ABSTRACT:
A device for inhibiting unintentional contact with the tip of a needle that has a wire guide disposed in a lumen thereof. A housing of the device has an interior cavity. A portion of the needle extends through the cavity and a tip of the needle is located outside of the housing during use of the needle. A pivoting member is located within the cavity and defines a distal opening and a proximal opening which are sized to allow the needle to pass through the openings. When the needle tip is within the cavity and the needle is withdrawn from the distal opening of the pivoting member, a spring or a compressible member cants the pivoting member into locking engagement with the needle to prevent further movement of the needle. Alternatively, a spring is in locking engagement with the needle to prevent its further movement. When the pivoting member is canted about the needle, a slot of the pivoting member is generally aligned with the tip of the needle so that the wire guide can extend through the slot while further forward movement of the needle through the slot is prevented.
