Methods of using atherectomy catheter with deflectable distal tip

An atherectomy catheter has a special tip that can move sideways, allowing it to align with the main body of the catheter. When the tip is moved, it reveals a rotating blade that cuts tissue and creates space for the removed tissue to be stored inside the catheter. This design helps to remove plaque from arteries more effectively, making it easier to place stents afterward. The catheter can be operated in different ways, either by pushing or pulling to cut the tissue. Overall, this new system aims to improve the safety and efficiency of treating blocked arteries compared to older devices.
