Abstract:
1. A device for fluid delivery into an anatomical feature comprising: a penetrating member driver a disposable having a plurality of cavities; a plurality of penetrating members each at least partially contained in said cavities of the cartridge wherein the penetrating members are slidably movable to extend outward from openings on said cartridge to penetrate tissue; wherein each of said penetrating members comprises a needle with a lumen coupled to a collapsible canister containing a material to be injected and the penetrating member collapses the canister to dispose the material in the canister into the tissue, each of a penetrating member configured to be coupled to the penetrating member driver; a penetrating member sensor; a processor coupled to the penetrating member sensor and configured to be coupled to each of a penetrating member; the processor having control instructions for the penetrating member driver, the processor being configured to adjust an application of force to a penetrating member when the penetrating member contacts a target tissue so that the penetrating member of a penetrating member as the penetrating member moves in the first direction toward a target tissue and precisely determine a position or penetration depth of the penetrating member relative to layers of target tissue or skin being penetrated, the application of a launching force to the penetrating member being controlled based on position and speed of the penetrating member to localize an injection with a tissue.
