Earnings Per Share [Abstract]
Loss Per Share	Loss Per Share Basic loss per share equals net loss divided by the weighted average common shares outstanding during the period. Diluted loss per share equals net loss divided by the sum of the weighted average common shares outstanding during the period plus dilutive common stock equivalents. The calculation of loss per common share on a basic and diluted basis was the same for the three month periods ended March 31, 2017 and 2016, because the inclusion of dilutive common stock equivalents, the SWK Warrant #1 (as defined in Note 8 to the condensed consolidated financial statements) issued in connection with the Acquisition, and the warrants that were issued beginning on March 2, 2017 (the "2017 Private Offering Warrants") in a private offering to various investors (the "2017 Private Offering") would have been anti-dilutive for all periods presented. The Company has granted options to purchase shares of the Company's common stock through employee stock plans with the weighted average options outstanding as of March 31, 2017 and 2016, of 399,058 and 297,071, respectively, as well as the SWK Warrant #1 to purchase 543,479 shares issued to SWK, and the 2017 Private Offering Warrants to purchase 856,250 shares issued in the 2017 March Private Offering, all of which were outstanding as of March 31, 2017, but are anti-dilutive because the Company is in a net loss position. The 2017 Private Offering Warrants have a strike price of $1.35 per share and are exercisable for a period of four years from the date of issuance but are not exercisable during the first six months after closing of the 2017 Private Offering. The Company issued 1,712,500 shares and 856,250 warrants in the 2017 Private Offering for proceeds of $1.3 million, net of issuance costs. The warrants issued in September 2016 were canceled as part of the 2017 Private Offering.

Loss Per Share

Basic loss per share equals net loss divided by the weighted average common shares outstanding during the period. Diluted loss per share equals net loss divided by the sum of the weighted average common shares outstanding during the period plus dilutive common stock equivalents. The calculation of loss per common share on a basic and diluted basis was the same for the three month periods ended March 31, 2017 and 2016, because the inclusion of dilutive common stock equivalents, the SWK Warrant #1 (as defined in Note 8 to the condensed consolidated financial statements) issued in connection with the Acquisition, and the warrants that were issued beginning on March 2, 2017 (the "2017 Private Offering Warrants") in a private offering to various investors (the "2017 Private Offering") would have been anti-dilutive for all periods presented. The Company has granted options to purchase shares of the Company's common stock through employee stock plans with the weighted average options outstanding as of March 31, 2017 and 2016, of 399,058 and 297,071, respectively, as well as the SWK Warrant #1 to purchase 543,479 shares issued to SWK, and the 2017 Private Offering Warrants to purchase 856,250 shares issued in the 2017 March Private Offering, all of which were outstanding as of March 31, 2017, but are anti-dilutive because the Company is in a net loss position.

The 2017 Private Offering Warrants have a strike price of $1.35 per share and are exercisable for a period of four years from the date of issuance but are not exercisable during the first six months after closing of the 2017 Private Offering. The Company issued 1,712,500 shares and 856,250 warrants in the 2017 Private Offering for proceeds of $1.3 million, net of issuance costs. The warrants issued in September 2016 were canceled as part of the 2017 Private Offering.
