Patent number: 11956282Abstract: Systems and methods for facilitating shared access-right evaluation using linked communication channels are provided. A first communication can be received over a first communication link from a first user device, and a second communication can be received over a second communication link from a second user device. The first and second communications can include requests for the assignment of access rights. Map data can be generated and transmitted to each of the first and second user devices. Each user device can display a visual representation of access-right data. Further, a communication session can be facilitated between the first user device and the second user device. The communication session can be presented on the visual representation for each user device so that the first user and the second user can collaboratively evaluate access rights.Type: GrantFiled: April 12, 2023Date of Patent: April 9, 2024Assignee: Live Nation Entertainment, Inc.Inventors: Dennis A. Denker, Raymond Yung-Chien Lew, Debbie Hsu, Michael Horowitz, Bradford J. Bensen, John Carnahan

Patent number: 11826485Abstract: One aspect of the present invention generally relates to methods of sealing a wound or tissue plane or filling a void splace. In a preferred embodiment, the wound is an ophthalmic, pleural or dural wound. In certain instances, the compositions used to seal the wound or tissue plane comprises a polyalkyleneimine. In a preferred embodiment, the polyalkyleneimine is polyethyleneimine. Treatment of the polyethyleneimine with a cross-linking reagent causes the polyethyleneimine polymers to polymerize forming a seal. In certain instances, the cross-linking reagent is a polyethylene glycol having reactive terminal groups. In certain instances, the reactive terminal groups are activated esters, such as N-hydroxy succinimide ester. In certain instances, the reactive terminal groups are isocyanates. In certain instances, the polyethyleneimine has a lysine, cysteine, isocysteine or other nucleophilic group attached to the periphery of the polymer.Type: GrantFiled: April 23, 2021Date of Patent: November 28, 2023Assignee: HyperBranch Medical Technology, Inc.Inventors: Kenneth E. Stockman, Michael A. Carnahan, Keith R. D'Alessio, Mark W. Grinstaff

Publication number: 20220226179Abstract: Apparatuses and methods for defining an isolation area around an individual. Such an apparatus includes a frame having two opposing and spaced-apart side walls, an interior region within an interior of the apparatus and defined by and between the side walls, and one or more connecting members spanning the interior region and coupling the opposing side walls. Isolation barriers are coupled to the frame and extend outwardly from the interior region. The isolation barriers are configured to define an isolation zone surrounding the interior region that corresponds with the isolation area around an individual located within the interior region. An opening is providing for access by the individual to and from the interior region within the frame.Type: ApplicationFiled: January 18, 2022Publication date: July 21, 2022Inventors: Michael Carnahan, Afshin Zahraee

Publication number: 20040131582Abstract: Novel dendritic polymers are employed to clinically seal or repair wounds and treat traumatized or degenerative tissue. Novel crosslinkable biopolymers such as dendritic macromolecules are used in vitro, in vivo and in situ to treat ophthalmological, orthopaedic, cardiovascular, plastic surgery, pulmonary or urinary wounds or injuries. The crosslinkable dendritic macromolecules can be fabricated into cell scaffold/gel/matrix of specified shapes and sizes using one-photon and multi-photon spectroscopic techniques. The crosslinked polymers can be seeded with cells and used to repair or replace organs, tissues or bones. Alternatively, the polymers and cells can be mixed and injected into the in vivo site and crosslinked in situ for organ, tissue or bone repair or replacement.Type: ApplicationFiled: August 26, 2003Publication date: July 8, 2004Inventors: Mark W.
