A swallowable cell sampling device comprising:
- an abrasive and sponge-like material capable of collecting cells from a surface of a human esophagus;
- a means for retrieval comprising a cord;
- an attachment loop formed by looping the cord around a central portion of the abrasive material;
- and
- a hitch knot adjustably securing the attachment loop such that during retrieval of the cell sampling device, tightening of the attachment loop compresses the central portion of the abrasive material while an outer diameter of the abrasive material remains substantially constant.
