<p>A device for inhibiting unintentional contact with the tip of a needle (122) that has a wire guide disposed in a lumen thereof. A housing (102) 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 (110) is located within the cavity, defining a distal opening, and a proxima 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 When the needle tip is within the cavity, and the needle is withdrawn from the distal opening of the pivoting member, a spring (126) or a compressible member cants the pivoting member into locking engagement with the needle to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.</p> |
