The CEREGLIDE 42 Intermediate Catheter and the CEREGLIDE 57 Intermediate Catheter, with the Cerenovus Aspiration Tubing Set and a compatible aspiration pump, are indicated 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 thrombolytic drug therapy or who failed thrombolytic drug therapy are candidates for treatment. The Cerenovus Aspiration Tubing Set is intended to connect the Cerenovus Large Bore Catheter or the CEREGLIDE™ 71, 57 or 42 Intermediate Catheter of a compatible aspiration pump and to allow the user to control the fluid flow.

Both the CEREGLIDE ™ 42 Intermediate Catheter and CEREGLIDE ™ 57 Intermediate Catheter are variable stiffness, single lumen catheters designed to be introduced over a steerable guide wire or microcatheter into the neuro vasculature. The catheter shaft is composed of a stainless-steel variable pitch braid with a PTFE inner liner to facilitate movement of guide wires and other devices. The exterior of the catheter shaft is covered with polymer materials, which encapsulate the stainless-steel braid construction. The catheter has a stiff proximal shaft which transitions into the flexible distal shaft to facilitate the advancement of the catheter in the anatomy. The distal end of the catheter has a radiopaque marker band to facilitate fluoroscopic visualization and has a hydrophilic coating to provide lubricity to reduce friction during navigation in the vasculature. The proximal end of the catheter has a luer fitting located on the end of the catheter hub which can be used to attach accessories for flushing and aspiration. An ID band is placed at the distal end of the hub over a strain relief. The catheter is packaged with a Tuohy Borst Rotating Hemostasis Valve (RHV) with a side port and two slit introducers as accessories. The RHV with side port is used for flushing, insertion of catheters, and connection to an external aspiration system. The slit introducers are designed to introduce the catheter into the base catheter and protect the distal tip of the catheter during insertion into the RHV of the base catheter. The CEREGLIDE ™ 42 Intermediate Catheter and the CEREGLIDE ™ 57 Intermediate Catheter are designed for use in the removal of thrombus from the neurovasculature using continuous aspiration from an external vacuum source. The CEREGLIDE ™ 42 Intermediate Catheter and CEREGLIDE ™ 57 Intermediate Catheter are intended to be used with a compatible aspiration pump as a vacuum source that provides a minimum vacuum pressure of -68 kPa [-20 inHg] and a maximum vacuum pressure of -95 kPa [-28 inHg], and minimum 17 L/min flow rate, with a collection canister of at least 1000 mL volume. The CEREGLIDE ™ 42 Intermediate Catheter and the CEREGLIDE ™ 57 Intermediate Catheter are intended to be connected to the vacuum source using the Cerenovus Aspiration Tubing Set which is an externally manufactured tubing set with an internal diameter (ID) of 0.110" and overall length of 112", containing an integrated flow control switch.

The CEREGLIDE 92 Catheter System is indicated for use in facilitating the insertion and guidance of appropriately sized interventional devices into a selected blood vessel in the neurovascular system.

The CEREGLIDE™ 92 Catheter System consists of the CEREGLIDE™ 92 Intermediate Catheter and associated accessories, including the INNERGLIDE™ 9 Delivery Aid, Rotating Hemostasis Valve (RHV), and Slit Introducers. Intermediate Catheter: The CEREGLIDE™ 92 Intermediate Catheter is a single lumen, variable stiffness catheter designed to be introduced over a steerable guidewire along with a microcatheter and/or compatible support device into the neuro vasculature. The catheter consists of a lubricious PTFE lined inner lumen to facilitate movement of the guidewires and other devices, variable pitch stainless steel and tungsten braid, and various durometer polymer jackets. These jackets provide distal flexibility and gradually transition to a stiffer proximal shaft to facilitate the advancement of the catheter in the anatomy. The outer surface of the catheter is hydrophilic coated in order to reduce friction during manipulation in the vessel. A radiopaque marker at the distal end of the catheter provides fluoroscopic visualization of the catheter tip. The proximal end of the catheter incorporates a standard Luer adapter to facilitate the attachment of accessories, a hub, and an ID band. The CEREGLIDE™ 92 Catheter System is packaged with an INNERGLIDE™ 9 Delivery Aid, an RHV with a side port, and two Slit Introducer accessories. The INNERGLIDE™ 9 Delivery Aid is a compatible support device comprising of a single lumen catheter with a tapered tip, hydrophilic coating for increased lubricity, radiopaque tip for fluoroscopic visualization, and a proximal luer hub that is designed to be used as part of the CEREGLIDE™ 92 Catheter System to facilitate delivery of the CEREGLIDE™ 92 Intermediate Catheter to select blood vessels in the neurovasculature. The RHV with side port is used for flushing and insertion of catheters. The Slit Introducers are designed to introduce the CEREGLIDE™ 92 Intermediate Catheter into the base catheter and protect the distal tip of the CEREGLIDE™ 92 Intermediate Catheter during insertion into the hemostasis valve of the base catheter.
