Endoscopic excision of large capsulated lipomas

British Journal of Plastic Surgery, 1996
The technique of endoscopic excision of large capsulated lipomas is presented and the versatility of this method is discussed based on our clinical experience. We have applied this new technique in 6 cases. In all cases the lipoma was completely removed in one piece through a single incision, up to 1.5 cm in length.

Endoscopic placement of the small-bowel video capsule by using a capsule endoscope delivery device

Gastrointestinal Endoscopy, 2007
Capsule endoscopy performed via the traditional peroral route is technically challenging in patients with dysphagia, gastroparesis, and/or abnormal upper-GI (UGI) anatomy.To describe the indications and outcomes of cases in which the AdvanCE capsule endoscope delivery device, which has recently been cleared by the Food and Drug Administration, was used.

SoC for Capsule Endoscope

2013
TAn application specific SoC with bidirectional wireless communication for the wireless capsule endoscope system is presented in this chapter. The SoC has an integrated ultra-low-power transceiver featured with asymmetrical data rate (3Mbps transmitting and 64kbps receiving). A dedicated ARQ scheme is designed to maintain an adequately low BER for data

Non-endoscopic Capsules

Development of swallowable wireless sensing capsules dates back to 1964 with the advent of the Heidelberg pH capsule. Transmission of data from the inside of the body by radiofrequency is still the mainstay of action. However, multiple sensors have been developed in the meantime and broadened the range of application: this includes sensors for ...

The ultra wideband capsule endoscope

2013 IEEE International Conference on Ultra-Wideband (ICUWB), 2013
One of the most innovative applications of wireless technology in medicine is the capsule endoscope (CE). This electronic device helps to examine hard-to-reach parts of the gastrointestinal (GI) tract with significantly less discomfort for the patient than traditional endoscopic methods based on the insertion of flexible tubes.

Endoscopic retrieval of a capsule endoscope from a Zenker’s diverticulum

Diseases of the Esophagus, 2005
We report a case of a capsule endoscope lodged within a Zenker's diverticulum. The capsule was safely removed endoscopically. Safe re-insertion of the capsule was achieved using an overtube placed with a Savary dilator. While capsule endoscopy should be avoided in patients with large esophageal diverticula or dysphagia, this method may be used to ...

Microrobots for a capsule endoscope

2009 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2009
Various actuators have been studied to develop micro robots for a capsule endoscope. In particular, some locomotive mechanisms based on the SMA (Shape Memory Alloy) actuator, the PZT actuator, the Polymer actuator, and the micro motor have been actively studied to fabricate a microrobot for a capsule endoscope.

Small intestinal capsule biopsy under endoscopic guidance

Gastrointestinal Endoscopy, 1983
Small intestinal mucosal biopsy is of recognized value in the evaluation of suspected malabsorption. 1-3 Conventional techniques of peroral suction capsule jejunal biopsy are often time consuming and generally require fluoroscopy and special positioning of the patient to guide the capsule through the pylorus.
