Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 94 words
An elongated, flexible plastic structure defining a continuous sequence of connected vertebra-like elements useful in endoscopes and the like comprising: an elongated plastic extrusion or injection molding defining a tube having a generally circular wall, said tube having an internal, elongated web structure incorporating a central lumen or bore all coextensive with said tube, a plurality of secondary bores formed in the tube wall and a plurality of cut-outs formed in said wall along the length of the tube effective to make the tube more flexible while preserving the integrity of the central bore.
Claim 2
Dependent Claim 94 words
An elongated, flexible plastic structure defining a continuous sequence of connected vertebra-like elements useful in endoscopes and the like comprising: an elongated plastic extrusion or injection molding defining a tube having a generally circular wall, said tube having an internal, elongated web structure incorporating a central lumen or bore all coextensive with said tube, a plurality of secondary bores formed in the tube wall and a plurality of cut-outs formed in said wall along the length of the tube effective to make the tube more flexible while preserving the integrity of the central bore.
Claim 3
Dependent Claim 13 words
The structure of Claim 1 in which the cut-outs intersect the secondary bores.
Claim 4
Dependent Claim 14 words
The structure of Claim 2 in which the cut-outs are V-shaped in cross-sectional configuration.
Claim 5
Dependent Claim 19 words
The structure of Claim 2 in which the cut-outs are arranged according to a uniform pattern in opposed pairs.
Claim 6
Dependent Claim 18 words
The structure of Claim 1 in which the cut-outs are sealed by a thin- walled elastomeric, membranous sheet.
Claim 7
Dependent Claim 18 words
The structure of Claim 5 in which the sheet defines a sleeve overlaying the exterior of the tube.
Claim 8
Dependent Claim 34 words
The structure of Claim 1 in which the internal web structure defines two intersecting webs dividing the internal cross-sectional area of the tube into four independent sectors or quadrants each coextensive with the tube.
Claim 9
Dependent Claim 63 words
An elongated, flexible plastic structure defining a continuous sequence of connected vertebra-like elements useful in endoscopes and the like comprising: an elongated plastic extrusion or molding defining a tube having a generally circular wall, a plurality of bores formed in the tube wall and a plurality of cut-outs intersecting said wall along the length of the tube to make the tube more flexible.
Claim 10
Dependent Claim 63 words
An elongated, flexible plastic structure defining a continuous sequence of connected vertebra-like elements useful in endoscopes and the like comprising: an elongated plastic extrusion or molding defining a tube having a generally circular wall, a plurality of bores formed in the tube wall and a plurality of cut-outs intersecting said wall along the length of the tube to make the tube more flexible.
