Intended Use

For use In Screening Mammographic Imaging as a Specialty Paddle for Full Breast Compression, as an alternative to conventional breast compression paddles.

Device Story

S.O.F.T. Paddle™ is a specialized compression tray for mammography systems; designed to replace conventional paddles. Device features angled compression plate, sloping downward from chest wall toward nipple; improves anterior breast tissue compression; reduces tissue superimposition; minimizes need for retakes. Used in clinical settings by radiology technicians; attaches to existing mammographic equipment paddle arms or supplied as complete assembly. Device provides improved patient comfort; requires less compression force; increases imaged breast area; enhances contrast resolution. Mechanical device; no electrical components; relies on host mammography system for vertical positioning.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

Constructed from gamma-stabilized LEXAN® or polycarbonate equivalent plastic. Mechanical compression device; no internal energy source; relies on host mammography system for vertical movement. Form factor is a compression tray/paddle designed for retrofit or direct mounting to mammographic equipment. Non-electronic; no software.

Indications for Use

Indicated for patients undergoing screening mammographic imaging requiring full breast compression.

Regulatory Classification

Identification

## AMERICAN MAMMOGRAPHICS S.O.F.T. PADDLE™ (Special Optimized Full Compression Tray)

## 510(k) SUMMARY

While mammography is very sensitive in detecting breast cancer, there are areas of concern. Many patients find mammography very uncomfortable. Breast cancers are frequently missed when located in dense breast tissue, particularly anteriorly. Often, the poor compression of anterior tissue results in film relakes and/or the need for diagnostic studies to distinguish dense tissue from masses. However, most existing full breast compression paddles do not adequately compress the anterior half of the breast: conversely the breast near the chest wall is over-compressed causing patient discomfort and sometimes bruising, Good compression of the breast is necessary to obtain satisfactory mammograms, Good compression reduces breast thickness, shortens exposure time, reduces motion blur, permits use of lower kVp resulting in better contrast resolution and spreads apart breast structures which reduces superimposed structures.

AMERICAN MAMMOGRAPHICS, INC. intends to construct a full breast compression device from gamma stabilized LEXAN® or polycarbonate equivalent plastic currently used in the manufacture of numerous radiological and medical devices. The compression device will readily adapt to existing paddle arms from current OEMs and will also be available as a complete device with compression plate, yoke and mounting arm/shaft; The proposed device is a special octimized full breast compression tray called S.O.F.T. Paddle™ and will allow the targeted area to be imaged accurately, will allow more breast tissue to be imaged, and permit thinning of tissue where it is needed most. The S.O.F.T. Paddle™ proposes to offer full breast coverage with the compression plate set at an angle, downward from the chest wall toward the nipple, for better compression of anterior structures; thus it is a Special Optimized Full Compression Trav . When used for screening views, additional breast tissue can be compressed from the mid-breast to the nipple with improvement to the imaged area.

This compression device is substanially equivalent to those now marketed by several mammographic equipment manufacturers, such as GE, Lorad, Planmed, Instrumentanum, et al. The compression device is normally placed between the x-ray tube and the breast In order to compress the breast tissue and visualize breast structures, both normal and abnormal. The main advantages of S.O.F.T. PADDLE™ are that patient comfort is improved, breast tissue is more adequately compressed due to the design, positioning against the chest wall side is improved, and less compression force is needed. A greater area of breast tissue can be imaged, contrast resolution of the mammogram is improved, and it is adaptable by retrofit to the original equipment manufacturer's current paddle arms or can be supplied as a complete paddle for brand-specific mammography equipment.

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

The compression plate component does not rely on the electrical machinations or rely on the power generated by the machine to accomplish its purpose of compression only. It does not have any impact on the mammographic or x-ray power source. When attached to a paddle/mounting arm the device is dependent upon the electrical power of the mammographic machine to move the compression device up or down, as are all compression paddles for mammography.

The previously issued 510(k) #K903651/B and #K954521 for MammoSpot compression/magnification platforms and MammoSpot Spot Paddle contain applicable equivalent information regarding the efficacy of spot compression both above and below the breast, i.e., a spot cone placed either between the x-ray tube and breast or between the breast and the image receptor and the importance of good breast compression to maximize the quality of a mammooram. Equivalent information reqarding chest wall imaging, anterior breast coverage, and maximized compression is also noted in the previously issued 510(k). For Full Breast mammographic examinations, conventional paddles do not adequately compress the antenor half of the breast causing tissue to be superimposed leading to unnecesary retakes and/or diagnostic work-ups. S;O.F.T. Paddle™ would be used between the x-ray tube and the breast but with a sloped or angled design optimizing the full breast compression for a mammographic examination with equal distribution and better thinning of breast tissue.
