Intended Use

The LiquID Guide Catheter Extension is intended to be used in conjunction with guide catheters to access discrete regions of the coronary and/or peripheral vasculature, and to facilitate placement of interventional devices.

Device Story

LiquID Guide Catheter Extension is a percutaneous catheter used in conjunction with conventional guide catheters to access coronary and peripheral vasculature. It facilitates the delivery of interventional devices by providing deeper vascular intubation and enhanced support. The device consists of a 150 cm proximal stainless-steel shaft and a 15 cm single-lumen distal shaft. It is operated by physicians in a clinical setting. The device is advanced through a guide catheter; its distal end extends beyond the guide catheter tip to reach target anatomy. The output is the provision of a stable conduit for interventional tools. Benefits include improved access to discrete vascular regions and easier placement of interventional devices. The device features a larger intraluminal diameter compared to predicates, with models (061 and 071) sized for 6F and 7F guide catheters.

Clinical Evidence

Bench testing only. Verification testing included shaft marker visibility, dimensional accuracy, functionality with hemostasis valves, trackability, contrast injection, compatibility with interventional devices, radiopacity, kink resistance, flexibility, tensile/torsional strength, burst pressure, corrosion resistance, coating durability, and particulate evaluation. Biocompatibility testing was performed per ISO 10993-1 (cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemolysis, complement activation, thrombogenicity). Sterilization validated to SAL 10^-6 per ISO 11135.

Technological Characteristics

Distal shaft: PTFE liner, MP35N coil with tantalum core, nylon-based encapsulation, Pebax/PTFE atraumatic tip. Proximal shaft: 0.018" stainless-steel. Lubricity: Silicone fluid coating. Radiopacity: Tantalum core. Sterilization: Ethylene oxide (EO). Connectivity: None (mechanical device).

Indications for Use

Indicated for patients requiring coronary or peripheral vascular access to facilitate the placement of interventional devices.

### Reference Devices:

The Seigla Medical Liquid Guide Catheter Extension is substantially equivalent in intended use, method of operation and technical aspects to the following predicate devices:

Primarv Predicate: K172090 - Vascular Solutions/Teleflex Guideliner V3 Catheters

Additional Reference Devices: K163314 - Boston Scientific Guidezilla II Guide Extension Catheter K183353 - Medtronic Telescope Guide Extension Catheter K160561 - OX Medical Boosting Catheter

### Summary Description:

The LiquID device is a guide catheter extension that is substantially equivalent to currently marketed devices with the distinction of having a larger intraluminal diameter. The device is available in two models: Liquid 061 and LiquID 071 which are designed to fit within 6F and 7F conventional guide catheters, respectively. The device has a 150 cm working length and a 0.018" diameter proximal stainless-steel shaft connected to a 15cm single lumen distal shaft (exchange length).

The LiquID device distal shaft includes an internal PTFE liner, a MP35N coil internally clad with a tantalum core for support and radiopacity, and an exterior nylon-based encapsulation layer. The rounded and atraumatic distal tip includes PTFE and Pebax that is monolithically attached (no joints) to the distal shaft. The distal shaft exterior is wiped with silicone fluid for lubricity.

{4}------------------------------------------------

The transition between the single lumen distal shaft and proximal shaft includes a stainless collar that is welded to the proximal shaft, positioned over the PTFE liner, and encapsulated in polymer. This construction provides a smooth transition and structural integrity.

The LiquID device has proximal positioning marks (laser created oxide marks) that are approximately 95cm and 105cm from the distal tip and has a colored proximal handle that follows the coronary guide catheter size color code. The proximal shaft is not coated.

The LiguID device is packaged in a HDPE hoop within a Tyvek poly sealed pouch. The pouch is contained in an SBS shelf box. Twenty-five (25) shelf boxes are contained within a shipping container. The shipping containers are used for transporting the devices between the manufacturer, the ethylene oxide (EO) sterilization contractor, and the distribution locations.

# Indication for Use:

The LiquID Guide Catheter Extension is intended to be used in conjunction with guide catheters to access discrete regions of the coronary and/or peripheral vasculature, and to facilitate placement of interventional devices.

## Comparison to Predicate Devices:

The LiquID Guide Catheter Extension is substantially equivalent to the Vascular Solutions/Teleflex Guideliner V3 Catheters (K172090). In addition, the Boston Scientific Guidezilla II Guide Extension Catheter (K163314), Medtronic Telescope Guide Extension Catheter (K183353) and the OX Medical Boosting Catheter (K160561) are included as reference devices.

Guide catheter extensions are designed to facilitate the placement of interventional devices. They are placed within the interior lumen and advanced beyond the distal tip of conventional guide catheters. These devices allow physicians to achieve deeper vascular intubation providing enhanced placement and support for subsequent interventional device delivery.

The LiquID device and, the predicate device, and the reference devices include a PTFE lined single lumen distal shaft that is metal (coil or braid) supported with an exterior polymer encapsulation layer. The device distal shafts have an exterior coating for lubricity and include radiopaque features. The devices transition from the distal shaft to a push rod with designs that allow the introduction of interventional devices from the guide catheter and into the device distal shaft. The device transitions are also designed for strength. The devices are EO sterilized and are conventionally packaged (hoop, pouch, and box).
