摘要： A retrieval catheter having a retrieval catheter tip 1 at a distal end thereof, the tip being suitable for retrieving an embolic protection filter into the tip 1. The tip 1 comprises a flexible tip body 2 and two stiff reinforcement columns 3. The tip body 2 is radially expandable to facilitate retrieval of a filter into the tip 1, and the columns 3 extend longitudinally along the tip body 2 to prevent buckling of the tip 1 upon retrieval of the filter into the tip. The cross-sectional area of the columns 3, the cross sectional area of the tip body 2, and the overall cross-sectional area of the tip 1 all remain substantially unchanged along the length of the tip 1. This ensures the reinforcement provided to the tip 1 by the columns 3 remains substantially uniform along the length of the tip 1. Thus no longitudinal squeezing of the filter as it is retrieved into the tip 1 will be caused.
摘要翻译：一种取出导管，其在其远端具有取回导管尖端1，所述尖端适于将栓塞保护过滤器收回到尖端1中。尖端1包括柔性末端主体2和两个刚性加强柱3。尖端体2是可径向扩张的，以便于将过滤器取出到尖端1中，并且柱3沿着尖端体2纵向延伸，以防止在将过滤器收回到尖端中时尖端1的弯曲。柱3的横截面面积，末端体2的横截面面积和尖端1的总横截面面积全部沿尖端1的长度基本保持不变。这确保了通过柱3提供给尖端1的加强沿着尖端1的长度保持基本均匀。因此，当过滤器被回收到尖端1中时，不会纵向挤压过滤器。

摘要： A catheter 1 suitable for advancement through a body passageway of a patient. The catheter 1 comprises a catheter body 4 which is flexible to provide the necessary trackability for the catheter 1 to advance through a body passageway, and two stainless steel reinforcement wires 5 extending along the catheter body 4 which provide the necessary pushability to advance the catheter 1 through the passageway. The reinforcements 5 are positioned diametrically opposed to one another by approximately 180 degrees on opposite sides of the longitudinal axis of the catheter 1, and the catheter body 4 is relatively soft and twistable. This configuration enables the entire catheter 1 to spontaneously twist during advancement so that the reinforcements 5 orientate themselves along a plane of neutral bending during advancement of the catheter 1. In this way, any resistance to the trackability of the catheter 1 due to the stiff reinforcements 5 is minimized.

摘要： A retrieval catheter 1 for retrieval of an embolic protection filter from a vasculature. The catheter 1 comprises a proximal hypotube 3, a radially offset distal shaft 4 and a centering shank 9. A guidewire lumen 13 is provided through the shank 9 in communication with a larger guidewire lumen 7 through the shaft 4 for a continuous guidewire passageway to accommodate passage of a guidewire 21 through the shank 9, the shaft 4 and out through a proximal guidewire opening 6 to facilitate rapid exchange of the catheter 1 over a guidewire 21. The shank 9 is movable between an introduction configuration in which the shank 9 protrudes distally from the shaft 4 to centre the catheter 1 during advancement through a vasculature, and a retrieval configuration in which the shank 9 is located within the guidewire lumen 7 to facilitate retrieval of an embolic protection filter into the shaft 4.
