Filed:

Jun 17, 2003

Appl. No.:

10/463300

Inventors:

Pamela J. Fereira - Santa Clara CA, US
Stephen A. Berry - Hollister CA, US

Assignee:

Alza Corporation - Palo Alto CA

International Classification:

A61F 2/00

US Classification:

424423

Abstract:

The present invention is directed to an osmotic engine useful in an osmotic delivery system for delivery of a beneficial agent in a controlled manner over a preselected administration period. By including a flowable engine comprising at least one osmotic agent and at least one fluid vehicle, the resulting osmotic engine reaches a zero order push power or push rate quickly and provides steady delivery of the beneficial agent.

Assignee:

Intarcia Therapeutics, Inc. - Hayward CA

International Classification:

A61F 13/00

US Classification:

424422

Abstract:

Liquid polyoxaester polymer materials are provided as suspending vehicles suitable for dispensing of pharmaceutically active agents, such as proteins, from delivery devices, for example, pump-driven dosage forms. Polyoxaesters are made from at least one diacid and at least one diol. Through the use of polyoxaesters virtually solvent-free pharmaceutical suspensions can be created.

International Classification:

A61F013/20
A61K009/22

US Classification:

604/018000, 604/892100

Abstract:

An osmotic beneficial agent delivery system includes an implantable osmotic delivery device and a catheter for delivery of the beneficial agent from the delivery device to a delivery location. The beneficial agent delivery system includes a catheter and a docking station which are implanted in the patient with a distal end of the catheter positioned at a delivery site. The catheter and docking station are left in place while an implant containing the beneficial agent is removably connected to the catheter at the docking station and can be replaced as needed. The docking station provides a connection between a catheter and the implant allowing the implant to be replaced periodically while the catheter and the docking station remain in place.

International Classification:

H01P001/20

US Classification:

333/202000, 333/02800R

Abstract:

In a filter assembly having a bandpass filter and a group-delay equalizer coupled thereto by a circulator, there is disposed in the filter and/or the equalizer an electromagnetic wave propagation structure having a cavity with a plurality of tuning elements extending therein. The wave-propagation structure supports a first wave propagating in a first mode and a second wave propagating in a second mode. A first of the tuning elements is positioned to interact with the first wave, a second of the tuning elements is positioned to interact with the second wave, and a third of the tuning elements is positioned for coupling electromagnetic energy between the first wave and the second wave. A fourth of the tuning elements has an orientation perpendicular to an orientation of the third tuning element. Each of the first, the second and the third tuning elements is essentially non-lossy while the fourth tuning element is lossy for obtaining improved flatness of a spectral characteristic of amplitude versus frequency to electromagnetic waves propagating through the filter assembly. A ceramic resonator is located on a central axis of the cavity, and each of the tuning elements is directed toward the central axis. Each of the tuning elements may be constructed as screws for adjustment of depths of penetration of the screws into the cavity for interaction with the electromagnetic waves.

International Classification:

H01P001/208

US Classification:

333/202000, 333/228000, 333/231000

Abstract:

A microwave filter cavity that exhibits spurious mode suppression. The microwave filter comprises a metal mode suppression tuning stub located in a replaceable iris plate that is used to suppress unwanted transverse magnetic (TM) modes of the filter cavity, The mode suppression stub is disposed normal to an end wall of the cavity. The mode suppression stub perturbs the E-field of transverse magnetic modes, while having negligible effect on desired transverse electric (TE) modes. The addition of the tuning stub has no effect on filter performance determined by transverse electric modes.
