摘要：
A system comprising a tubular guide device (900, 1000) in combination with a balloon catheter (1400) sized and configured to advance it through the tubular guide device into an opening of a paranasal sinus to dilate the opening of a breast paranasal inflating the balloon catheter. wherein said tubular guide device comprises: a proximal tubular part (906) having a proximal end, a lumen, and a distal end； a tubular distal part (902) extending from the distal end of the proximal part and having a lumen that is substantially coaxial with the lumen of the proximal part and a distal end (904), and suitable for transnasal insertion and positioning of the guiding device such that the distal end of the distal part is located within or adjacent to the opening of the paranasal sinus, and said balloon catheter (1400) comprises a balloon (1404) and an elongated shaft (1402) characterized in that, having a proximal part comprising a visual marker (1416) to verify the relative location of the balloon with respect to the distal end of the guide device during the introduction of the balloon catheter through the guide device, in which the visual marker is placed on said axis such that it enters completely into the proximal end of the guiding device when the balloon emerges completely out of the distal end of the guiding device.Un sistema que comprende un dispositivo de guía tubular (900, 1000) en combinación con un catéter con globo (1400) dimensionado y configurado para hacerlo avanzar través del dispositivo de guía tubular en una abertura de un seno paranasal para dilatar la abertura de un seno paranasal inflando el catéter con globo. en el que dicho dispositivo de guía tubular comprende: una parte tubular proximal (906) que tiene un extremo proximal, un lumen, y un extremo distal； una parte distal tubular (902) que se extiende desde el extremo distal de la parte proximal y que tiene un lumen que es sustancialmente coaxial con el lumen de la parte proximal y un extremo distal (904)
