Method Of Manufacturing Fibrous Hemostatic Bandages

View page
US Patent:
8257778, Sep 4, 2012
Filed:
Mar 8, 2012
Appl. No.:
13/414949
Inventors:
Gustavo Larsen - Lincoln NE, US
Ruben Spretz - Lincoln NE, US
Assignee:
LNK Chemsolutions, LLC - Lincoln NE
International Classification:
A61F 13/02
US Classification:
427 231, 95280, 424426, 602 56, 264449, 427 21, 427180
Abstract:
A method of manufacturing a sturdy and pliable fibrous hemostatic dressing by making fibers that maximally expose surface area per unit weight of active ingredients as a means for aiding in the clot forming process and as a means of minimizing waste of active ingredients. The method uses a rotating object to spin off a liquid biocompatible fiber precursor, which is added at its center. Fibers formed then deposit on a collector located at a distance from the rotating object creating a fiber layer on the collector. An electrical potential difference is maintained between the rotating disk and the collector. Then, a liquid procoagulation species is introduced at the center of the rotating disk such that it spins off the rotating disk and coats the fibers.

US Patent:
8297959, Oct 30, 2012
Filed:
May 2, 2007
Appl. No.:
11/743560
Inventors:
Gustavo Larsen - Denton NE, US
Ruben Spretz - Lincoln NE, US
David Vu - Lincoln NE, US
Luis Nunez - Chicago IL, US
Assignee:
Terapia Celular, LN, Inc. - Denton NE
International Classification:
B29B 9/10
A61J 3/07
US Classification:
425 5, 425 3, 425 6, 425 7, 425 8, 264 4, 264 41, 264 5, 264 13
Abstract:
Capsules and particles with at least one encapsulated and/or entrapped agent, such as therapeutic agent, imaging agents, and other constituents may be produced by electrohydrodynamic processes. More particularly, the agent encapsulated in a vehicle, capsule, particle, vector, or carrier may maximize treatment and/or imaging of malignant cancers while minimizing the adverse effects of treatment and/or imaging.

Sol-Gel Preparation Of Porous Solids Using Dendrimers

US Patent:
20030012942, Jan 16, 2003
Filed:
May 3, 2002
Appl. No.:
10/138050
Inventors:
Gustavo Larsen - Lincoln NE, US
Edgar Lotero - Lincoln NE, US
Manuel Marquez-Sanchez - Glenview IL, US
Ruben Spretz - Lincoln NE, US
Assignee:
The Board of Regents of the University of Nebraska
International Classification:
B01J023/38
B32B003/26
US Classification:
428/304400, 502/405000, 502/325000
Abstract:
Methods for the sol-gel preparation of porous inorganic solids having highly uniform metal or metal oxide clusters embedded therein are provided. The porous solids are prepared by incorporating a metal ion-dendrimer complex into a gel and thermally decomposing the dendrimer to produce the solid. The invention further provides for novel inorganic solids exhibiting highly uniform porosity with metal or metal oxide clusters embedded therein.

Methods For Making A Multicomponent Hemostatic Dressing

US Patent:
20090181072, Jul 16, 2009
Filed:
Sep 27, 2006
Appl. No.:
12/299842
Inventors:
Gustavo Larsen - Lincoln NE, US
Ruben Spretz - Lincoln NE, US
Assignee:
LNK CHEMSOLUTIONS, LLC - Lincoln NE
International Classification:
A61L 15/00
US Classification:
424445
Abstract:
A method of making a pliable, bioabsorbable hemostatic dressing wherein the dressing is composed of fibers with at least one molecular-scale coating, which upon first contact with blood and due to a large area of contact with blood per unit weight of active ingredients, initiates and accelerates the biochemical blood clotting cascade processes. The steps of the method include dissolving in an organic solvent one or more soluble bioabsorbable polymers and organic or aqueous-organic media of non-protein constituents to create a homogeneous mixture; forming fibers from the homogeneous mixture; adding to the fibers a molecular-scale first coating of one or more proteins of blood clotting species that minimally react with each other; and optionally adding a second coating of one or more proteins of blood clotting species to the fibers that minimally react with each other and that, together with the one or more proteins of blood clotting species in the molecular-scale first coating, induce blood coagulation in the presence of blood. The fibers may optionally have occluded in them or at their surface other chemicals of abiological or biological origin that aid in the blood clotting process.
