MRI GUIDED BIOPSY TARGETING SET WITH FIRING OBTURATOR

摘要

An MRI guided breast biopsy targeting set includes a firing obturator for use with positioning a breast biopsy device within a patient. The obturator is insertable into a targeting cannula in lieu of a needle of a biopsy device. The targeting set includes an obturator and a firing assembly. The firing assembly includes a housing, a latch mechanism, and a release mechanism. The firing assembly is responsive to the release mechanism to fire the obturator into the desired position within the breast.
