  • Publication number: 20120294759
    Abstract: Sterilization of medical devices can be performed by stacking packages containing the medical devices. The packages are arranged in a partially-overlapping orientation which is at an oblique angle to the direction of irradiation. The partially-overlapping orientation and oblique angle are predetermined for high sterilization throughput and tight control of irradiation. Instead arranging the packages directly on a sterilization platform at a sterilization facility, the packages can be stacked in the partially-overlapping orientation into a transport container at a location remote from the sterilization facility. The transport container maintains the orientation of the packages. Thereafter, the transport container is placed on the sterilization platform, which results in greater uniformity in radiation exposure while maintaining a high level of sterilization throughput.

The nonaqueous, single-phase vehicle includes at least one solvent and at least one polymer and is formulated to exhibit phase separation upon contact with an aqueous environment. The at least one solvent may be selected from the group consisting of benzyl benzoate, decanol, ethyl hexyl lactate, and mixtures thereof and the at least one polymer may be selected from the group consisting of a polyester, pyrrolidone, ester of an unsaturated alcohol, ether of an unsaturated alcohol, polyoxyethylenepolyoxypropylene block copolymer, and mixtures thereof. In one embodiment, the at least one solvent is benzyl benzoate and the at least one polymer is polyvinylpyrrolidone. A stable, nonaqueous suspension formulation that includes the nonaqueous, single-phase vehicle and an active agent, and a method of forming the same, are also disclosed.

  • Publication number: 20110166554
    Abstract: 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.

  • Publication number: 20050124941
    Abstract: 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.
