The following constitutes Amendment No. 2 to the Schedule 13D filed by the undersigned (“Amendment No. 2”). This Amendment No. 2 amends the Schedule 13D as specifically set forth herein.

Item 4.

Purpose of Transaction.

Item 4 is hereby amended to add the following:

On November 13, 2014, Broadfin Capital and its affiliates (“Broadfin”) issued an open letter to the Issuer’s shareholders. In the letter, Broadfin highlighted the undisputed facts of the Issuer’s continual underperformance under the leadership of the Board of Directors of the Issuer (the “Board”) and set the record straight with regard to the Issuer’s unfounded recent claims. The letter detailed that (i) the Shares have lost approximately 91% of their value since the Issuer’s IPO in 2006, (ii) the Issuer has produced negative returns for the past 1-, 3-, and 5 - year periods and since its IPO, (iii) the Issuer has, since it became a public company, underperformed the NASDAQ Composite Total Returns Index by 210.5%, Russell 200 Total Return Index by 171.3% and the S&P Healthcare Total Return Index by 227.9% and (iv) the Issuer has missed revenue expectations 78% of the time and has failed to achieve its own set of pipeline milestones within deadline in 59% of the cases. Broadfin also set the record straight regarding a number of unfounded claims made by the Issuer in its recent filings with the SEC.

Broadfin noted its three independent nominees, Gregory D. Casciaro, R. Michael Kleine and Samuel E. Navarro, bring a combination of valuable and much needed experience on the Board, including directly relevant experience and knowledge of new product launches in the surgical markets, both domestically and in key international markets, financial expertise, strong track records of prior success and commitment to shareholder value. Broadfin concluded by urging all stockholders to vote on its GOLD proxy card to elect Broadfin’s three nominees to the Board at the upcoming 2014 Annual Meeting. The full text of the letter is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

Item 7.

Material to be Filed as Exhibits.

Item 7 is hereby amended to add the following exhibit:

99.1

Open Letter to Shareholders, dated November 13, 2014.
