Abstract
An implantable electrical stimulation lead for the treatment of biological conditions includes a lead body with an electrical connector at one end and a pair of monopolar branches at the other end. The lead body has a length ranging from 390 mm to 490 mm to allow for implantation from an incision site further removed from the final positioning site of the electrodes. The branches have lengths ranging from 50 mm to 120 mm for the both branches. These lengths facilitate successful laparoscopic implantation at sites with confined anatomy, such as, near the gastroesophageal junction. The branches include needles and sutures at their ends for suturing anchors positioned on the branches to surrounding tissue. The needles have curves designed to facilitate maneuvering in confined anatomy. A separate lead includes a suture loop connecting the ends of the first and second branches rather than needles. The loop is used to pull the lead through the working channel of an endoscope. The anchors on the lead are porous and allow for the ingrowth of surrounding tissue for fixing the branches in place.
