Novel Use of an Orbital Atherectomy Device for In-Stent Restenosis: Lessons Learned

Figure 2

(a) Picture demonstrating normal orbital atherectomy device composed of coiled wires and sanding disc coiling of supportive wires provide radial strength and flexibility. (b) Picture showing an unused device with the creation of potential spaces caused by mild traction of the device. This space is the likely area on which the stent strut was caught during retraction of the device, thereby facilitating the unwinding process. (c) Picture of the unwound device showing three supportive struts that are no longer coiled.
