Every year, greater than 200 million catheters are used worldwide to deal with vascular illnesses, together with coronary heart illness and artery stenosis. When navigating into blood vessels, friction between the catheter and the vessel wall may cause main problems.
With a brand new revolutionary catheter expertise, Mostafa Atalla and colleagues can change the friction from having grip to fully slippery with the flick of a swap. Their design improves the protection and effectivity of endovascular procedures. The findings have been revealed in IEEE Transactions on Medical Robotics and Bionics.
Catheter with variable friction
The prototype of the brand new catheter options superior friction management modules to exactly management the friction between the catheter and the vessel wall. The friction is modulated through ultrasonic vibrations, which overpressure the skinny fluid layer. This revolutionary variable friction expertise makes it attainable to change between low friction for easy navigation by means of the vessel and excessive friction for optimum stability through the process.
In a proof-of-concept, Atalla and his staff present that the prototype considerably reduces friction, averaging 60% on inflexible surfaces and 11% on tender surfaces. Experiments on animal aortic tissue verify the promising outcomes of this expertise and its potential for medical functions.
The researchers examined the prototype throughout friction experiments on completely different tissue sorts. They’re additionally investigating how the expertise will be utilized to different procedures, resembling bowel interventions.
