“…The implantable stimulator system (Figure 1A) includes (1) the IGS with the stimulation stage, the wirelessly chargeable battery, and the telecommunication module, (2) the flexible anchor to position two stimulating electrodes into the gastric wall and (3) the control box to charge and communicate with the IGS for control and adaptation of the implant parameters. The anchor body contains two stainless steel electrodes, held 1 cm apart, and is connected to the IGS with a cable ending with Craggs connectors (Finetech Medical LTD, UK) 32 . The anchor is intended to be placed in a less‐invasive way through single incision percutaneous access with a single step release, 33 with (1) the summarized procedure and (2) the tool illustrated in Figure 1B.…”

Background: Gastric electrical stimulation (GES) has been studied for decades as a promising treatment for obesity. Stimulation pulses with fixed amplitude and pulse width are usually applied, but these have limitations with regard to overcoming habituation to GES and inter-subject variation. This study aims to analyze the efficacy of an adaptive GES protocol for reducing food intake and maintaining lean weight in dogs.Methods: Six beagle dogs were implanted with a remotely programmable gastric stimulator. An adaptive protocol was designed to increase the stimulation energy proportionally to the excess of food consumption, with respect to the dogs' maintenance energy requirements. After surgery and habituation to experimental conditions, the dogs went through both a control and a stimulation period of 4 weeks each, in a randomized order. The stimulation parameters were adapted daily.Body weight, food intake, food intake rate, and postprandial cutaneous electrogastrograms (EGG) were recorded to assess the effect of adaptive GES. Results: Adaptive GES decreased food intake and food intake rate (p < 0.05) resulting in weight maintenance. In the absence of GES, the dogs gained weight (p < 0.05). Postprandial EGG dominant frequency was accelerated by GES (p < 0.05). The strategy of adapting the stimulation energy was effective in causing significant mid-term changes. Conclusion:Adaptive GES is effective for reducing food intake and maintaining lean weight. The proposed adaptive strategy may offer benefits to counter habituation and adapt to inter-subject variation in clinical use of GES for obesity.

“…There is a particular trade-off between connector size and channel count. Neural electrode designs with 10's to 100's of electrode sites are common, while long term implantable connectors typically have fewer than 10 channels [1], [3], [4].…”

“…The connector mating surfaces, and connections to any cables or implants, must be protected from the moist, corrosive, environment of the body. Protection methods for implantable connectors include silicone encapsulation [4], epoxy encapsulation [5], acrylic embedding (as part of a head mounting) [6], compression sleeves [7], and metal-in-ceramic hermetic feedthroughs [8].…”

“…long-term implantability, reusability and a high channel count. Pin and socket designs as the Craggs connector [7] and the in-line connector [1] perform well in implants for bladder control [8], anterior root stimulation [9] and other neuroprostheses [10]. However, upscaled to high channel counts this concept would take up too much volume.…”

Further development of active implantable medical devices (AIMDs) coming along with higher channel counts and improved maintainability raises the requirements for implantable connectors in such systems. We developed a concept for an implantable multichannel connector. Contact pads manufactured by laser-structuring that are embedded into a silicone substrate serve as contact partners. Processing features specific to two laser technologies were exploited not only to cut the materials but also to 3D-shape the surfaces of the contact pads. First tests for the long-term behavior show stable contact and isolation properties during 6 weeks of soaking at elevated temperature.
