The en-bloc Biopsy System is indicated to provide tissue samples for diagnostic sampling of breast abnormalities.
The en-bloc Biopsy System is intended to provide breast tissue for histologic examination with partial or complete removal of an imaged abnormality.
The en-bloc Biopsy System is intended to provide breast tissue for histologic examination with partial removal of a palpable abnormality.
The extent of a histologic abnormality cannot always be readily determined from palpation or imaged appearance. Therefore, the extent of removal of the palpable or 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.
In instances when a patient presents with a palpable abnormality that has been classified as benign by clinical and/or radiological criteria (e.g., fibroadenoma, fibrocystic lesion), the en-bloc Biopsy System may also be used to partially remove such palpable lesions. Whenever breast tissue is removed, histologic evaluation of the tissue is the standard of care. 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.
The en-bloc is a percutaneous high frequency, automated, vacuum-assisted electrosurgical device used to remove tissue by automated electrosurgical cutting and simultaneous capture of an incised tissue volume. The Neothermia en-bloc ™ consists of a hand-held biopsy handle, upon which the single-use en-bloc Biopsy Probe is attached, with an integral cable to connect the handle to the control unit. The Probe™ contains two sets of active electrodes at its distal end - a precursor electrode and cutting/capture electrodes. The shaft of the Probe™ is encased in a stainless steel cannula. An outer plastic sleeve surrounds this stainless steel cannula and an annular gap between the sleeve and the cannula provides a conduit for vacuum-assisted removal of the gaseous products of electrosurgical cutting and any liquids (e.g., blood) that may accumulate at the distal end of the Probe during the biopsy procedure. The vacuum also helps maintain the required cutting arc during automated tissue capture.
The provided text is a 510(k) summary for the Neothermia Corporation's en-bloc Biopsy System™. It discusses the device's intended use and technological characteristics, as well as its substantial equivalence to predicate devices. However, the document does NOT contain information about acceptance criteria, study details, sample sizes, expert qualifications, adjudication methods, or specific performance metrics that would be typically found in a clinical study report.
Therefore, I cannot provide the requested table and study details. The document is primarily a regulatory submission establishing substantial equivalence to existing devices, not a detailed technical report of a new study to prove device performance against specific acceptance criteria.
