             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Administrative Committee
Arrow International, Inc. 401(k) Plan
Reading, Pennsylvania

      We have audited the accompanying statements of net assets available for
benefits of the Arrow International, Inc. 401(k) Plan as of December 31, 2003
and August 31, 2003, and the related statements of changes in net assets
available for benefits for the four-month period ended December 31, 2003 and the
year ended August 31, 2003. These financial statements are the responsibility of
the Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

      We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

      In our opinion, the financial statements referred to above present fairly,
in all material respects, the net assets available for benefits of the Arrow
International, Inc. 401(k) Plan as of December 31, 2003 and August 31, 2003, and
the changes in net assets available for benefits for the four-month period ended
December 31, 2003 and the year ended August 31, 2003 in conformity with
accounting principles generally accepted in the United States of America.

      Our audits were conducted for the purpose of forming an opinion on the
basic financial statements taken as a whole. The supplementary schedule of
assets (held at end of year) as of December 31, 2003 is presented for the
purpose of additional analysis and is not a required part of the basic financial
statements, but is supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. The supplementary schedule is the
responsibility of the Plan's management. The supplementary schedule has been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, is fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

ARROW INTERNATIONAL, INC. 401(K) PLAN
- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS

NOTE 1 - DESCRIPTION OF PLAN

            The following brief description of the Arrow International, Inc.
      401(k) Plan (the Plan) is provided for general purposes only. Participants
      should refer to the Plan agreement for a more complete description of the
      Plan's provisions.

            General

                  The Plan is a contributory, defined contribution plan which
                  was adopted on September 1, 1991 to establish a deferred
                  compensation arrangement under the provisions of Section
                  401(a) of the Internal Revenue Code (the Code). The Plan is
                  subject to the provisions of the Employee Retirement Income
                  Security Act of 1974 (ERISA) and is intended to be a qualified
                  plan under Section 401(a) of the Code. Effective September 1,
                  2003, the Plan year-end was changed to December 31 from August
                  31.

            Eligibility

                  All employees of Arrow International, Inc. (the Company) and
                  any of its affiliates which adopt the Plan are eligible to
                  participate in the Plan immediately upon hire except (i)
                  non-resident aliens and (ii) employees who are not scheduled
                  to work 1,000 hours or more annually; provided, however, any
                  employee who does work or is credited with at least 1,000
                  hours of service during a plan year will be eligible to
                  participate.

            Participant Accounts

                  Each participant's account is credited with the participant's
                  contributions and credited or charged with allocations of (a)
                  the Company's contributions and (b) Plan investment earnings
                  and losses, and administrative expenses, if any.

            Forfeited Accounts

                  As of December 31, 2003 and August 31, 2003, forfeited
                  employer matching non-vested accounts amounted to $16,565 and
                  $11,232, respectively. Forfeitures of employer matching
                  non-vested accounts are used to reduce the employer's matching
                  401(k) contribution. During the periods ended December 31,
                  2003 and August 31, 2003, forfeitures of $-0- and $125,563,
                  respectively, were applied against employer contributions.

            Vesting

                  Participants are immediately vested in their voluntary
                  contributions plus actual earnings thereon. A participant
                  becomes 20% vested in the Company's discretionary
                  contributions to the Plan after one year of service. Vesting
                  increases 20% each year until the participant is fully vested
                  after five years of credited service.

NOTE 1 - DESCRIPTION OF PLAN (CONTINUED)

            Contributions

                  Employee Tax Deferred Contributions

                        Eligible participants may contribute up to 20% of their
                        pre-tax earnings. Participants are not permitted to
                        allocate more than 50% of their contribution to the
                        Arrow International Common Stock Fund.

                  Employer Contributions

                        The Plan sponsor can make discretionary matching
                        contributions to the Plan. During the four-month period
                        ended December 31, 2003 and the year ended August 31,
                        2003, the Company made this discretionary matching
                        contribution at the rate of 50% of every dollar
                        contributed by employees up to a maximum of 2% of the
                        employee's pre-tax salary.

