Commitments and Contingencies [Abstract]
Commitments and Contingencies	(9) Commitments and Contingencies Governmental Proceedings On June 28, 2011, the Company received a subpoena from the U.S. Attorney's Office for the Western District of Texas under the Health Insurance Portability & Accountability Act of 1996 (HIPAA) requesting the production of documents related to the Company's Vari-Lase products, and in particular the use of the Vari-Lase® Short Kit for the treatment of perforator veins. The Vari-Lase Short Kit has been sold under a 510(k) clearance for the treatment of incompetence and reflux of superficial veins in the lower extremity since 2007 with total U.S. sales through September 30, 2012 of approximately $432,000 (0.1% of the Company's total U.S. sales) and has not been the subject of any reported serious adverse clinical event. On August 14, 2012, the U.S. District Court for the Western District of Texas unsealed a qui tam complaint that had been filed on November 19, 2010 by Desalle Bui, a former sales employee of the Company, which is the basis for the U.S. Attorney's investigation, to which the federal government, after three extensions of time, has elected to intervene. The complaint contains allegations of off-label promotion of Vari-Lase products for the treatment of perforator veins, re-use of single-use Vari-Lase products and Company-provided kickbacks to physicians, resulting in alleged damages to the government of approximately $20 million. The Company believes the allegations are factually inaccurate and without merit, and therefore the Company intends to both fully comply with the U.S. Attorney's investigation and defend the litigation. From time to time, the Company is involved in additional legal proceedings arising in the normal course of business. As of the date of this report the Company is not a party to any legal proceeding not described in this section in which an adverse outcome would reasonably be expected to have a material adverse effect on the Company's results of operations or financial condition. King Agreements On January 9, 2007, the Company entered into three separate agreements with King: a License Agreement, a Device Supply Agreement and a Thrombin-JMI Supply Agreement (See Note 8). King was acquired by Pfizer, Inc. on February 28, 2011. Under the License Agreement, the Company licensed the exclusive rights to the Company's products Thrombi-Pad®, Thrombi-Gel® and Thrombi-Paste® to King in exchange for a one-time license fee of $6,000,000. Under the Device Supply Agreement, the Company agreed to manufacture the licensed products for sale to King in exchange for two separate $1,000,000 milestone payments; one upon the first commercial sale of Thrombi-Gel (which was received on May 31, 2007), and one upon the first commercial sale of Thrombi-Paste (which has not been received and is not expected to be received). The Company was amortizing the $6,000,000 license fee on a straight-line basis over 10 years. The Company was amortizing the $1,000,000 milestone payment that was received on May 31, 2007 over the remaining 10-year license period. Under the Device Supply Agreement the Company agreed to pursue on behalf of King a surgical indication for the use of the Thrombi-Gel and Thrombi-Paste products from the FDA. The Device Supply Agreement requires the Company to make a one-time payment of $2,500,000 to King if the FDA does not approve the surgical indication of Thrombi-Gel and a one-time payment of $2,500,000 to King if the FDA does not approve the surgical indication of Thrombi-Paste after performing a clinical study and submitting the application. In 2009, King suspended further development of the Thrombi-Paste products. In 2010, King suspended further work on the pursuit of a surgical indication for the Thrombi-Gel products. On July 6, 2011, King notified the Company that King was terminating the development of the Thrombi-Paste products and terminating efforts to obtain the surgical indication for the Thrombi-Gel products. As a result of King making the decision to not proceed, the Company is not required to make either of the $2,500,000 payments to King, and instead the Company recognized revenue of $2,762,000 in the third quarter of 2011 as the remaining deferred license revenue originally allocated to the Thrombi-Paste products and the surgical indication of the Thrombi-Gel products as part of the King agreements. Amortization of the deferred revenue is $51,000 per quarter for the remainder of the 10-year license period, reflecting the remaining amortization allocated to the topical use indication of the Thrombi-Gel and Thrombi-Pad® products. The unamortized license fee was $866,000 and $1,019,000 at September 30, 2012 and December 31, 2011, respectively. The amortization of license fee was $153,000 and $3,171,000 for the nine months ended September 30, 2012 and 2011, respectively. Nicolai GmbH Agreement Effective April 1, 2008 the Company entered into a five-year distribution agreement with Nicolai GmbH. As a result of entering into this distribution agreement, the Company no longer maintains a direct sales force in Germany. In connection with this distribution agreement, the Company received 500,000 Euros from Nicolai GmbH, which was deferred and is being recognized ratably over the five-year term of the distribution agreement. The agreement also includes provisions requiring the Company to pay Nicolai GmbH specific amounts if the Company terminates the distribution agreement prior to the end of the five-year term. The Company does not intend to terminate the distribution agreement and, as such, has not recorded a liability relating to these potential future payments to Nicolai GmbH. The unamortized license fee was $73,000 and $182,000 at September 30, 2012 and December 31, 2011, respectively. The amortization of license fee was $109,000 and $108,000 for the nine months ended September 30, 2012 and 2011, respectively. Radius Medical Technologies, Inc. Contingent Consideration On October 20, 2010, the Company acquired the assets related to the snare and retrieval product line business from Radius Medical Technologies, Inc. and Radius Medical, LLC (collectively, "Radius"). Under the terms of the agreement the Company paid Radius a total of $6,449,000, consisting of $5,000,000 paid in cash at October 20, 2010 and $1,449,000 which was paid on June 9, 2011 upon the successful completion of the transfer of the manufacturing processes from Radius to the Company along with all fixed assets and inventory. In addition, Radius is entitled to receive an annual cash contingent consideration payment based on 25% of the net sales of the acquired products which exceed $2.0 million, $2.5 million, and $3.0 million for the calendar years ending December 31, 2011, 2012 and 2013, respectively. The range of possible contingent consideration payments is from $-0- if no sales are made in excess of the thresholds, to an undeterminable amount as the agreement does not contain a cap on the payment amounts. In accordance with ASC 805, a reduction of $96,000 and $586,000 in the liability amount was recorded at March 31, 2012 and September 30, 2011, respectively, and recognized as a gain in operating expenses within the general and administrative expenses. At September 30, 2012 and December 31, 2011, the Company has recorded a liability for these contingent consideration payments in the amount of $214,000 and $310,000, respectively.
