Multi-compartment Biopsy Syringe

Technology No. 20180232

Independent compartments; hand pump for expelling

Collect multiple samples in independent chambers using a novel multi-compartment syringe designed for fine needle aspiration (FNA) for lymph node and nodule/mass biopsies. The design features independent compartments within the syringe and a hand pump mechanism to expel contents of each chamber independently. This device eliminates the need for multiple syringes during a single procedure. It is envisioned to be an add-on to commercially available FNA needles.

More efficient and ergonomic

At present, EBUS and EUS procedures require three separate syringes, which is both time consuming and inefficient. This new device fits current FNA needles used for these procedures and offers a more efficient and ergonomic means of collecting and expelling needle contents.
