Split-tip catheter

A catheter comprising:

• an elongate shaft having a proximal end portion and a distal end portion, the proximal and distal end portions defining a longitudinal axis, the elongate shaft defining a first shaft lumen and a second shaft lumen;
• and
• first and second tip segments, the first shaft lumen of the elongate shaft together with the first tip segment defining a first catheter lumen, and the second shaft lumen of the elongate shaft together with the second tip segment defining a second catheter lumen separate from the first catheter lumen, each tip segment having a proximal portion, a distal portion, and a distal end, the proximal portion of each tip segment fixed relative to the distal end portion of the elongate shaft and the distal ends being movable relative to each other, each tip segment defining a side opening located at an inner side of the respective tip segment and in fluid communication with a respective one of the first and second catheter lumens,
• wherein the tip segments are biased towards a curved configuration, in which each tip segment has a concave portion with respect to the longitudinal axis and the side openings face each other along the concave portions, and wherein each tip segment moves to a straight configuration, in which the respective tip segment is substantially parallel to the longitudinal axis, in response to an application of an external force to the respective tip segment, and moves from the straight configuration to the curved configuration in response to removal of the external force.
