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; and
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.

Abstract
Some embodiments of a medical device anchor system includes an anchor sleeve and a catheter (or other medical instrument) to advance though a working channel of the anchor sleeve. The anchor sleeve may have a subcutaneous cuff device arranged along an outer surface. In such circumstances, the embedded cuff device can inhibit the migration of infection from outside the skin and into the blood stream.

10. A method of delivering a catheter device to an internal body site, comprising:
-
advancing at least a portion of an anchor device through a percutaneous opening in a skin layer so that a subcutaneous cuff device arranged mounted to the anchor device 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 relative to a lockable portion of the anchor device 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 lockable portion of the anchor device is movable to secure with an outer surface of the catheter device, wherein the distance from the subcutaneous cuff device to the distal catheter tip defining a cuff-to-tip distance; and 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
