Late last month, Boston Scientific reported quarterly earnings that had a few bright spots -- among them the performance of its neuromodulation business, where sales increased 17 percent to $84 million.

It’s true the business is relatively small in the scheme of things. But a cornerstone technology – using a pacemaker-like device to zap the spinal cord of chronic pain sufferers – has a new online “learning institute” for doctors in search of information about the treatment.

This doesn’t appear to be patient-oriented, since much of the information is highly technical (at least to this humble blogger’s eyes). Witness a link to a study called “Dorsoventral Variability in SCS Lead Placements: Correcting for Dorsalventral Variability in SCS Lead Placement in a Computational Model.”

Natick, Mass.-based Boston Sci, with some 5,000 employees in the Twin Cities, unveiled the website at the International Spine Intervention Society meeting last week in Chicago, as well as an iPhone/iPad app that provides technical info for health care providers using spinal cord stimulation to treat pain patients.
