ITEM 8.01. OTHER EVENTS.

In connection with the litigations we initiated in 2004 in the U.S. District
Court for the District of Massachusetts against AngioDynamics, Inc., Vascular
Solutions, Inc. and Total Vein Solutions LLC and New Star Lasers, Inc. for
infringement of our U.S. Patent No. 6,398,777 (the "'777 Patent"), in December
2005, we moved for summary judgment that the '777 Patent is valid, enforceable
and infringed by AngioDynamics and Vascular Solutions, and AngioDynamics and
Vascular Solutions moved for summary judgment of non-infringement. A hearing of
the parties' respective motions was scheduled for June 1, 2006. That hearing has
now been postponed by the court.

The postponement results from an order of the court dated May 22, 2006 wherein
the judge, Richard G. Stearns, who is hearing the case, indicates that he
recently became a patient of Dr. Cheih-Min Fan at Massachusetts General
Hospital. The Company had previously engaged Dr. Fan as an expert witness in the
'777 Patent litigation. In his order, Judge Stearns has asked that the Company
provide the court and the other parties with a description of Dr. Fan's expected
role in the '777 Patent litigation within 14 days, and that the Company and the
other parties indicate to the court within 28 days whether the doctor-patient
relationship at issue and the circumstances of Judge Stearns' proposed treatment
using the Company's products creates a ground for recusal or disqualification,
and if so, whether the parties are willing to waive any potential conflict. The
hearing scheduled for June 1, 2006 has accordingly been postponed by the court
to permit the parties an opportunity to respond.

A complete copy of Judge Stearn's order is attached hereto as Exhibit 99.1.
