ITEM 8.01. OTHER EVENTS.

On January 3, 2006, through a press release issued by AngioDynamics Inc.
("AngioDynamics"), a subsidiary of E-Z-EM, Inc., Diomed Holdings, Inc. (the
"Company"), learned that a lawsuit had been filed against the Company in the
U.S. Federal District Court for the District of Delaware by AngioDynamics,
seeking a declaratory judgment that the claims of U.S. Patent Number 6,981,971
(the "971 Patent") are invalid, unenforceable and not infringed by
AngioDynamics. The 971 Patent relates to a particular 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.

The Company believes AngioDynamics' declaratory judgment action regarding the
971 Patent to be without merit, and intends to address and respond appropriately
to the allegations contained in AngioDynamics' complaint in this action.

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 the
AngioDynamics' 971 Patent suit are unrelated to the 777 Patent litigation, which
is currently pending.
