Publication number: 20180206829Abstract: Methods and devices for providing a biopsy device with a modified handle and stylet that provides a vacuum to be delivered to the targeted tissue for removal. The vacuum may draw the tissue into the notch where the tissue may then be severed via the cannula. Alternatively, the tissue may be drawn into to the notch after being severed via the stylet and/or cannula. The vacuum may be used to bring a larger amount of tissue into the notch than would otherwise be brought in the notch if no vacuum was used, providing a larger sample through the same size access point.Type: ApplicationFiled: January 31, 2018Publication date: July 26, 2018Inventors: Michael Plishka, Evan Linderman, John A.

Publication number: 20160235435Abstract: A device and method is provided to gain access to interior body regions. The system includes a safety needle assembly, a blade assembly, an obturator assembly, and a dilator assembly. The safety needle assembly accesses an interior body region, after which the blade assembly expands the pathway created by the safety needle assembly. The obturator then further expands the pathway and delivers the dilator assembly to the desired location. The safety needle assembly, obturator assembly, and blade assembly are removed, leaving the dilator assembly in place for future procedures.Type: ApplicationFiled: February 18, 2015Publication date: August 18, 2016Inventors: Jon Kiev, Michael Plishka
