Abstract:
A method for delivering an aerosol, especially an aromatic aerosol, comprising the steps of contacting a capillary wick, comprising an EHD comminution site, with a liquid source, whereby at least a portion of the liquid transports to the EHD comminution site; applying a voltage to the liquid within the capillary wick at a location spaced apart from the liquid source and proximate the EHD comminution site; and applying a ground reference at a location external to the EHD comminution site, wherein at least a portion of the liquid EHD comminutes to form a spray having a generally-consistent flowrate and a device therefor.

A method and device are provided for providing sensory cues, signals, or indicators regarding the status of electrohydrodynamically spraying a material, including power-on status of an electrohydrodynamic spray device, active electrohydrodynamic spray status, and material status within the electrohydrodynamic spray device. In particular, audible, tactile, or intermittent visible signals indicate active electrohydrodynamic spraying, audible, tactile, or visible signals indicate power-on status of the electrohydrodynamic spray device, and sensory signals indicate the status of other operationally-related variables, including the rate of electrohydrodynamic spray, time increments, which may be correlated with electrohydrodynamic spray flowrates, and material supply levels.

A non-respirable aerosol, particularly a non-respirable aerosol comprising a biologically-effective amount of a biologically-active agent dissolved, emulsified, or suspended in a highly-aqueous liquid carrier vehicle. The highly-aqueous liquid carrier vehicle comprises about 60 wt % to about 100 wt % water, about 0 wt % to about 40 wt % of a co-solvent, about 0.05 wt % to about 10 wt % of an acceptable surfactant, and about 0 wt % to about 10 wt % of an excipient. The non-respirable aerosol is substantially monodisperse when dispensed from a sprayhead assembly comprising a preferably linear array of a plurality of nozzles and at least one counter electrode adapted to substantially equalize the charge fields of the plurality of nozzles.

International Classification:
A61M 5/315 A61M 5/20 A61M 5/32 A61M 5/19
Abstract:
A therapeutic agent delivery system () includes a housing () and a drive wheel () rotatably carried by the housing. A plunger rod () may be rotatable with the drive wheel relative to the housing from a first rotational configuration to a second rotational configuration. The plunger rod may be translatable relative to the housing from a first translational configuration to a second translational configuration. A plunger restraint () may maintain the plunger rod in the first translational configuration when the plunger rod is disposed in the first rotational configuration. The plunger restraint may permit the plunger rod to translate to the second translational configuration when the plunger rod is disposed in the second rotational configuration. A needle may move from a stowed configuration to a deployed configuration by the plunger rod when the plunger rod moves from the first translational configuration to the second translational configuration.

International Classification:
A61M 5/20
Abstract:
Processes and devices are disclosed for parenteral delivery of therapeutic fluids, in particular high-viscosity therapeutic fluids (e.g., protein therapeutics), by a chemical reaction that generates a gas. The device may include a first actuation chamber containing a first reagent, a second reaction chamber containing a second reagent, and a third therapeutic fluid chamber containing the therapeutic fluid. In a loaded configuration, a plunger separates the first chamber from the second chamber. In a delivery configuration, the plunger allows the first reagent from the first chamber to communicate and react with the second reagent from the second chamber. The generated gas acts upon a plunger to deliver the therapeutic fluid from the third chamber.
