Abstract
An endarterectomy surgical instrument and procedure for removing plaque from a selected length of an artery and surgical instruments for cutting plaque build-ups. The endarterectomy surgical instrument has means for developing an image of the surgical site so that probing of the artery can be observed without requiring opening the artery along the selected length over which the plaque is removed.
