Background
During percutaneous coronary interventions the catheter may stop a coronary blood flow. In order to prevent that complication catheters with side holes are used. However, when a contrast agent is injected part of it exits through the side holes which significantly impairs the visualization of the coronary arteries. To solve this problem we made the new catheter with side valves that close when a contrast agent is injected. After that the side valves open due to pressure in the aorta exceeds the pressure in the catheter and coronary arteries. This catheter can significantly increase the safety and efficiency of percutaneous coronary interventions.
Methods
Based on the catheter with side holes we made the new catheter with side valves for percutaneous coronary interventions. Side valves do not impair movements of coronary guidewires, balloons and stents because made from thin and soft materials but strong enough for secure valve closure.
Results
Catheters with side valves can easily resolve many problems in percutaneous coronary interventions. Guiding catheters and angiographic catheters with side valves can become the main catheters especially in small ostium of left and right coronary arteries, also during catheterization with ostial lesion and in those with ostial vasospasm.
Conclusion
New catheter with side valves for percutaneous coronary interventions can significantly increase the safety and efficiency of percutaneous coronary interventions.
