"Failure to
establish and maintain procedures
for the identification, documentation, validation, or where appropriate verification, review, and approval of design changes before their implementation, as required by 21 CFR 820.30(i). Specifically: a) In June 2006, your firm recalled 2455 units of the Spectrum Infusion Pump due to several events where the pump tubing mis-loaded when it was installed by the end user. Several design changes were made to the Spectrum Pump's hardware and software to better assist the end user in installing the pump tubing. These design changes were incorporated into the blanket Engineering Change Notice (ECN # 15501). This ECN contained several individual ECNs to cover each change that was made to correct the tubing mis-loading problem. However, the blanket ECN also included an individual ECN to implement the PCA/PCEA delivery modes within the Spectrum pump. ECN# 15501 and all individual ECNs under this blanket ECN were cleared for manufacturing on May 01, 2006. However, our inspection revealed the
software verification/validation
for the pump operating software version 4.00.04 and MDL software version 5, and the design of the hardware components associated with the PCA/PCEA module were not completed at the time the re-designed Spectrum pump was released for manufacturing. Yet, ECN # 15501 was approved for manufacturing by your firm's Approval Committee (consisting of representatives from Engineering, Manufacturing, Quality Assurance and Purchasing), without ensuring that the appropriate verification/validation for the PCA/PCEA functions were completed. More significantly, 257 units of the Spectrum pumps, manufactured between May 01, 2006, and June 26, 2006, were distributed into interstate commerce with an "enabled" version of this unvalidated PCA/PCEA function as replacements for defective devices that were returned to Sigma International as a result of the June 2006 recall."
