Which device requires a 7-8 Fr sheath?

Explanation:
The main idea is that sheath size must accommodate the outer profile of the device being used. The TurboHawk directional atherectomy system has a relatively bulky catheter and cutting head with a sizable lumen to collect debulked plaque, so it requires a larger access sheath to fit safely and allow proper maneuvering and debris management. That’s why a 7- to 8-Fr sheath is specified for this device. Other atherectomy tools may have smaller profiles or different debris handling, so they can often be used with smaller sheaths, which is why they don’t demand the same 7–8 Fr size.
