Endoscopic Procedures III: Video Capsule Endoscopy

582
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Wireless capsule endoscopy (WCE) is now steerable. A new electromagnetic locomotion system allows active capsule movement for targeted gastrointestinal diagnosis and treatment.

Area of Science:

  • Medical Devices
  • Gastroenterology
  • Robotics

Background:

  • Traditional endoscopic methods struggle with small bowel visualization.
  • Wireless capsule endoscopy (WCE) improved diagnostics but lacks maneuverability.
  • Passive WCE cannot be precisely controlled or positioned within the GI tract.

Purpose of the Study:

  • To develop a novel locomotion system for active wireless capsule endoscopy.
  • To enable targeted navigation and positioning of capsules within the gastrointestinal tract.
  • To explore advanced applications like precise drug delivery and tissue sampling.

Main Methods:

  • Implementation of a new locomotion methodology for WCE systems.
  • Utilizing an electromagnetic platform to generate a dynamic magnetic field for capsule control.
