Subsequent Events [Abstract]
Subsequent Events	(12) Subsequent Events Subsequent to the end of the third quarter through November 4, 2014, the Company sold approximately 0.3 million shares of its common stock under the March 2013 Sales Agreement through an “at the market” equity offering program for net proceeds of approximately $0.4 million. The shares were issued pursuant to an effective registration statement on Form S-3 (333-187230). The net proceeds will be used for general corporate purposes, including, but not limited to, funding of the Company’s clinical trials, commercialization of our products, obtaining regulatory approvals, capital expenditures and working capital. As of November 4, 2014, the Company has approximately $40.0 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.
