Multicenter evaluation of a new ultrasound-guided biopsy device: Improved ergonomics, sampling and rebiopsy rates.

The purpose of this study was to evaluate performance, ergonomics, and immediate rebiopsy rate of a new vacuum-assisted biopsy (VAB) device for ultrasound-guided breast biopsies. Between December 2002 and April 2003, 113 patients meeting study criteria were biopsied at four centers using the new 9 gauge VAB device. The device has a radiofrequency-tipped probe, 360 degrees vacuum, a circumferential cutter, and a coaxial cannula for multiple sampling.
