In December 2011, patients were also surgically implanted with gastric stimulation devices using electrodes coated with its proprietary material.

Biotectix Engineering director Jeffrey Hendricks said the BT DOT coating allowed their partner to use a much smaller electrode and lead assembly, which should result in reduced trauma to the patient, more reproducible orientation, and better placement.

"Early results also suggested the coated electrodes may enable faster and more effective stimulation of the GI tract," Hendricks said.

Biotectix GM James Arps said the first human implants of devices incorporating the BT DOT demonstrates the safety and efficacy of their proprietary coating materials.

"This is the first of a number of successful clinical studies that we hope to complete with our various partners in the coming year," Arps said.

The company said the treatment of additional patients is anticipated in the coming months.
