Subsequent Events [Abstract]
Subsequent Events	Note 10: Subsequent Events During the third quarter through August 8, 2012, the Company sold approximately 1.2 million shares of our common stock under the Sales Agreement through an "at the market" equity offering program for net proceeds of approximately $2.5 million. The net proceeds will be used for general corporate purposes, including, but not limited to, commercialization of our products, obtaining regulatory approvals, funding of our clinical trials, capital expenditures and working capital. As of August 8, 2012, the Company has approximately $31.0 million remaining under the program. The Company completed an evaluation of the impact of any subsequent events through the date financial statements were issued and determined there were no other subsequent events requiring disclosure in or adjustment to these financial statements.
