Revenue Recognition [Abstract]
Revenue Recognition	(3) Revenue Recognition In the United States the Company sells its products and services directly to hospitals and clinics. Revenue is recognized in accordance with generally accepted accounting principles as outlined in ASC 605-10-S99, which requires that four basic criteria be met before revenue can be recognized: (i) persuasive evidence of an arrangement exists; (ii) the price is fixed or determinable; (iii) collectibility is reasonably assured; and (iv) product delivery has occurred or services have been rendered. The Company recognizes revenue as products are shipped based on FOB shipping point terms when title passes to customers. The Company negotiates credit terms on a customer-by-customer basis and products are shipped at an agreed-upon price. All product returns must be pre-approved and, if approved, customers are subject to a 20% restocking charge. In all international markets, the Company sells its products to international distributors which subsequently resell the products to hospitals and clinics. The Company has agreements with each of its distributors which provide that title and risk of loss pass to the distributor upon shipment of the products to the distributor. The Company warrants that its products are free from manufacturing defects at the time of shipment to the distributor. Revenue is recognized upon shipment of products to distributors following the receipt and acceptance of a distributor's purchase order. Allowances are provided for estimated returns and warranty costs at the time of shipment. The Company also generates revenues from license agreements and recognizes the revenue when earned. In accordance with ASC 605, for revenues which contain multiple deliverables, the Company separates the deliverables into separate accounting units if they meet the following criteria: (i) the delivered items have a stand-alone value to the customer; (ii) the fair value of any undelivered items can be reliably determined; and (iii) if the arrangement includes a general right of return, delivery of the undelivered items is probable and substantially controlled by the seller. Deliverables that do not meet these criteria are combined with one or more other deliverables into one accounting unit. Revenue from each accounting unit is recognized based on the applicable accounting literature, primarily ASC 605-10-S99. Starting in January 2012, the Company began to generate revenue from selling a reprocessing service for ClosureFast® radiofrequency catheters. In accordance with ASC 605-45, the Company recognizes this revenue gross, with the amount paid to the supplier of the reprocessing service reflected as cost of sales. In accordance with ASC 605-45-45, the Company includes shipping and handling revenues in net revenue, and shipping and handling costs in cost of sales.
