The present invention generally pertains to a system and methods for delivering aerosolized substance to a natural orifice of the body.
Blow-Fill-Seal (BFS) technology is a manufacturing technique used to produce small (0.1 ml) and large (and up to 500 ml) liquid-filled containers. The basic concept of blow-fill-seal and form-fill-seal (referred to interchangeably hereinafter as BFS) is that a container is formed, filled and sealed in a continuous process without human intervention in a sterile or aseptic enclosed area. Thus, this technology can be used to sterile or aseptically packaging and manufacturing of pharmaceutical liquid dosage forms. Furthermore, this can be applied to any drug container (produced by any production methods) with a laminate at the bottom thereof, which can be pierced (or break) so as to deliver the medicament.
There are several ways of manufacturing. According to one method, the processes begun as pharmaceutical grade plastic resin is vertically heat-extruded through a circular throat to form a hanging tube (parison). This extruded tube is then enclosed within a two-part mold and the tube is cut above the mold. The mold is zone, or a sterile filling space, where filling needles (mandrels) are lowered and used to inflate the plastic to form a container within the mold. Following formation of the container, the mandrel is used to fill the container with the liquid. Following filling, the mandrels are retracted and a secondary top mold seals the container. All actions take place within the sterile enclosed area, a sterile shrouded chamber within the machine. The product can then be discharged to a non-sterile area for labeling, packaging and distribution.
BFS technology reduces personnel intervention, making it a more robust method for aseptic preparation of sterile pharmaceuticals. BFS is used for the filling of vials for parenteral preparations and infusion, eye drops, and inhalation products. Generally, the containers are made of polyethylene and polypropylene or any plastic resin.
It is therefore a long felt need to provide a system which provides an efficient delivery of a substance to a target site from such BFS containers, provides sufficient material to the target site, and ensures reproducibility.

In all of the embodiments of the device shown hereinbelow, identical numbers refer to identical functions. All figures shown herein are illustrative and none is to scale.
The present invention teaches a device for delivering a predetermined amount of a substance, preferably comprising a medication or combination of medications, into a body orifice of a subject, the orifice comprising any of the body's natural orifices, including a nostril, the mouth, the ear, the throat, the urethra, the eye, the vagina, the rectum and any combination thereof.
In preferred embodiments of the device, the device comprises a delivery mechanism and a medicament capsule, as described hereinbelow. The device can apply a broad range of drugs and materials to the nasal cavity for local effect, deliver a broad range of drugs and materials through the nasal cavity to the systemic circulation, deliver a broad range of drugs and materials through the nasal cavity to the central nerve system (CNS) the brain, spinal cord and associated nerves, and any combination thereof.
The drugs to be applied could be, but are not limited to, pharmaceuticals, natural compounds, biologics, hormones, peptides, proteins, viruses, cells, stem cells and any combination thereof.
However, it should be emphasized that the device can be provided alone as well as in combination with a capsule.
In some cases, the capsule would be provided with a known medicament within the same and in other cases the capsule would be ‘filled’ with the medicament just before use.
In some embodiments of the present invention, the device operating characteristics and the substance characteristics can be jointly optimized to maximize uptake of the substance at the desired site. In preferred variants of such embodiments, uptake is further optimized by exploiting synergies between delivery characteristics generated by the device and by the formulation or composition of the delivered material
In some embodiments, the substance comprises one or more agents to optimize delivery through the mucosal membrane by means of mucoadhesive agent and/or a permeability enhancer agent and/or a particulate formulation in the nano-particle or macro-particle range, and any combination thereof. In such embodiments, the combination of the device and substance enhance the delivery of the active agent to the target area (nasal epithelium and more specifically olfactory epithelium) and from there to the target tissue (for example the brain).
A non-limiting example is a composition comprising a drug to be delivered and at least one chemical permeation enhancer (CPE). In a preferred embodiment, the composition contains two or more CPEs which, by using a nasal delivery device, affect in an additive manner or behave synergistically to increase the permeability of the epithelium, while providing an acceptably low level of cytotoxicity to the cells. The concentration of the one or more CPEs is selected to provide the greatest amount of overall potential (OP). Additionally, the CPEs are selected based on the treatment. CPEs that behave primarily by transcellular transport are preferred for delivering drugs into epithelial cells. CPEs that behave primarily by paracellular transport are preferred for delivering drugs through epithelial cells. Also provided herein are mucoadhesive agents that enable the extension of the exposure period of the target tissue/mucus membrane to the active agent, for the enhancement of delivery of the active agent to and through the mucus membrane.
In contrast to prior-art nasal delivery devices and technologies, the devices of the present invention can produce a fine aerosol in the nasal cavity or other desired body orifice at the target area and at the location of the target tissue instead of producing the aerosol only within the device or immediately after exit from the device. Utilizing the pressure as a driving force and the air as a carrier allows the material to be released from the nozzle as a mixture of aerosol and a pre-aerosolized state. The properties of the resultant aerosol are typically dependent on the properties of the device and of the medium into which the device is discharged. The properties of the device which affect the aerosol characteristics are the delivery pressure, the volume of the delivery gas, the characteristics of its orifice and time of activate.
In some embodiments, the aerosol properties are fairly independent of the delivered substance, while, in other embodiments, the pressure, volume, orifice characteristics, and delivered substance properties can be co-optimized.
In prior-art devices the aerosol is produced in proximity exit of the device. Typically, the aerosol comprises a wide “fan” of aerosol and a low driving force. Therefore, large droplets typically deposit very close to the exit from the device, while smaller droplets tend to quickly contact the walls of the passage, so that deposition is typically predominantly close to the delivery end of the device, with little of the substance reaching desired sites deeper in the body orifice, such as the middle and superior turbinates of the nose. In the present invention the aerosol created, due to the pressurized air carrier, reaches the upper regions of the nasal cavity.

