The inner stylet wire has a pre-curved portion and is coupled to a proximal portion of the housing. The outer tubing is coupled to the button. Movement of the button within the channel is configured to selectively expose and cover at least a portion of the pre-curved distal portion of the inner stylet wire with the outer tubing.</p> |
