                     DIOMED ANNOUNCES THIRD QUARTER RESULTS

                 Company Delivers 22% Increase in EVLT(R) Sales

ANDOVER, MA, October 26, 2006 --- Diomed Holdings, Inc. (AMEX: DIO), a leading
developer and marketer of minimally invasive medical technologies, including its
patented EVLT(R) laser treatment for varicose veins, today announced results for
the third quarter ended September 30, 2006.

Significant accomplishments during the third quarter of 2006 included:

      o     Diomed's third highest quarterly revenue performance, at $5.3
            million;
      o     EVLT(R) revenue, 22% above the third quarter of 2005;
      o     EVLT(R) disposable revenue, 44% over the third quarter of 2005;
      o     EVLT(R) installed base exceeds 1,000 laser systems;
      o     Nearly 80,000 EVLT(R) procedures successfully performed;
      o     Close of $10 million preferred stock financing, increasing cash and
            short term investments to $13.4 million.
      o     Summary Judgment ruling that `777 patent is valid and enforceable,
            eliminating two of the three defenses and allowing trial on
            infringement action to proceed;

"We are pleased with our third quarter accomplishments," commented James A.
Wylie, CEO and President of Diomed Holdings, Inc. "The Company drove significant
year-over-year growth in what is traditionally our softest quarter due to
seasonality in our key North American EVLT(R) market. Additionally, Diomed
delivered revenue for the nine months ended September 30, 2006 of $16 million,
an increase of $2.5 million, or 18%, over the first nine months of 2005, while
EVLT(R) sales increased a solid 23%."

"Of particular note is our continued growth in laser market share. During the
three-month period ending August 2006, Diomed sold over three times the number
of lasers sold by our largest competitor, strengthening our belief that Diomed's
installed base exceeds the installed base of all of our laser competitors
combined." Wylie further commented.

Gross profit for the third quarter of 2006 was $2.3 million, representing an
increase of $208,000, or 10%, over the third quarter of 2005. Gross profit as a
percentage of sales of 43% decreased 2.4 percentage points against the third
quarter of 2005, as a less favorable product mix and lower overhead absorption
offset favorable pricing variances. The Company has targeted continued
improvement in gross profit levels to the 60% level and higher, consistent with
other proprietary medical device companies, as the EVLT(R) product line grows.

                                       4


Selling and marketing expenses for the third quarter of 2006 were $2.7 million,
an increase of $606,000, or 29%, over the third quarter of 2005. The increase
was driven by an expansion of our sales force, higher sales commissions
resulting from the increased sales volume and increased marketing expenditures
in support of our sales initiatives to drive the growing commercialization of
EVLT(R). For the nine months ended September 30, 2006, selling and marketing
expenses were $8.5 million, an increase of $1.8 million, or 27%, over the same
period of 2005.

General and administrative expenses for the third quarter of 2006 of $1.9
million increased $95,000, or 5%, compared to the third quarter of 2005, and
were relatively flat sequentially. Total third quarter legal costs of $694,000
decreased $16,000 from the second quarter of 2006, with a reduction in the
continuing cost of litigation against our primary laser competitors offset by
the cost of litigation in the action brought by our radio-frequency competitor.
For the nine months ended September 30, 2006, general and administrative
expenses were $5.9 million, an increase of $390,000, or 7%, over the same period
in 2005.

Losses from operations for the third quarter of 2006 of approximately $2.7
million increased $513,000 from the third quarter of 2005, as gains from
incremental revenue were offset by increased selling and marketing costs and
$126,000 in SFAS 123R compensation costs. Losses from operations for the nine
months ended September 30, 2006 were $8.3 million, compared with $7.2 million
for the same period in 2005, and included $444,000 in SFAS 123R stock based
compensation charges.

Net loss for the third quarter of 2006 of $3.0 million increased by $620,000, or
26%, from the third quarter of 2005. Net loss for the third quarter of 2006
includes a $69,000 non-cash, non-operating loss for the increase in the fair
value of the warrant obligation entered into on September 30, 2005, as the
market price of the Company's stock increased from $1.11 at June 30, 2006 to
$1.20 at September 30, 2006. As a result of the financing which closed on
September 29, 2006, the Company marked to market the warrant obligation for a
final time and reclassified its mezzanine level preferred stock and warrant
liability to permanent equity.

Upon completion of the 2006 preferred stock financing, the Company recorded a
one-time, non-cash, non-operating beneficial conversion feature charge of
$469,938, since the market price of the Company's common stock on September 29,
2006 of $1.20 was above the $1.15 effective conversion price of the immediately
convertible preferred stock. The Company also recorded a one-time, non-cash,
non-operating deemed dividend of $3.0 million on the exchange of the 2005
preferred stock for the 2006 preferred stock.

Net loss applicable to common stockholders for the third quarter of 2006 was
$6.7 million, or $0.35 per share, compared to $3.1 million, or $0.16 per share,
for the third quarter of 2005. Net loss applicable to common stockholders for
the third quarter of 2006 includes $167,000 of non-cash preferred stock
dividends accreted for future increasing rate dividends and $149,000 of
preferred stock cash dividends earned during the third quarter on the 2005
preferred stock. As noted above, the 2005 preferred stock was exchanged for the
2006 preferred stock under the 2006 financing, which does not accrue dividends
unless a future dilutive financing is completed within certain terms.

                                       5


The Company ended the third quarter of 2006 with a cash and short term
investment balance of $13.4 million, compared to a cash and short term
investment balance of $7.0 million at the end of the second quarter of 2006. The
cash balance includes approximately, $9.3 million in net proceeds received from
the 2006 preferred stock financing.
