1. A delivery system comprising:

  • a delivery catheter having an catheter lumen extending from a proximal end of the delivery catheter to a distal end of the delivery catheter;

    an inner member extending through the catheter lumen, the inner member comprising a distal tip portion, a proximal portion, an intermediate portion and an inner lumen extending longitudinally therethrough from a proximal end of the inner member to a distal end of the inner member, wherein the intermediate portion is disposed adjacent to the distal end of the delivery catheter;

    a first sealing member positioned between the inner member and the delivery catheter, wherein the first sealing member forms a fluid seal between the inner member and an inside surface of the delivery catheter;

    a second sealing member positioned distally from the first sealing member between the inner member and the delivery catheter, wherein the second sealing member forms a fluid seal between the inner member and an inside surface of the delivery catheter;

    wherein the intermediate portion is at least that portion extending between the first sealing member and the second sealing member;

    a device-containing region between the intermediate portion and the delivery catheter, wherein the device-containing region is defined by the first sealing member and the second sealing membera delivery lumen extending longitudinally through the inner member from near a proximal end of the inner member and being in fluid communication with the device-containing region;

    a side port in the delivery catheter providing fluid communication between the device-containing region and an outside of the delivery catheter when the side port is positioned proximally of the second sealing member and distally of the first sealing member; and

    wherein the delivery catheter is movable relative to the inner member to position the side port distally of the second sealing member thereby the side port does not provide fluid communication between the device-containing region and the outside of the delivery catheter, the device-containing region thereby being entirely sealed from the outside of the delivery catheter.
