US Patent:

8100868, Jan 24, 2012
Filed:

Oct 29, 2010
Appl. No.:

12/915691
Inventors:

Brian L. Newton - Woonsocket RI, US
Charles F. Ganem - Cape Neddick ME, US
David B. Woyak - Carolina RI, US
Richard T. Boisjoly - Nashua NH, US
Assignee:

Nypro Inc. - Clinton MA
International Classification:

A61M 5/00
US Classification:

604247, 604246, 604256
Abstract:

A gland member within a medical valve is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. To that end, the valve has a housing forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen that is a part of the flow path. The lumen has an opening to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region formed at least in part between the gland member itself and the post member. In addition, the variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume (i. e. , when the valve is in the open mode) that is no less than its closed volume (i. e.

Filed:

Feb 13, 2009
Appl. No.:

12/371185
Inventors:

Richard T. Boisjoly - Nashua NH, US
Assignee:

NYPRO INC. - Clinton MA
International Classification:

A61M 39/22
C10M 101/04
C08K 5/20
C10M 133/16
US Classification:

604256, 508100, 508107, 524230, 508459
Abstract:

A device includes an elastomer component that has a molecular scaffold. The molecular scaffold defines interstitial spaces. The component is impregnated with a vegetable oil carrying a fatty acid amide to impart a lubrication to the component and thereby impart a resistance to adhering to a surface of the component. In an illustrative device, a valve includes an elastomeric member that includes a vegetable oil and a fatty acid amide. A method for manufacturing such a device and a precursor for use in manufacturing are also disclosed.
