Abstract
A wellbore dart can be used to activate a downhole tool within a wellbore to perform a function, such as shifting a sleeve. The dart includes a tool activator that is releasably connected to a body of the dart. After the downhole tool has been activated, the body can be released from the tool activator to open a fluid flow path within the downhole tool. A device can be pumped and land on the tool activator. The tool activator can include multiple sections that expand radially away from each other when force from the device is exerted on the sections. Expansion of the sections allows the device to pass through the tool activator. The dart can also include a retracting device that moves the sections back together after the device has passed through the tool activator.
