The DiamAbrasion System is a system for removing portions of the outer layers of skin comprising a source of vacuum; abrasive tipped tools; a tube with an internal lumen connecting the vacuum source and the center of the abrasive tipped tools whereby the vacuum functions to clean the skin of exfoliated cells and collect them for disposal to an inline filter. In response to detecting that a potentially disruptive POTS condition is to about to occur, downstream DSL traffic can be temporarily stopped. At one location, the stretch-resisting member is coupled to the primary coil via a flexible anchor assembly disposed within the lumen. In this way, both ease of insertion into the body lumen and anchoring to the lumen is promoted.