It is well in the scope of the invention wherein the pressurized fluid is accommodated within container for a respectively long time, e.g., by having a pre-pressurized container (step 1A) in a fluid connection (step 2A) with the BFS and releasing the same (step 3A), or alternatively a container suitable to pressuring the fluid in situ within the container, e.g., by introducing a pump or piston mechanism that pressuring ambient air to the container in a first step (step 1B) and accommodating the pressurized fluid along a relatively short time of step 2B, then free the fluid to flow in step 3B.
By the device disclosed herein, the pre-aerosolized mixture of gas and substance exits the device with a significant driving force as a mixture of aerosol and pre-aerosolized material (fluid or powder). When the pre-aerosolized material hits the walls of the nasal passages, it “explodes” into a fine aerosol that is capable of being driven by the pressure deep into the nasal passages to deposit in the desired region.

According to this embodiment, once the device is activated (the pressurized gas container 3 is pressed against the handle), needle 5 pierces the pressurized gas container 3 and the pressurized gas exits therefrom and enters the medicament container to entrain the medicament into the nasal cavity.
Needle 5 is a hollow needle such that when the same pierces the gas container, the pressurized gas exit the pressurized gas container 3 throughout needle 5.
Needle 5 comprises two ends, one of which is a flat, non-sharp end, in fluid communication with the medicament container (will be disclosed hereinafter) and the second one has a sharp end, adapted to pierce the gas container. The two ends interconnected by means of a hollow tube. Once the gas container is pierced the pressurized gas exits therefrom through the hollow tube.

According to this embodiment, at least one spherical element, preferably ball 13, is disposed within the medicament capsule 12. According to another embodiment, at least two spherical elements, preferably ball 13, are disposed within the medicament capsule 12, such that the medicament are disposed between the two balls 13.
The spherical elements are adapted to both (a) seal the medicament capsule 12 and prevent leakage of medicament therefrom; and, (b) once the pressurized air exits the pressurized gas container, the bottom most special element 13 is removed from its position (thereby removing the sealing thereof and enabling the pressurized gas to enter therein) and mixes/compress the medicament enclosed between the two spherical elements 13. Once, the first (bottom most) spherical element is removed, the same compress the medicament disposed between the first and second spherical elements 13 and cases the removal of the second (upper most) spherical element 13. Thereafter, the medicament along with the pressurized gas are delivered to the nasal cavity.

