Trimedyne Reports Its Financial Results for the Quarter and Nine Months Ended June 30, 2009

LAKE FOREST, CA--(Marketwire - August 17, 2009) - TRIMEDYNE, INC. (OTCBB: TMED) today
reported its financial results for the quarter and nine month period ended
June 30, 2009.

Revenues for the current quarter were $2,068,000, an increase of 49% over
revenues of $1,385,000 for the prior year's quarter. The $683,000 increase
in revenues was due to higher revenues from sales of fiber optic devices,
lasers, field service and rentals. The gross profit margin in the current
quarter was 40% of revenues, compared to 27% for the prior year quarter.
The Company had a net loss of $82,000 or $0.00 per share for the current
quarter, an 86% reduction from the loss of $585,000 or $0.03 per share for
the prior year quarter.

For the nine months ending June 30, 2009, revenues were $5,310,000, a 30%
increase over revenues of $4,090,000 in the prior year period, and the
Company's net loss for this period was $872,000 or $0.05 per Share, a 30%
reduction from the net loss of $1,254,000 or $0.07 per Share for the prior
year period.

Commenting on the financial results for the quarter, Marvin P. Loeb, Sc.D.,
Chairman of Trimedyne, said, "We are pleased with the 49% increase in
revenues in the current quarter over the year ago quarter, which is also
27% higher than the revenues of $1,632,000 for the quarter ended March 31,
2009, and our loss in the current quarter was a 76% reduction from the loss
of $345,000 for the quarter ended March 31, 2009."

Trimedyne has developed a new side firing optical fiber for use with 80 and
100 watt Holmium Lasers for the treatment of benign prostate hyperplasia or
BPH, commonly called an enlarged prostate. We are beginning a limited
marketing release of the new fiber under our VaporMAX® trademark at a
price significantly lower than the prices of side firing fibers marketed by
certain of our competitors. Our VaporMAX® Fiber is designed to operate
at 80 or 100 watts of Holmium Laser energy for one hour or longer. Our
competitors' side firing fibers sometimes fail before a BPH patient's
treatment has been completed, interrupting the procedure and requiring the
hospital to use a second fiber.

BPH is a condition which affects an estimated 50% of men over age 55 and an
increasing percentage of men at older ages. Worldwide, an estimated 1.2
million men are presently treated each year in a surgical procedure
primarily using radiofrequency (RF) or laser energy to remove excess
prostate tissue which is obstructing urine flow. The laser procedure is
usually performed on an outpatient basis and reduces the adverse effects of
the RF surgical procedure, which typically requires a hospital stay and can
entail significant bleeding, impotence and incontinence.

Trimedyne has developed a similar side firing optical fiber which will be
marketed throughout the world by Lumenis, Ltd. of Yokneam, Israel, under
Lumenis' DuraMAX trademark. Lumenis markets its side firing fibers through
Boston Scientific Corporation in the U.S. and Japan. Elsewhere throughout
the world, Lumenis markets its side firing fibers through its established
sales organization. The DuraMAXT side firing fiber will be used with
Lumenis' large, worldwide installed base of 80 and 100 watt Holmium Lasers
for the treatment of BPH.

Marketing of the new DuraMAXT Fiber by Lumenis will commence when an
audit of our manufacturing process and quality system is completed, which
is expected to take several months to complete. We have not been advised
when the audit will be commenced.

Trimedyne manufactures patented fiber optic laser devices and proprietary
Holmium Lasers for the treatment of BPH, as well as for the treatment of
herniated or ruptured discs in the spine and a variety of other, minimally
invasive surgical procedures, many of which are performed on an outpatient
basis at substantially less cost than conventional surgery. For product,
