Autonomous telemetric capsule to explore the small bowel

Area of Science:

• Gastroenterology
• Medical Devices
• Biomedical Engineering

Background:

• Studying the small bowel presents challenges due to its inaccessibility.
• Existing methods for small bowel investigation are often invasive or provide limited real-time data.

Purpose of the Study:

• To develop and validate a novel intestinal telemetric capsule for in-situ small bowel monitoring.
• To enable precise location tracking, intraluminal fluid sampling, and targeted drug delivery within the small intestine.

Main Methods:

• Development of a swallowable capsule (11 mm diameter, 39 mm length) with location detection, radiotransmission, and a lithium battery.
• Incorporation of an interchangeable tip for remote-controlled fluid sampling (0.5 ml) or liquid substance release (1 ml).
• Utilizing radiotransmission to continuously monitor capsule progression, direction, and velocity through the small bowel.

Main Results:

• The capsule successfully transmits its precise location within the small bowel.
• Continuous monitoring of distance from the pylorus, direction, and velocity of progression is achieved.
• Remote-controlled sampling and substance release at predetermined locations are demonstrated.

Conclusions:

• The developed intestinal telemetric capsule offers a unique solution for real-time small bowel investigation.
• This technology facilitates advanced gastrointestinal research, including diagnostics and targeted pharmacology.
• The capsule's precise location tracking capability is a significant advancement in endoscopic technology.
