Abstract

An apparatus (100) is disclosed for differentially treating a medical device (106). One portion of the device (106) is treated with a first fluid (124) and a separate portion is treated with a second fluid (128). The second fluid (128) is generally substantially different from the first fluid (124). The first fluid (124) can be contacted with a flow region of the medical device (106). The apparatus (100) can include a conduit system (102), where fluid flowing through the conduit system (102) flows through the flow region. Sheet material can be treated differentially on the opposite surfaces of the sheet. The medical device (106) can include vascular tissue.
