| 20100074953 | Methods for intiating in situ formation of hydrogels - Methods for initiating formation of hydrogels in situ from a gellable composition and an initiator where the initiator is provided as a solid article or is contained in a solution infused to the intended site of formation of the hydrogel. | 03-25-2010 |
Bruktawit T. Asfaw, Atlanta, GA US
| Patent application number | Description | Published |
|---|---|---|
| 20090209658 | Embolic compositions - Embolic compositions comprising macromers having a backbone comprising a polymeric backbone comprising units with a 1,2-diol or 1,3-diol structure, such as polyvinyl alcohol, and pendant chains bearing crosslinkable groups and, optionally, other modifiers. When crosslinked, the macromers form hydrogels having many properties advantageous for use as embolic agents to block and fill lumens and spaces. The embolic compositions can be used as liquid embolic agents and crosslinked in situ or as preformed embolic articles, such as microspheres. | 08-20-2009 |
Bruktawit T. Asfaw, Mableton, GA US
| Patent application number | Description | Published |
|---|---|---|
| 20120009275 | In-situ forming hydrogel wound dressings containing antimicrobial agents - A composition comprising a macromer that can be in situ polymerized into a hydrogel wound dressing directly on a wound and one or more antimicrobial agents intended to achieve bacteriostasis and/or be bacteriocidal. The antimicrobial agent is released upon application and trapped in the hydrogel upon its formation and also released over a period of time into the wound. | 01-12-2012 |
Mark Asfaw, Roanoke, VA US
| Patent application number | Description | Published |
|---|---|---|
| 20120030372 | REDUNDANT ETHERNET CONNECTION SYSTEM AND METHOD - A system includes a first communication network including a first switch and a second switch connected to the first switch, a second communication network including a third switch and fourth switch coupled to the third switch, and a first computing device coupled to the first communications network through a first network interface controller (NIC) and coupled to the second communication network through a second NIC. The first computing device is configured to communicate through the first NIC first communication network until it determines that it is not receiving bridge protocol data units (BPDUs) and then to communicate through the second NIC. | 02-02-2012 |
