Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On August 8, 2017, the Company entered into a First Amendment to the A&R Credit Agreement (the “First Amendment”) that provided for an additional $2.0 million term loan (the “August 2017 Term Loan”). The Company was required to repay the August 2017 Term Loan by February 1, 2018. In consideration for the First Amendment, the Company issued a new warrant (the “August Warrant”) for SWK to purchase up to 450,000 shares of the Company’s common stock for a strike price of $0.80 per share, paid a fee of $0.03 million, and will pay an exit fee of $0.28 million. On November 14, 2017, the Company entered into a Second Amendment to the A&R Credit Agreement, which provided a waiver for the non-compliance with the debt covenants for the measurement period ended September 30, 2017. On February 2, 2018, the Company entered into a Third Amendment to the A&R Credit Agreement which provided a waiver for the non-compliance of the debt covenants for the measurement period ended December 31, 2017, if the Company is able to pay in full the $2.0 million due under the August 2017 Term Loan prior to April 30, 2018. The Company was not able to make its March 15, 2018, payment to SWK due under the A&R Credit Agreement; therefore, the Company is in default with SWK and, due to the cross-default clause with CNH, was also in default on the 2016 Credit and Security Agreement. In addition, the Company's Subordinated Promissory Note owed to Century is subject to acceleration in the event of defaults on the A&R Credit Agreement and 2016 Credit and Security Agreement. Due to the covenant violations, events of default, and the substantial doubt about the Company's ability to continue as a going concern, all debt has been classified as short-term on the consolidated balance sheet as of December 31, 2017. On March 26, 2018, as previously disclosed on the Company's Current Report on Form 8-K filed with the SEC on March 30, 2018, the Company appointed a Chief Restructuring Officer ("CRO"), whose principal duties in the immediate term are to establish a working capital plan, with the broader mandate to include developing and implementing plans to restructure the Company’s balance sheet, operating expense structure and overall strategies in an effort to resolve the substantial doubt about the Company's ability to continue as a going concern, as described in Note 2 to the condensed consolidated financial statements.
