Intended Use

The Vanguard Dx™ catheter is intended for use in the delivery of radiopaque contrast media and common flushing agents to the vascular system.

Device Story

Vanguard Dx™ is a sterile, single-use diagnostic angiographic catheter (4F or 5F) used in cardiology and radiology. It delivers radiopaque contrast media and flushing agents to specific vascular sites for imaging. The device features a soft tip with an integrated restrictor and side holes; this design limits forward flow through the tip and promotes fluid dispersion through side holes, creating a 'cloud' of contrast. This mechanism reduces jetting, whip, and random tip oscillations, enhancing tip stability and reducing potential vascular trauma. The catheter is designed to mate with standard fluid delivery systems and is compatible with common contrast agents. It is operated by clinicians during diagnostic procedures to improve image quality and patient safety by minimizing mechanical trauma to the artery.

Clinical Evidence

Bench testing only. No clinical data provided. In-vitro verification included dimensional analysis, hub durability, leakage, stress cracking, joint strength, burst pressure, flow characterization, tip stability, guidewire/catheter insertion force, stiffness, torquability, and radiopacity. Biocompatibility testing followed ISO 10993-1 through 11, including cytotoxicity, irritation, systemic toxicity, pyrogenicity, sensitization, and hemocompatibility assays. Shelf life and packaging validation included accelerated aging and distribution simulation.

Technological Characteristics

Materials: Nylon (shaft, soft-tip, atraumatic-tip). Design: 4F and 5F diameters; selective and flush styles. Features: Integrated tip restrictor and side holes for flow dispersion. Connectivity: Female Luer hub. Sterilization: Sterile, single-use. Energy: Passive (manual/power injection). Standards: ISO 10993-1 through 11 (biocompatibility).

Indications for Use

Indicated for use in the delivery of radiopaque contrast media and common flushing agents to the vascular system in patients undergoing diagnostic angiography. Contraindicated for multi-patient use, use in MRI environments, drug infusion, or chemotherapy.

Regulatory Classification

Identification

An intravascular diagnostic catheter is a device used to record intracardiac pressures, to sample blood, and to introduce substances into the heart and vessels. Included in this generic device are right-heart catheters, left-heart catheters, and angiographic catheters, among others.

#### Warnings and Precautions IV.

A list of warnings and precautions can be found in the device labeling.

#### Device Description V.

The Vanguard Dx™ is a sterile, single patient use diagnostic catheter for use in cardiology and radiology during angiography. Vanguard Dx™ is the proprietary name for a family of 30 angiographic catheters. The Vanguard Dx™ is similar to other diagnostic catheters on the market in that it delivers radiopaque fluids and common flushing agents to a specific artery in the cardiovascular system for the purpose of differentiating the vessel from the surrounding anatomy during diagnostic imaging procedures. Vanguard Dx™ is available in 4 French and 5 French sizes. It is offered in both flush and selective styles.

The Vanguard Dx™ catheter was designed to enable the effective use of power injection using smaller diameter catheters while reducing the negative effects seen with many

{1}------------------------------------------------

similar catheters such as jetting, whip, and endovascular damage. The differentiating elements of the of Vanguard Dx™ lies in the combination of small holes near the stem/tip interface and a soft tip with an incorporated restrictor that combine to produce clinically beneficial effects. These effects include the creation of a "cloud" of contrast gently exiting through the side holes, which envelops the tip, rather than a single stream of contrast exiting the tip. This reduces the likelihood of vascular injury and has the potential to enhance image quality. Another effect is that a restrictor is incorporated into the tip that limits the flow through the catheter tip thereby encouraging flow through the catheter side holes. The reduction of forward flow through the tip and resulting dispersion of fluid through the side holes produces more balanced hydraulic forces on the catheter during injections so that random oscillations of the tip and rearward motion of the catheter are effectively reduced or eliminated. The result is a more uniform distribution of fluid around the catheter, reduced trauma to the catheterized artery, increased catheter tip stability during a procedure, and potential for enhanced image quality.

Vanguard DxTM catheters are designed to mate with commercially available fluid delivery products. The finished catheter is compatible with common contrast agents such as Omnipaque 350. Isovue 370. Optiray 350. Ultravist 370, Renografin 76, and Visipaque 320. Vanguard Dx™ is fully biocompatible including compatibility with human blood, saline, and heparinized saline.

### VI. Marketing History

The Vanguard Dx™ catheter has not been marketed in the United States or in any other country.
