Publication number: 20150148752Abstract: A process for lyophilizing a solution of an active agent in a container is provided. Solution of active agent is deposited into a container, the container is covered with a covering plate and placed inside a lyophilizing apparatus. Lyophilization can be conducted to dryness by radiation, convection or both. Also provided is a device made by this process, an active agent-plastic administration device (e.g., a syringe), containing an active agent in the form of lyophilized cake, and an array of such administration devices.Type: ApplicationFiled: January 6, 2015Publication date: May 28, 2015Inventors: Cody L.

Patent number: 6626870Abstract: A syringe assembly is provided which includes a hollow barrel that has an interior wall. The interior wall defines a chamber that retains medication. The hollow barrel also includes a distal end and a proximal end. The distal end of the hollow barrel has a passageway that is in contact with the chamber. The proximal end of the hollow barrel has an aperture. The syringe assembly also includes a primary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The primary plunger tip has a receptor to engage an engager of an elongated tip plunger rod. The syringe assembly also includes a secondary plunger tip that is slidably positioned, in fluid tight engagement, with the interior wall. The secondary plunger tip also has a receptor to engage an engager of a tip plunger rod. The secondary plunger tip is disposed between the primary plunger tip and the proximal end of the hollow barrel.Type: GrantFiled: March 27, 2000Date of Patent: September 30, 2003Assignee: Artix Laboratories, Inc.Inventors: Cody L Yarborough, Michael R.

Patent number: 6610252Abstract: The present invention provides a system for lyophilization comprising one or more delivery containers, e.g. syringes, and a cover plate, which covers them during lyophilization. The cover plate includes a lid region and one or more protuberances, which project perpendicularly from the lid region and fit delivery containers such that the protuberances are not in complete and continuous contact with sidewalls of the delivery containers. The cover plate permits the escape of vapor from the delivery containers during lyophilization process through an annular gap between each protuberance and a sidewall of each container when the cover plate is resting on the top of the delivery containers. At the same the cover plate prevents the escape of lyophilizate, in particular a pharmaceutical, from the containers during lyophilization.Type: GrantFiled: January 22, 2002Date of Patent: August 26, 2003Assignee: Atrix Laboratories, Inc.Inventors: Dominic G. Madril, Cody L Yarborough, Rajan Bawa, Christopher J. Barrett

Patent number: 6566144Abstract: The present invention provides a cover plate that covers one or more delivery containers (e.g., syringe) during lyophilization. The cover plate includes a lid region and one or more protuberances which project perpendicularly from the lid region. The one or more protuberances are adapted to fit in the one or more delivery containers. The cover plate permits the escape of vapor from the one or more delivery containers during the lyophilization process. In addition, the cover plate prevents the escape of lyophilizate from the one or more delivery containers during the lyophilization process. The present invention also provides a system for lyophilizing a solution that contains a pharmaceutical. The system includes one or more delivery containers. The one or more delivery containers contains the solution that contains the pharmaceutical. The system also includes a cover plate used to cover the one or more delivery containers during the lyophilization.Type: GrantFiled: March 27, 2000Date of Patent: May 20, 2003Assignee: Atrix LaboratoriesInventors: Dominic G.
