BOLUS CATHETER FOR THERAPEUTIC AND RADIOLOGICAL INJECTIONS

Examination using contrast media is a medical imaging technique that basically allows the visualization of an anatomical structure. The contrast medium is injected by the venous or arterial route via a vascular catheter, either placed for examination or in place used for the administration of long-term intravenous therapy. The proposed invention has two objectives: to reduce or eliminate the whipping effect and to improve the quality of the bolus at the catheter outlet. Removing the whipping effect improves the reliability and safety of the examination by eliminating inappropriate movement and migration of the catheter. Improving the bolus concentration improves the quality of the exam. This catheter (PICCline, Port line or implantable chamber catheter) of long or very long duration, can be used for any
injection at a lower or higher flow rate during high-flow flushing.

Applications:

• Injection of contrast media for cardiac or radiological exams
• PICCS line and PICCs port suitable
• Suitable with usual catheters, radio catheters and interventional cardiology catheters.
• High flow flushing

Competitive advantages:

• High flow injection
• No unwanted withdrawal effects
• Facilitates the formation of a bolus
