Abstract: Various disclosed embodiments include illustrative apparatuses, systems, and methods for injecting medicant into target tissue. In an illustrative embodiment, an illustrative apparatus includes a distal end, a proximal end configured to engage a delivery catheter, and a plurality of flexible bands that extend from the distal end to the proximal end. The flexible bands exhibit a delivery configuration and a deployed expanded configuration. When the plurality of flexible bands are in the deployed expanded configuration a cavity is formed and a medicant receivable via the delivery catheter is disbursable into the cavity.
