1.1.1. Description

1.1.1. Description The ALLUNGA PTA Balloon Catheter is a high performance balloon catheter for peripheral indication. The device features an ultra-low profile, semi-compliant balloon combined with a low profile tip. The ALLUNGA PTA Balloon Catheter has a coaxial shaft design. The outer lumen is used for inflation of the balloon, and the wire lumen permits the use of guidewires to facilitate advancement of the catheter to and through the stenosis to be dilated. The balloon is designed to provide an inflatable segment of known diameter and length at recommended pressures. The catheter includes a tapered tip to facilitate advancement of the catheter to and through the stenosis. The working lengths of the balloon catheter (usable catheter length) vary and are selected based on patient requirements for PTA. The radiopaque marker(s) are placed beneath the working area (usable balloon length) of the balloon and are visible when used in conjunction with fluoroscopy and aid in the placement of the balloon. The effective length could increase by 1 cm in a fully hydrated state. Please check the package label for all individual product sizes. Each balloon inflates to the stated diameter and length at a specific pressure. The maximum rated burst pressure is different for each size - please check the package label for the rated burst pressure. It is important that the balloon not be inflated beyond the rated burst pressure. The proximal portion of the catheter includes one female luer-lock port connected to the inflation lumen, and one female luer-lock port for the guidewire lumen. The devices can be supplied with and without Hydrophilic coating so be sure to review your device selection by observing the box and package label. The Hydrophilic coating when applied is applied proximally of the balloon for a length of 40 cm. The PTA Balloon Catheter is a non-pyrogenic device. The ALLUNGA PTA Balloon-Catheter is for the purpose of the medical device law a temporary applicable surgical invasive product especially intended for diagnosis, control or correction of a heart disease (vessel occlusion) or central circulation system being exposed to these areas of the human body (class IIa, rule 7 acc. to Annex IX of directive 93/42ECC). Description: 140314aek ALLUNGA PTA Balloon Catheter_Description Page: 1-15

Indication The ALLUNGA PTA Balloon Catheter is indicated for Percutaneous Transluminal Angioplasty (PTA) in the peripheral vasculature, including iliac, femoral, ilio-femoral, popliteal, infra-popliteal and renal arteries, and for the treatment of obstructive lesions of native or synthetic arteriovenous dialysis fistulae. Contraindication The ALLUNGA PTA Balloon Catheter is contraindicated for use in coronary arteries or the neurovasculature, or when unable to cross the target lesion with a guidewire.

1.1.7. Conclusion

1.1.7. Conclusion Lowest entry profile in the industry with the addition of a beveled tip to allow for access to the most difficult lesions Maximum flexibility for easy navigation to reach the most distal lesions Increased pushability for a significant amount of applied force transition from the hub to the tip Fast inflation and deflation times to maximize efficiency during treatment and reducing the procedure time compared to other industry participants Reduced radiation exposure for clinician, team, and patient due to decreased time for balloon operation High rate burst pressure to optimize working range and to increase the safety level for the patients Description: 140314aek ALLUNGA PTA Balloon Catheter_Description Page: 15-15
