(a) The Company hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) to reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment hereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement; (iii) to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement; provided, however, that the undertakings set forth in paragraphs (i) and (ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the SEC by the Company pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered hereby which remain unsold at the termination of the offering. (b) The Company hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (h) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director or officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being II-3

registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Delcath Systems, Inc.
1100 Summer Street
Stamford, Connecticut 06905

                  Re:      Registration Statement on Form S-8

Dear Sirs:

     We have acted as special counsel to Delcath Systems, Inc., a Delaware
corporation (the "Company"), in connection with its Registration Statement on
Form S-8 being filed on the date hereof (the "Registration Statement"), for the
offering by it of up to 4,251,542 shares (the "Shares") of its Common Stock, par
value $0.01 (the "Common Stock") issuable upon exercise of awards that have been
granted pursuant to its 2000 Stock Option Plan or its 2001 Stock Option Plan or
that may be granted pursuant its 2004 Stock Incentive Plan (individually, a
"Plan" and, collectively, the "Plans").

     We have examined and relied upon originals or copies, certified or
otherwise identified to our satisfaction of the following documents: (a) the
Amended and Restated Certificate of Incorporation of the Company, as amended, in
the form filed as Exhibit 3.1 to the Company's Quarterly Report on Form 10-QSB
for the quarter ended June 30, 2004 (file No. 001-16133); (b) the Amended and
Restated Bylaws of the Company in the form filed as Exhibit 3.2 to Amendment No.
1 to the Company's Registration Statement on Form SB-2 (No. 333-39470); (c) a
Certificate dated the date hereof of the Company's President and Chief Executive
Officer as to certain matter of fact; (d) the Plans; and (e) such other
documents as we have considered necessary to the rendering of the opinions
expressed below.

     In our examination of the foregoing, we have assumed that: (a) the
statements made therein are accurate and complete; (b) the signatures on
documents and instruments submitted to us as originals are authentic; and (c)
documents submitted to us as certified, conformed or photostatic copies of
original documents conform with the originals thereof and the originals thereof
are authentic. We have also assumed that each award granted or that may be
granted under the Plans was or will be granted in accordance with the respective
Plan under which it was or will be granted.



The Board of Directors Delcath Systems, Inc. October 21, 2004 Page 2 In rendering the opinion set forth below, we have also assumed that, upon issuance of the Shares upon exercise of awards under the Plans, the total number of shares of Common Stock issued and outstanding will not exceed the total number of shares of Common Stock that the Company is then authorized to issue. Based upon the foregoing and assuming that the purchase price of the Shares issued pursuant to the Plans will be not less than the par value of the Shares, we are of the opinion that the Shares will, upon issuance in accordance with the provisions of the respective Plan subsequent to the exercise of awards granted under such Plan, be legally issued, fully paid and nonassessable. The foregoing opinion is limited to the General Corporation Law of the State of Delaware, and we do not express any opinion herein concerning any other law. We assume no obligation to supplement this opinion if any applicable law changes after the date hereof or if we become aware of any fact that might change the opinion expressed herein after the date hereof. This opinion is being furnished to you for filing as an exhibit to the Registration Statement and, accordingly, may not be relied upon by or quoted in any manner or delivered to any other person or entity without, in each instance, our prior written consent. We consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm appearing under the caption "Legality" in the Prospectuses forming part of the Registration Statement. In giving this consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder. Very truly yours, MURTHA CULLINA LLP By /s/ PAUL G. HUGHES -------------------------- Paul G. Hughes



                                                                    EXHIBIT 23.1




            CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


We consent to the incorporation by reference in the Registration Statement on
Form S-8 of our report dated February 11, 2004 (March 22, 2004 with respect to
Note 6) on our audits of the financial statements of Delcath Systems, Inc. (the
"Company") as of December 31, 2003 and for each of the years in the two-year
period ended December 31, 2003 and for the period from August 5, 1988
(inception) to December 31, 2003.
