Abstract
A pre-curved catheter includes a hub and an elastically deformable tubular body coupled to the hub. The elastically deformable tubular body can include a first body segment including a first body segment length including a lumen, a second body segment distal the first body segment, the second body segment including a second body segment length, and a first transitional body segment interposed between the first body segment and the second body segment. The first transitional body segment can include a selected first degree of curvature representing an angular change between a direction in an orientation of the first body segment and a direction in an orientation of the second body segment.
Claims23
A pre-curved catheter comprising:
- a hub;
- and
- an elastically deformable tubular body coupled to the hub, the elastically deformable tubular body comprising:
- a first body segment including a first body segment length including a lumen;
- a second body segment distal the first body segment, the second body segment including a second body segment length;
- and
- a first transitional body segment being interposed between the first body segment and the second body segment and having a selected first degree of curvature representing an angular change between a direction in an orientation of the first body segment and a direction in an orientation of the second body segment.
A catheter insertion kit comprising:
- a pre-curved catheter including:
- a hub;
- and
- the elastically deformable tubular body coupled to the hub, the elastically deformable tubular body comprising:
- a first body segment including a first body segment length including a lumen;
- a second body segment distal the first body segment, the second body segment including a second body segment length;
- and
- a first transitional body segment having a first transitional body segment length being interposed between the first body segment and the second body segment providing a selected first degree of curvature with an angular change between a direction in an orientation of the first body segment and a direction in an orientation of the second body segment as measured from a first reference point being a distal end of the first body segment;
- and
- an introducer needle including a rigid body having a proximal end, a distal end ending in a point, and a diameter in a range of 14-26 gauge, wherein a lumen of the elastically deformable tubular body of the pre-curved catheter is sized to receive the introducer needle for insertion and advancement through the lumen so that at least a portion of the rigid body extends past a distal end of the second body segment.
