Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
57 words
An instrument for accessing a target area including a blade, the blade comprising: shaft means positionable proximate the target area of a patient, said shaft means having a relatively curved distal section for cooperatingly supporting a distal section of a leaf means thereon and at least one fiber optic image bundle for viewing a target area; and
Claim 2
Dependent Claim
57 words
An instrument for accessing a target area including a blade, the blade comprising: shaft means positionable proximate the target area of a patient, said shaft means having a relatively curved distal section for cooperatingly supporting a distal section of a leaf means thereon and at least one fiber optic image bundle for viewing a target area; and
Claim 3
Dependent Claim
153 words
A laryngoscope comprising: blade means having a shaft means with an image bundle for viewing a target area, a distal end positionable proxmiate the throat region of a patient, and a leaf means interactable with the tongue of a patient, said leaf means having a notch means; and means for removable mounting said leaf means with said shaft means such that said leaf means is positionable proximate said shaft means distal end, said mounting means including a post means fixed to said shaft means cooperatable with said notch means on said leaf means, said notch means comprising a first type of aperture means and a second type of aperture means, said second type of aperture means being relatively tapered from said first type of aperture means for providing a scabbard fit between said second type of aperture means and said post means whereby said leaf means can be removed from said shaft means.
Claim 4
Dependent Claim
153 words
A laryngoscope comprising: blade means having a shaft means with an image bundle for viewing a target area, a distal end positionable proxmiate the throat region of a patient, and a leaf means interactable with the tongue of a patient, said leaf means having a notch means; and means for removable mounting said leaf means with said shaft means such that said leaf means is positionable proximate said shaft means distal end, said mounting means including a post means fixed to said shaft means cooperatable with said notch means on said leaf means, said notch means comprising a first type of aperture means and a second type of aperture means, said second type of aperture means being relatively tapered from said first type of aperture means for providing a scabbard fit between said second type of aperture means and said post means whereby said leaf means can be removed from said shaft means.
Claim 5
Dependent Claim
24 words
A laryngoscope as in claim 2 wherein said first type of aperture means has a first size for insertion of said post means therein.
Claim 6
Dependent Claim
15 words
A laryngoscope as in claim 2 wherein said leaf means comprises a relatively curved section.
Claim 7
Dependent Claim
18 words
A laryngoscope as in claim 2 wherein said leaf means comprises a first side having a textured surface.
Claim 8
Dependent Claim
23 words
A laryngoscope as in claim 2 wherein said leaf means comprises a relatively wide section for interaction with the tongue of a patient.
Claim 9
Dependent Claim
25 words
A laryngoscope as in claim 2 wherein said leaf means is movable relative to said shaft means between a first position and a second position.
Claim 10
Dependent Claim
21 words
A laryngoscope as in claim 7 wherein said second position comprises said leaf means being relatively fixed with said shaft means.
Claim 11
Independent Claim
121 words
A method of manufacturing a laryngoscope comprising the steps of: providing an elongate shaft means being positionable proximate a throat region of a patient, said shaft means having a relatively curved distal section; inserting an image bundle into a channel in said shaft means; fixing a post means on one side of said shaft means; providing a leaf means having a slot means cooperatable with said post means on said shaft means, said slot means having tapered bayonet aperture means for making a scabbard fit with said post means, said leaf means further including a relatively curved distal section for cooperation with said shaft means distal section whereby said leaf means can be connected to and removed from said shaft means.
