Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
236 words
An endarterectomy surgical instrument comprising: (A) a spatula tip having at a first end thereof: (a) an optics opening, and (b) a plurality of fluid openings; (B) first flexible tubular means extending through said spatula tip from said optics opening to a remote ends, said first flexible tubular means including a plurality of fiber optic cables disposed in a substantially circular array to conduct light from a light source, and at least one fiber optic cable disposed within said circular array to conduct an image of the surgical site to an image forming unit (C) second flexible tubular means extending through said spatula tip from said fluid openings in said spatula tip to said remote end (D) connector means connectable to: (a) the light source; (b) the image forming unit, and (c) a fluid source and to which: (a) said remote end of said first flexible tubular means, and (b) said remote end of said second flexible tubular means are connected for conducting: (i) the light from the light source to said first flexible tubular means, (ii) the image of the surgical site from said first flexible tubular means to the image forming unit, and (iii) fluid from the fluid source to said second flexible tubular means; and (E) a flexible sheathing extending between said spatula tip and said connector means and through which said first flexible tubular means and said second flexible tubular means extend.
Claim 2
Dependent Claim
236 words
An endarterectomy surgical instrument comprising: (A) a spatula tip having at a first end thereof: (a) an optics opening, and (b) a plurality of fluid openings; (B) first flexible tubular means extending through said spatula tip from said optics opening to a remote ends, said first flexible tubular means including a plurality of fiber optic cables disposed in a substantially circular array to conduct light from a light source, and at least one fiber optic cable disposed within said circular array to conduct an image of the surgical site to an image forming unit (C) second flexible tubular means extending through said spatula tip from said fluid openings in said spatula tip to said remote end (D) connector means connectable to: (a) the light source; (b) the image forming unit, and (c) a fluid source and to which: (a) said remote end of said first flexible tubular means, and (b) said remote end of said second flexible tubular means are connected for conducting: (i) the light from the light source to said first flexible tubular means, (ii) the image of the surgical site from said first flexible tubular means to the image forming unit, and (iii) fluid from the fluid source to said second flexible tubular means; and (E) a flexible sheathing extending between said spatula tip and said connector means and through which said first flexible tubular means and said second flexible tubular means extend.
