Item 3.01.  Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On October 29, 2008, PLC Systems Inc. (the “ Company ”) received a notice from NYSE Alternext US LLC (“ NYSE Alternext ”), which was formerly known as the American Stock Exchange LLC (“ AMEX ”), indicating that NYSE Alternext intends to delist the Company’s common stock.

As previously reported, on September 17, 2008, the Company received a notice from AMEX stating that the Company was not in compliance with the continued listing standards set forth in Section 1003(a)(ii) of the AMEX Company Guide as a result of the Company’s stockholders’ equity being less than $4,000,000 and the Company having had losses from continuing operations and net losses in three of its four most recent fiscal years.  The Company had until October 17, 2008 to submit a plan to bring the Company back into compliance with the continued listing standards by March 17, 2010.  The Company did not submit such a plan of compliance.

If the Company does not appeal NYSE Alternext’s determination to delist the Company’s common stock by November 5, 2008, then NYSE Alternext’s determination will become final and the Company’s common stock will be delisted from NYSE Alternext.  The Company does not expect to file such an appeal.

A copy of the press release announcing the notification from NYSE Alternext is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
