Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the audited financial statements and notes thereto included in the Company’s annual report on Form 10-K initially filed with the SEC on February 13, 2015 (the “Annual Report”), as amended. The balance sheet as of December 31, 2014 included in this report has been derived from the audited financial statements included in the Annual Report. In the opinion of management, these financial statements include all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the financial position, results of operations and cash flows for the periods presented. The results of operations for the interim periods shown in this report are not necessarily indicative of the results that may be expected for any future period, including the full year. Items in prior year financial statements have been adjusted to conform with the current year presentation.

Initial Public Offering

In February 2014, the Company completed its initial public offering (“IPO”) in which it issued and sold 1,430,000 shares of its common stock at a public offering price of $7.00 per share. The Company received net proceeds of $7,403 after deducting underwriting discounts and commissions of $848 and other offering expenses of approximately $1,759. The Company incurred $648 of the offering expenses in 2013, and incurred $1,959 of such expenses in the first half of 2014. The Company granted the underwriter an overallotment option to acquire an additional 214,500 shares of its common stock, which expired April 6, 2014 unexercised, and issued the underwriter warrants to acquire an aggregate of 71,500 shares of its common stock at an exercise price of $8.75 per share, which became exercisable February 20, 2015 and expire February 20, 2019. Upon the closing of the IPO, all shares of the Company’s then-outstanding Series A convertible Preferred Stock (1,468,402), Series A-1 convertible Preferred Stock (293,750) and Series A-2 convertible Preferred Stock (250,000) automatically converted into an aggregate of 2,012,152 shares of common stock. In addition, the Company’s then outstanding warrants to acquire an aggregate of 1,067,210 shares of Series A convertible Preferred Stock and 228,656 shares of Series A-1 convertible Preferred Stock were cashlessly exercised at the IPO price for an aggregate of 479,115 shares of common stock. All other outstanding warrants of the Company became exercisable for common stock effective upon the IPO in accordance with their terms.

Going Concern [Abstract]

Going Concern

Going Concern

The Company has incurred recurring losses since inception and expects to continue to incur losses as a result of costs and expenses related to the Company’s marketing and other promotional activities, research and continued development of its product. As of June 30, 2015, the Company has working capital of $850, cash and restricted cash of $4,440 (which includes $2,100 of restricted cash) and stockholders’ equity of $1,698. The Company’s principal sources of cash have included the issuance of equity securities, and to a lesser extent, borrowings under loan agreements and revenue from leasing its product. To increase revenues, the Company’s operating expenses will continue to grow and, as a result, the Company will need to generate significant additional revenues to achieve profitability. In order to execute on its business plan, and given current available cash, the Company anticipates that it will need to raise additional capital.

The Company’s financial statements as of June 30, 2015 have been prepared under the assumption that the Company will continue as a going concern. The Company’s ability to continue as a going concern is dependent upon its ability to obtain additional equity or debt financing, attain further operating efficiencies and, ultimately, to generate additional revenue. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company can give no assurances that additional capital that the Company is able to obtain, if any, will be sufficient to meet the Company’s needs. If the Company is unable to raise additional capital within the next twelve months to continue to fund operations at its current cash expenditure levels, the Company’s operations will need to be curtailed. The foregoing conditions raise substantial doubt about the Company’s ability to continue as a going concern.

The loan agreement provided for customary events of default. This loan was personally guaranteed by a principal stockholder of the Company. This loan agreement was retired in September 2014.

On September 30, 2014, the Company entered into a revolving line of credit with First Republic Bank. Pursuant to the line of credit agreement, the Company may borrow up to $2,000 for a 12-month term that has a variable annual interest rate based on First Republic’s Prime less a spread of 2.0% p.a. The initial interest rate is 1.25% p.a. Under the line of credit agreement, the Company will make monthly payments consisting of $2 of interest, and an annual payment consisting of $2,002 principal plus any accrued interest.

Indemnification Obligations

The Company enters into agreements with customers, partners, lenders, consultants, lessors, contractors, sales representatives and parties to certain transactions in the ordinary course of the Company’s business. These agreements may require the Company to indemnify the other party against third party claims alleging that its product infringes a patent or copyright. Certain of these agreements require the Company to indemnify the other party against losses arising from: a breach of representations or covenants, claims relating to property damage, personal injury or acts or omissions of the Company, its employees, agents or representatives. The Company has also agreed to indemnify the directors and certain of the officers and employees in accordance with the by-laws of the Company. These indemnification provisions will vary based upon the nature and terms of the agreements. In many cases, these indemnification provisions do not contain limits on the Company’s liability, and the occurrence of contingent events that will trigger payment under these indemnities is difficult to predict. As a result, the Company cannot estimate its potential liability under these indemnities. The Company believes that the likelihood of conditions arising that would trigger these indemnities is remote and, historically, the Company had not made any significant payment under such indemnification provisions. Accordingly, the Company has not recorded any liabilities relating to these agreements. In certain cases, the Company has recourse against third parties with respect to the aforesaid indemnities, and the Company believes it maintains adequate levels of insurance coverage to protect the Company with respect to potential claims arising from such agreements.

