Used by clinicians for breast duct procedures. Device enables simultaneous infusion and collection, combining functions of predicate needles. Sterile, single-use device.

Clinical Evidence

Clinical testing conducted on pre-mastectomized or lumpectomized breasts to evaluate human use. Preclinical testing performed using human cadaver model. Laboratory testing evaluated performance parameters compared to predicates. Results supported safety and effectiveness for intended use.

Technological Characteristics

Dual-lumen flexible shaft; proximal hub with two ports; distal tip with 1 cm marker. Sterile, single-use. No electronic components or software.

Indications for Use

Indicated for patients requiring contrast-enhanced radiography of breast milk ducts or collection of cells/fluid for cytological analysis.

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 Preparation Date October 30, 1998

Device Names Trade Name: Windy Hill Technology Fuji Catheter Common Name: Breast Duct Catheter Classification Name: Manual Surqical Instrument (21CFR § 878.4800)

#### Substantially Equivalent Devices

Substantial Equivalence was claimed to the Manan™ Galactography Kit, the Manan™ Chiba Needle and the Manan™ Acura Breast Localization Needle.

#### Device Description

The Windy Hill Technology Fuii Catheter is a dual lumen device with a flexible shaft. The hub located at the proximal end of the Fuii Catheter has two branches which each correspond with a single port. The entry port is used for saline or contrast infusion and is marked with an arrow pointing in the distal direction of the catheter. The corresponding entry lumen is located at the distal end of the catheter, adjacent to the 1 cm marker. The exit port is used for fluid collection and for quidewire introduction and is marked with an arrow pointing in the proximal direction of the catheter. The corresponding exit lumen is located at the distal tip of the catheter. The device is provided sterile and is intended for single use only.

### Intended Use

The Windy Hill Technology Fuji Catheter is designed to perform contrast enhanced radiography of breast milk ducts. It may also be used for the collection of cells and/or fluid for cytological evaluation.

### Technological Characteristics

The Windy Hill Technology Device is substantially equivalent to the Manan™ Galactography Kit, the Manan™ Chiba Needle and the Manan™ Acura Breast Localization Needle. The main difference between the subject and predicate devices is that the WHT device contains two device lumens which combines the functions of the predicate devices to allow for fluid infusion and fluid collection.

### Data Supporting Substantial Equivalence

WHT conducted laboratory, preclinical and clinical testing to demonstrate the safe and effective use of the WHT Device. Laboratory testing was conducted to evaluate specific device performance parameters and, in some cases, to compare these results with those obtained with a predicate device. Performance was also evaluated in preclinical testing using a human cadaver model. Clinical testing was conducted to evaluate human use of the device in pre-mastectomized or lumpectomized breasts. This testing supported that use of the Windy Hill Technology Fuji Catheter 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 (OS) 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.
