Publication number: 20140128476Abstract: An implant having shape forming and hardening functionality is described. The implant is formed from shape memory materials. The implant is formed from a shape memory alloy, shape memory polymer, or combinations thereof, to provide them with the ability to be compressed into a shape that facilitates minimally invasive insertion. Subsequent to such insertion, the shape memory materials provide the implant with the ability to regain its original shape and size. Subsequently, the implant becomes rigid, thereby providing strength, structural integrity and support.Type: ApplicationFiled: November 1, 2013Publication date: May 8, 2014Applicant: Boo Holdings, LLCInventor: Charles S.

Publication number: 20140127320Abstract: A composition and method adapted for delivery of hydrophilic, biologically-active agents are disclosed. The composition can include a reverse microemulsion formed from at least one hydrophilic, biologically-active agent solubilized by a hydrophobic reverse emulsion surfactant in a non-stinging, volatile, hydrophobic solvent. The non-stinging, volatile, hydrophobic solvent is selected from the group consisting of volatile linear and cyclic siloxanes, volatile linear, branched, and cyclic alkanes, volatile fluorocarbons and chlorofluorocarbons, liquid carbon dioxide under pressure, and combinations thereof. The reverse microemulsion can be an optically clear solution.Type: ApplicationFiled: October 21, 2013Publication date: May 8, 2014Applicant: ROCHAL INDUSTRIES, LLPInventors: Joseph Charles Salamone, Xiaoyu Chen, Ann Beal Salamone, Katelyn Elizabeth Reilly

Publication number: 20140127147Abstract: The invention relates to water-soluble or water-swellable polymers the repeating structural units of which consist of a) 90.0 to 99.99 mole-% of one or more repeating structural units originating from special monomers with sulfonic acid groups or the salts thereof such as for example 2-acrylamido-2-methyl-propanesulfonic acid or the salts thereof and b) 0.01 to 10.0 mole-% of one or more repeating structural units originating from special cross-linking agents with at least three polymerizable double bonds. The polymers for example have an advantageous sensory property profile and are highly suitable as thickening agents even in salt-containing compositions. They are furthermore advantageously suitable for producing cosmetic, dermatological or pharmaceutical compositions.Type: ApplicationFiled: March 3, 2012Publication date: May 8, 2014Applicant: CLARIANT FINANCE (BVI) LIMITEDInventors: Peter Klug, Dirk Fischer, Thomas Lindner, Wiebke Mueckenheim, Bianca Brasch, Michael Hornung

Patent number: 8716422Abstract: Materials and Methods for the generation of polyelectrolyte multilayers that can erode to release cationic components. The multilayers comprise layers that contain one or more cations and one or more charge-dynamic anionic polymers. Charge-dynamic anionic polymers contain side chains having removable functional groups. Removal of the functional groups results in a change in the net change in the charge of the polymer which can disrupt interactions between cations and the anionic polymers and facilitate release of cations.Type: GrantFiled: October 23, 2012Date of Patent: May 6, 2014Assignee: Wisconsin Alumni Research FoundationInventors: Xianghui Liu, Jingtao Zhang, David M.
