120,000 SHARES

CARDIOVASCULAR DYNAMICS, INC.
COMMON STOCK


This Prospectus relates to the public offering, which is not being underwritten, of 120,000 shares of Common Stock, $.001 par value per share, of CardioVascular Dynamics, Inc. ("CVD", the "Company" or the "Registrant"). All 120,000 shares (the "Shares") may be offered by SCIMED Life Systems, Inc. ("SCIMED") or by pledgees, donees, transferees or other successors in interest that receive such shares as a gift, partnership distribution or other non-sale related transfer (together with SCIMED, the "Selling Stockholders"). All of the Shares were originally issued by the Company to SCIMED pursuant to the exercise of two warrants for 40,000 and 20,000 shares, respectively, issued to SCIMED in exchange for a waiver of SCIMED's anti-dilution rights under the Stock Purchase and Technology License Agreement dated September 10, 1994 by and between the Company and SCIMED (the "SCIMED Agreement"), which converted into the right to receive 80,000 and 40,000 shares, respectively, upon the consummation of the Company's initial public offering. The Shares were issued pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"), provided by Section 4(2) thereof. The Shares are being registered by the Company pursuant to Schedule 6.1 of the SCIMED Agreement.

The Shares may be offered by the Selling Stockholders from time to time in transactions in the over-the-counter market, in negotiated transactions, or a combination of such methods of sale, at fixed prices which may be changed, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. The Selling Stockholders may effect such transactions by selling the Shares to or through broker-dealers, and such broker-dealers may receive compensation in the form of discounts, concessions or commissions from the Selling Stockholders and/or the purchasers of the Shares for whom such broker-dealers may act as agents or to whom they sell as principals, or both (which compensation as to a particular broker-dealer might be in excess of customary commissions). See "Plan of Distribution."

The Company will not receive any of the proceeds from the sale of the Shares. The Company has agreed to bear certain expenses in connection with the registration of the Shares being offered and sold by the Selling Stockholders.

The Company's Common Stock is quoted on the Nasdaq National Market under the symbol "CCVD." On August 18, 1997 the average of the high and low price for the Common Stock was $7.625.

The Selling Stockholders and any broker-dealers or agents that participate with the Selling Stockholders in the distribution of the Shares may be deemed to be "underwriters" within the meaning of Section 2(11) of the Securities Act, and any commissions received by them and any profit on the resale of the Shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

PLAN OF DISTRIBUTION

The Company will receive no proceeds from this offering. The Shares offered hereby may be sold by the Selling Stockholders from time to time in transactions in the over-the-counter market, in negotiated transactions, or a combination of such methods of sale, at fixed prices which may be changed, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. The Selling Stockholders may effect such transactions by selling the Shares to or through broker-dealers, and such broker-dealers may receive compensation in the form of discounts, concessions or commissions from the Selling Stockholders and/or the purchasers of the Shares for whom such broker-dealers may act as agents or to whom they sell as principals, or both (which compensation as to a particular broker-dealer might be in excess of customary commissions).

In order to comply with the securities laws of certain states, if applicable, the Shares will be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the Shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

The Selling Stockholders and any broker-dealers or agents that participate with the Selling Stockholders in the distribution of the Shares may be deemed to be "underwriters" within the meaning of the Securities Act, and any commissions received by them and any profit on the resale of the Shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the Shares may not simultaneously engage in market making activities with respect to the Common Stock of the Company for a period of two business days prior to the commencement of such distribution. In addition and without limiting the foregoing, each Selling Stockholder will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M, which provisions may limit the timing of purchases and sales of shares of the Company's Common Stock by the Selling Stockholders.

Except as indicated, none of the Selling Stockholders has had a material relationship with the Company within the past three years other than as a result of the ownership of the Shares or other securities of the Company. Because the Selling Stockholders may offer all or some of the Shares which they hold pursuant to the offering contemplated by this Prospectus, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the Shares, no estimate can be given as to the amount of Shares that will be held by the Selling Stockholders after completion of this offering. The Shares offered by this Prospectus may be offered from time to time by the Selling Stockholders named below.

    Total                               =======

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware General Corporation Law authorizes a court to award or a corporation's Board of Directors to grant indemnification to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933, as amended (the "Securities Act"). Article VIII of the Registrant's Bylaws provides for mandatory indemnification of its directors and officers and permissible indemnification of employees and other agents to the maximum extent permitted by the Delaware General Corporation Law. The Registrant's Certificate of Incorporation provides that, pursuant to Delaware law, its directors shall not be liable for monetary damages for breach of the directors' fiduciary duty as directors to the Company and its stockholders. This provision in the Certificate of Incorporation does not eliminate the directors' fiduciary duty, and in appropriate circumstances equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware law. In addition, each director will continue to be subject to liability for breach of the director's duty of loyalty to the Company for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for actions leading to improper personal benefit to the director, and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law. The provision also does not affect a director's responsibilities under any other law, such as the federal securities laws or state or federal environmental laws. The Registrant has entered into Indemnification Agreements with its directors, a form of which was previously filed as an exhibit to the Company's Registration Statement on Form S-1 filed with the Securities and Exchange Commission on May 3, 1996. The Indemnification Agreements provide the Registrant's directors with further indemnification to the maximum extent permitted by the Delaware General Corporation Law.

ITEM 17. UNDERTAKINGS

The undersigned Registrant 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 the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that (i) and
(ii) do not apply if the Registration Statement is on Form S-3 or Form S-8, and the information required to be included in a post-effective amendment by (i) and (ii) is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the 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 which remain unsold at the termination of the offering.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission 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 Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant 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 registered, the Registrant 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 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.

The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or 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.

Re: REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

We have acted as counsel to CardioVascular Dynamics, Inc., a Delaware corporation (the "Company"), in connection with the registration of 120,000 shares of the Company's Common Stock (the "Shares"), as described in the Company's Registration Statement on Form S-3 filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Registration Statement").

In connection with this opinion, we have examined the Registration Statement and related Prospectus, the Company's Restated Certificate of Incorporation, as amended through the date hereof, the Company's bylaws and the originals, or copies certified to our satisfaction, of such records, documents, certificates, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below (the "Documents"). We are relying (without any independent investigation thereof) upon the truth and accuracy of the statements, covenants, representations and warranties set forth in such Documents.

On the basis of the foregoing, and in reliance thereon, we are of the opinion that the Shares have been duly authorized, are validly issued, fully paid and nonassessable.
