Plastic Containers Having Inner Pouches And Methods For Making Such Containers

View page
US Patent:
6364864, Apr 2, 2002
Filed:
Jun 3, 1999
Appl. No.:
09/325436
Inventors:
Mahmood Mohiuddin - Hawthorn Woods IL
George D. Cimino - Lafayette CA
Derek J. Hei - Concord CA
Assignee:
Baxter International Inc. - Deerfield IL
International Classification:
A61B 1900
US Classification:
604410, 604408, 604416, 206219
Abstract:
Containers and methods for making containers are disclosed. The containers include a chamber and a pouch fixed within the chamber. During manufacture, the open edges of the pouch are sealed between the walls of the container by a seal defining, in part, the peripheral edge of the chamber.

Methods And Devices For The Removal Of Psoralens From Blood Products

View page
US Patent:
6544727, Apr 8, 2003
Filed:
Jun 7, 1996
Appl. No.:
08/659249
Inventors:
Derek J. Hei - Concord CA
Assignee:
Cerus Corporation - Concord CA
International Classification:
A01N 102
US Classification:
435 2, 4351731, 4351739, 424529, 424530, 424531, 604 501, 604 502, 604 608, 604 609, 604 61, 604 615, 604262, 604403, 604406, 604408, 604409, 604410
Abstract:
Methods and devices for the removal of psoralens and psoralen photoproducts from blood products are described. The methods include contacting a psoralen- and irradiation-treated blood product with a resin capable of adsorbing psoralens and psoralen photoproducts. The removal process is particularly suitable for use with platelet concentrates and plasma because the process does not have a significant adverse effect on clotting factor function. The methods and devices can be incorporated with apheresis systems and other devices and procedures currently used to process blood products for transfusion.

Absorbing Pathogen-Inactivating Compounds With Porous Particles Immobilized In A Matrix

View page
US Patent:
6951713, Oct 4, 2005
Filed:
Dec 10, 2001
Appl. No.:
10/016323
Inventors:
Derek J. Hei - Concord CA, US
Michael S. Clarke - San Francisco CA, US
Assignee:
Cerus Corporation - Concord CA
International Classification:
A01N001/02
A61K035/14
C12N007/06
C12M001/00
C07K001/00
US Classification:
435 2, 424529, 435238, 4352831, 530412, 530413, 530415
Abstract:
Methods and devices are provided for reducing the concentration of low molecular weight compounds in a biological composition, while substantially maintaining a desired biological activity of the biological composition. The device comprises highly porous adsorbent particles, and the adsorbent particles are immobilized by an inert matrix. The matrix containing the particles is contained in a housing, and the particles range in diameter from about 1 μm to about 200 μm. The matrix can be fibrous, and the particles can have a surface area greater than 750 m/g and a pore diameter between about 25 and 800 Å. The device can be used to adsorb and remove a pathogen-inactivating compound that is a nucleic acid-binding compound such as psoralen, an acridine derivative or a dye from a biological composition such as a blood product.

US Patent:
7025877, Apr 11, 2006
Filed:
Jun 3, 1999
Appl. No.:
09/325599
Inventors:
Serge de Gheldere - Hoeilaart, BE
Mahmood Mohiuddin - Hawthorn Woods IL, US
Peyton S. Metzel - Libertyville IL, US
George D. Cimino - Lafayette CA, US
Derek J. Hei - Concord CA, US

Assignee:
Baxter International Inc. - Deerfield IL
Cerus Corporation - Concord CA
International Classification:
B01D 15/00
US Classification:
210202, 2102571, 210266, 210282, 422101
Abstract:
Apparatus, systems and methods are disclosed for treating a biological fluid with light. A container of biological fluid is introduced into a fluid treatment chamber where it is contacted with light provided by one or more light sources in proximity to the fluid treatment chamber. A drawer for holding containers of biological fluid introduces the containers into the chamber. Containers for holding the biological fluid are marked by the apparatus to indicate the status of the treatment.
