A Prototype Design of a Wireless Capsule Endoscope

Applied Bionics and Biomechanics, 2006
Diseases of the gastrointestinal tract, such as intestinal bleeding and ulceration, are very common. To determine the location of the disease, as well as to diagnose the problem, endoscopy is performed. A wireless capsule endoscope is a pill-sized device

Endoscopic findings in patients with Shwachman–Diamond syndrome: A report from the North American Shwachman–Diamond syndrome registry

JPGN Reports, EarlyView.
Abstract Objectives Shwachman–Diamond syndrome (SDS) is an inherited bone marrow failure disorder, and its endoscopic phenotype is poorly defined. We sought to characterize endoscopic findings in patients with genetically confirmed SDS. Methods Retrospective registry study of 45 patients with biallelic Shwachman–Bodian–Diamond syndrome mutations and ...

Additional lateral meniscus centralization reduces residual anterolateral rotatory instability after anterior cruciate ligament reconstruction and lateral meniscus repair

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study aimed to examine the effects of lateral meniscus (LM) centralization on anterolateral rotational stability in patients with anterior cruciate ligament (ACL) and LM injuries. The hypothesis was that performing LM repair and centralization on knees with LM lesions would control anterolateral rotatory instability (ALRI ...

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Endoscopy-assisted capsule endoscopy in patients with swallowing disorders

, 2004
Capsule endoscopy (CE) has greatly facilitated the diagnosis of small-bowel lesions in patients with obscure gastrointestinal bleeding [1]. It was recently reported by Hollerbach et al. [2] that endoscopically assisted video capsule endoscopy facilitates

Driving Drugs Deeper: Force‐Driven Microneedle Systems for Active Therapy and Their Road Towards Clinical Implementation

Small, EarlyView.
Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

Imaging Fluorophore-Labelled Intestinal Tissue via Fluorescence Endoscope Capsule

Proceedings, 2018
The authors have developed a wireless fluorescence imaging capsule endoscope, potentially capable of detecting early signs of disease in the human intestine which can be missed by white-light imaging (WLI) capsule endoscopy (Figure 1).

Small Bowel Lesions and Bleeding Risk in Hemodialysis Patients: A Narrative Review

Hemodialysis International, EarlyView.
ABSTRACT Background Gastrointestinal bleeding is very common among hemodialysis patients. This high bleeding risk is caused by uremic platelet dysfunction, vascular fragility, intradialytic hemodynamic instability, and widespread antithrombotic therapy.
