MAGNETIC CATHETER SYSTEM AND METHODS

Abstract:

A catheter system may include a needle assembly coupled to a catheter adapter. The needle assembly may include a housing, an introducer needle, a distal opening, a first magnet, and a second magnet. In response to proximal withdrawal of the introducer needle, the first magnet may move towards the second magnet, which may block the distal opening and/or prevent blood from leaking out the distal opening.
