Publication number: 20250090718Abstract: Described herein are compositions composed of a radiopaque agent and a cyanoacrylate monomer. These compositions cure in situ when administered to a subject and, thus, have numerous biomedical applications. The presence of the radiopaque agent allows the practitioner to visualize the compositions during and immediately after administration to the subject. The compositions are non-toxic and shelf-stable, and can be sterilized to prevent microbial growth. The compositions can be pre-mixed prior to sale and distribution, reducing the need for special training in their use.Type: ApplicationFiled: December 5, 2024Publication date: March 20, 2025Inventors: David KIM, Laura BASSAM, Stephen HYNES, Kenneth BROADLEY

Patent number: 12234390Abstract: Dual-cure compositions for use in high temperature adhesive applications, and particularly for temporarily adhesively attaching one substrate to another substrate, are provided. These dual-cure adhesives are silicone-based compositions that can be B-staged by exposure UV radiation to provide initial green strength, followed by a C-stage cure to give adhesives that can survive high temperature processes above 200° C., especially above 300° C., yet easy to debond afterwards to allow separation of the top and bottom substrates.Type: GrantFiled: June 5, 2018Date of Patent: February 25, 2025Assignee: Henkel AG & Co. KGaAInventors: Shengqian Kong, Yayun Liu, Wenhua Zhang, Stephen Hynes, John G. Woods, Jiangbo Ouyang, Chunyu Sun, Bahram Issari

Publication number: 20240009341Abstract: The present invention provides a dressing for application onto a wound. The dressing comprises a porous mesh having a wound-facing side coated with an adhesive for adhering the porous mesh to the skin. The porous mesh is also configured for application of a polymerizable adhesive such that after application the polymerized adhesive and the porous mesh together form a barrier covering the wound. The dressing also includes an absorbent patch disposed on the wound-facing side of the porous mesh and arranged to overlie the wound during use.Type: ApplicationFiled: February 10, 2023Publication date: January 11, 2024Applicant: Chemence Medical Inc.Inventors: Stephen Hynes, Deog-il Kim
