Publication number: 20070016101Abstract: A biopsy device used to capture a tissue sample by placing the tissue under tension, thus allowing a greater sized sample with increased quality. The device uses a rotating cannula and stylet with a concave “sample notch.” The rotation of the stylet places the tissue under tension while the rotation of the cannula as it is fired severs the sample.Type: ApplicationFiled: July 13, 2006Publication date: January 18, 2007Inventors: Dennis Feldman, Heather Hanson, Mark Heistand, Theodore Kramer
