Glossary Entry: Photodynamic Therapy Catheter


Definition: A photodynamic therapy catheter is a medical device used to deliver light-based therapy directly to a specific area within the body, often for the treatment of cancer or other medical conditions.

Detailed Description

Types and Variations

Variations: Different designs and sizes of photodynamic therapy catheters may be used for various medical applications, such as esophageal cancer treatment or intravascular photodynamic therapy for cardiovascular diseases.


Common Uses: Photodynamic therapy catheters are commonly used in the treatment of localized cancers, including esophageal cancer, as well as for the management of specific vascular conditions.

Insertion and Placement

Procedure: The insertion and placement of a photodynamic therapy catheter involve careful navigation to the targeted area, followed by the emission of light to activate a photosensitizing agent within the tissue.

Clinical Considerations

Potential Complications

Risks: Potential complications associated with photodynamic therapy catheters may include tissue damage or inflammation at the treatment site, as well as the risk of adverse reactions to photosensitizing agents.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of photodynamic therapy catheters involve following specific cleaning and sterilization protocols to ensure the device’s safe and effective use.

Additional Information

Related Devices

Associated Terms: Other related devices commonly used in conjunction with photodynamic therapy catheters include endoscopes, imaging tools, and light sources for activating the photosensitive agent.

Innovations and Advancements

Recent Developments: Innovations in photodynamic therapy catheter technology have focused on improving light delivery precision and enhancing the compatibility of photosensitizing agents with targeted tissues.

Regulatory and Safety Notes

Regulations: Regulatory considerations for photodynamic therapy catheters include adherence to specific standards for medical device safety and efficacy, as well as compliance with guidelines for the use of photosensitizing agents in clinical settings.