Stock-Based Compensation

Stock-Based Compensation

The Company’s stock-based compensation program is designed to attract and retain employees while also aligning employees' interests with the interests of its stockholders. Stock options have been granted to employees under the stockholder-approved 2007 Key Person Stock Option Plan (“2007 Plan”) and the stockholder-approved 2014 Stock Incentive Plan (“2014 Plan”). Stockholder approval of the 2014 Plan became effective in September 2014. The 2014 Plan provides that the aggregate number of shares of common stock that may be issued pursuant to awards granted under the 2014 Plan may not exceed 450,000 shares (the “Share Reserve”). However, the Share Reserve automatically increases on January 1st of each year, for a period of not more than 10 years, beginning on January 1st of the year following the year in which the 2014 Plan became effective and ending on (and including) January 1, 2024, in an amount equal to 4% of the total number of shares of common stock outstanding on December 31st of the preceding calendar year. The Company’s Board of Directors may act prior to January 1st of a given year to provide that there will be no January 1st increase in the Share Reserve for such year or that the increase in the Share Reserve for such year will be a lesser number of shares of common stock than would otherwise occur. The Share Reserve is currently 638,640 shares for the year ending December 31, 2015.

In light of stockholder approval of the 2014 Plan, the Company no longer grants equity awards under the 2007 Plan. As of June 30, 2015, 0 shares of an aggregate total of 407,500 shares were available for future stock-based compensation grants under the 2007 Plan and 286,589 shares of an aggregate total of 638,640 shares were available for future stock-based compensation grants under the 2014 Plan.

Aggregate intrinsic value represents the difference between the closing market value as of June 30, 2015 of the underlying common stock and the exercise price of outstanding, in-the-money options. A summary of the Company’s stock option activity and related information for 2015 is as follows:

	Options Outstanding
	Number of Stock Options Outstanding			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (In Years)		Aggregate Intrinsic Value (in thousands)
Balance, January 1, 2015		649,500		$	1.49		7.44	$	474

Exercisable as of June 30, 2015		447,509		$	1.21		5.86	$	948

The total compensation cost related to unvested stock option awards not yet recognized was $456 and $0 as of June 30, 2015 and 2014, respectively. The weighted average period over which the total unrecognized compensation cost related to these unvested stock awards will be recognized is 1.6 years. The total estimated grant date fair value of unvested options was $456 and $0 as of June 30, 2015 and 2014, respectively. The total estimated grant date fair value of options vested during the quarters ended June 30, 2015 and 2014 was $30 and $0, respectively. The total estimated grant date fair value of options vested during the six months ended June 30, 2015 and 2014 was $63 and $0, respectively. The weighted average grant date fair value of options granted during the six months ended June 30, 2015 is $2.10 per share or an aggregate grant date fair value of $263. There were no options granted during the six months ended June 30, 2014.

On January 1, 2015 the Company’s Board of Directors granted an option to acquire an aggregate of 75,000 shares under the 2014 Plan. On May 1, 2015 the Company’s Board of Directors granted options to acquire an aggregate of 50,000 shares under the 2014 Plan. The options from both grant dates vest on a monthly schedule over 48 months such that they are vested in full on the four-year anniversary of the grant date.

Determining the Fair Value of Stock Options

The Company uses the Black-Scholes pricing model to determine the fair value of stock options. The fair value of each option grant is estimated on the date of the grant. The fair value of the options granted is estimated on the date of grant using the Black-Scholes pricing model and the following assumptions for the periods presented:

	Three months ended June 30,				Six months ended June 30,
		2015		2014	2015			2014
Expected term (in years)		5		—		5			—
Risk-free interest rate		1.6	%	—		1.5	%		—
Expected volatility		82.5	%	—		83.3	%		—
Expected dividend rate.		0	%	—		0	%		—

The assumptions are based on the following for each of the years presented:

Valuation Method - The Company estimates the fair value of its stock options using the Black-Scholes option pricing model.

Expected Term - The Company estimates the expected term consistent with the simplified method identified by the SEC. The Company elected to use the simplified method because of its limited history of stock option exercise activity and its stock options meet the criteria of the “plain-vanilla” options as defined by the SEC. The simplified method calculates the expected term as the average of the vesting and contractual terms of the award.

Volatility - Because the Company has limited trading history by which to determine the volatility of its own common stock price, the expected volatility being used is derived from the historical stock volatilities of a representative industry peer group of comparable publicly listed companies over a period approximately equal to the expected term of the options.

Risk-free Interest Rate - The risk-free interest rate is based on median U.S. Treasury zero coupon issues with remaining terms similar to the expected term on the options.

Expected Dividend - The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and therefore, used an expected dividend yield of zero in the valuation model.

Forfeiture - The Company estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting forfeitures and records stock-based compensation expense only for those awards that are expected to vest. All stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. If the Company’s actual forfeiture rate is materially different from its estimate, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period.

The Company has recorded an expense of $30 and $0 as it relates to stock-based compensation for the three months ended June 30, 2015 and 2014, respectively, and an expense of $63 and $0 as it relates to stock-based compensation for the six months ended June 30, 2015 and 2014, respectively, which was allocated as follows based on the role and responsibility of the recipient in the Company:
