Intended Use

SiteSelect is a disposable, single use, diagnostic device used to obtain localized large core biopsies of breast tissue of a mammographic abnormality, identified by the placement of a needle/ localization wire, which is suspect to be malignant. The SiteSelect device is intended to provide tissue for histological examination with partial or complete removal of imaged lesions. The scope of a histological abnormality is not able to be determined from it's mammographic appearance. Therefore, it is essential that the tissue margins be examined for margin involvement and completeness of removal in cases where the tissue sample is not found to be benign. SiteSelect is to be used in conjunction with stereotactic mammographic imaging systems capable of determining position of lesion within breast tissue. This device is used in conjunction with the SiteSelect Instrument Accessories, which are mounted on a stereotactic table and used with a stereotactic mammographic imaging system.

Device Story

Disposable, single-use breast biopsy device; used with stereotactic mammographic imaging systems and instrument accessories mounted on stereotactic tables. Device obturates to lesion site to obtain large core tissue samples for histological examination; allows partial or complete removal of imaged lesions. Unlike ABBI devices, SiteSelect leaves tissue in route to target area intact. Used in clinical settings by healthcare professionals. Provides tissue samples for pathology; enables diagnosis of malignant lesions and assessment of margin involvement.

Clinical Evidence

Multi-center, non-randomized study of 87 patients across 3 sites. Evaluated device for removal of mammographically detected abnormalities. 12 patients (14%) diagnosed with malignant lesions; 16.7% had negative margins, 58.3% had margin involvement, 25% undetermined. All malignancies followed by surgical procedure.

Technological Characteristics

Disposable, single-use biopsy device. Materials and construction identical to predicate. Sterilization: Ethylene Oxide (EtO) per ANSI/AAMI/ISO 11135-1994. Biocompatibility per ISO 10993. Risk analysis per EN 1441. Packaging per ISO 11607. Mechanical operation via stereotactic table mounting.

Indications for Use

Indicated for patients requiring diagnostic large core biopsy of mammographically detected breast abnormalities suspected of malignancy.

Regulatory Classification

Identification

A gastroenterology-urology biopsy instrument is a device used to remove, by cutting or aspiration, a specimen of tissue for microscopic examination. This generic type of device includes the biopsy punch, gastrointestinal mechanical biopsy instrument, suction biopsy instrument, gastro-urology biopsy needle and needle set, and nonelectric biopsy forceps. This section does not apply to biopsy instruments that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.

#### Appendix II

#### Summary of Safety and Effectiveness

The SiteSelect device, a disposable breast biopsy device, is substantially equivalent to like devices in commercial distribution. These devices are marketed by Imagyn Surgical and United States Surgical Corporation (USSC).

SiteSelect, Imagyn Surgical, and USSC devices are all used to obtain biopsies within breast tissue. These devices are used in conjunction with instrument accessories which are used to mount the devices on a stereotactic table. These devices are used with stereotactic mammographic imaging systems.

The construction, materials, sterilization, and method of operation of the SiteSelect devices are identical to the Imagyn Surgical SiteSelect devices currently on the market.

The major difference between SiteSelect and USSC ABBI devices is that the ABBI device removes tissue in route to and including the target area. The SiteSelect device obturates up to the lesion, leaving intact the tissue in route to the target area.

Standards/guidelines used for the testing and manufacturing of the SiteSelect device are:

ANSI/AAMI/ISO 11135-1994 Medical Devices - Validation and routine control of ethylene oxide sterilization ANSI/AAMI/ISO 11135-1994 Medical Devices -Validation and routine control of ethylene oxide sterilization

ISO 10993-7: 1995 EtO Sterilization Residuals; for Limited Exposure Devices

### Summary of Safety and Effectiveness (continued)

Clinical Summary:

Data from a multi-center, non-randomized study was collected. Eighty-seven patients, from 3 sites, underwent SiteSelect stereotactic breast biopsy procedures to evaluate device for the use in the removal of mammographically detected abnormalities for diagnostic evaluation.

Twelve patients (14%) were diagnosed with malignant lesions. Of the 12 patients with malignant lesions 2 (16.7%) had negative margins, 7 (58.3%) had margin involvement, and 3 (25%) were undetermined. Consistent with standard of care for excisional biopsies, all patients with malignancies were treated with a surgical procedure after diagnostic SiteSelect procedure.

Dear Ms. Powell:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions.
