"The Winston-Salem, N.C.-based anesthesiologist and pain specialist discovered - quite by accident - that a device which he used to treat chronic back pain may also produce orgasms in patients. He has just patented this unexpected use of the device and is trying persuade the product manufacturer to market the device to help women who have trouble reaching orgasm."
