# DESCRIPTION OF DEVICE

The Microvasive UltratomeRX is a triple lumen sphincterotome. The UltratomeRX is capable of accepting a .035” guidewire in one open channel while simultaneously injecting or cutting in another lumen. The open channel allows for the quick exchange of a guidewire completely isolated from injection agents and cutting. No stylet is necessary for scope passage.

The UltratomeRX is indicated for use in transendoscopic sphincterotomy of the Papilla of Vater and/or the Sphincter of Oddi. The Microvasive UltratomeRX can also be used to cannulate and inject contrast medium.

## DESCRIPTIVE AND TECHNOLOGICAL CHARACTERISTICS OF PROPOSED AND PREDICATE DEVICES

Boston Scientific Corporation believes that the UltratomeRX is substantially equivalent to the currently-marketed Boston Scientific Ultratome XL. The major components of the UltratomeRX are the catheter shaft, cutting wire, handle, guidewire introducer, and outer sheath. A thorough comparison of the descriptive characteristics between the UltratomeRX and the predicate device shows equivalence.

## PERFORMANCE CHARACTERISTICS

Laboratory testing regarding characteristics was performed on the UltratomeRX to verify its safety and performance. A biocompatibility assessment was performed on the patient- and fluid-contact materials of the UltratomeRX with satisfactory results.

## CONCLUSION

Boston Scientific Corporation believes that UltratomeRX is substantially equivalent to the currently-marketed UltratomeRX. A comparison of the descriptive characteristics of these products demonstrate the UltratomeRX is equivalent in its indications for use, while being very similar in design and materials. In addition, Boston Scientific Corporation has presented laboratory testing and biocompatibility information. The information presented provides assurance that the UltratomeRX will meet the minimum requirements that are considered acceptable for its intended use.
