1. A probe assembly comprising:
a probe housing;
a probe that extends within the probe housing, the probe having a core segment, a coil segment forming coils around at least a portion of the core segment and forming a selectively permeable distal end, and a displacement segment; and
a probe actuator that is configured to advance the probe from a proximal position to a distal position, the probe actuator also being configured to manipulate the selectively permeable distal end,
wherein the probe actuator moves the displacement segment relative to the core segment to manipulate the selectively permeable distal end.
