Atheroscopy is one of the minimally invasive endovascular methods used for peripheral vascular access. Atherectomy (arterial shaving), in other words, is a minimally invasive method of opening arterial stenosis and obstruction with the help of angiography, special catheter (plastic tube) or devices.
As it is done in the support of angiography, the following question may arise; What is the difference between this method and the balloon or stent procedure applied to the peripheral arteries (arteries)? To respond immediately, this method is very different from the balloon or stent method. The method is the method of trimming the artery with the help of an atherectomy device, which is designed and developed for this purpose, which is specifically designed for this purpose, and is called a microcatheter (very thin plastic tubule). As I mentioned, almost all of these devices are micro-catheters (very thin plastic tubular diameter) and are designed to be thin and thin.
Nowadays, different methods are used for atherectomy. Microcatheter method offers many advantages in the treatment process.
The micro-catheter production process is generally less forgiving of errors compared to manufacturing processes of other devices. This mainly depends on the smaller external diameters (OD) and inner diameters (IDs) required by micro-catheters.
Smaller IDs and ODs reduce the overall wall thickness of the device, which makes it difficult to achieve the required pushability, traceability, and torque capability for different applications. Because the wall thickness is determined by application requirements, more components and capabilities required by the micro-catheter increase the minimum OD value. The design and manufacture of an ultra-thin wall micro-catheter meeting the demands of the neurovascular and cardiovascular market is a task that should only be performed by those with expertise and experience in this field.
