Glossary Entry: Retrievable Stent


Definition: A retrievable stent is a medical device used in interventional radiology and minimally invasive procedures. It is specifically designed to be inserted into a blood vessel or duct to maintain its patency and can be removed or repositioned as needed.

Detailed Description

Types and Variations

Variations: Retrievable stents come in various sizes and configurations to suit different anatomical locations and patient needs. Some may also have specific mechanisms for easier retrieval or repositioning.


Common Uses: Retrievable stents are commonly used in cases of vascular or biliary strictures, as well as in the management of obstructions in the ureter or other hollow organs.

Insertion and Placement

Procedure: The insertion and placement of a retrievable stent involve navigating the device through the body’s vascular or ductal system using imaging guidance. The stent is carefully positioned to provide support and maintain the patency of the vessel or duct.

Clinical Considerations

Potential Complications

Risks: Complications associated with retrievable stents may include migration, occlusion, or tissue ingrowth. Careful monitoring and follow-up are necessary to address these potential issues.

Care and Maintenance

Maintenance Requirements: After placement, retrievable stents require regular imaging and assessment to ensure proper positioning and function. If removal is planned, the retrieval process should be carefully planned and executed to minimize potential complications.

Additional Information

Related Devices

Associated Terms: Related devices may include guidewires, catheters, and imaging equipment used in conjunction with retrievable stent procedures.

Innovations and Advancements

Recent Developments: Recent advancements in retrievable stent technology include improved materials and designs to enhance safety and long-term patency in clinical use.

Regulatory and Safety Notes

Regulations: Regulatory considerations for retrievable stents include compliance with medical device regulations and guidelines for safe and effective use in patient care.
