1. A biological conveyance system comprising:
a catheter having a lumen extending therethrough;
an elongated screw having a proximal end and a distal end, the elongated screw positioned within the lumen of the catheter;
the elongated screw having a helical shape formed from a plurality of loops and a throughway extending between the distal end of the elongated screw and the proximal end of the elongated screw; the throughway being formed entirely from and within an interior diameter of each of the plurality of loops and forming a passage that is continuous between the proximal end and the distal end of the elongated screw; the throughway of the elongated helical member allowing passage of a guidewire through the elongated screw;
a rotational mechanism linked to the elongated screw and configured to rotate the elongated screw so as to proximally retract biological material fixed within a patient; and,
an introducer sleeve positioned within the lumen of the catheter and having a proximal opening, a distal opening, and with at least one side opening exposing an interior of the introducer sleeve with an exterior of the introducer sleeve.
