International ClassesA61M 031/00A61M 005/00 A61F 013/00 AbstractThe invention features an implantable device for the automatic delivery of an active ingredient according to an adjustable delivery profile. The device includes a housing; a reservoir operatively connected to the housing and arranged to store a solid composition including the active ingredient; an actuator arranged within the housing to move the solid composition from the reservoir to a transit area, wherein the solid composition exits the housing at the transit area; a controller that acts on the actuator to adjust movement of the solid composition out of the housing according to the adjustable delivery profile; and a power source arranged to provide energy to the actuator and the controller. The solid composition can be an elongate, solid composition comprising a drug, and up to 90% of a carrier, wherein the composition has a cross-section of less than 0.5 mm, and wherein the drug and the carrier are selected and compounded in a proportion such that the drug is immediately released from the carrier upon contact with a liquid.Field of SearchMeans for placing solid treating material in bodyMeans for ejecting solid from holder Solid ejected from body inserted conduit Eject means moved by force applied to trigger associated with pistol grip Solid units successively fed to conduit from supply means (e.g., magazine, etc.) Eject means driven by spring Solid loaded into injector through opening in side wall of plunger housing Injector or aspirator syringe supported only by person during use (e.g., hand held hypodermic syringe, douche tube with forced injection, etc.) Implant or insert | |
