Abstract
The purpose of this article is to discuss the development of a dedicated halfpipe coaxial cannula for stereotactic vacuum-assisted biopsy. We evaluated the system by retrieving 18 copper targets from a pig breast model in the upright position via vertical and lateral approaches. Sampling was successful in 15 of 18 cases. Errors occurred only in superficial lesions biopsied via the vertical approach. The halfpipe coaxial cannula shows promise for improving positioning accuracy, avoiding target dislocation, and obviating repeated needle repositioning.
