20080281271 | DRUG DELIVERY SYSTEM WITH A SMALL AMOUNT OF A THERAPEUTIC AGENT - A drug delivery system includes an automatic injector that can deliver a small, precise amount of a therapeutic agent. The automatic injector includes a chamber for containing a liquid component and a thin porous member that carries thereon and/or therein the small, precise amount of therapeutic agent. Upon activation of the automatic injector, a flow path opens from the chamber through the porous member, enabling the liquid component to rapidly mix with the therapeutic agent before being injected. | 11-13-2008 |
20090270804 | AUTOMATIC INJECTOR WITH NEEDLE COVER - An auto-injector automatically dispenses a predetermined dose of medicament upon activation. The auto-injector includes a needle cover operative to engage an injection site and activate the injector. The needle cover is configured to move from a locked retracted position prior to a medicament dispensing operation to a locked extended position after the medicament dispensing operation. The non-removable needle cover prevents contact with the needle both before and after the medicament dispensing operation. | 10-29-2009 |
20100137808 | Cartridge For Auto-Injector Apparatus - A cartridge assembly apparatus for an auto-injector includes a flexible container containing a liquid medicant. A needle hub is connected to the flexible container. A needle is attached to the needle hub and extends proximally from the needle hub. A frame is connected to the needle hub and includes a frame proximal end extending proximally beyond a proximal end of the needle. The needle hub and the needle are displaceable relative to the frame in a proximal direction to insert the needle into a patient. | 06-03-2010 |
20100137832 | Auto-Injector Apparatus - An auto-injector apparatus includes a flexible container containing a liquid medicant, a needle communicated with a container, a housing with a container being received in the housing, a pump disposed in the housing and positioned to engage the flexible container and expel the medicant from the container through the needle upon relative movement between the pump and the container, and a main drive spring operably associated with the needle to extend the needle from a first needle position wherein the needle is completely received in the housing to a second needle position wherein the needle protrudes from the housing. The pump may be a roller. | 06-03-2010 |
20100228190 | SEAL STRUCTURES FOR WET/DRY AUTOMATIC INJECTORS - An automatic medicament injector has a first compartment for a first medicament component and a second compartment for a second medicament component. The two compartments are separated by a seal structure that converts from a sealing condition to a mixing condition when the device is activated. The seal structure has a plug that opens a flow path through the seal structure to allow the second medicament component to mix with the first medicament component in the first compartment when the seal structure is in the mixing condition. | 09-09-2010 |
20100292643 | Autoinjector With Needle Depth Adapter - An autoinjector useful for, inter alia, providing an injection of liquid medicament is uniquely capable of providing injections, utilizes a needle depth adapter to provide injection depths with a combination of accuracy and precision not heretofore seen. In addition, the autoinjector with needle depth adapter can include a variety of size needle depth adapters to provide an autoinjector of varying, precise injection depths and which can be readily and easily manufactured. The autoinjector includes a housing, cartridge assembly, needle, needle depth adapter, and power providing assembly. | 11-18-2010 |
20100318037 | AUTOMATIC INJECTOR - An automatic injector dispenses a predetermined dose of medicament without a user having to manually force the needle into an injection site. The automatic injector includes a needle cover having a locked retracted position with respect to the injector housing prior to a medicament dispensing operation. The needle cover is operative to engage an injection site prior to a medicament dispensing operation. | 12-16-2010 |
20120046609 | AUTOMATIC INJECTOR - An auto-injector automatically dispenses a predetermined dose of medicament upon activation. The auto-injector includes a needle cover operative to engage an injection site and activate the injector. The needle cover is configured to move from a locked retracted position prior to a medicament dispensing operation to a locked extended position after the medicament dispensing operation. The non-removable needle cover prevents contact with the needle both before and after the medicament dispensing operation. | 02-23-2012 |
20120220930 | Seal Structures For Wet/Dry Automatic Injectors - An automatic injection device including a housing, a chamber with a first compartment and a second compartment, and a seal structure between the compartments. The seal structure is initially in a sealing condition that seals the first compartment from the second compartment, where the seal includes a plug and an outer sealing member. The plug is slidably movable within the outer sealing member to convert the seal structure from the sealing condition to a mixing condition by opening a path between the first compartment and the second compartment. The automatic injection device also includes a needle assembly and an activation assembly. Activation of the activation assembly causes (1) pressurization of the first compartment, (2) the seal structure to convert from the sealing condition to the mixing condition, and (3) the first and second medicament components to be mixed and forced through the needle assembly. | 08-30-2012 |
20130324933 | Cartridge for Auto-Injector Apparatus - A cartridge assembly apparatus for an auto-injector includes a flexible container containing a liquid medicant. A needle hub is connected to the flexible container. A needle is attached to the needle hub and extends proximally from the needle hub. A frame is connected to the needle hub and includes a frame proximal end extending proximally beyond a proximal end of the needle. The needle hub and the needle are displaceable relative to the frame in a proximal direction to insert the needle into a patient. | 12-05-2013 |
20140171871 | Auto-Injector Apparatus - An auto-injector apparatus includes a flexible container containing a liquid medicant, a needle communicated with a container, a housing with a container being received in the housing, a pump disposed in the housing and positioned to engage the flexible container and expel the medicant from the container through the needle upon relative movement between the pump and the container, and a main drive spring operably associated with the needle to extend the needle from a first needle position wherein the needle is completely received in the housing to a second needle position wherein the needle protrudes from the housing.
