  • Patent number: 11540511
    Abstract: A protector assembly for handling, storing and transporting donor tissue in a transfer pipette includes a distal cap and a proximal plug that are respectively engageable with opposite ends of the pipette. Structurally, the pipette includes a distally tapered fluid chamber which is in fluid communication with an extension tube. The distal cap is dimensioned for friction engagement with the fluid chamber of the pipette and it is formed with a plurality of vents to establish fluid communication through the vents with the fluid chamber. On the other hand, the proximal plug is dimensioned for a friction engagement with the extension tube to prevent leakage of solution from the fluid chamber of the pipette when the proximal plug is engaged with the pipette. In combination, an engagement of the protector assembly with a pipette holding a donor tissue will protect and preserve the donor tissue during handling and transport.
