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.
Claim 3
Dependent Claim 43 words
An endarterectomy surgical instrument according to claim 1 wherein said spatula tip has a curved body and said optics opening, said plurality of fiber optic cables and said at least one fiber optic cable are within said curved body of said spatula tip.
Claim 4
Dependent Claim 119 words
An endarterectomy surgical instrument according to claim 1 wherein: (a) said spatula tip also has at said first end thereof a plurality of liquid openings, and (b) said connector means also are adapted for connection to a liquid source and a liquid discharge reservoir; and further including: (c) third flexible tubular means extending through said spatula tip from said liquid openings in said spatula tip for conducting liquid from a remote end of said third flexible tubular means connected to said connector means to the surgical site through a first of said liquid openings and for conducting liquid through a second of said liquid openings from the surgical site to said remote end of said third flexible tubular means.
Claim 5
Dependent Claim 19 words
An endarterectomy surgical instrument according to claim 3 wherein said third flexible tubular means extend through said flexible sheathing.
Claim 6
Dependent Claim 29 words
An endarterectomy surgical instrument according to claim 1 wherein said spatula tip also has at said first end thereof a laser opening through which a laser beam is emitted.

Claim 8
Dependent Claim 132 words
An endarterectomy surgical instrument comprising: (A) an elongated body having a spatula tip disposed at a first end thereof for use at a surgical site, said spatula tip including: (1) an optics opening, and (2) at least one first fluid opening adapted to be used in combination with a fluid apparatus to deliver fluid to the surgical site; and (B) a fiber optics assembly coupled to said optics opening, said fiber optics assembly including (1) a plurality of fiber optic cables arranged in a substantially circular array to conduct light from a light source to the surgical site through said optics opening; and (2) at least one fiber optic cable disposed within said circular array to conduct an image of the surgical site to an image forming unit through said optics opening.
Claim 9
Dependent Claim 132 words
An endarterectomy surgical instrument comprising: (A) an elongated body having a spatula tip disposed at a first end thereof for use at a surgical site, said spatula tip including: (1) an optics opening, and (2) at least one first fluid opening adapted to be used in combination with a fluid apparatus to deliver fluid to the surgical site; and (B) a fiber optics assembly coupled to said optics opening, said fiber optics assembly including (1) a plurality of fiber optic cables arranged in a substantially circular array to conduct light from a light source to the surgical site through said optics opening; and (2) at least one fiber optic cable disposed within said circular array to conduct an image of the surgical site to an image forming unit through said optics opening.
