Intended Use

The Presto Breast Biopsy Device is intended for diagnostic sampling of breast tissue during breast biopsy procedures. It is to be used for diagnostic purposes only and is not intended for therapeutic uses. The Presto Breast Biopsy Device is indicated to provide breast tissue samples for diagnostic sampling of breast abnormalities. It is designed to provide breast tissue for histologic examination with partial or complete removal of the imaged abnormality. The extent of histologic abnormality cannot be reliably determined from its mammographic appearance. Therefore, the extent of removal of the 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.

Device Story

Sterile, single-use percutaneous biopsy device; stainless steel coring cannula with razor edge; stationary internal coil. Handle contains actuation button, sample collection chamber, DC motor. Powered by external reusable medical-grade AC/DC power supply (12V). Operator-controlled; button press rotates cannula to core and transport tissue to collection chamber. Compatible with coaxial introducer. Used in clinical settings for diagnostic sampling of breast abnormalities; provides tissue for histologic examination. Benefits patient by enabling minimally invasive tissue acquisition for diagnosis.

Clinical Evidence

Bench testing only. Studies included in-vitro device performance, electrical and product safety (IEC 60601-1), tensile strength, fatigue, biocompatibility, and simulated use testing.

Technological Characteristics

Stainless steel coring cannula; echogenic working-end. Powered by external 12V AC/DC power supply. Single-use disposable device with reusable power source. Sterile. No software/algorithm.

Indications for Use

Indicated for diagnostic sampling of breast tissue abnormalities in patients requiring histologic examination. Not for therapeutic use.

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.

## Table 2.1 Predicate Device Information

#### Device Description:

The Presto Breast Biopsy Device is a sterile, single-use percutaneous biopsy device. The working end of the device includes a stainless steel coring cannula with a razor edge and a stationary coil located within the coring cannula. The handle of the device contains an actuation button, a sample collection chamber, a drive mechanism for rotating the coring cannula and a DC power jack for a 12V input. A reusable, medical grade AC/DC power supply provides 12V to the disposable device. Depressing the button on the handle rotates the coring cannula - allowing the operator to core and transport tissue samples to the collection chamber. The device may be used with a coaxial introducer.

### Intended Use:

The Presto Breast Biopsy Device is intended for diagnostic sampling of breast tissue during breast biopsy procedures. It is to be used for diagnostic purposes only and is not intended for therapeutic uses.

The Presto Breast Biopsy Device is indicated to provide breast tissue samples for diagnostic sampling of breast abnormalities. It is designed to provide breast tissue for histologic examination with partial or complete removal of the imaged abnormality.

The extent of histologic abnormality cannot be reliably determined from its mammographic appearance. Therefore, the extent of removal of the 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.

## Device Comparison:

The Presto Breast Biopsy device shares many similarities with one or all of the predicate devices, including:

- . Similar indications for use and anatomical target site;
- Similar features, including: .
- Single, Insertion -Multiple Sample functionality 0
- One-button user-interface 0
- Compatibility with coaxial introducer 0
- 0 Echogenic working-end;
- Similar materials the working end of all devices is predominantly stainless steel; and ●
- . Similar device functionality - a reusable, medical grade AC-DC power supply powers a DC motor which spins a forward advancing, spinning cannula to core & severe the targeted specimen.

#### Testing Summary:

The Presto Breast Biopsy Device was evaluated in the following non-clinical studies: in-vitro device performance, electrical & product safety (IEC 60601-1), tensile strength & fatigue, biocompatibility, predicate device comparison and simulated use testing.

Results of the testing demonstrate that the materials, manufacturing process and design of the Presto Breast Biopsy Device meet the established specifications necessary for consistent performance during its intended use

#### Conclusion:

Based on the intended use, product, and performation provided in this notification, the subject device has been shown to be substantially equivalent to the currently marketed and unmodified predicate devices.
