Description

The Paclitaxel-eluting balloon “Luminor 18” is a coaxialcatheter (OTW, over-the-wire) designed for percutaneous transluminal angioplasties of small peripheral arteries.

The guidewire runs into the inner lumen while the outer lumen is intended for contrast medium flow. The maximum diameter of the guide wire must not exceed 0.46 mm = 0.018 inches. Optionally, a guidewire measuring 0.014” = 0.36 mm can be used under medical criteria and in the cases where it is required by the lesion to be treated.

On the catheter’s distal part, just before the tip, there is the balloon (inflatable segment) that will dilate the artery upon inflating by means of infusion of contrast fluid inside it. The connector is Y-shaped and it has two entry ports:

– The straight port is intended for guidewire passage.

– The side port allows contrast medium flow to dilate the balloon

The balloon is coated with a homogeneous mixture of Paclitaxel, a derivative of Taxol, and a  physiologically innocuous matrix, the excipient. The drug’s dose is 3 µg/mm² of balloon surface and it is intended to avoid cellular proliferation, consequently decreasing re-intervention rate.

The drug is released from the balloon by means of a rapid inflation so that a high dose is released in a very short period of time. In order to assure a sufficient dosage of Paclitaxel onto the arterial wall, inflation process must last from 30 seconds to 1 minute. Dilation of the lesion can be optimized by using longer inflation times at operator’s discretion.

The balloon is designed to reach different diameters at different pressures, as predicted by the compliance curve included on the primary packaging.

Two radiopaque markers are located at each end of the balloon in order to mark its length and help the user to see the catheter while navigating inside the patient.

Indications

Dilatation of stenosis in iliac, femoral, iliofemoral, popliteal, infra-popliteal and renal arteries, as well as for the treatment of obstructive lesions of arteriovenous fistulas, whether original or artificial, with a reference diameter balloon from 2 to 8 mm and lengths from 20 to 200 mm. It is also indicated for stent post-dilation in the peripheral vascular system.

Features
