaque marker at the distal end to facilitate fluoroscopic visualization. The outer surfaces of the catheter are coated to increase lubricity. Microcatheter may be used with stylet, guidewire or introducer sheath to increase the rigidity of the distal section during introduction into the guiding catheter.

The Riptide™ Aspiration System is intended for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (within the internal carotid, middle cerebral M1 and M2 segments, basilar, and vertebral arteries) 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 Riptide™ Aspiration System is composed of the following components: 1. React™ Catheters 2. Riptide™ Large Bore Aspiration Tubing 3. Riptide™ Aspiration Pump 4. RiptideTM Collection Canister with Intermediate Tubing No changes were made to the catheters, tubing or collection canister with intermediate tubing cleared in the predicate system under K172448 and, most recently, under K183185. The Riptide™ Aspiration Pump is designed to generate vacuum for the Riptide Aspiration System. The vacuum pressure of the Riptide Aspiration Pump is set by turning the vacuum control valve until the vacuum gauge reads a minimum of 20inHg but not exceeding 25inHg. The Riptide Aspiration Pump is reusable, non-sterile, and intended to be utilized outside of the sterile environment.

The Hydrophilic Guidewire is indicated for general intravascular use to aid in the selective placement of catheters in the peripheral, visceral and cerebral vasculature during diagnostic and/or therapeutic procedures.

The Hydrophilic Guidewire is a stainless-steel guidewire with a radiopaque, platinum distal coil. The guidewire has a hydrophilic coating that spans the distal 170 cm. Included within the sterile pouch is a pin vise to assist in guidewire manipulation and an introducer needle to ease the introduction of the guidewire into the catheter hub and/or hemostasis valve.
