ITEM 8.01. OTHER EVENTS.

As disclosed in a Current Report on Form 8-K filed on January 6, 2006 with the
Securities and Exchange Commission by Diomed Holdings, Inc. (the "Company"), on
January 3, 2006, AngioDynamics Inc. ("AngioDynamics") filed a lawsuit against
the Company in the U.S. District Court for the District of Delaware, seeking a
declaratory judgment that the claims of Diomed, Inc.'s U.S. Patent Number
6,981,971 (the "971 Patent") are invalid, unenforceable and not infringed by
AngioDynamics. The 971 Patent relates to an introducer sheath/optical fiber
arrangement that may be used in the endovascular laser treatment of varicose
veins. The 971 Patent was issued by the U.S. Patent and Trademark Office on
January 3, 2006, the day AngioDynamics filed the lawsuit.

On January 17, 2006, AngioDynamics filed an Amended Complaint seeking a
declaratory judgment with respect to Diomed, Inc.'s U.S. Patent Number 6,986,766
(the "766 Patent") as well. The 766 Patent relates to methods of using an
introducer sheath/optical fiber arrangement in the endovascular laser treatment
of varicose veins.

On January 31, 2006, the Company filed a motion to dismiss AngioDynamics'
declaratory judgment action in its entirety. The Company's motion to dismiss is
based primarily on lack of declaratory judgment jurisdiction. The Company also
asserts in its motion to dismiss that the court should dismiss the action in its
discretion, and because AngioDynamics' complaint contains a number of
deficiencies which warrant dismissal.

As noted in the Company's Current Report of January 6, 2006, in a separate
action that the Company commenced in January 2004, the Company sued
AngioDynamics in the U.S. Federal District Court for the District of
Massachusetts, seeking injunctive relief and damages for infringement of
Diomed's U.S. Patent No. 6,398,777 (the "777 Patent"). The issues raised in
AngioDynamics' Delaware declaratory judgment suit are unrelated to the 777
Patent litigation, which is currently still pending.
