Regarding Claim 21, Saadat in view of Kucharski teach the features of Claim 19, as described above.
Saadat in view of Kucharski do not explicitly teach wherein the first outer tube has a different color or a different identifying label than the second outer tube.
Fujikura teaches wherein the first outer tube has a different color or a different identifying label than the second outer tube (Fujikura FIG. 3, side tubes 78, 88, 98; Fujikura paragraph [0090], “the tubes 78, 88, 98 may be made different in their…colors”).
It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to combine Fujikura’s coloring with the method taught by Saadat in view of Kucharski. A person having ordinary skill in the art would be motivated to combine these prior art elements according to known methods to yield the predictable result of a method that allows the side tubes to be readily identified so that their connectors are proper for connecting to an external resource/device (see Fujikura paragraph [0090]).
Response to Arguments
In the December 3, 2025 Pre-Appeal Brief Conference Request, Applicant asserts that Saadat et al. (US PGPUB 2005/0234294 – “Saadat”) fails to teach or suggest the features in Claim 19 of:
transitioning the one or more outer tubes to the expanded configuration includes separately pushing one or more control wires distally to separately extend each of one or more movable supports distally, and
extending each of the one or more movable supports distally pushes the distal portion of one or more corresponding outer tubes of the plurality of outer tubes away from the periphery of the inner tube to the expanded configuration.
The rejection of Claim 19 was based on Saadat. However, the rejection had a typographical error, in which Saadat FIG. 3B, instead of Saadat FIG. 3C, was cited for teaching wherein extending each of the one or more movable supports distally pushes the distal portion of one or more corresponding outer tubes of the plurality of outer tubes away from the periphery of the inner tube to the expanded configuration.
The present non-final Office Action corrects this typographical error.
