  • Patent number: 6902543
    Abstract: The invention relates to a syringe-type device for freshly preparing a solution, suspension or dispersion, for example injectable formulations, preferably according to a method for reconstitution in a vacuum. The device is shown in FIG. 1. The invention also relates to a method for packing the fresh preparation of the solution, suspension or dispersion in a cylindrical reservoir that can be used in a single or multi-dose syringe provided for the same. This is a method for packing the preparation inside the cylindrical reservoir, which is closed on one side by an injection plunger whose movement in the reservoir is limited. This method is characterised in that the elements to be packed are introduced into the reservoir from the injection plunger side before the reservoir is closed by said plunger. Said reservoir is a tube or ampule which is closed on the other side in advance.

  • Publication number: 20020111603
    Abstract: A method for implanting or inserting a solid or semisolid formulation containing at least one active principle uses a device comprising one part set inside the body of the patient and which conditions the solid or semisolid form, brings these conditioning action to the deposit site, injects or inserts in this deposit site, and withdraws after injection or insertion, with one part remaining outside and activating the functions of the device. The invention also concerns a sustained-release solid formulation for parenteral administration comprising a homogeneous mixture of an active principle in non-dispersed state and of a biologically compatible and biodegradable excipient, in which the amount of active principle is at least 50% by weight.

  • Patent number: 6349850
    Abstract: A method comprising the following steps: preparing in a vacuum a dry form (18) of an active principle, as well as a liquid (22), and drawing this liquid into the dry form, by the action of the vacuum to obtain an injectable preparation. The device comprises a gastight syringe (19) to condition under vacuum the dry form, a reservoir (12) containing the liquid (22) and a cap (29) forming a connector between the syringe and the liquid reservoir, the injection needle (25) of the syringe being driven into the septum (24) of the cap (29). The invention enables a preparation which is directly injectable by an automatic rehydration step to be obtained; indeed, after activation, the extemporaneous preparation is automatic since the device elements move by themselves under the action of the liquid which is drawn by suction into the volume under vacuum containing the solid formulation (18).
