Intestinal retentive systems - recent advances and emerging approaches

Area of Science:

• Biomedical Engineering
• Gastroenterology
• Materials Science

Background:

• Intestinal retentive devices (IRDs) are designed for prolonged anchoring within the gastrointestinal tract.
• These devices hold potential for advanced applications such as sustained oral drug delivery, indwelling sensors, and real-time diagnostics.

Purpose of the Study:

• To review the current state-of-the-art in intestinal retentive devices (IRDs).
• To identify challenges and chart a path forward for the design and development of future IRDs.
• To explore potential synergies between IRDs and other medical device technologies.

Main Methods:

• Review of existing literature on IRD materials, retention mechanisms, and testing methodologies.
• Analysis of design and deployment challenges, including precise localization, secure anchoring, and safe removal.
• Exploration of interdisciplinary innovation requirements involving materials, anchoring, and clinical input.

Main Results:

• The development of IRDs faces significant challenges in deployment, secure anchoring, and retrieval.
• Advancement requires interdisciplinary collaboration focusing on novel materials, innovative anchoring mechanisms, and user-centered design.
• Existing test beds are critical for evaluating IRD efficacy and retention mechanisms.

Conclusions:

• Future IRD development necessitates a focus on materials science, advanced anchoring strategies, and robust testing protocols.
• Clinical input is essential for designing effective and safe IRDs for long-term gastrointestinal residence.
• Synergistic integration with other medical device technologies presents promising avenues for novel IRD applications.
