Catheter for Endovascular Brachytherapy

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes an improved catheter specifically designed for use in endovascular brachytherapy, especially for Selective Internal Radiation Therapy (SIRT). The catheter includes one or more radiation detectors and specialized shielding so it can accurately measure radioactive emissions from therapeutic microspheres inside blood vessels. Its unique structure allows for real-time detection of any reflux (undesired backflow) of the radioactive microspheres, thus tracking their distribution and preventing them from entering healthy tissue.

Use CasesContent extracted from patent full text and abstract with AI.

• Monitoring and controlling SIRT procedures for liver cancer and metastases treatment
• Detecting reflux or misplacement of radioactive microspheres during endovascular therapies
• Providing real-time feedback during brachytherapy to minimize risk to healthy tissues
• Enhancing safety and efficiency in the application of radiotherapeutic microspheres in other organs via endovascular routes
• Supporting research and development in targeted endovascular radiotherapy methods

BenefitsContent extracted from patent full text and abstract with AI.

• Enables real-time detection and monitoring of radioactive microsphere placement and possible reflux
• Reduces the risk of damage to healthy tissue by identifying inadvertent backflow and enabling timely intervention
• Improves precision and effectiveness of SIRT and other endovascular brachytherapies
• Allows for detailed mapping of microsphere distribution across vessels, potentially optimizing therapeutic outcomes
• Integrated design allows simultaneous delivery and monitoring, simplifying procedures and potentially reducing operation time and complexity

Patent Abstract

The invention relates to a catheter (1) for measuring endovascular radioactive radiation, having an essentially tubular shape, an inner lumen (2), a proximal end (p) and a distal end (d) end, the catheter (1) having, in the distal area, at least one first detector (3) for measuring radioactive radiation (5, 6) and at least one first shield (4) for shielding against radioactive radiation, the first shield (4) being arranged such that only radioactive radiation can be measured (6) on the outer face of the catheter by the first detector(s).
