Intended Use

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.

Device Story

The CEREGLIDE 92 Catheter System is a neurovascular intervention tool used by physicians to navigate blood vessels. It consists of an intermediate catheter, an INNERGLIDE 9 delivery aid, a rotating hemostasis valve (RHV), and slit introducers. The system is introduced over a steerable guidewire. The intermediate catheter features variable stiffness, a PTFE-lined lumen, and a hydrophilic coating to reduce friction. The INNERGLIDE 9 delivery aid facilitates the delivery of the intermediate catheter to the target vessel. The device is used in a clinical setting under fluoroscopic guidance, enabled by radiopaque markers on the catheter and delivery aid. The system allows for the delivery of other interventional devices, aiding in neurovascular procedures. The device is single-use and sterile.

Clinical Evidence

No clinical data. Substantial equivalence is supported by bench testing, including design verification (visual inspection, dimensional analysis, leak resistance, tensile strength, particulate count, coating durability, kink resistance, torque performance, trackability, burst pressure) and in vitro usability studies in a neurovascular model.

Technological Characteristics

Variable stiffness single-lumen catheter; materials include PTFE (liner), stainless steel/tungsten (braid/marker), Pebax, Urethane, Nylon, Makrolon, Vestamid (jackets/hubs). Hydrophilic coating. Sterilized via 100% Ethylene Oxide (ISO 11135). Complies with ISO 10555-1, ISO 80369-7, and ISO 10993-1. No software or electronic components.

Indications for Use

Indicated for facilitating insertion and guidance of interventional devices into neurovascular blood vessels. No specific patient population or contraindications defined.

Regulatory Classification

Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.

### V. Device Description

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

#### Based upon the intended use, design, materials, function, performance testing and IX. Conclusion biocompatibility testing, it is concluded that the subject device, CEREGLIDE™ 92 Catheter System (K233982) is substantially equivalent to the predicate CEREGLIDE™ 92 Intermediate Catheter (K230726). The addition of the INNERGLIDE™ 9 Delivery Aid did not raise any new questions regarding the safety and effectiveness of the device. The CEREGLIDE™ 92 Catheter System, as designed, manufactured, packaged, and sterilized, is substantially equivalent to the predicate device currently marketed under the Federal Food, Drug and Cosmetic Act.
