摘要:
Bioactive liquid formulations are formed of combinations of absorbable, segmented aliphatic polyurethane compositions and liquid polyether for use as vehicles for the controlled release of at least one active agent for the conventional and unconventional treatment of different forms of cancer and the management of at least one type of bacterial, fungal, and viral infection.
摘要:
Hydroswellable, absorbable and non-absorbable, aliphatic, segmented polyurethanes and polyurethane-urea capable of swelling in the biological environment with associated increase in volume of at least 3 percent have more than one type of segments, including those derived from polyethylene glycol and the molecular chains are structurally tailored to allow the use of corresponding formulations and medical devices as carriers for bioactive agents, rheological modifiers of cyanoacrylate-based tissue adhesives, as protective devices for repairing defective or diseased components of articulating joints and their cartilage, and scaffolds for cartilage tissue engineering.

摘要:
Absorbable and non-absorbable cyanoacrylate tissue adhesive/sealant formulations include at least one multipurpose carboxylic, acid-bearing C-succinylated polymeric rheology modifier capable of increasing the viscosity of the liquid formulation, while controlling the anionic polymerization of the cyanoacrylate monomers and increasing the compliance of the cured solid adhesive.
摘要:
Self-setting, absorbable bioactive polycyanoacrylate-based composites include at least one inorganic phosphate salt or a combination of at least one inorganic phosphate salt and calcium silicate in a cyanoacrylate matrix. The composites can be reinforced with single- or multicomponent absorbable, warp-knitted mesh, thus producing a broad range of absorbable, bioactive biomaterials suitable for use not only as preferred absorbable alternatives to the commercial non-absorbable polymethyl methacrylate bone cements, but also for repairing or replacing cranial and maxillofacial bone defects and other complex defects through guided bone regeneration.
摘要:
Self-setting, bioactive, absorbable composites are derived from inorganic phosphate microparticles and a cyanoacrylate matrix of a methoxypropyl cyanoacrylate at a weight to volume ratio of at least 20/80 of microparticles/matrix. The self-setting composites are capable of the controlled release of bone mineralizing ions, antimicrobials, and bone growth promoters. Such composites are useful as bone cements, fillers, and/or substitutes.
