Splittable Needle for Catheter Placement System

A method of flushing an implanted catheter, comprising:

• withdrawing a first plunger, slidably engaged with a first chamber of a body, to draw a predetermined volume of fluid through a nozzle and into the first chamber;
• transitioning a locking mechanism to an unlocked position, using the fluid within the first chamber, to disengage the locking mechanism from a second plunger;
• and
• sliding the second plunger distally to urge a flushing solution that is prefilled within a second chamber of the body through the nozzle and into the implanted catheter.

A catheter and flushing system, comprising:

• a catheter extending between a proximal end and a distal tip;
• and
• a flushing system, comprising:
• a body defining a first chamber and a second chamber;
• a first plunger slidably engaged with the first chamber;
• a second plunger slidably engaged with the second chamber, the second chamber prefilled with a flushing solution;
• and
• a locking mechanism configured, in the locked position, to prevent the second plunger from moving, and configured to transition to an unlocked position to allow the second plunger to move when a predetermined volume of fluid is disposed within the first chamber.
