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.
Claims20
A method, 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 configured to receive tissue ingrowth when disposed in the subcutaneous region along the underside of the skin layer, wherein the subcutaneous cuff device is positioned closer to a distal end of the catheter anchor device than to a proximal end of the catheter anchor device and distal of the flexible anchors;
- 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;
- and
- adjusting an actuator of the catheter anchor device relative to the subcutaneous cuff device between (i) a first position in which the flexible anchors are deployed to anchor the catheter anchor device in the subcutaneous region and (ii) a second position in which the flexible anchors are undeployed and retracted into the catheter anchor device, the flexible anchors located closer to the actuator than to the subcutaneous cuff device when deployed, wherein a distance between the actuator and the subcutaneous cuff device along a longitudinal axis of the catheter anchor device is greater in the first position than in the second position.

A method, comprising:
- advancing a first flexible anchor and a second flexible anchor of a catheter anchor device through a percutaneous opening in a skin layer so that the first and second 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 configured to receive tissue ingrowth when disposed in the subcutaneous region along the underside of the skin layer, wherein the subcutaneous cuff device is positioned closer to a distal end of the catheter anchor device than to a proximal end of the catheter anchor device and distal of the first and second flexible anchors;
- 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;
- and
- adjusting an actuator of the catheter anchor device relative to the subcutaneous cuff device and along a longitudinal axis defined between the distal end and the proximal end of the catheter anchor device, such that the actuator linearly translates between a first position and a second position to shift the first and second flexible anchors to a deployed configuration, wherein the actuator is spaced apart from the first and second flexible anchors along the longitudinal axis in the first position and the second position.
