US Patent:

60960183, Aug 1, 2000

Filed:

Aug 3, 1998

Appl. No.:

9/140064

Inventors:

Gary Andrew Luzio - Newark DE
Samuel Anthony Thompson - Wilmington DE

Assignee:

SCIMED Life Systems, Inc. - Maple Grove MN

International Classification:

A61M 3100

US Classification:

604500

Abstract:

The present invention provides a method for medical treatment comprising introducing into a human or animal a medical device selected from the group consisting of stents, catheters, cannulas, plugs and constrictors where the medical device comprises ionically crosslinked polymer. The invention further provides a method for medical treatment of humans and animals comprising introducing into them an ionically crosslinkable polymer and a crosslinking ion followed by crosslinking of the polymer to form a medical device selected from the group consisting of stents, catheters, cannulas, plugs and constrictors.

Appl. No.:

8/128952

Inventors:

Gary A. Luzio - Newark DE
Samuel A. Thompson - Wilmington DE

Assignee:

Hercules Incorporated - Wilmington DE

International Classification:

A61M 532

US Classification:

604265

Abstract:

The present invention provides medical devices comprised of ionically crosslinked polymer, especially, stents, catheter or cannula components, plugs, and constrictors. The medical devices of the present invention are prepared by treatment of ionically crosslinkable polymer compositions with crosslinking ion compositions to provide ionically crosslinked materials. An important aspect of the present invention is that these medical devices can be disintegrated in-vivo at a desired time through the exposure of the medical device to a chemical trigger which generally is described as an agent that acts to displace the crosslinking ion in the ionically crosslinked material through binding or simple replacement with a non-crosslinking ion.

International Classification:

B01D 53/26
B01D 53/02
F24F 3/14

Abstract:

A desiccant member is disclosed that comprises a polymer material and a bentonite material. The desiccant member is capable of absorbing moisture from an atmosphere containing siloxanes, organic compounds having a boiling point greater than 60 C, or mixtures thereof. The desiccant member is contamination resistant and may be regenerable. The desiccant member may have a high working moisture capacity that is suited for demanding environments.
