Abstract
Some embodiments of a medical device anchor system include an anchor device that receives a medical instrument (such as a catheter or the like) and secures the instrument in place relative to a skin penetration point. In some circumstances, the anchor device may allow the anchor device to be used after medical instrument is already in place without the need for a second penetration point for the anchor device.
Claims15
An anchor system for securing a catheter relative to a skin penetration point, comprising:
- an anchor device including a main body and a retention cap to removably connect with the main body, the anchor device releasably attachable to an outer surface of a catheter when the catheter is occupying the skin penetration point, the retention cap being adjustable relative to the main body between an engaged configuration in which the catheter is frictionally secured to the anchor device and a released configuration in which the catheter is movable relative to the anchor device;
- and
- a first anchor and a second anchor coupled to the main body and extending distally from a distal end of the main body, the first anchor comprising a first subcutaneous flexible tine and the second anchor comprising a second subcutaneous flexible tine, the first subcutaneous flexible tine and the second subcutaneous flexible tine being insertable into a subcutaneous region adjacent to a skin layer to anchor the main body relative to the skin penetration point, wherein the first anchor and the second anchor are insertable through the skin penetration point occupied by the catheter while the main body resides fully external to the skin penetration point, and wherein the first anchor and the second anchor are adjustable from a first configuration to a deployed configuration in which the first and second subcutaneous flexible tines extend outwardly away from one another.
