摘要： An osmotic delivery system is disclosed for delivering an active agent formulation to a fluid environment. The osmotic delivery system typically comprises a reservoir having a lumen that contains the active agent formulation and an osmotic agent formulation and a piston assembly positioned in the lumen to isolate the active agent formulation from the osmotic agent formulation. The piston assembly typically comprises a body constructed and arranged for positioning in the lumen. The body is typically made of a polymeric material that is, for example, resistant to leaching in an organic solvent. In one embodiment, the body is a columnar body having a rim at a distal end thereof for engaging and sealing against a wall of the reservoir and the piston assembly further comprises a spring retained at the distal end of the columnar body for biasing the rim of the columnar body against the wall of the reservoir.

摘要： Cartridges are provided for storing and facilitating the delivery of pharmaceutical formulations. In one preferred embodiment, the cartridge comprises a body including a bore extending through the body, and a plunger movably disposed in the bore. The bore has a transverse dimension at a distal end that is equivalent to that at a midpoint. The plunger has a planar contact surface that is transversely coextensive with the bore for applying a force to a pharmaceutical formulation contained in the bore. This configuration helps to eliminate dead volume, and therefore enables filing by volume rather than weight to ensure accurate dosing.

摘要： In one aspect, the present invention is directed to an osmotic pump that automatically provides an ascending release rate of active agent as the osmotic pump functions in an environment of operation and may be designed for implantation within a desired animal or human subject. An osmotic pump according to the present invention includes a reservoir, a rate controlling membrane, an expandable osmotic composition, an active agent formulation and an exit orifice. Once administered to an environment of operation, water passes through the rate controlling membrane and into the osmotic composition, which causes the osmotic composition to expand and expel the active agent formulation through the exit orifice at a rate that is directly proportional to the rate at which water passes through the rate controlling membrane. An osmotic pump according to the present invention permits the flow of water through the rate controlling membrane to increase automatically without the need for manipulation of the osmotic pump after administration. As the flow of water through the rate controlling membrane increases, the rate at which active agent is delivered from the osmotic pump will also increase proportionally.

摘要： An osmotic pump having a minimally compliant, volume-efficient piston positioned within a capsule is provided. The capsule has an interior surface, a beneficial agent, and an osmotic agent. The piston is movable with respect to an interior surface of the capsule, and defines a movable seal with the interior surface of the capsule. The movable seal separates the osmotic agent from the beneficial agent. The piston has a length-to-total-diameter ratio of about 1.1:1 and a core-diameter-to-total-diameter ratio of about 0.9:1. The piston enables greater beneficial agent and/or osmotic agent payload without increasing the size of the capsule. The osmotic agent imbibes liquid from a surrounding environment through a semipermeable body to cause the piston to move and, in turn, cause delivery of the beneficial agent from the capsule.

摘要： Osmotic delivery system semipermeable body assemblies that control the delivery rate of a beneficial agent from an osmotic delivery system incorporating one of the semipermeable body assemblies are provided. A semipermeable body assembly or plug includes a semipermeable body which is positionable in an opening of an osmotic delivery system. The semipermeable body has a hollow interior portion having a size selected to obtain a predetermined liquid permeation rate through the semipermeable body. Because the beneficial agent in the osmotic delivery system is delivered at substantially the same rate, the osmotic agent imbibes liquid which has permeated through the plug from a surrounding environment, and the liquid permeation rate through the plug controls the delivery rate of the beneficial agent from the osmotic delivery system. The liquid permeation rate through a semipermeable body may be varied to control the delivery rate of beneficial agent from an osmotic delivery system by changing the thickness of the semipermeable body or by changing an amount of surface area of the semipermeable body that is exposed to liquid when the osmotic delivery system is located in a liquid environment of use.

摘要： The present invention includes devices and methods for reducing the start-up time of osmotically driven drug delivery systems capable of delivering a desired drug at a controlled rate over time. In particular, the present invention includes osmotic pumps that have a preloaded membrane, which includes a semipermeable material that has been preloaded with a nonaqueous, incompressible liquid filler that is miscible with water. The present invention further includes methods for making such osmotic pumps. The preloaded membranes included in the osmotic pumps according to the present invention have proven to provide significant decreases in average start-up times relative to osmotic pumps that include semipermeable membranes that are not preloaded.

摘要： An osmotic delivery system for controlled delivery of a beneficial agent includes an implant capsule containing a beneficial agent and an osmotic agent which swells on contact with water causing the release of the beneficial agent over time. The osmotic delivery system has a membrane plug which allows water to pass through the plug from an exterior of the capsule while preventing the compositions within the capsule from passing out of the capsule. A delivery rate for delivery of the beneficial agent from the implant capsule is controlled by varying a core diameter of the membrane plug within a constant diameter capsule. The membrane plug has a variable water permeation rate depending on an extent to which the membrane plug is constrained by the capsule walls.
