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.

AI/ML Overview

The provided text is a 510(k) summary for Neothermia Corporation's en-bloc Biopsy System™. It discusses the device's intended use and technological characteristics, as well as its substantial equivalence to previously cleared predicate devices. However, it does not include information about specific acceptance criteria or a study that proves the device meets those criteria.

Therefore, I cannot fulfill your request for the detailed table and study information as the provided document does not contain acceptance criteria or study results.

The document is purely a regulatory submission declaring substantial equivalence to predicate devices, which means it argues that the new device is as safe and effective as existing legally marketed devices, rather than presenting new performance data against specific criteria.

Predicate Devices

Neothermia Corp.'s en-bloc Biopsy System™

Intended Use

The en-bloc Biopsy System is intended for diagnostic sampling of breast tissue during a breast biopsy procedure.

Technological Characteristics

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.

Substantial Equivalence

The modified probe has the same intended use, principles of operation, and technological characteristics as the previously cleared predicate devices. The modified device and its predicate devices are both electrosurgical devices used to biopsy breast tissue. The change does not raise new questions of safety or efficacy. The modified probe is substantially equivalent to Neothermia's cleared en-bloc probes.

Dear Ms. Coval-Goldsmith:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
