1. A method of delivering a catheter device to an internal body site, comprising:

  • advancing an anchor sleeve through a percutaneous opening in a skin layer so that a subcutaneous cuff device arranged along an outer surface of the anchor sleeve is disposed in a subcutaneous region along an underside of the skin layer, the subcutaneous cuff device comprising a biocompatible material that receives tissue ingrowth when disposed in the subcutaneous region along the underside of the skin layer;

    advancing a catheter device though a working channel of the anchor sleeve and toward a targeted body site such that a distal catheter tip is moved relative to the subcutaneous cuff device disposed in the subcutaneous region along the underside of the skin layer, wherein the distance from the subcutaneous cuff device to the distal catheter tip defining a cuff-to-tip distance;

    adjusting the cuff-to-tip distance by moving the catheter device relative to the anchor sleeve while the subcutaneous cuff device is disposed in the subcutaneous region along the underside of the skin layer; and

    releasably affixing the catheter device in the working channel by compressing a cylindrical surface portion of the anchor sleeve upon at least a portion of an outer circumferential surface of the catheter device so that the portion of the outer circumferential surface of catheter device is retained in a fixed relation to the anchor sleeve.
