10. A system operable for anchoring of and into at least one corpus disposed distally in a conduit, the system including a handling and manipulation shaft and a stranded tube having a plurality of wound coiled threads and a longitudinal axis, the system comprising: a tube tool associated with the stranded tube and navigated together therewith by the handling and manipulation shaft into engagement with the corpus, the tube tool being configured to unwind at least one wound coiled thread out of the plurality of wound threads as an unwound helically coiled thread by relative rotation against the stranded tube, and the unwound helically coiled thread(s) of the stranded tube being configured for anchoring of and into the corpus with rotational corkscrew-like translation and rotation, wherein the stranded tube proximal portion end of the stranded tube is coupled in releasable attachment relative to the handling and manipulation shaft and to the tube tool, which attachment is released by proximal retrieval of the handling and manipulation shaft, the uncoupled and unwound stranded tube is configured as a fastener operative for anchoring the corpus, and wherein a driven ring is fixedly coupled to the proximal end portion of the stranded tube, and the driven ring is operative as a support for an implement.
18. The system of claim 10 , wherein the stranded tube is configured to be navigated toward the corpus in the wound state and is free from operation thereon of external force applied by at least one of the handing and manipulation shaft, and the tube tool or catheter tube tool.
