  • a distal end, a proximal end and a proximal tip having a tip lumen;

    a rotatable innermost cannula having comprising a lumen, a proximal end, a proximal end portion, and a distal end, the rotatable innermost cannula extending from at least just proximal the distal end of the introducer and at least partially through the proximal tip lumen;

    the proximal tip disposed at the proximal end of the innermost cannula and comprising a distal end; and

    a retaining member comprising an engaging member extending radially outward, the retaining member disposed directly over and about the proximal end portion of the innermost cannula, whereby, in response to rotation of the innermost cannula with respect to the retaining member, the proximal tip is longitudinally movable relative to the engaging member between a retaining configuration and a releasing configuration, wherein the proximal tip and the engaging member are spaced from one another by a greater longitudinal distance in the releasing configuration than in the retaining configuration.
