Obesity is a chronic disease with an exponentially increasing incidence rate, and its negative effects are well documented in numerous studies. As a result, the importance of bariatric therapy cannot be overemphasized, and many bariatric treatment methods with varying mechanisms have been developed. Of the available treatment methods, intragastric balloons, introduced in the 1980s, have been shown to be a safe and effective treatment modality; various intragastric balloon products have been developed and are currently being widely used in clinical settings. However, the disadvantages of intragastric balloons, such as unclear long-term weight loss benefits and complications experienced during insertion and removal, preclude their wider use. In this review, we discuss different intragastric balloon products, focusing on those under clinical investigation, and suggest future research directions.

“…[194][195][196][197] To implement the magnetic actuation in surgical tools, magnetic generators are externally located outside the patient's abdominal wall where the actuation force/torque is magnetically transmitted from outside via the abdominal wall. [198][199][200] This means that on-board electromagnetic motors or cables are eliminated. Many magnetic actuation methods have been studied for use in surgical systems.…”

Surgical robots have had clinical use since the mid‐1990s. Robot‐assisted surgeries offer many benefits over the conventional approach including lower risk of infection and blood loss, shorter recovery, and an overall safer procedure for patients. The past few decades have shown many emerging surgical robotic platforms that can work in complex and confined channels of the internal human organs and improve the cognitive and physical skills of the surgeons during the operation. Advanced technologies for sensing, actuation, and intelligent control have enabled multiple surgical devices to simultaneously operate within the human body at low cost and with more efficiency. Despite advances, current surgical intervention systems are not able to execute autonomous tasks and make cognitive decisions that are analogous to those of humans. Herein, the historical development of surgery from conventional open to robotic‐assisted approaches with discussion on the capabilities of advanced intelligent systems and devices that are currently implemented in existing surgical robotic systems is reviewed. Also, available autonomous surgical platforms are comprehensively discussed with comments on the essential technologies, existing challenges, and suggestions for the future development of intelligent robotic‐assisted surgical systems toward the achievement of fully autonomous operation.

“…In addition, in vitro data suggested that the hydrogel device could also be used for ultra‐long sustained drug delivery. Inflatable capsule devices could be used for bariatric intervention . While conventional intragastric balloons are an efficient way to treat obesity, they typically require an invasive procedure using a catheter or endoscope to insert and remove the intragastric balloons from the stomach.…”

Since the advent of ingestible temperature sensors and capsule endoscopes, rapid advances in electronics, robotics, nanotechnology, and material sciences have opened the door for the development of novel medical ingestible robots. The untethered robots provide direct, non-invasive access to the entire gastrointestinal (GI) tract. Furthermore, the tissues, gases, and fluids of the gastrointestinal lumen contain a multitude of biomarkers indicative of gut diseases and health. Ingestible medical robots equipped with advanced imaging and sensing techniques can enable the diagnosis and monitoring of diseases, while providing a better pathophysiological understanding of gastrointestinal disorders. In addition, various robotic actuation mechanisms in the macro-and microscale can realize enhanced drug delivery and surgical interventions for the treatment of diseases. In this paper, an overview of recent advances in ingestible robots toward imaging, sensing, drug delivery, and surgical applications in the GI tract is provided. Key challenges and strategies for the development of novel ingestible robots and future directions of ingestible robots toward precision medicine are also discussed.
