Abstract
A safety device for shielding a sharp tip of a tubular needle includes a shaft sized and shaped for being received into the passage of the tubular needle through a first end of the passage and extending to a second end of the passage. A shield is associated with the shaft and is constructed for receiving and substantially shielding the sharp tip of the needle. A catch is associated with the shaft. The catch prevents the withdrawal of the shaft from the passage of the needle when the shield is shielding the sharp tip of the needle.
