Seventh Sense TM Biosystems TAP 20 Painless Blood Draw Device Rachel Mc. Ateer BME 181

What is it? TAP 20 TM is a TAP (Touch Activated Phlebotomy) device that serves as an alternative to intravenous blood collection. § One-touch process § Approximately 5 cm in diameter § Can hold up to 20 microliters

How does it work? Rather than traditional needles, the device uses 16 microneedles. 1. Device adheres to skin (forearm region) 2. ‘Tap’ process allows micro-needles to penetrate uppermost layers of the skin, collecting capillary blood. A vacuum carries the blood through channels into an internal reservoir 3. After 2 minutes, process is complete and device is removed (a mark resembling a mosquito bite will remain) Samples can be tested on location, or sent to a lab.

Benefits § Designed to increase patient compliance by reducing anxiety and discomfort traditionally associated with blood collection § Portable § Efficient: holds a large enough sample to allow for a wide range of diagnostic tests § Safe testing of HIV and other infectious diseases § Projected to be affordable § Should be commercially available within the next 2 -3 years

Results/Discussion To date, Seventh Sense Biosystems had on-going human testing of their TAP technology, but expects to begin pivotal trials in mid 2013. § In 2011, Seventh Sense Biosystems received the Edison Gold Medal Award § Received a $3. 8 million grant from the Bill & Melinda Gates Foundation § TAP 100 TM (holding up to 100 microliters) is in the works § The company hopes to improve the device to perform other tasks such as delivering insulin
