A thrombectomy or atherectomy device (10) includes a thrombectomy or atherectomy catheter (12) including a cutter (20), and a physical barrier (22, 24) disposed proximate to the cutter. In some examples, the physical barrier (22, 24) can have a stiffness effective for the physical barrier to deflect a blood vessel having a thickness less than a first predetermined thickness threshold and effective for a thrombus or atheroma on an inner wall of the blood vessel to deflect the physical barrier.

This application relates to a system, method, and apparatus for image-based analysis of plaque. In some embodiments, the methods described herein can be used for developing treatment plans. Treatment plans may include local treatment, systemic treatment, or both. In some embodiments, the approaches described herein can be used for stent selection. In some embodiments, the approaches described herein can be used for surgical planning, including robot-assisted surgical planning. In some embodiments, the approaches described herein can be used for image normalization. In some embodiments, the approaches described herein can be used to identify a threshold for plaque calcification. In some embodiments, the approaches described herein can be used to identify thin-capsule fibrous atheroma. In some embodiments, the approaches described herein can be used for reconstruction of the coronary artery tree. Some embodiments are intended for risk stratification of coronary artery disease.

Provided are a method, a device, and a program for accurately determining the risk of an atheroma. This method for determining the risk of an atheroma includes a condition determination step and a risk determination step. In the condition determination step, it is determined whether or not an atheroma shown in one or more tomographic images of a blood vessel of a patient which have been acquired by an imaging method utilizing optical interference satisfies the following conditions (a) and (b): (a) the atheroma has a fibrous cap having a thickness that is not more than a predetermined threshold value; and (b) the atheroma contains cholesterol crystals. In the risk determination step, when it has been determined that the atheroma satisfies the conditions (a) and (b), it is determined that the atheroma satisfying the conditions (a) and (b) has higher risk compared with an atheroma that satisfies one or neither of the conditions (a) and (b).
