Item 1.	Security and Issuer
This statement relates to the common stock, no par value per share (the “Common Stock”), of IOMED, Inc., a Utah corporation (the “Issuer”). The Issuer’s principal executive office is located at 2441 South 3850 West, Salt Lake City, Utah 84120.
Item 2.	Identity and Background
(a) This statement is filed by Ridgestone Corporation, a Delaware corporation. Ridgestone Corporation is sometimes referred to herein as the “Reporting Person.” The Reporting Person disclaims membership of a “group” within the meaning of Rule 13d-5(b) promulgated under the Securities and Exchange Act of 1934, as amended (the “Act”).
Abbott L. Brown is Ridgestone’s Chairman of the Board, Chief Executive Officer and founding shareholder. Mr. Brown was an executive officer and member of the Board of Directors of Global Crossing Ltd. from 1998 to 2000. From 1994 to 1998, Mr. Brown was managing director and chief financial officer of Pacific Capital Group, a merchant banking firm.

(b) The principal business address of the Reporting Person is 10877 Wilshire Blvd., Suite 2000, Los Angeles, CA 90024.
(c) Ridgestone is a private investment company focused on owning, operating and financing middle market companies. Ridgestone’s directors and executive officers are Abbott L. Brown, Linda L. Brown and D. Stephen Antion.

(e) None of the persons or entities named in this Item has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.
(f) Each of the above-named individuals is a United States citizen.
Item 3.	Source and Amount of Funds or Other Consideration
The Reporting Person used $1,952,150 from available capital to purchase the shares of Common Stock and $1,050,217 from available capital to purchase Series D Non-Voting Preferred Shares.

On May 25, 2006, the Reporting Person converted all of the Series D Non-Voting Preferred Shares to Common Stock.
Item 4.	Purpose of Transaction
The Reporting Person purchased the Common Stock and Series D Non-Voting Preferred Shares (which has been converted into Common Stock) based on the Reporting Person’s belief that the Common Stock at current market prices is undervalued and represents an attractive investment opportunity. As noted in the Reporting Person’s Schedule 13D filing of April 8, 2005, the Reporting Person believes the Issuer’s Common Stock is substantially undervalued. Depending upon overall market conditions, other investment opportunities available to the Reporting Person and the availability of Common Stock (or equivalents) at prices that would make the purchase of additional Common Stock desirable, the Reporting Person may endeavor to increase its position in the Issuer through, among other things, the purchase of Common Stock on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Person may deem advisable.
The Reporting Person does not as of the date of this filing have any specific plans or proposals which would relate to or result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon completion of any of the actions discussed above. The Reporting Person intends to review its investment in the Issuer on a continuing basis and engage in discussions with management and the Board of Directors of the Issuer concerning the business, operations and future plans of the Issuer. The Reporting Person will evaluate ways to maximize shareholder value. The Reporting Person continues to advocate a substantial distribution of cash to shareholders by the Issuer, in addition to a potential sale of the business, as the best means for enhancing shareholder value. Depending on various factors including, without limitation, the Issuer’s financial position and strategy, the price levels of the Common Stock, conditions in the securities markets and general economic and industry conditions, the Reporting Person may in the future take such actions with respect to its investment in the Issuer as it deems appropriate including, without limitation, making proposals to the Issuer, purchasing additional Common Stock, selling some or all of its Common Stock, hedging or similar transactions with respect to the Common Stock or changing its intention with respect to any and all matters referred to in Item 4. On May 26, 2006, the Issuer elected Stephen Antion to its Board of Directors. Mr. Antion is the President of the Reporting Person.
Item 5.	Interest in Securities of the Issuer
(a) and (b) Based upon information contained in the Issuer’s most recently filed Form 10-QSB filed with the Commission on May 15, 2006, as of April 30, 2006 there were 7,153,455 shares of Common Stock issued and outstanding. Subsequent to this date, the Reporting Person converted 446,901 shares of Series D Non-Voting Preferred Shares of the Issuer, which were convertible on a one-for-one basis, into Common Stock. The Reporting Person has used the number from the Form 10-Q, as adjusted by the conversion of the Series D Non-Voting Preferred Shares, to determine its individual percentage interest in the Issuer’s Common Stock.
The aggregate number of shares of Common Stock of the Issuer that Ridgestone Corporation owns is 1,505,301 which constitutes 19.8% of the outstanding shares of Common Stock. Abbott L. Brown and Linda Brown, the directors of Ridgestone, share

the power to vote or to direct the vote of and to dispose of or to direct the disposition of all such shares.
(c) During the past 60 days, Ridgestone Corporation has had no transactions in the Common Stock of the Issuer other than the conversion to Common Stock of the 446,901 shares of Series D Non-Voting Preferred Shares of the Issuer.
(d) The Reporting Person affirms that no person other than such Reporting Person has the right to receive or the power to direct the receipt of dividends from or the proceeds from the sale of the shares owned by the Reporting Person.
(e) Not applicable.
Item 6.	Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
Christopher S. Kiper is an employee of Ridgestone Corporation. He and D. Stephen Antion have profit participations in connection with Ridgestone Corporation’s ownership of the Issuer’s Common Stock. Linda L. Brown is the wife of Abbott L. Brown.
