Intended Use

The kit is intended to improve the performance of the compression system of the GE Senographe 600T series x-ray mammography systems. It is designed to position the compression paddles flat and parallel with the bucky surface and to give the technologist a smoother method for applying "fine adjustment" compression force. It is not intended to change the basic operation of the compression system, the operator controls, or the amount of compression force applied to the breast. The kit does not change the compression release features in any way.

Device Story

Accessory kit for GE Senographe 600T mammography systems; modifies existing compression hardware. Comprised of two components: an electrical circuit module for smoother fine-adjustment compression force application and aluminum spacers to eliminate a 1.2-degree paddle tilt, ensuring the paddle remains flat and parallel to the bucky surface. Used in clinical mammography settings by radiology technologists. Does not alter basic system operation, compression force limits, or safety release mechanisms. Benefits patient by improving compression uniformity and control during imaging.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Consists of an electrical circuit module for compression control and aluminum spacers for paddle alignment. Designed specifically for GE Senographe 600T series. Modifies mechanical paddle orientation (removes 1.2-degree tilt) and electrical control sequence for fine adjustment. No software or digital processing involved.

Indications for Use

Indicated for use as an accessory to GE Senographe 600T series x-ray mammography systems to improve compression paddle positioning and fine adjustment control during mammographic procedures.

Regulatory Classification

Identification

### Legally marketed device to which we are claiming equivalence:

The device to which substantial equivalence is being claimed is the GE Senographe 600T and 600Ts. X-ray mammography systems. The 510(k)document control number for this comparison device is K881882.

### Description of Device

The Digitec Two Stage Compression Kit is an accessory item designed for use in the GE Senographe 600T series X-Ray Mammography Systems. It is comprised of two parts:

- 1) Compression Control Module
The compression control module is a small electrical circuit added to the original compression control system. It modifies the system to give the technologist a smoother method for applying "fine adjustment" compression force.

{1}------------------------------------------------

- 2) Paddle Leveling Spacers
The leveling spacers are used to change the position of the compression paddles relative to the bucky surface. The spacers are small aluminum pieces designed to fit on the compression paddle mounting arms. The spacers remove the 1.2 degree tilt of the original design and reposition the paddles flat and parallel with the surface of the bucky.

#### Intended Use of The Digitec Two Stage Compression Kit

The kit is intended to improve the performance of the compression system of the GE Senographe 600T series x-ray mammography systems. It is designed to position the compression paddles flat and parallel with the bucky surface and to give the technologist a smoother method for applying "fine adjustment" compression force.

It is not intended to change the basic operation of the compression system, the operator controls, or the amount of compression force applied to the breast. The kit does not change the compression release features in any way.

Dear Mr. McGinty:

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 legally marketed predicate 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). Vou 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 III (Special Controls) or dass 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 requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General requlation (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.

# STATEMENT OF INDICATIONS OF USE

The Digitec Two Stage Compression Kit is a modification for the GE Senographe 600T series x-ray mammography systems. It modifies two aspects of the compression system.

First, the kit is intended to improve the "fine adjustment" control of the compression sequence. The original design of the compression system uses the same control method for applying initial compression force and for "fine adjustment" force. The kit does not change the method to apply initial compression force. It modifies the control sequence to achieve smoother fine adjustment control. "Fine adjustment" control is required to slowly and incrementally add the last little bit of compression just prior to making the exposure.

The modification kit also repositions the compression paddle to be flat and parallel with the breast support plate. The original design elevates the chestwall edge of the compression paddle off of the breast support plate. The kit removes the 1.2-degree tilt of the original design.

The kit is not intended to change the basic operation of the compression system, the operator controls, or the amount of compression force applied to the breast. Finally, the kit does not change the safety or compression release features in any way.
