Abstract:
1. A system for delivering stimulation to a target region in a body having lymphatic vessels and a gastrointestinal (GI) tract including GI organs and nerves innervating the GI organs, the target region including portions of the GI tract, the system comprising: a first implantable lead having a first distal end, a first proximal end, and a first elongate lead body between the first distal end and the first proximal end; a first electrode assembly incorporated into the first implantable lead, the first electrode assembly including a first electrode base configured to be implanted into one of the lymphatic vessels and a first stimulation electrode and a second stimulation electrode on the first electrode base away from the first distal end, the first electrode base including a bias disposed at a location of the first stimulation electrode on the first electrode base, the bias including a helix-shaped portion of the first electrode base, the bias configured to selectively cause a portion of the one of the lymphatic vessels adjacent to the target region of stimulation to substantially alter its natural path to cause the first stimulation electrode to contact the portion of the one of the lymphatic vessels with the altered natural path and maintain the contact between the portion of the one of the lymphatic vessels and the target region after an implantation of the first electrode assembly; and a second electrode base disposed at the distal end of said first implantable lead and located distally of said bias in said first electrode base; and an implantable medical device configured to be connected to the first proximal end of the first implantable lead, the implantable medical device including:
