Disclosed are applicators and methods injecting of a liquid anesthetic into a dental patient with no or minimal pain. In accordance with one embodiment the applicator is for intraligamentary injection and includes an elongated, thin member having an open distal free formed of a resilient and somewhat conformable material suitable for producing a substantially fluid-tight interface with the anatomic structures at the gingival sulcus to inject the anesthetic therein. In another embodiment the applicator includes a flexible skirt surrounding a sharpened cannula, with the cannula being movable with respect to the skirt. The skirt is arranged to receive the anesthetic to anesthetize the gum, whereupon the cannula can then pierce the gum to inject the anesthetic into the underlying anatomic structure.

The invention relates to trans-epithelial frictionally abrasive tissue sampling devices for performing biopsies and methods of inducing an immune response against a pathogen, wherein epithelial cells containing the pathogen are disrupted with the frictionally abrasive tissue sampling device to introduce the pathogen into the bloodstream of a patient.

A medicament delivery device includes a housing, a medicament container disposed within the housing, an activation mechanism, a cover and an electronic circuit system. The activation mechanism includes an energy storage member configured to produce a force to deliver the dose of a medicament and/or vaccine. The cover is configured to receive at least a portion of the housing. The electronic circuit system is coupled to the housing such that a protrusion of the cover electrically isolates a battery from a portion of the electronic circuit system when the portion of the housing is received by the cover. The electronic circuit system is configured to be electrically coupled to the battery and to produce a recorded speech output when the portion of the housing is at least partially removed from the cover. The electronic circuit system configured to produce a signal when the activation mechanism is actuated.

The present invention provides various medical instruments for delivery of nasal medication. It provides devices for influencing fluid flow around and/or inside a device. It also provides improved drug delivery systems to administer a desired dosage to the nasal epithelia, SPG, or a predetermined area.

In an aspect of the invention, an array of microprotrusions is formed by providing a mold with cavities corresponding to the negative of the microprotrusions, casting atop the mold a first solution comprising a biocompatible material and a solvent, removing the solvent, casting a second solution atop the first cast solution, removing the solvent from the second solution, and demolding the resulting array from the mold. The first solution preferably contains an active ingredient.

Disclosed herein are methods for overfilling primary packaging components, and drug products prepared according to those methods. The methods may include introducing a volume of a formulated drug substance into a primary packaging component having a nominal volume, where the volume of the formulated drug substance is greater than the nominal volume of the primary packaging component. In some cases, the primary packaging component may be a prefillable syringe.

Embodiments of the invention provide multi-stage biodegradable drug delivery platforms and methods for the subcutaneous delivery of therapeutic agents (TA). Embodiments of the platform may be configured to subcutaneously deliver a first dose of a first TA which is absorbed into the body and/or blood stream (BBS) to produce a first therapeutic effect for a first selectable time period (STP), and subsequently after a second STP, deliver a second dose of a second TA which is absorbed into the BBS to produce a second therapeutic effect for a third STP. An embodiment of the platform may comprise a body having a tissue-penetrating end, a primary cavity having a first TA dose and a shell having a secondary cavity having a second TA dose. The first TA dose is released after the first STP and the second TA dose is released after the second STP by biodegradation of the shell.

Module for operational control of the guided advance/withdrawal device of the needle added to the smart substance injection device on board equipment for inoculating substances inside a fertile egg and smart method for injection inside a fertile egg, wherein the inoculation of substances inside a fertile egg, be this into the embryo, in the case of vaccines, and even into the amniotic fluid, in the case of a nutrient or nutritional vaccine complex, allows the injection needle (11) to be brought close at a controlled speed.

A delivery device for and method of delivering substance, in particular a vaccine, to a mucosal surface within the oral cavity of a subject, the device comprising: a mouthpiece unit to be gripped in the mouth of a subject, wherein the mouthpiece unit is configured such that, on exhalation or attempted exhalation by the subject, a pressure is developed in the oral cavity which is such as to close the oropharyngeal velum of the subject; and an oral outlet unit including at least one outlet from which substance is in use delivered to a mucosal surface within the oral cavity of the subject.
