Magnetic Actuator for a Capsule Endoscope Navigation System

Implemented a wireless communication system for VGA capsule endoscope.

Recently, several medical devices that use wireless communication are under development. In this paper, the small size frequency shift keying (FSK) transmitter and a monofilar antenna for the capsule endoscope, enabling the medical device to transmit VGA-size images of the intestine. To verify the functionality of the proposed wireless communication system, computer simulations and animal exper...

Closed Loop Control of a Tethered Magnetic Capsule Endoscope

Magnetic field gradients have repeatedly been shown to be the most feasible mechanism for gastrointestinal capsule endoscope actuation. An inverse quartic magnetic force variation with distance results in large force gradients induced by small movements of a driving magnet; this necessitates robotic actuation of magnets to implement stable control of the device. A typical system consists of a s...

Electromagnetic Control System for Capsule Navigation: Novel Concept for Magnetic Capsule Maneuvering and Preliminary Study

The gastrointestinal tract is home of some of the most deadly human diseases. The main problems are related to the difficulty of accessing it for diagnosis or intervention and concomitant patient discomfort. The flexible endoscopy technique has established itself in medical practice due to its high diagnostic accuracy and reliability; however, several technical limitations still remain and the ...

6-D Localization of a Magnetic Capsule Endoscope Using a Stationary Rotating Magnetic Dipole Field

Since the introduction of passive commercial capsule endoscopes, researchers have been pursuing methods to control and localize these devices, many utilizing magnetic fields [1, 2]. An advantage of magnetics is the ability to both actuate and localize using the same technology. Prior work from our group [3] developed a method to actuate screw-type magnetic capsule endoscopes in the intestines u...
