You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" {1}------------------------------------------------ (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Real time aging is being performed on Vista BC Putty to support shelf life during typical storage conditions. - Transit Testing ● - o This test confirms that the packaging configurations are sufficient and withstand simulated transit conditions. Moreover, the products performed satisfactory post-transit, which confirms that transit did not have a negative effect on the products themselves. - Microbiological Testing ● - Contamination risks from manufacturing are mitigated as Vista BC Putty exhibits o antimicrobial properties. Furthermore, these results help to support shelf stability and multiple use of non-patient contacting materials, such as the svringes, as any introduced microbes will not remain viable within the medical device. - Cytotoxicity Testing ● - Vista BC Putty was found to yield better cytotoxicity results compared to the reference O device, Vista BC Sealer. #### Clinical Performance Testing and Compliance 8. Clinical performance is not deemed necessary. #### Conclusion 9. Vista BC Putty is to be marketed by Inter-Med, Inc., 2200 South St., Racine, WI 53404, and is substantially equivalent to MTA 2.3 (Design 2) (K181917).
