摘要： A guide wire locking mechanism for a catheter system includes a motion-limiting component adapted to contact a portion of a guide wire and limit the direction of motion that the guide wire can slide therethrough. The motion-limiting component allows the guide wire to slide in one direction when placed in the locking mechanism but prevents the guide wire from moving in the opposite direction. The motion-limiting component can be made from a row of movable teeth having contact surfaces or faces which come in contact with a portion of the guide wire. The teeth are bendable to allow the guide wire to move in one direction but will tighten against the guide wire if one attempts to move the guide wire in an opposite direction. The guide wire locking mechanism can be used with a recovery sheath that can be advanced over the guide wire to collapse an expandable filtering portion mounted on a guide wire. The locking mechanism helps to maintain the recovery catheter on the collapsed filtering portion to allow both the recovery catheter and the filtering device to be simultaneously removed from the patient's vasculature, thus preventing the possibility that the recovery catheter can somehow be retracted off the filtering portion during removal.
摘要翻译：用于导管系统的引导线锁定机构包括适于接触导丝的一部分并限制导丝可以滑动通过其的运动方向的运动限制部件。运动限制部件允许导线在放置在锁定机构中时沿一个方向滑动，但是防止导丝沿相反方向移动。运动限制部件可以由具有与导丝的一部分接触的接触面或面的一排可动齿制成。齿是可弯曲的，以允许导丝沿一个方向移动，但是如果试图沿相反方向移动导丝，则它将紧靠导丝。引导线锁定机构可以与可以在引导线上前进的恢复护套一起使用，以使安装在导丝上的可扩展过滤部分折叠。锁定机构有助于将收缩的导管保持在塌陷的过滤部分上，以允许恢复导管和过滤装置同时从患者的脉管系统中移除，从而防止恢复导管以某种方式从过滤部分中退出的可能性删除。

摘要： Embodiments include an infusion-occlusion system having a delivery catheter, a guide catheter adapted to receive the delivery catheter, and a guidewire with an occlusion device adapted to be received within the guide catheter. The guide catheter of the catheter kit may be provided with an occlusion device at the distal end of the guide catheter. The delivery catheter may have an accessory lumen, coaxial or co-linear lumen, a supporting mandrel, or an occlusion device at its distal end. Moreover, according to some embodiments, occlusion devices may be a single material or a composite balloon having an inner liner and an outer layer of different materials, a high compliance low pressure balloon, or a filter device that restricts particles from passing through but does not restrict fluid, such as blood. An inflation device with a large volume and low volume syringe can be used to inflate the balloon.
