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 (6) into the tip (1). The tip (1) comprises a flexible tip body and two stiff reinforcement columns. The tip body is radially expandable to facilitate retrieval of a filter into the tip (1), and the columns extend longitudinally along the tip body to prevent buckling of the tip (1) upon retrieval of the filter into the tip. The cross-sectional area of the columns, the cross sectional area of the tip body, 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 by the columns remains substantially uniform along the length of the tip (1). Thus no longitudinal squeezing of the filter (6) as it is retrieved into the tip (1) will be caused.

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 minimised.
