Luminetx Veinviewer pledged for loan

Memphis-based Luminetx has pledged as loan collateral the intellectual property, including patents, associated with its Veinviewer technology. The lender, Christie Digital Systems, is a sub of a Japanese company. Memphis Daily News reports Veinviewer's inventor, Herb Zeman, and other shareholders had considered attempting to take over the company and securing investment capital, to avoid a loan, but that did not happen.
