Item 4.                      Purpose of Transaction

The Reporting Persons, who have, as of August 9, 2012, formed a group known as Concerned Aetrium Shareholders (“CAS”), purchased Shares based on the belief that such securities, when purchased, were undervalued and represented an attractive investment opportunity.  Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase or sale of Shares desirable, the Reporting Persons may endeavor to increase or decrease their position in the Issuer through, among other means, the purchase and sale of shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.  As of the date hereof, Mr. Eberwein has informally offered to sell certain of the shares held by him to certain other of the Reporting Persons in private transactions.

The purposes of the acquisitions of the Common Stock were investment. The acquisitions of the Common Stock were made in the ordinary course of business.

The Reporting Persons have had discussions regarding plans to improve the performance of the Company, including a brief discussion of the performance of the members of the board of directors of the Issuer.  On July 11, 2012 Mr. Vetter met with Joseph Levesque, Chief Executive Officer of the Issuer and Douglas Hemer, Chief Administrative Officer and member of the board of directors and discussed concerns regarding the company’s performance.  The Reporting Persons currently seek to engage the Issuer’s board of directors in discussions concerning corporate strategy, on-going business operations, potential asset sales, membership of the board of directors, and company management, among other topics.

Consistent with their investment purpose, the Reporting Persons may engage in communications with one or more stockholders of the Issuer, one or more officers of the Issuer, one or more members of the board of directors of the Issuer, and/or one or more representatives of the Issuer regarding the Issuer, including but not limited to the Issuer’s operations and the foregoing current plans of the Reporting Persons. The Reporting Persons may discuss ideas that, if effected may result in a change of the current plans and in the acquisition by persons of additional Common Stock of the Issuer, the disposition of Common Stock of the Issuer, an extraordinary corporate transaction involving the Issuer and/or other changes in the board of directors of the Issuer, its operations or its corporate structure.

No Reporting Person has any present plan or proposal which would relate to, or could result in, any of the matters referred to in subparagraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D, except as set forth herein or such as would occur upon or in connection with the completion of, or following, any of the actions discussed herein. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto.

This Schedule 13D is not a solicitation of any action by stockholders of the Issuer. If a proxy statement is completed and filed, stockholders are advised to read the proxy statement when it becomes available because it will contain important information, and stockholders should rely on such proxy statement and not on this Schedule 13D.
