1. 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 has a direction of winding and when rotated in the direction of winding to unwind wound coiled threads, each unwound thread rotates about a respective unwound thread longitudinal axis, and the tube tool is configured to unwind the unwound threads in rotation along an unwound thread longitudinal axis which is disposed at an angle relative to the longitudinal axis of the stranded tube, and having a plurality of tube tool thread ducts oriented at a duct angle relative to the longitudinal axis for control of the angle.
5. The system of claim 1 , wherein at least one coiled thread of the fastener is coated with a product, and the product is operative to affect one of the corpus and the conduit, alone and in combination.
