Magnetic shells for gastrointestinal endoscopic capsules as a means to control their motion
Wireless endoscopic video capsules are becoming largely used today for non-invasive explorations of the digestive tube. Traditional types of such capsules present a major drawback: their motion can not be controlled, since they proceed by means of the visceral peristalsis only. In order to enable a wireless control of their motion, this paper describes a new concept based on the use of external magnetic fields. The proposed technique exploits magnetic shells to be applied to traditional capsules prior to their use. The shells are capable of interacting with an imposed external magnetic field, providing a means to control the capsule movement and orientation. This solution is readily and cheaply applicable to any commercial endoscopic capsule, avoiding internal modifications. The paper reports results of preliminary bench tests. Prototype elastic shells made of a silicone elastomer mixed with magnetic particles were fabricated and tested with the Given Imaging M2A capsule in simplified experimental conditions. These tests permitted to demonstrate translations, rotations and roto-translations of the capsule/shell complex onto pieces of bovine tissues
Controlled navigation of endoscopic capsules: concept and preliminary experimental investigations
This paper describes a technique to control the navigation of traditional wireless endoscopic capsules and reports preliminary proof-of-concept investigations. These capsules are used for noninvasive explorations of the digestive tube. At present, their motion cannot be controlled and they proceed by means of the visceral peristalsis. In order to enable motion controls, the technique proposed here adopts magnetic shells which are to be applied to available capsules, immediately before their use. The shells are used to control the capsule movement by means of external magnetic fields. This solution is readily applicable to any endoscopic capsule, avoiding internal modifications. Prototype elastic shells made of silicone elastomers mixed with magnetic particles were fabricated. They were tested with the most diffused capsule (model M2A, Given Imaging Ltd., Yoqneam, Israel), by studying the performance of the capsule/shell complex in simplified experimental conditions. Bench tests permitted to demonstrate controlled translations, rotations, and rototranslations of the capsule/shell complex within tubular structures coated with pieces of bovine tissues. The use of a new instrumentation, recently developed for cardiovascular treatments, is proposed as a potential means enabling the application of controlled magnetic fields for intrabody navigations
