Magnet and wire remodeling for the treatment of candy cane syndrome: first case series of a new approach (with video).

Background And Aims: Candy cane syndrome (CCS) is an adverse event (AE) from gastrectomy or gastric bypass and end-to-side anastomosis to a jejunal loop. Preferential passage of food to the blind loop induces early satiety, pain, and regurgitation. An endoscopic device that combines 2 magnets and a self-retractable wire was designed to perform progressive septotomy with marsupialization.

Magnets and a self-retractable wire for endoscopic septotomies: from concept to first-in-human use.

Background: A medical device that allows simple and safe performance of an endoscopic septotomy could have several applications in the gastrointestinal (GI) tract. We have developed such a device by combining two magnets and a self-retractable wire to perform a progressive septotomy by compression of the tissues. We describe here the concept, preclinical studies, and first clinical use of the device for the treatment of symptomatic epiphrenic esophageal diverticulum (EED).

Optimization and assessment of a novel gastric electrode anchoring system designed to be implanted by minimally invasive surgery.

A novel electrode anchoring design and its implantation procedure, aiming for a minimally invasive solution for gastric electrical stimulation, are presented. The system comprises an anchor made of a flexible body embedding two needle-shaped electrodes. The electrodes can easily switch from a parallel position - to pierce the stomach - to a diverging position - enabling them to remain firmly anchored into the muscular layer of the stomach.

In Vivo Validation of a Less Invasive Gastrostimulator.

Gastrointestinal stimulator implants have recently shown promising results in helping obese patients lose weight. However, to place the implant, the patient currently needs to undergo an invasive surgical procedure. We report a less invasive procedure to stimulate the stomach with a gastrostimulator.

Power Strategy in DC/DC Converters to Increase Efficiency of Electrical Stimulators.

Power efficiency is critical for electrical stimulators. Battery life of wearable stimulators and wireless power transmission in implanted systems are common limiting factors. Boost DC/DC converters are typically needed to increase the supply voltage of the output stage.

Design and Implementation of a Less Invasive Gastrostimulator.

Gastrointestinal stimulator implants have recently shown positive results in helping obese patients lose weight. However, to place the implant, the patient currently needs to undergo an invasive surgical procedure. Our team is aiming for a less invasive procedure to stimulate the stomach with a gastrostimulator.
