  • Patent number: 11226270
    Abstract: Device for collecting lymph nodes from fatty tissue, which includes a fenestrated sample chamber configured to receive a sample of fatty tissue having lymph nodes; a lockable gate that regulates passage of tissue out of the sample chamber longitudinally; and a pusher that moves longitudinally through the chamber. After treating a sample of resected fatty tissue with a solvent that dissolves fat, the sample is pushed through the fenestrated sample chamber, where the dissolved fat is eluted transversely through the fenestrations. Remaining lymph nodes, arteries, veins, nerves and connective tissue are packed to form a tissue block, which is sized for use with histology cassettes.

  • Patent number: 10539485
    Abstract: Devices and methods for yielding lymph nodes from fatty tissue, the device including a fenestrated sample chamber configured to receive a sample of fatty tissue having lymph nodes; a lockable gate switchable between a closed position that is locked and an open position; a pusher configured to push the sample against the gate when locked in the closed position to compress the tissue, and configured to push the compressed tissue out of the sample chamber when the gate is subsequently opened; and a cutting chamber aligned distal to the sample chamber for receiving compressed tissue from the sample chamber, the cutting chamber comprising sets of opposing through slots aligned to permit slicing of the compressed tissue into sections, thereby yielding lymph nodes from the fatty tissue.
