Intended Use

The GuardDOG™ Occlusion System is indicated for use in the peripheral vasculature to facilitate the localized infusion of therapeutic or diagnostic fluids, with or without vessel occlusion. The safety and effectiveness of this device have not been established in the coronary, cerebral, or carotid vasculature.

Device Story

GuardDOG Occlusion System is a temporary occlusion catheter used in peripheral vasculature. System comprises a 0.014" diameter occlusion guide wire (200 or 300 cm) with a distal compliant elastomer balloon and a CO2 inflation device. Physician operates device to navigate to target vessel; inflates balloon using CO2 to occlude blood flow; facilitates localized infusion of therapeutic or diagnostic fluids. CO2 inflation medium (max 5 cc) provides safety benefit over air embolism risk. Device compatible with standard interventional tools (introducers, guide catheters). Benefits include controlled vascular access and localized fluid delivery. Used in clinical settings by physicians.

Clinical Evidence

Bench testing and animal studies only. Canine vessel safety study compared GuardDOG to Equinox, showing no significant vessel injury and effective occlusion. Additional animal studies confirmed device integrity, trackability, and compatibility with standard interventional devices.

Technological Characteristics

Single lumen 0.014" OD guide wire with distal compliant elastomer balloon. Inflation medium: CO2. Biocompatible per ISO 10993-1. Sterile, single-use. Compatible with standard interventional devices.

Indications for Use

Indicated for use in peripheral vasculature to facilitate localized infusion of therapeutic or diagnostic fluids, with or without vessel occlusion. Not indicated for coronary, cerebral, or carotid vasculature.

Regulatory Classification

Identification

A vascular clamp is a surgical instrument used to occlude a blood vessel temporarily.

#### DEVICE DESCRIPTION

The GuardDOG System consists of two components: a carbon dioxide (CO2) Inflation Device and a balloon Occlusion Guide Wire. The GuardDOG Inflation Device is a disposable syringe assembly, which is prepackaged with carbon dioxide and is used to inflate the Occlusion Guide Wire. The GuardDOG Occlusion Guide Wire is a 200 or 300cm long by 0.014" outside diameter Catheter with an inflatable balloon on the distal end. The guide wire is inflated via a detachable hub, which is connected to the Inflation Device.

The GuardDOG Occlusion System is equivalent to the predicate devices in technical characteristics.

Functional and mechanical integrity testing has been performed. The results verify equivalency to the predicate devices and appropriate safety and efficacy of the GuardDOG Occlusion System for the intended use.

One difference is that the GuardDOG Occlusion System uses CO2 gas as the inflation medium; both predicate devices use a 1:1 mixture of 60% contrast in saline. However, CO2 is an accepted contrast agent for use in the peripheral vasculature. A literature search was done to evaluate the effects of CO2 in the circulatory system. The results demonstrate that CO2 doses of 5-250cc are safe in the peripheral vasculature. The design of the GuardDOG System limits the potential exposure to CO2 to 5 cc or less. In addition, the GuardDOG is packaged such that CO2 is maintained at high purity (greater than 95%) and thus potential balloon failure will expose the patient to CO2 rather than to air embolism. Finally, the rated burst diameter of the GuardDOG Occlusion Guide Wire balloon is 9.26 mm and provides an acceptable margin of error over the recommended 3-6 mm vessel occlusion range. These results, individually and taken together, demonstrate equivalency to the predicate devices and appropriate safety and efficacy of the GuardDOG Occlusion System for the intended use.

### NON-CLINICAL TESTS

Biocompatibility of the GuardDOG system was evaluated in compliance with Good Laboratory Practice (GLP) for Nonclinical Laboratory Studies, 21 CFR Part 58 and according to the recommendations in ISO 10993-1 Biological Evaluation of Medical Devices - Part One. The results, reported in the Biocompatibility tab, demonstrate that the GuardDOG materials and manufacturing methods are appropriate and safe for the intended use. In addition, the GuardDOG System is sterilized according to industry standard procedures and is packaged appropriately in packaging that maintains a sterile barrier and device integrity as reported in the Packaging and Sterilization tab.

A Vesscl Safety Animal Study was performed to compared the incidence of acute vessel injury between the GuardDOG Occlusion System and the Equinox Occlusion Balloon Catheter in a canine model. The study concluded that the GuardDOG performed well with regard to vessel occlusion and does not cause any significant vessel injury compared

{3}------------------------------------------------

to the predicate device. These results demonstrate appropriate safety of the GuardDOG Occlusion System for the intended use and equivalence to the predicate device.

Additional animal studies were conducted to evaluate device integrity, track to a targeted vascular site and deliver an infusion catheter device the intended vascular territory. The GuardDOG Occlusion System is compatible with standard interventional devices such as introducers, guide catheters, and infusion catheters and is equivalent to the predicate devices based on acceptable results in these tests.

#### CONCLUSION

The data presented in this Premarket Notification establish that the GuardDOG Occlusion System is equivalent to the predicate devices and demonstrate appropriate safety and efficacy of the GuardDOG Occlusion System for use in the peripheral vasculature to facilitate the localized infusion of therapeutic or diagnostic fluids, with or without vessel occlusion.
