Halfpipe coaxial cannula for self-contained vacuum-assisted biopsy systems: feasibility in a pig breast model.

Objective: 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.

Conclusion: Sampling was successful in 15 of 18 cases.
