20140243593 | Implantable Electrical Stimulation Leads - 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. | 08-28-2014 |
20140249594 | Device and Implantation System for Electrical Stimulation of Biological Systems - The present specification discloses devices and methodologies for the treatment of transient lower esophageal sphincter relaxations (tLESRs). Individuals with tLESRs may be treated by implanting a stimulation device within the patient's lower esophageal sphincter and applying electrical stimulation to the patient's lower esophageal sphincter, in accordance with certain predefined protocols. The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow and have improved energy storage requirements. | 09-04-2014 |

The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow and have improved energy storage requirements. | 02-26-2015 |
20150066109 | Methods and Systems of Electrode Polarity Switching in Electrical Stimulation Therapy - Methods for electrically stimulating body tissues to improve function or reduce symptoms provide an electrical stimulation system having two or more electrodes that are capable of being switched independently from a hyperpolarizing (depolarizing) state to a hypopolarizing state. Multiple combinations of hyperpolarizing electrodes and hypopolarizing electrodes are created by polarity switching to determine a polarity configuration having the best performance as determined by symptom reporting and clinical diagnostic tests. Polarity switching is triggered manually or is programmed to be switched automatically. Determining the configuration providing electrical stimulation resulting in the greatest benefit allows the system to be operated with one or more electrodes in a hypopolarizing state, thereby reducing energy requirements, tissue tolerance, and tissue fatigue. | 03-05-2015 |
20150119646 | Lead Implantation Method - A method of laparoscopically implanting an electrically stimulating lead proximate the lower esophageal sphincter (LES) of a patient includes delivering the lead through a port of a laparoscope inserted into the abdominal cavity of the patient through an incision in the abdominal wall. The stimulating electrode is implanted in or proximate the muscularis layer of the lower esophageal wall to treat esophageal reflux disease (GERD). The lead includes a needle and suture at its distal end for pulling the electrode into the muscular wall of the LES. Clips are applied to the suture attached to the distal end of the lead to prevent retrograde movement of the electrode. The lead also includes an anchoring member for anchoring the portion of the lead proximal to the electrode. The method and lead used with the method allow the surgeon to work within the confined anatomy present at the gastroesophageal junction and prevents backwards movement and dislodgment of the electrode. The implantation procedure can be combined with a hiatal hernia repair to repair the hernia and prevent recurrence of a hiatal hernia. | 04-30-2015 |

20150297885 | Implantable Electrical Stimulation Leads - Implantable electrical stimulation leads for the treatment of biological conditions include a lead body with an electrical connector at one end and multiple in-line electrodes at the other end. The lead body has a length ranging from 350 mm to 630 mm to allow for implantation from an incision site further removed from the final positioning site of the electrodes. One lead has a suture loop extending from the most distal electrode for pulling the lead through the working channel of an endoscope. Another lead has a length of suture with a free end attached to the most distal electrode. Yet another lead has a length of suture attached to the most distal electrode at one end and a needle at the other end. The needle has a curve designed to facilitate maneuvering in confined anatomy. The lead having the needle is designed to be implanted laparoscopically. | 10-22-2015 |
20160001071 | Device and Implantation System for Electrical Stimulation of Biological Systems - The present specification discloses devices and methodologies for the treatment of GERD. Individuals with GERD may be treated by implanting a stimulation device within the patient's lower esophageal sphincter and applying electrical stimulation to the patient's lower esophageal sphincter, in accordance with certain predefined protocols. The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow, have improved energy storage requirements, enable improved LES function while concurrently delivering additional health benefits, and enable improved LES function post stimulation termination. | 01-07-2016 |