According to this embodiment, the capsule comprises the spherical element 13 being displaced in the bottom most part of the capsule (providing sealing in the bottom part) and a breakable membrane 20 in the upper part thereof (providing sealing in the upper part).
It should be noted that different embodiments of the capsule are available. Reference is now made to
The hole or slot (101A) in the plunger (101) is narrow enough to prevent substance leakage during storage, and wide enough to allow compressed gas passage during activation, wiping the substance from the container during activation. The hole or slot (101A) in the plunger (101) can be designed in many ways to allow delivery that is very efficient, having a residual volume of less than 15% of the original volume. The plunger (101) can be made either from a flexible materials such as, but not limited to, silicone, rubber, flexible plastic or from a hard material such as, but not limited to, a polymer such as Delrin®, a plastic, nylon, metal and any combination thereof.
Ball-type barriers (102) are useful when mixing of several components should occur only upon delivery, when one or more substance should be maintained at low humidity, when the viscosity of the substance varies significantly, and any combination thereof. In addition, contact between the ball (102) and the walls of the capsule (10) can also ensure effective release of the substance from the capsule (10). Examples of substances which tend to cling to walls include, but are not limited to, oils and some powders. The barriers can be balls, as in the embodiment shown, angular dividers or any other shape which can be easily moved by the released compressed gas (low-friction contacts), and still provide effective sealing between the elements to avoid mixing during, for example, shipment and storage.
In a preferred embodiment, each drug containers (103) is made of a soft thin sheet. The sheet can be a polymeric membrane, a continuous sheet or any other form which is thin enough to be easily torn when desired by the released of the compressed air. All drug containers (103) are connected to each other during manufacturing. Mixing occurs only during activation, with the compressed gas tearing the membranes/sheets dividing the compartments. Once the membranes are torn, the substance s are exposed to the compressed gas, mixed and delivered.
This embodiment differs from the previous one in that: (a) the drug containers do not form one unit; (b) the separate zones are separated from each other by membrane which is composed of two layers: one provides the rigidity of the membrane and is made of a rigid material, and the other one is a continuous flexible sheet which seals against the lower rigid part during until activation and which opens when air is pressed against its lower side The membranes (104A, 104B) open only one way, when air presses against their lower side during activation, allowing mixing of the substances during delivery.
These exemplary embodiments allow holding the substances separate during storage and mixing the substances only upon activation and delivery. In some embodiments, the device or the substances therein can be configured to generate a temperature change, either heating or cooling, during mixing and delivery. The device can further be configured so that components for creating a temperature change in the device are not released with the delivered substances.
Heating and cooling can be triggered by mechanical force, by pressure, by chemical reaction and any combination thereof. This can be done inside the drug capsule, around the drug capsule, or outside the device itself in its packaging, to be triggered right before activation of the device.
Such temperature change can be generated during activation (short time temperature change) or prior to activation (long time temperature change). Long time temperature changes require a temperature activation separated from the delivery activation.
Either option, or at least the long time temperature change, further requires proper device sealing to allow temperature to be maintained inside the device and to allow equilibration prior delivery. Such options can further include a temperature indicator, such as by a color change in a dedicated control window, to allow the user to know that the device is ready for activation.
A temperature change can be an increase in temperature, a decrease of temperature, or both.
A temperature change can be useful for example for:
One embodiment comprises two heating agents. These heating agents are in compartments of a capsule. Upon activation of the device, or upon activation of heating (for example, buy pressing a button), a membrane separating the two compartments is torn, allowing the heating agents to mix and to generate heat within the device. Other membranes are not torn by this activity, which keeps the heating agents in a sealed compartment—sealed so as to prevent delivery of heating agent delivery but allow gas passage to other compartments. Passage of the compressed gas then delivers the heated substances or other desired substances. Mixing, as disclosed above, can occur during delivery.

The mixing balls need not be spherical; any shape that will provide good sealing during storage and low-friction movement during activation can be used.

Numerical reference 13S illustrates a stoper element that ensures the hollow piercing element 11 is not piercing the medicament container before activation.
Once the pressurized gas exits from the orifices 13A, it enters the hollow tube of the hollow piercing element 11 and exits thereof from orifice 11H in the sharp end 11P into the medicament container in the nosepiece 4. The pathway of the pressurized air is illustrated by numerical reference 17.
According to this embodiment, illustrated in
As described above, after the pressurized gas container has been pressed, the hollow piercing element 11 has pierced the nosepiece 4, and the bottom end of the hollow piercing element 11 is moved from it position, such that the sealing of the orifices 13M of the pressurized gas container 13 is removed and the release of said pressurized gas from the pressurized gas container 13 is enabled through orifices 13A.
Once the pressurized gas exits from the orifices 13A, it enters the hollow tube of the hollow piercing element 11 and exits thereof from orifice 11H in the sharp end 11P into the medicament container in the nosepiece 4. Such pressurized gas removes the bottom most spherical element 18 from its position to compress the medicament until the pressure reaches the upper most spherical element to remove it from its position. Once the two spherical elements are removed, the medicament and the pressurized gas are mixed and delivered to the nasal cavity.

Once the pressurized gas exits from the orifices 13A, it enters the hollow tube of the hollow piercing element 11 and exits thereof from orifice 11H in the sharp end 11P into the medicament container in the nosepiece 4 to remove the spherical element/s. The pathway of the pressurized air is illustrated by numerical reference 17.

It should be noted that should the capsule enclose several spherical elements 47 the same can be used as divider to enclose several liquid medicaments, several powder medicaments or any combination of both liquid and powder medicaments. It is further noted that the spherical elements 47 can be replaced with a membrane adapted to divide the capsule to several ‘compartments’.
It should further be noted that the hollow extension 35 can be used to remove the sealing of the capsule (in this case, the spherical element) or to pierce the capsule.
Reference is now made to
Once the pressurized gas container 33 is actuated (i.e., pressed), the hollow extension 35 is pushed towards the nosepiece. Such movement results in: (a) piercing of the capsule within the nosepiece 4 by means of the sharp end of the hollow extension 35; or removing the sealing element, which is, in this case, the spherical element; and, (b) the hollow extension 35 moves through the septum 36 and its cover 37 (those are static in the device and cannot move), and thus the orifice 35H is being exposed (uncovered) to enable a fluid communication between the pressurized gas container 33 and the capsule. In such a case, where powder or liquid medicament is utilized, the pressurized gas first remove bottom most spherical element 47, which in turn compress the medicament (positioned between the two spherical elements 47) until max. Compression is reached and then the uppermost spherical element 47 is removed, where only then, the medicament and the pressurized gas come in contact, mix and being delivered . . .
