Intended Use

The EnCor Breast Biopsy System is indicated to provide breast tissue samples for diagnostic sampling of breast abnormalities. It is intended to provide breast tissue for histologic examination with partial or complete removal of the imaged abnormality. It 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 palpated 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 through clinical and/or radiological criteria (e.g. fibroadenoma, fibrocystic lesion), the EnCor Breast Biopsy System may also be used to partially remove such palpable lesions. Whenever breast tissue is removed, histological 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.

Device Story

EnCor Breast Biopsy System; vacuum-assisted biopsy device; provides tissue samples for histologic examination. Inputs: breast tissue via biopsy probe. Operation: partial or complete removal of imaged or palpable breast abnormalities. Output: tissue samples for pathology. Used in clinical settings by healthcare providers. Enables diagnostic sampling and partial excision of benign lesions. Benefits: facilitates histological evaluation of breast abnormalities.

Clinical Evidence

No clinical data provided; substantial equivalence based on design, materials, and technological characteristics.

Technological Characteristics

Breast biopsy system utilizing 7 and 10-Gauge biopsy probes. Vacuum-assisted tissue acquisition. Materials are identical to predicate devices. No software or electronic algorithm details provided.

Indications for Use

Indicated for patients requiring diagnostic breast tissue sampling of imaged or palpable breast abnormalities, including partial removal of benign palpable lesions (e.g., fibroadenoma, fibrocystic lesions).

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.

Summary of substantial equivalence

The EnCor Breast Biopsy System with its 7 and 10-Gauge biopsy probes has the following similarities with the predicate devices: same intended use; same design; same patient contacting materials; same operating principle; and same technological characteristics.

Therefore, the EnCor Breast Biopsy System with its 7 and 10-Gauge probes has the same capability of partial removal of palpable masses as does using either of the predicate devices.

- It 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 palpated 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 through clinical and/or radiological criteria (e.g. fibroadenoma, fibrocystic lesion), the EnCor Breast Biopsy System may also be used to partially remove such palpable lesions.
