A pen needle assembly is provided herein for use with a medical injector containing an injector body and a reservoir sealed by a septum encased in the injector body. The pen needle assembly includes a hub and a needle fixed to the hub. The hub is formed to be telescopingly mounted onto a distal end of the injector body using a track that accommodates a guide key. When mounting the hub of the pen needle assembly onto the injector body, a first portion of the track is configured to receive the guide key and to guide the guide key in a straight line across sufficient distance to permit a proximal end of the needle to fully pierce through the septum, without rotation of the needle. A second portion of the track is configured to permit the pen needle assembly to be turned with the proximal end of the needle being located proximally of the septum.

A pen needle assembly is provided herein having a hub with a distal end and a proximal end; a needle fixed to the hub and having a distal end, for insertion into a patient, and a proximal end; an inner shield disposed proximally of the hub; a spring disposed between the inner shield and the hub and configured to bias the hub distally; an outer shield with a distal end, a proximal end, and a tubular body at least partially encircling a portion of the needle with at least portions located radially outward further from the needle than the inner shield such that the outer shield at least partially encases the hub, the needle, the inner shield, and the spring; and a releasable retaining assembly configured to releasably retain the hub in a first locked state against the biasing of the spring. The distal end of the needle is covered by the outer shield with the hub being in the first locked state. Upon release of the releasable retaining assembly, the hub moves under force of the spring to an unlocked second state.

A cartridge or injector for holding and mixing a medical product is provided herein including a tubular body having a cylindrical wall having first and second opposing ends. The wall includes inner and outer surfaces with the inner surface having a generally constant cross-section along at least a drug mixing area. A first stopper is slidably disposed within the wall between the first and second ends, the first stopper defining a liquid-tight seal with the inner surface. A second stopper is slidably disposed within the wall between the first stopper and the first end, the second stopper defining a liquid-tight seal with the inner surface. A flexible insert is disposed at or in proximity to the second end, the insert forming a liquid-tight seal with the wall, the insert being pierceable by a medical needle or other piercing instrument. A rigid retainer is fixed to the wall having an opening therein for providing access to the insert for piercing by a medical needle. The insert extends into the retainer and forms a liquid-tight seal across the opening.

A safety needle assembly is provided herein which includes a displaceable locking tongue which has a first position in which the locking tongue covers an aperture formed in a shield so as to prevent the passage therethrough of a needle. A biasing element is also provided for urging the locking tongue to the first position. The locking tongue is releasably retained in a retained position prior to use of the safety needle assembly, the aperture being sufficiently uncovered with the locking tongue being in the retained position so as to permit passage of the needle through the aperture. The locking tongue is releasably retained in the retained position against biasing force of the biasing element. With the shield being displaced proximally from a first position to a second position, the locking tongue is released from the retained position and permitted to be displaced to the first position under force of the biasing element. Advantageously, with the subject invention, a safety needle assembly is provided which covers a used needle after use and, optionally, provides a use indicator.

A method for pushing secure notifications includes a push service platform receiving a push notification message request from an entity registered with the push service platform, processing the push notification message request to generate a secure push notification message, and sending the secure push notification message to a target mobile computing device through a native third-party push service associated with the target mobile computing device. The secure push notification message includes a message ID (identifier) that corresponds to message content associated with the push notification message request. The method further includes the push service platform receiving a pull message request from the target mobile computing device, the pull message request requesting the message content associated with the push notification message corresponding to the message ID, and sending the requested message content associated with the push notification message to the mobile computing device.

Disclosed is a population of nanoparticles, together with methods of making a population of nanoparticles, wherein one or more of the nanoparticles includes: an amorphous drug core having an effective diameter less than or equal to about 2.0 microns, wherein the amorphous drug core is substantially free of dopant, and wherein the amorphous drug core comprises a drug with properties that satisfy the following relationships: a glass transition temperature greater than or equal to about 30 Deg. C.; and water solubility at 25 Deg. C. less than or equal to about 1 mg/ml; and at least one stabilizer adsorbed on a surface of the amorphous drug core; and wherein the at least one stabilizer is present in an amount effective to provide an amorphous stability of the population of nanoparticles that is approximately equal to or greater than an amorphous stability of an amorphous bulk drug substance comprising the drug, as measured over a period of at least four months.

A drug delivery device is provided herein which includes a tubular body having a proximal end and a distal end, the tubular body defining an opening at or in proximity to the distal end, the opening defining an inner diameter. A drug cartridge is also provided having a proximal end, a distal end and a barrel portion disposed therebetween. The distal end of the drug cartridge is larger in diameter than the inner diameter of the opening. The drug cartridge is inserted into the tubular body to a use position by first inserting the proximal end of the drug cartridge into the opening. The distal end of the drug cartridge limits insertion of the drug cartridge into the tubular body due to the interengagement of the distal end of the drug cartridge and the tubular body. With the drug cartridge being in the use position, the distal end of the drug cartridge is located at least partially externally of the tubular body. The medical pen injector of the subject invention further includes an adaptor engageable with the body. The adaptor encompasses the distal end of the drug cartridge with the drug cartridge being in the use position. The adaptor includes features for mounting a needle assembly thereto. Advantageously, with the subject invention, a drug cartridge having a large distal end may be accommodated with a drug delivery device, e.g., a pen injector type device.
