US Patent:

7175913, Feb 13, 2007

Filed:

Jan 28, 2003

Appl. No.:

10/352582

Inventors:

John E. O'Gara - Ashland MA, US

Assignee:

Waters Investments Limited - New Castle DE

International Classification:

B32B 1/00

US Classification:

428405, 428402, 428404, 55524, 96101, 96108, 96290

Abstract:

A material for chromatographic separations, processes for its preparation, and separation devices containing the chromatographic material. In particular, porous inorganic/organic hybrid materials are provided with a decreased concentration of surface organic groups. These particles may be surface modified and have enhanced stability at low pH.

International Classification:

B32B 15/02

US Classification:

428405, 428402, 428404, 210656, 502402, 50252718

Abstract:

Novel materials for chromatographic separations, processes for their preparation, and separation devices containing the chromatographic materials. In particular, the novel materials are porous inorganic/organic hybrid monolith materials, which desirably may be surface modified, and which offer more efficient chromatographic separations than that known in the art.

Inventors:

John E. O'Gara - Ashland MA, US

Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN

International Classification:

A61K 9/50
A61K 51/00

US Classification:

424501, 424 111

Abstract:

According to an aspect of the invention, injectable polymeric particles are provided that contain a copolymer that contains a hydroxy-acid-based repeat unit selected from a mono(hydroxy acid) unit and a poly(hydroxy acid) unit, an alkyl-ether-based repeat unit selected from a mono(alkyl ether) unit and a poly(alkyl ether) unit, and an acid-based repeat unit selected from a unit comprising multiple carboxylic acid groups and a derivative thereof. Other aspects of the invention pertain to methods of making such particles. Still other aspects of the invention pertain to injectable compositions that comprise such particles and to methods of treatment that employ such injectable compositions.
