Patent ID: 8920380

Claim:
A method of delivering a catheter device to an internal body site, comprising: advancing flexible anchors of a catheter anchor device through a percutaneous opening in a skin layer so that the flexible anchors and a subcutaneous cuff device of the catheter anchor device are disposed in a subcutaneous region along an underside of the skin layer, the subcutaneous cuff device comprising a biocompatible material that is configure to receive tissue ingrowth when disposed in the subcutaneous region along the underside of the skin layer; moving a catheter through the percutaneous opening in the skin layer toward a targeted body site such that a distal tip of the catheter is moved relative to the subcutaneous cuff device disposed in the subcutaneous region along the underside of the skin layer, wherein a distal length of the catheter extending distally from a distal end of the catheter anchor device is greater than a maximum length of the catheter anchor device, wherein the distance from the subcutaneous cuff device to the distal catheter tip defines a cuff-to-tip distance, wherein said moving causes adjustment of the cuff-to-tip distance while the subcutaneous cuff device is disposed in the subcutaneous region along the underside of the skin layer; and releasably securing the catheter to the catheter anchor device after the adjustment of the cuff-to-tip distance.
