摘要:
Propellable apparatus, assemblies and related methods including a self-enclosed member are disclosed. The self-enclosed member can include an inner surface at least partially defining an enclosed region, and an outer surface that turns outwardly to engage a cavity or lumen wall in addition to turning inward to at least partially encompass a central region defining a longitudinal path. The apparatus can include an internal drive mechanism engageable with the outer surface of the self-enclosed member to provide relative movement between the self-enclosed member and the cavity or lumen wall. A tapered member, positioned on the apparatus adjacent an end of the self-enclosed member, can provide a size transition between an outer surface portion of the self-enclosed member and an outer surface of a payload insertable within the central region. In some examples, one or more reinforcing members can be integrated within the self-enclosed member for increased durability and rotational use.
