The invention features a cuff device comprising a support having a first end, a second end and an elongated body in between; connection means for electrical, magnetic and/or fluidic magnetic connection with external devices; at least one of i) an electrode and/or electronic component operatively connected with said connection means configured to electrically interface with a biological tissue and ii) a channel having an inlet, an outlet and an elongated body in between operatively connected with said connection means via said inlet and configured to fluidically interface with a biological tissue via said outlet; and at least one buckle configured to receive said first end and permit the sliding therein of said elongated body so to close and lock the cuff electrode device at desired positions, characterized in that said support is stretchable.

A flow control apparatus for controlling a flow of fluid and/or other matter in a lumen formed by a tissue wall of a patient's organ. The apparatus comprises a control device adapted to control contraction of the tissue wall to influence the flow in the lumen. The apparatus further comprises an implantable constriction device adapted to gently and simultaneously constrict a series of wall portions comprising three or more wall portions of the tissue wall to influence the flow in the lumen, wherein the constriction device gently constricts the series of wall portions by constricting the series of wall portions to a constricted state in which the blood circulation in the constricted series of wall portions is substantially unrestricted and the flow in the lumen is at least restricted, and an implantable energized stimulation device adapted to individually and independently stimulate a selected wall portion of the series of wall portions, comprising three or more wall portions.

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.

A system for stimulating the release of satiety hormone in a subject comprises a stimulus device which is implantable in the subject and adapted to apply an electrical stimulus to a tissue of a gastrointestinal system of said subject, and a detection device which is implantable in the subject and adapted to continuously monitoring at least one of a mechanical characteristic and an electrical characteristic of the subject to detect an ingestion of food by said subject, wherein the detection device cooperates with the stimulus device such that the stimulus device applies said electrical stimulus in response to a detected ingestion of food.

Systems and methods for gastrointestinal electrical stimulation to treat abnormalities in gastrointestinal motility are provided. In some embodiments, a system for relieving ileus includes an intraluminal catheter comprising: a catheter body having a proximal tip and a distal tip and a duodenal portion proximal to the distal tip of the catheter; and at least one electrode pair disposed along the duodenal portion of the intraluminal catheter, the at least one electrode pair being configured to detect a sensing information indicative of myoelectric activity of a patient and to provide stimulation energy; a sensing system in communication with the at least one electrode pair to receive the sensing information; and an energy delivery system in communication with the at least one electrode pair and the sensing system, the electrical energy delivery system being configured to delivery energy to the patient through the at least one second electrode pair based on the sensing information from the sensing system.

An enteral feeding tube capable of delivering nutrients and/or medications to a patient at multiple points in the gastrointestinal tract and/or aspirating the gastrointestinal tract, comprising two or more channels each with at least one opening, said channels running parallel to the other until one channel ends, each channel keeping the fluid separated from the other channel, said channels being open at the proximal end and closed or open at the distal end and each channel having one or more perforations of same or variable size.

The invention relates to a closed loop system which is used in modulating gastric activity. By appropriate deployment of the components of the system, one can monitor and modulate slow waves in the gastrointestinal system of a subject.

Described and disclosed herein are various embodiments of methods, systems, devices and components relating to miniaturized gastric electrical stimulators (GESs) configured for implantation in a patient's stomach.

The present disclosure relates to a system for treating a patient having a disorder related to a patient's intestine (100), comprising one or more electrical stimulation devices (10) having one or more electrodes (11) for electrically stimulating muscle or neural tissue of the intestine, wherein each of the one or more electrical stimulation devices (10) comprises a wireless energy receiver (R) configured to receive energy for stimulating the muscle or neural tissue wirelessly.

Disclosed herein are methods, systems, and devices for oral drug delivery. The method generally involves orally administering a drug delivery device to the subject in need of treatment and triggering iontophoresis. The drug delivery device includes one or more active agents for delivery to the subject. The method can include the step of delivering the active agent to the intestinal mucosa after iontophoresis is triggered at the site, or simultaneously as iontophoresis is applied at the site. After the active agent(s) are delivered, the drug delivery device can be released from the intestinal mucosa. The iontophoresis can be performed for a period of time and at an electrical current that is effective to improve permeability of the one or more active agents across the intestine compared to orally administering the same drug delivery device in the absence of iontophoresis.
