Abstract
A transcutaneous access tool includes a first cannula moveable along an axis, a fixed member including an elongated prong extending parallel with the axis, and a deployment member secured to the first cannula and movable along the axis away from the fixed member. The deployment member includes spaced-apart, resiliently flexible fingers extending parallel with the axis and having distal ends that are laterally enlarged with respect to the axis. The resiliently flexible fingers are received on the prong of the fixed member. A second cannula is disposed within the lumen of the first cannula, and retraction member is secured to the second cannula and is movable along the axis. The retraction member includes at least one catch catching on the laterally enlarged distal ends of the fingers of the deployment element when the fingers are laterally held apart by the prong of the fixed member.
