Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Please see Note 2 to our Consolidated Financial Statements included in the Company’s Form 10-K for the fiscal year ended December 31, 2013, for a description of all significant accounting policies. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Accounts Receivable Accounts receivable represent amounts due from customers for which revenue has been recognized. Generally, the Company does not require collateral or any other security to support its receivables. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing receivables. The Company determines the allowance based on factors such as historical collection experience, customers' current creditworthiness, customer concentrations, age of accounts receivable balance and general economic conditions that may affect the customers' ability to pay. Inventories Inventory is valued at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of market value. We assess the valuation of our inventory on a periodic basis and make adjustments to the value for estimated excess and obsolete inventory based on estimates about future demand. The excess balance determined by this analysis becomes the basis for our excess inventory charge. Our excess inventory review process includes analysis of sales forecasts, managing product rollovers and working with operations to maximize recovery of excess inventory. Revenue Recognition The Company sells its products through a combination of a direct sales force and independent stocking distributors and representatives in the U.S. and independent distributors in international markets. The Company recognizes revenue when title to the goods transfers to customers, provided there are no material remaining performance obligations required of the Company or any matters of customer acceptance. In cases where the Company utilizes distributors or ships product directly to the end user, it recognizes revenue upon shipment provided all revenue recognition criteria have been met. A portion of the Company's revenue is generated from inventory maintained at hospitals or with the field representatives. For these products, revenue is recognized at the time the product has been used or implanted. The Company records estimated sales returns, discounts and allowances as a reduction of net sales in the same period revenue is recognized. Patent Costs The Company incurs certain legal and related costs in connection with patent applications for tissue based products and processes. The Company capitalizes such costs to be amortized over the expected life of the patent to the extent that an economic benefit is anticipated from the resulting patent or alternative future use is available to the Company. The Company capitalized approximately $168,000 of patent costs during the first three months of 2014. There were not any patent costs capitalized for the three months ended March 31, 2013. Recent Accounting Pronouncements The Company considers the applicability and impact of all ASUs. For the three months ended March 31, 2014, and through the date of this report, all ASUs issued, effective and not yet effective, were assessed and determined to be either not applicable or are expected to have minimal impact on our financial position or results of operations.
