Abstract
A hemodialysis split-tip catheter comprises an elongated portion, a proximal end and a distal end defining a longitudinal axis. The proximal end attaches to a hub with suture wings assembly, which in turn connected to extension tubings. The distal end has two distal tip segments splitted from each other. The first distal tip segment has a concave shape with respect to the longitudinal axis and the second distal tip segment has an approximately J-shape with respect to first distal tip segment. Diameter of concave shape of first distal tip segment is larger than diameter of J-shape of second distal tip segment to facilitate backward bend of second distal tip segment with respect to first distal tip segment after a catheter insertion inside a blood vessel to face a blood flow direction.
Claims10
A hemodialysis split-tip catheter comprising:
- an elongated portion, a proximal end and a distal end defining a longitudinal axis;
- an elongated portion comprising a catheter body;
- a proximal end comprising:
- a hub with suture wing assembly, and extension tubings fluidly connect catheter lumens to a blood treatment unit;
- and
- a distal end comprising two splitted distal tip segments comprising:
- a first distal tip segment has a concave shape with respect to the longitudinal axis, a straight tip, a side hole and a distal tip opening;
- and
- a second distal tip segment has an approximately J-shape with respect to the first distal tip segment and a distal tip opening.
A hemodialysis split-tip catheter having two split distal tip segments being designed and arranged to minimize blood recirculation wherein a distance between the distal tip opening of the first distal tip segment and the distal tip opening of the second distal tip segment is more than 30 mm.
