    摘要： A medical device, and a system and packaged kit containing the medical device for the treatment of a sinus opening is described. The medical device comprises a proximal end, a distal end, and a shaft system having an inflation lumen and an irrigation lumen the proximal and. The shaft system has a proximal shaft section and a distal shaft section. An inflatable balloon is attached to the distal shaft section in a position that is proximal to said distal end. The irrigation tip is distal to the balloon on the distal shaft section and has a tip opening and one or more radially facing openings. A method for treating a sinus opening includes inserting a system that includes the medical device, a sinus guide catheter and a sinus guide element into a patient's anatomy, dilating the sinus opening and irrigating a target in the nasal anatomy.

    摘要： A method for the treatment of a stenosis or an occlusion in a blood vessel is disclosed in which a main catheter is first delivered to a site proximal to the occlusion. The main catheter may include an occlusive device at its distal end. An inner catheter or elongate member (e.g., a guidewire) having an occlusive device at its distal end is delivered to the site of the occlusion, and the occlusive device is activated at a site distal to the occlusion. A therapy catheter is then introduced to treat the occlusion. Next, a catheter is delivered just proximal to the occlusive device, and this catheter is used to aspirate and/or irrigate the area removing particles and debris. The aspiration and irrigation steps are preferably repeated until the particles and debris are removed. Perfusion may be performed by using a perfusion-filter distal of the lesion to be treated or a hypotube which extends beyond the occlusive device attached to the guidewire. The present invention provides for a minimally invasive procedure which can be performed quickly and efficiently, with reduced risks to the patient.

    摘要： Disclosed herein is a compliant catheter balloon with an improved elastic response and reduced longitudinal expansion, and a method of forming the same. The balloon comprises a SEBS block copolymer, which is longitudinally pre-stretched during the balloon manufacture process. In order to control the working length of a balloon on a catheter, at least one adhesive stop is provided on the catheter which prevents adhesive from wicking into the working length of the balloon. Preferably, a pair of thermoset tubings with an outer diameter size close to the size of the inner diameter of the balloon are inserted on the distal portion of the catheter. After the proper placement of the balloon, the adhesive is applied at the balloon's proximal and distal ends. As the adhesive wicks to the balloon, the thermoset tubings will eventually stop the adhesive to prevent further wicking of adhesive into the balloon's working length. In another aspect of the present invention, there is provided a method of manufacturing a balloon catheter to improve centering of the balloon on the catheter. After a balloon tubing is stretched, the stretched tubing is clamped to a fixture and stabilized at about 100° C. for 15 minutes. This stabilization step ensures that a balloon mounted on a catheter will inflate in a uniform manner.
