Abstract
Some embodiments of a medical device anchor system include an anchor device, a tether, and an adapter for securing a medical instrument (such as a catheter or the like) in place relative to a skin penetration point using subcutaneous anchors.
Claims20
An anchor device for securing the position of a medical instrument, the anchor device comprising:
- a first external body comprising a proximal end and a distal end;
- one or more anchors that extend distally from the distal end of the first external body, each anchor comprising a flexible tine that is deployable in a subcutaneous region to secure the first external body relative to a penetration point;
- a tether member that extends proximally from the first external body;
- and
- a second external body that is attachable to the tether member at a position proximally spaced away from the proximal end of the first external body, wherein the second external body is configured to releasably couple to a medical instrument.
2 more elements
An anchor device for securing the position of a medical instrument, the anchor device comprising:
- a retainer body comprising a proximal end and a distal end, wherein the retainer body is configured to releasably couple to a first external portion of a medical instrument;
- first and second anchors that extend distally from the distal end of the retainer body, each anchor comprising a flexible tine that is deployable in a subcutaneous region to secure the retainer body relative to a penetration point;
- a tether member configured to extend proximally from the proximal end of the retainer body;
- and
- an adapter that is attachable to the tether at a position proximally spaced a distance away from the retainer body, wherein the adapter is configured to releasably couple to a second external portion of the medical instrument.
2 more elements
A method of using a medical anchor system, the method comprising:
- deploying subcutaneous anchors of a medical anchor system through a skin penetration point that is occupied by a medical instrument, the subcutaneous anchors being deployed in a subcutaneous region along an underside of a skin layer proximate to the skin penetration point, the subcutaneous anchors extending distally from a distal end of a retainer body of the medical anchor system;
- and
- securing a first external portion of the medical instrument to a second body of the medical anchor system, the second body being tethered to the retainer body via a flexible member that extends proximally away from a proximal end of the retainer body.
