Read the full statement (116 words)
The TeesuVac Breast Biopsy Device Mark 1 is indicated to obtain percutaneous core biopsy specimens from soft tissue,
and tumors of the breast. This product is intended for diagnostic use only, NOT therapeutic therapy. The instrument is
intended to provide breast tissue for histologic examination with partial or complete removal of the imaged abnormality.
The extent of histologic abnormality cannot be reliably determined from its mammographic appearance. Therefore, the extent
of removing the imaged evidence of an abnormality does not predict the extent of removal of a histologic abnormality (e.g.,
malignancy). When the sampled abnormality is not histologically benign, it is essential that the tissue
margins be examined for completeness of removal using standard surgical procedures.
Indications for use as stated in the FDA summary.
