                 ARROW INTERNATIONAL, INC. REPORTS THIRD QUARTER
                    AND NINE MONTHS FISCAL YEAR 2004 RESULTS

READING, PA, June 23, 2004 - Arrow International, Inc. announced today that net
sales for its third quarter of fiscal 2004 ended May 31, 2004 increased 12.3% to
$108.8 million compared to $96.9 million in the same prior year period. Net
income for the quarter reflects charges related to the Arrow LionHeart(TM) Left
Ventricular Assist System program, as described below, and, as a result of these
charges, decreased 20.0% to $11.6 million compared to $14.5 million in the same
prior year period. Diluted earnings per share for the quarter decreased 21.2% to
$0.26 per share compared to $0.33 per share in the same fiscal 2003 period.

For the nine months ended May 31, 2004, compared to the same period of last
year, the Company's net sales increased 15.0% to $320.2 million from $278.5
million. Net income was $41.5 million during the period compared to $37.8
million in the comparable period of fiscal 2003, an increase of 9.8%. Diluted
earnings per share were $0.94 per share compared to $0.86 per share in the same
prior year period, an increase of 9.3%.

As a result of the Company's previously announced decision on April 15, 2004 to
delay commencement of the Arrow LionHeart(TM) Phase II U.S. clinical trials, the
Company incurred charges totaling $3.7 million, or $0.06 diluted earnings per
share, in the third fiscal quarter. The charges consist primarily of an
inventory write-off of $3.1 million, or $0.05 diluted earnings per share, for
certain LionHeart(TM) components that became obsolete with the Company's
decision not to proceed with the clinical trials using the first generation
LionHeart(TM) power system and controller. The other charge was for equipment
write-off of $0.6 million, or $0.01 per diluted earnings per share. In addition,
in the third quarter of fiscal year 2004, the Company incurred research,
development and engineering expense of $1.1 million, or $0.01 diluted earnings
per share, for completion of the second generation LionHeart(TM) power system
and controller. The Company's remaining investment in the LionHeart(TM) includes
$2.0 million of components usable with either the first or second generation
electronics and $2.5 million in manufacturing equipment.

Results of Total Company Operations,
excluding, as described above, the charges
for LionHeart(TM)  inventory and equipment
write-offs, and research, development and
engineering expense incurred in the third
quarter of fiscal year 2004 for second
generation components

        *Includes Diatek(TM) and NEOCARE(R) product sales in the third fiscal
        quarters of both years.

Carl G. Anderson, Jr., Arrow International's Chairman and Chief Executive
Officer, stated "We continue to be encouraged by the Company's core growth rate,
which is running at 9.8% on a fiscal year-to-date basis, adjusted for the
acquisitions of Diatek(TM) and NEOCARE(R) in fiscal year 2003, and for favorable
exchange rates. Importantly, our growth has been reasonably broad-based, with
progress in central venous catheters, specialty catheters and cardiac care
products. On a geographic basis, we continue to see encouraging growth in both
domestic and international markets, which we believe is attributable in part to
our strengthened marketing and sales effort."

"The introduction of the AutoCAT(R) 2 WAVE(TM) intra-aortic balloon pump is
generating a positive response with customers. Physicians have reported positive
patient outcomes with this breakthrough technology. However, the selling process
in the third quarter has been slowed somewhat by ramp-up issues in
manufacturing. While we do not believe this will impact the long-term growth of
the AutoCAT(R) 2 WAVE(TM), some lingering impact may be felt in the fourth
quarter of fiscal year 2004."

"The Company's strong growth over the past few years has absorbed most of its
manufacturing capacity. To support projections for future growth and integrate
operations acquired in recent years, the Company expects to initiate a
multi-year capital investment plan to increase manufacturing capacity and
rationalize its production operations. The first phase of this effort will
include an additional manufacturing site in the Czech Republic and expansion of
the plant in Chihuahua, Mexico. We expect to provide an estimate of the cost of
this construction in the Company's September 29, 2004 release of fourth quarter
and fiscal year 2004 financial results."

