  • Biopsy needle design
    Patent number: 10478159
    Abstract: A biopsy needle assembly includes a mandrel within a cannula, the needle assembly is fired into a target tissue to obtain a tissue sample using a force source imparting movement to the needle assembly. The mandrel and cannula design, and force source characteristics minimize needle deflection, and allow the needle assembly to excise extended length tissue samples. The mandrel forms tissue retention ridges within a tissue sample region to reduce fragmentation of the tissue sample.
    Type: Grant
    Filed: January 9, 2019
    Date of Patent: November 19, 2019
    Assignee: 3DBiopsy, Inc.
    Inventors: Nelson N. Stone, David Abraham Schechter, Joshua Kalo Goetz, Timothy Patrick Crowley
