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.
Claims19
A catheter anchor device for securing a position of a catheter relative to a percutaneous opening in a skin layer occupied by the catheter, comprising:
- a proximal end, a distal end, and a length extending therebetween;
- a catheter engagement body configured to releasably secure with a catheter;
- a subcutaneous anchor mechanism having first and second flexible anchors that are adjustable to a deployed configuration in which the first and second flexible anchors are configured to abut an underside of the skin layer in a subcutaneous region;
- a subcutaneous cuff device coupled to the catheter engagement body at a location along the catheter engagement body that is distal of the first and second flexible anchors, the subcutaneous cuff device configured to receive ingrowth of bodily tissue when disposed in the subcutaneous region, wherein the subcutaneous cuff device is positioned closer to the distal end of the catheter anchor device than to the proximal end of the catheter anchor device and distal of the first and second flexible anchors;
- and
- an actuator adjustable relative to the subcutaneous cuff device between a first position and a second position to shift the first and second flexible anchors to the deployed configuration and to simultaneously shift a gripper portion to compress an outer surface of the catheter, the first and second flexible anchors retracted within the catheter engagement body when the actuator is in the first position, the first and second flexible anchors located closer to the actuator and the proximal end than to the subcutaneous cuff device when in the deployed configuration.

- and
- an actuator adjustable relative to the subcutaneous cuff device between a first position and a second by sliding longitudinally along a portion of the catheter engagement body between a first position and a second position to shift the first and second flexible anchors to the deployed configuration and to simultaneously shift a gripper portion to compress an outer surface of the catheter, the first and second flexible anchors retracted within the catheter engagement body when the actuator is in the first position, wherein the catheter engagement body includes anchor holes, the first and second flexible anchors extending through the anchor holes in the deployed configuration;
- wherein when in the deployed configuration a distance between the actuator and the first and second flexible anchors is less than a distance between the subcutaneous cuff device and the distal end, the first and second flexible anchors are located closer to the proximal end than to the subcutaneous cuff device, and the first and second flexible anchors located closer to the actuator than to the subcutaneous cuff device.
