摘要： Embodiments disclosed herein are directed to an insertion tool (100) for a catheter. The insertion tool (100) engages a proximal end of an introducer (10) and includes a guide channel (106) that aligns with a lumen of the introducer (10). The guide channel (106) supports the catheter (50) to maintain columnar integrity as the catheter (50) is urged distally, past a valve and into the lumen of the introducer (10). In an embodiment, the attachment structure can be inserted past the valve to define a pathway for the catheter. Embodiments also include an elongate opening to allow lateral ingress/egress of the catheter, a segmented cylindrical shape to provide a shortened elongate opening, and an offset elongate opening to allow a rolling introduction of the catheter to the guide channel to prevent abrasion of any coatings disposed on the catheter.

摘要： A cannulator (100) can include a compound needle (104) and a compound cannula (102). The compound needle can include a needle (110), a dilator (108), and a needle hub (106). The dilator can be disposed over the needle with at least a tip of the needle extending beyond a distal end of the dilator. The needle hub can be around a proximal-end portion of the dilator. The compound cannula can include a cannula (140) and a cannula hub (142) around a proximal- end portion of the cannula. The cannulator can have a mated state of the compound needle and the compound cannula for at least cannulation with the cannulator. The mated state of the cannulator can include the dilator disposed in the cannula with a proximal-end portion of the cannula hub coupled to a distal-end portion of the needle hub.