                  Other Employer Contributions

                        The Plan sponsor is permitted to make a discretionary
                        contribution to the Plan for the benefit of all
                        employees. This contribution is to be made in the form
                        of the Company's common stock. During the four-month
                        period ended December 31, 2003 and the year ended August
                        31, 2003, the Plan sponsor chose to make this
                        contribution at the rate of 1% of each employee's
                        monthly salary. Once this contribution is made,
                        participants have the ability to liquidate the stock and
                        move the proceeds into other Plan investment options.
                        Participants are immediately 100% vested in this
                        contribution.

            Participant Loans

                  A participant may borrow from their accounts a minimum of
                  $1,000 up to a maximum of the lesser of $50,000 or 50% of
                  their vested account balance. Loan terms may not exceed five
                  years unless the loan is for the purchase of a primary
                  residence. Loans are secured by the balance in the
                  participant's account and bear interest at the prime rate.
                  Loans are repaid through regular payroll deductions.

            Administrative Costs

                  Substantially all plan expenses are paid by the Plan sponsor.

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

            Estimates

                  The preparation of financial statements in conformity with
                  accounting principles generally accepted in the United States
                  of America requires management to make estimates and
                  assumptions that affect the reported amounts of assets and
                  liabilities and disclosure of contingent assets and
                  liabilities at the date of the financial statements and the
                  reported amounts of revenues and expenses during the reporting
                  period. Actual results could differ from those estimates.

                  are stated at their unpaid principal balance which
                  approximates their fair value. The change in the difference
                  between fair value and the cost of investments is reflected in
                  the statements of changes in net assets available for benefits
                  as a component of the net realized and unrealized appreciation
                  (depreciation) in fair value of investments.

                  Investments of the Plan are exposed to various risks, such as
                  interest rate, market and credit. Due to the level of risk
                  associated with certain investments and the level of
                  uncertainty related to changes in the value of investments, it
                  is at least reasonably possible that changes in risks in the
                  near term would materially affect investment assets reported
                  in the statements of net assets available for benefits and the
                  statements of changes in net assets available for benefits.

                  Purchases and sales of securities are recorded on a trade date
                  basis. Interest income is recorded on the accrual basis.
                  Dividends are recorded on the ex-dividend date.

            Payment of Benefits

                  Benefit payments to participants are recorded when paid.

                  There were distributions due participants in the amount of $37
                  and $24,679 at December 31, 2003 and August 31, 2003,
                  respectively.

      Plan termination, participants would become 100% vested in their employer

NOTES TO FINANCIAL STATEMENTS

NOTE 5 - INCOME TAX STATUS

            The Plan obtained its latest determination letter on December 18,
      2002, in which the Internal Revenue Service stated that the Plan, as then
      designed, was in compliance with the applicable requirements of the Code.
      The Plan has been amended since receiving the determination letter.
      However, the Plan administrator and the Plan's tax counsel believe that
      the Plan is currently designed and being operated in compliance with the
      applicable requirements of the Code. Therefore, no provision for income
      taxes has been included in the Plan's financial statements.

NOTE 6 - PARTIES-IN-INTEREST TRANSACTIONS

            Certain Plan investments are mutual funds that are managed by T.
      Rowe Price, the Plan's trustee and a party-in-interest to the Plan. The
      Plan also has a common stock fund which holds shares of Arrow
      International, Inc., the Plan sponsor and a party-in-interest. The Plan
      held 243,596 shares and 230,777 shares of Arrow International, Inc. common
      stock at December 31, 2003 and August 31, 2003, respectively.

            Fees paid during the periods ended December 31, 2003 and August 31,
      2003 for administrative services rendered by parties-in-interest were
      based on customary and reasonable rates for such services.

NOTE 7 - EXCESS CONTRIBUTIONS

            As of December 31, 2003 and August 31, 2003, net assets available
      for benefits include approximately $45,000, due to certain active
      participants for excess deferral contributions. Excess contributions
      associated with the Plan year ended August 31, 2002, in the amount of
      $68,000 were recorded as a reduction in contributions for the Plan year
      ended August 31, 2003. The excess contributions as of December 31, 2003
      will be recorded as benefit payments when distributed in 2004.
