Surgical device maker Misonix Inc., whose internal investigation has found issues involving financial reporting and possible violations of the Foreign Corrupt Practices Act, Thursday announced that it would be unable to file its latest quarterly report within the extension period provided under federal securities law.

The Farmingdale maker of ultrasonic products used in surgery and wound debridement said that it had alerted the Securities and Exchange Commission that it would be unable to file a timely report for the quarter ended Sept. 30.

The company also has yet to file its annual report for the fiscal year ended June 30, and a Misonix spokesman said no date has been set for delivering that document.

The spokesman said the annual report would precede the filing of the quarterly report.

In a September filing, the company said it may have been aware of practices by a distributor in China that violate laws barring Americans from bribing foreign government officials and requiring companies to maintain accounting systems that would reveal bribery.

Shares of Misonix rose 2.4 percent to close at $8.40 in Thursday trading on the Nasdaq Stock Market. Year to date, the shares have declined 10.6 percent.
