Intended Use

The DucPrep Breast Aspirator device is used to elicit fluid from multiple ductal orifices for subsequent cytological evaluation and/or to identify ductal orifices for subsequent cannulation with the WHT Fuji Catheter.

Device Story

The DucPrep Breast Aspirator is a manual, non-powered device used to express breast ductal fluid. It consists of a rigid polycarbonate cup with a flexible silicone insert placed over the nipple, connected via polymer tubing to a standard syringe. The operator (clinician) manually manipulates the syringe to create a gentle vacuum, drawing fluid from multiple ductal orifices. The collected fluid is intended for subsequent cytological evaluation or to assist in identifying orifices for cannulation with the WHT Fuji Catheter. The device is used in a clinical setting to facilitate diagnostic procedures.

Clinical Evidence

Clinical testing was conducted to evaluate human use of the device in human subjects. The study demonstrated that the device is safe and effective for its intended use of eliciting breast ductal fluid.

Technological Characteristics

Device consists of a rigid polycarbonate cup, flexible silicone insert, and polymer tubing. Operates via manual vacuum generation using a standard syringe. Non-powered, manual device. Packaged in a Tyvek pouch.

Indications for Use

Indicated for use in women to elicit breast ductal fluid for cytological evaluation or to identify ductal orifices for cannulation.

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.

Predicate Devices

• Diagnostic, Inc. Breast Aspirator
• WHT Fuji Catheter
• nonpowered breast milk pumps

#### Substantially Equivalent Devices

Substantial Equivalence was claimed to the Diagnostic, Inc. Breast Aspirator, the WHT Fuji Catheter and nonpowered breast milk pumps.

#### Device Description

The Windy Hill Technology DucPrep breast aspirator device is similar to nonpowered breast pumps used to express mill in lactating women. The device is comprised of a rigid polycarbonate cup which is connected to a small piece of polymer tubing. A flexible, silicone insert is placed inside of the rigid polycarbonate cup prior to device placement around the breast nipple. The tubing is attached to a standard syringe which is used to pull a gentle vacuum to express breast ductal fluid. The device is packaged in a Tyvek® pouch.

## Intended Use

The DucPrep device is used to elicit fluid from multiple ductal orifices for subsequent cytological evaluation or to identify ductal orifices for subsequent cannulation with the WHT Fuii Catheter.

## Technological Characteristics

The DucPrep device is substantially equivalent to the Diagnostic, Inc. Breast Aspirator, the WHT Fuji Catheter and nonbowered breast milk pumps. The subject device differs from the WHT Fuji Catheter in that the latter device is a catheter, as opposed to a pump, and allows for the collection of breast ductal fluid from individual ductal orifices. The DucPrep device shares similar design, material and operating characteristics as the Diagnostic, Inc. Breast Aspirator and nonpowered breast pumps. The subject device and these two predicate devices (i.e., the Diagnostic, Inc. Breast Aspirator and nonpowered breast pumps) are comprised of polymer cups which are placed over the breast nipple and are used in conjunction with a nonpowered mechanism for applying a gentle vacuum enabling fluid expression.

## Data Supporting Substantial Equivalence

WHT conducted laboratory and clinical testing to demonstrate the safe and effective use of the WHT Device. Laboratory testing was conducted to evaluate specific device performance parameters. Clinical testing was conducted to evaluate human use of the device in human

subjects. This testing supported that use of the Windy Hill Technology DucPrep Breast Aspirator is both safe and effective for its intended use.

Dear Ms. Soito:

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. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