Assumptions:
        1)      Targets for fourth quarter and full fiscal year 2004 exclude
                research, development and engineering expenses for second
                generation LionHeart(TM) components in both the third and fourth
                quarters of fiscal year 2004 and the write-offs of certain
                LionHeart(TM) obsolete components and manufacturing equipment in
                the third quarter of fiscal year 2004.
        2)      Fourth quarter and fiscal year 2003 results exclude the
                previously reported special charge, charge to research,
                development and engineering expense, and interest income
                relating to amended federal tax returns.
        3)      Gross margin of 51.9% of sales for the fourth quarter and 52.3%
                for the full 2004 fiscal year.

                quarter and 31.4% to 31.7% for the full 2004 fiscal year.
        5)      Operating income of 20.2% to 21.4% of sales for the fourth
                quarter and 20.6% to 20.9% for the full 2004 fiscal year.
        6)      Effective tax rate of 32.5%.
        7)      E.P.S. using 44,500,000 shares of common stock outstanding.
        8)      R&D expenses of approximately 6.3% to 6.5% of sales for the
                fourth quarter and 6.4% for the full 2004 fiscal year, excluding
                research, development and engineering expenses for the second
                generation LionHeart(TM) expenses in the third quarter of fiscal
                year 2004 of $1.1 million and an estimate for the fourth quarter
                of fiscal year 2004 of $1.4 million.
        9)      A = Actual; E = Estimate; M = Millions

Note:   Third quarter fiscal year 2004 targets were as follows:

Net Sales              $106-108M

Diluted E.P.S.         $0.33-.35

Arrow expects to submit dossiers for the second generation LionHeart(TM) power
system and controller to the Company's European Notified Body, TUV Product
Services of Munich, Germany, in the fall of 2004 and anticipates receiving an
approval for use of these electronics in the device approximately three months
later, given that many of its components have not changed, no additional
clinical data is required and the LionHeart(TM) quality system has already been
certified. Arrow's European marketing plan for the LionHeart(TM) is based upon
the receipt of this approval and the CE-marking of the second generation
electronics.

The Company has made significant progress in its efforts to develop and test
modifications to its CorAide(TM) continuous flow ventricular assist device to
resolve elevated levels of hemolysis experienced in the first implant of the
device. The Company expects that European clinical trials of the CorAide(TM)
device should resume later this calendar year although, due to the pioneering
nature of this program, it is difficult to predict precise timing.

In March 1999, the Company began open market purchases of its common stock
pursuant to its previously announced program to repurchase up to 2 million
shares of its common stock. In April 2000, the Company announced that it would
repurchase up to another 2 million shares of its stock under this program, for a
total of 4 million. As of May 31, 2004, the Company had purchased a total of
3,603,600 shares under this program, which remains in effect.

"Safe Harbor" Statement under the Private Securities Litigation Reform Act of
1995: This news release provides historical information and includes
forward-looking statements (including projections). Although the Company
believes that the expectations in such forward-looking statements are
reasonable, the Company can give no assurance that such expectations will prove
to have been correct. The forward-looking statements are based upon a number of
assumptions and estimates that, while presented with numerical specificity and
considered reasonable by the Company, are inherently subject to significant
business, economic and competitive risks, uncertainties and contingencies which
are beyond the control of the Company, and upon assumptions with respect to
future business decisions which are subject to change. Accordingly, the
forward-looking statements are only an estimate, and actual results will vary
from the forward-looking statements, and these variations may be material.
Consequently, the inclusion of the forward-looking statements should not be
regarded as a representation by the Company of results that actually will be
achieved. Forward-looking statements are necessarily speculative in nature, and
it is usually the case that one or more of the assumptions in the
forward-looking statements do not materialize. Investors are cautioned not to
place undue reliance on the forward-looking statements. In connection with the
"Safe Harbor" provisions of the Private Securities Litigation Reform Act of
1995, the Company cautions the reader that the factors below, which are
discussed, in the Company's Annual Report on Form 10-K for the fiscal year ended
August 31, 2003 and in its other filings with the Securities and Exchange
Commission, could cause the Company's results to differ materially from those
stated in the forward-looking statements. These factors include: (i) stringent
regulation of the Company's products by the U.S. Food and Drug Administration
and, in some jurisdictions, by state, local and foreign governmental
authorities; (ii) the highly competitive market for medical devices and the
rapid pace of product development and technological change in this market; (iii)
pressures imposed by the health care industry to reduce the cost or usage of
medical products and services; (iv) dependence on patents and proprietary rights
to protect the Company's trade secrets and technology, and the need for
litigation to enforce or defend these rights; (v) risks associated with the
Company's international operations; (vi) potential product liability risks
inherent in the design, manufacture and marketing of medical devices; (vii)
risks associated with the Company's use of derivative financial instruments; and
(viii) dependence on the continued service of key members of the Company's
management.
