    摘要： Devices, systems and methods wherein a dilator, such as a balloon or other expandable member, is positionable within the frontal sinus ostium and adjacent frontal recess and useable to dilate the frontal sinus ostium and substantially all of the frontal sinus recess without requiring repositioning and repeated re-expansion of the dilator. One balloon catheter device of the invention comprises a catheter body that is less than about 50 cm in length (and in some embodiments less than 25 cm in length and a semi-compliant or non-compliant balloon on the catheter body. The balloon may have a working length of about 12 mm to about 30 mm and a width at its widest point when fully inflated of about 2 mm to about 7 mm. Such balloon may be constructed to withstand inflation pressures of about 12 atmospheres. In some embodiments, the dilator is advanced through or over a guide (e.g., guidewire or guide catheter) that has a preformed shape.

    摘要： Balloon catheter, guide catheter and method for dilating openings in paranasal sinuses. A non-removable guide member (e.g., guidewire) extends from the distal end of the balloon catheter. The non-removable guide member initially passes through the opening of the paranasal sinus and is followed by the catheter body on which the balloon is mounted. The balloon is then inflated causing dilation of the opening of the paranasal sinus. In some embodiments, the non-removable guide member may be shapeable so that the operator may place the non-removable guide member in a desired shape prior to insertion of the balloon catheter. In some embodiments, the length of the non-removable guide member may be adjustable such that the operator may adjust the length of the non-removable guide member prior to insertion of the balloon catheter.
