Patent application numberDescriptionPublished
20080215034Endotracheal cuff and technique for using the same - An inflatable balloon cuff with a water-swellable coating may be adapted to seal a patient's trachea when associated with an endotracheal tube. The water-swellable coating may enhance a cuff's mechanical pressure seal. The water-swellable coating may be loosely adhered or not adhered to the cuff in order to allow the coating to flow into and seal any leak paths that may form when the cuff is inflated in a patient's trachea.09-04-2008
20080268243Coated filaments - The present disclosure describes a coating for a surgical filament including a vinyl lactam polymer and a lactone polymer.10-30-2008
20090035572YARNS CONTAINING THERMOPLASTIC ELASTOMER COPOLYMER AND POLYOLEFIN FILAMENTS - Braids and surgical devices are made from yarns that include a core sheath construction with at least one yarn made from a thermoplastic elastomer and at least one yarn made from a polyolefin material.02-05-2009
20100069957Coated Filaments - The present disclosure describes a coating for a surgical suture including a vinyl lactam polymer and a lactone polymer.03-18-2010
20100092530Novel Triclosan Salts - Novel silver-triclosan salts are provided which have antimicrobial properties and may be used as pharmaceutical compositions or to treat articles such as medical devices, packaging materials, and textiles.04-15-2010
20100297066BIODEGRADABLE PEPTIDE RELEASING POLYMERS - Novel biodegradable compositions are disclosed. The biodegradable compositions include at least one hydroxyl-terminated component and at least one bioactive peptide in a linear chain. The compositions may be utilized as medical devices including drug delivery devices, tissue adhesives and/or sealants.11-25-2010
20110129512Antimicrobial Releasing Polymers - The present disclosure is directed to polymers having hydroxyl containing bioactive agents incorporated into the backbone of the polymer or attached thereto by pendant linkages. Hydroxyl containing bioactive agents which may be attached to these polymers include antimicrobial agents such as triclosan. The polymers may be utilized to form medical devices or coatings for such devices. The hydroxyl containing bioactive agent may be released from the polymer upon hydrolysis of the polymeric backbone or pendant linkage in vivo.06-02-2011
20110172705Water-Swellable Copolymers and Articles and Coatings Made Therefrom - The present disclosure relates to compositions comprising a copolymer that includes a first monomer and a second monomer that is different from the first monomer, wherein both the first and second monomer are selected from the group consisting of 3-sulfopropyl acrylate potassium salt, sodium acrylate, N-(tris(hydroxyl methyl)methyl)acrylamide, and 2-acrylamide-2-methyl-1-propane sulfonic acid. The present disclosure further relates to methods for preparing the copolymer compositions and shaped articles comprising the copolymers.07-14-2011
20110172707Water-Swellable Copolymers and Articles and Coatings Made Therefrom - The present disclosure relates to compositions comprising a copolymer that includes a first monomer and a second monomer that is different from the first monomer, wherein both the first and second monomer are selected from the group consisting of 3-sulfopropyl acrylate potassium salt, sodium acrylate, N-(tris(hydroxyl methyl)methyl)acrylamide, and 2-acrylamideo-2-methyl-1-propane sulfonic acid. The present disclosure further relates to methods for preparing the copolymer compositions and shaped articles comprising the copolymers.07-14-2011

20090032027Multiple balloon endotracheal tube cuff - An airway ventilation device for insertion in a body cavity is provided. The airway ventilation device includes an endotracheal tube having multiple inflation cuffs. Adjacent inflation cuffs form indentation areas whereby bacterial secretions are removed through various liquid stabilizing means. An individual inflation cuff may optionally exhibit a twist in the opposite directions of an adjacent inflation cuff.02-05-2009

20110201688N,N'-DI-P-BROMOPHENYL GUANIDINE TREATMENT FOR STROKE AT DELAYED TIMEPOINTS - 1,3 di-o-tolylguanidine (DTG) was examined as anti-stroke drug with a broad therapeutic window. DTG activates sigma 1 and 2 receptors. Administration of DTG at 24 hours post-stroke to rats reduces neurodegeneration by 85%; this is the only pharmacological agent that has been used successfully at this delayed timepoint. Treatment with DTG provides protection of neurons exposed to hypoxia and blocks activation of immune cells that are responsible for delayed neurodegeneration associated with stroke. Disclosed is an altered DTG structure, placing a bromide at the para position to increase tissue penetrance and efficacy. Results show that N,N′-di-p-bromophenyl guanidine protects cultured neurons under hypoxic conditions but is more potent than DTG. Moreover, N,N′-di-p-bromophenyl guanidine is as least as efficacious as DTG in treating rats 24 hours after experimental stroke.08-18-2011

20100101163MODULAR ELEMENTS FOR STRUCTURAL REINFORCEMENT - A structural element made of a composite material includes a plurality of modular cells disposed within the composite material that have tensile elements that create axially directed tension anchoring elements attached to the tensile elements that create compression with anchoring elements of proximate modular cells. The modular cells may be disposed randomly or in a patterned manner within the composite material. A stackable structural cell facilitates more efficient creation of beams or columns and can include rebar for some of the tension elements that are axially arranged. Additionally, modular cells and/or supported capsules may be added to increase tension and/or decrease mass or weight of the beam or column. The structural cell can further include a boundary layer for containing the composite material prior to hardening.04-29-2010
