Intended Use

The Gel Mark UltraCor Biopsy Site Marker is indicated for use to radiographically mark breast tissue during a percutaneous breast biopsy procedure.

Device Story

Device consists of 17 Ga disposable beveled needle applicator containing two resorbable polylactic acid/polyglycolic acid pellets, one gold marker, and one polyethylene glycol (PEG) plug. Gold marker provides long-term radiographic visibility; pellets provide short-term ultrasound visibility (approx. 4 weeks) and resorb in approx. 12 weeks. Applicator features 20 cm needle with 1 cm depth marks and locking plunger. Used by clinicians during percutaneous breast biopsy to mark tissue site. Output is permanent radiographic marker and temporary ultrasound-visible pellets. Benefits include precise localization of biopsy site for follow-up imaging or surgical planning.

Clinical Evidence

Bench testing only. Preclinical testing confirmed radiographic visibility of the gold marker.

Technological Characteristics

17 Ga beveled needle applicator; gold marker; resorbable polylactic acid/polyglycolic acid pellets; polyethylene glycol (PEG) plug. Metallic applicator shaft. Manual deployment via locking plunger. Non-powered, mechanical implant.

Indications for Use

Indicated for radiographic marking of breast tissue in patients undergoing percutaneous breast biopsy procedures.

Regulatory Classification

Identification

| Description | The Gel Mark UltraCor Breast Biopsy Marker consists of a 17 Ga disposable beveled<br>needle Applicator containing:<br>2 resorbable polylactic acid/polyglycolic acid pellets. 1 gold marker in the center position. 1 polyethylene glycol (PEG) plug in the needle bevel. The gold marker is intended for long-term radiographic marking of the tissue site. The<br>pellets are visible via ultrasound for approximately 4 weeks and are essentially resorbed<br>in approximately 12 weeks.<br>The Applicator has a beveled 20 cm needle with 1 cm depth marks and a locking<br>plunger. The pellets are deployed from the beveled needle tip into the tissue site. |
| Indications for use | The Gel Mark UltraCor Biopsy Site Marker is indicated for use to radiographically<br>mark breast tissue during a percutaneous breast biopsy procedure. |
| Summary of substantial<br>equivalence | The Gel Mark UltraCor Biopsy Site Marker as the following similarities to the<br>previously cleared predicate devices:<br>Same indications for use; Same intended treatment site; Same operating principle; and Same basic design. Preclinical testing had confirmed the radiographic visibility of the gold marker. Gold, as<br>a long-term implant, has an extensive history of use and has been cleared for use in a<br>similar application. The resorbable polyethylene glycol plug has been used previously<br>in SenoRx biopsy site markers to contain pellets in the applicator. The change to a<br>metallic (stainless steel) applicator shaft is similar to the metallic (titanium) of a<br>previous cleared SenoRx device. The reduction in the applicator shaft diameter varies<br>in a manner that has no impact on device safety.<br>In summary, the Gel Mark UltraCor Biopsy Sire Marker as described in this submission<br>is substantially equivalent to the predicate devices. |

Dear Mr. Mazzarese:

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.
