Seventh Sense Biosystems says it hopes to file for U.S. and European marketing approval in the 2013 second-quarter for TAP, its point-of-care blood collection device that uses microneedles and doesn't need a vein to do its job. First, however, the Cambridge, MA-based company, which launched in 2008, must complete the registration trial for TAP now under way. If all goes well, Seventh Sense envisions having its CE mark and U.S. regulatory sign-off later this year, with a market launch in 2014. TAP draws blood with microneedles that work through the skin, a one-step process meant to be painless that can also be integrated into diagnostics. Release
