1. A brush for non-invasive biopsy, comprising:
a distal tip forming a cavity,
wherein an opening of the cavity faces proximally;
a shaft that is movable relative to the distal tip,
wherein a distal end of the shaft is located within the cavity when the brush is in a first state,
and wherein at least a portion of the distal end of the shaft is located outside the cavity when the brush is in a second state;
an outer sheath,
wherein the shaft extends through the outer sheath;
a set of bristles located at the distal end of the shaft,
wherein the bristles are configured to at least partially move from within the cavity of the distal tip to outside the cavity of the distal tip when the brush moves from the first state to the second state,
and wherein the bristles are moveable proximally relative to the distal tip while the distal tip remains fixed relative to the outer sheath when the brush is in the second state;
and a plug located at a distal end of the outer sheath,
wherein the plug at least partially seals a distal-end opening of the outer sheath,
and wherein the shaft extends through an opening of the plug,
wherein at least a portion of the plug is configured to retract into the outer sheath when the brush moves from the first state to the second state.
