Safety Mechanism

A method of engaging a safety mechanism with a tip of an elongate medical device, comprising:

• withdrawing the elongate medical device proximally along a longitudinal axis, through a first keyhole aperture disposed in a first tab of a clip;
• transitioning the clip from a first configuration to a second configuration, the clip fixedly engaging the elongate medical device in the second configuration to prevent any longitudinal movement therebetween, the clip coupled to a sheath;
• and
• disengaging a first grip from a needle hub to disengage the sheath from the needle hub, the first grip coupled to the first tab.

A method of manufacturing a safety assembly, comprising:

• forming a clip from a first material, the clip comprising:
• a first arm, including a first tab, a first plate, and a first grip, the first tab including a first keyhole aperture;
• a second arm, including a second tab, a second plate, and a second grip, the second tab including a second keyhole aperture;
• and
• a biasing member extending from the first arm to the second arm;
• folding the first tab and the first grip through an angle of 90 degrees relative to the first plate;
• folding the second tab and the second grip through an angle of 90 degrees relative to the second plate;
• forming a sheath from a second material, the sheath including a body defining a lumen and a shroud including a sheath aperture extending therethrough;
• and
• coupling the clip to the sheath wherein one of the first grip or the second grip extends through the sheath aperture.

A safety mechanism, comprising:

• an elongate medical device having a shaft extending along a longitudinal axis and defining a first outer diameter, the shaft including a notch extending annularly and defining a second outer diameter, less than the first outer diameter;
• a sheath including a body defining a lumen configured to receive the elongate medical device therethrough, and a shroud extending axially and including a sheath aperture;
• and
• a clip configured to transition between a first configuration and second configuration, the clip comprising:
• an arm, including a tab, a plate, and a grip, the tab including a keyhole aperture;
• and
• a biasing member coupled to the plate and extending annularly about an outer surface of the sheath, and configured to bias the tab towards the second configuration, the elongate medical device extending through first keyhole aperture, the grip extending through the sheath aperture.
