US Patent:

6524305, Feb 25, 2003

Filed:

Jul 24, 1998

Appl. No.:

09/122073

Inventors:

Lewis L. Peterson - Woodside CA
Fred H. Maruyama - San Jose CA
Houdin Dehnad - El Granada CA
Lawton Hom - San Francisco CA
Kevin S. Ly - San Jose CA
Craig R. Davis - Newark CA
John R. Peery - Stanford CA

Assignee:

Alza Corporation - Palo Alto CA

International Classification:

A61K 922

US Classification:

6048921, 424422, 424473

Abstract:

An osmotic delivery system flow modulator assembly, an osmotic delivery system with a flow modulator assembly, and a method of assembling an osmotic delivery system. The osmotic delivery system flow modular assembly includes a body having a hole located through the body and communicating two opposing ends of the body. The use of the osmotic delivery system flow modulator assembly lessens the chance that air or gas pockets will form in the enclosure of the osmotic delivery system during assembly of the system. Because less air is within the osmotic delivery system, performance of the system is enhanced. Use of the flow modulator assembly also lessens the chance that beneficial agent will be wasted during assembly of the osmotic delivery system.

Appl. No.:

10/269004

Inventors:

Syed F A Hossainy - Fremont CA, US
Fuh-Wei Tang - Temecula CA, US
Houdin Dehnad - El Granada CA, US

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61L 33/00
A61K 9/00
A61K 47/32

US Classification:

427 21, 424400, 5147724

Abstract:

A coating for a medical device, particularly for a drug eluting stent, is described. The coating comprises a polymer having a weight-average molecular weight between about 200,000 and about 250,000 Daltons or a polydispersity index between about 2. 6 and about 3.

A61K 9/70
A01N 25/00

US Classification:

424422, 424449, 424423, 514937

Abstract:

This invention relates to stable non-aqueous single phase viscous vehicles and to formulations utilizing such vehicles. The formulations comprise at least one beneficial agent uniformly suspended in the vehicle. The formulation is capable of being stored at temperatures ranging from cold to body temperature for long periods of time. The formulations are capable of being uniformly delivered from drug delivery systems at an exit shear rate of between about 1 to 1×10reciprocal second.
