摘要：
In some examples, a catheter includes an elongated body extending between a proximal end and a distal end, and defining an inner lumen, an outer body wall having a wall cross-sectional diameter, and a distal aperture at the distal end. A distal portion of the elongated body including a taper section that tapers from the outer body wall of the distal portion to the distal aperture, with the distal portion defining a plurality of slits open to the distal aperture. The distal aperture has an aperture diameter greater than zero and less than the wall cross-sectional diameter. The distal portion defining the plurality of slits is configured to substantially center the distal end around a guide member when the guide member is introduced in the inner lumen and extends through the distal aperture.
