Spot coagulating & occluding instrument and method of use
First Claim
1. A spot coagulating and occluding apparatus, comprising:
- an elongated tubular member extending along a central longitudinal axis to define a lumen and having a distal end and a proximal end disposed opposite the distal end;
a pair of occluding fingers projecting generally longitudinally from the distal end of the tubular member in a facially-opposing relationship, each one of the pair of occluding fingers terminating in an occluding end effector with the occluding end effectors being movable relative to one another to and between an opened state wherein the occluding end effectors are spaced apart from one another and a closed state wherein the occluding end effectors are one of adjacent to and in contact with one another;
a central channel running through said tubular member between the pair of occluding fingers and opening outward between said end effectors;
whereby a proximal end of the tubular member is operative in conjunction with the occluding fingers to move the occluding end effectors to and between the opened and closed states.

Abstract
A spot-occlusion apparatus spot-coagulates or otherwise occludes an anatomical tissue structure which is disposed in a living body and has a plurality of vessels extending therefrom. The occlusion apparatus includes an elongated tubular member and an occluding mechanism. The tubular member extends along a central longitudinal axis to define a lumen and has a distal end positioned interiorly of the living body and a proximal end disposed opposite the distal end and positioned exteriorly of the living body. The occluding mechanism is operative at the distal end of the tubular member and includes a pair of articulating fingers with distal end effectors (such as occluding elements) disposed opposite one another. The pair of end effectors are moveable to and between an opened state and a closed state. In the opened state, the vessels to be occluded are received between the pair of occluding end effectors. In the closed state, the pair of occluding end effectors contact and occlude the vessels, thereby occluding the anatomical tissue structure. The articulating fingers create a working space between themselves for manipulating, coagulating and/or otherwise occluding tissue. Moreover, one or more ports is directed through the lumen into the workspace for admission of a viewing system, hydration device, cauterization device, cryo (cooling) device, suction, or any of a range of ancillary surgical implements all through a single surgical site.

15. A surgical instrument, comprising:
-
an elongated tubular member extending along a central longitudinal axis to define a lumen and having a distal end and a proximal end disposed opposite the distal end;
a pair of bent fingers projecting generally longitudinally from the distal end of the tubular member, each finger bending around to an end effector, and the fingers being movable relative to one another to and between an opened state wherein the end effectors are spaced apart from one another and a closed state wherein the end effectors are together and the bent fingers define a surgical workspace therebetween;
a central channel running through said tubular member between the pair of occluding fingers and opening outward between said end effectors;
an actuating handle disposed at the proximal end of the tubular member and operative to manually move the end effectors to and between the opened and closed states. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A spot coagulating and occluding apparatus, comprising:
-
a tubular member extending along a central longitudinal axis to define a lumen and having a distal end and a proximal end disposed opposite the distal end;
a pair of occluding fingers projecting from the distal end of the tubular member, flaring outward, and converging together in an opposing relationship, each one of the pair of occluding fingers terminating in an occluding end effector with the occluding end effectors being movable relative to one another to and between an opened state wherein the occluding end effectors are spaced apart from one another and a closed state wherein the fingers flare outward from said tubular member to straddle healthy tissue and then converge together into contact with one another in order for said end effectors to operatively occlude targeted tissue;
whereby a proximal end of the tubular member is operative in conjunction with the occluding fingers to move the occluding end effectors to and between the opened and closed states. - View Dependent Claims (24, 25)
