Abstract
Medical and surgical uses for random alkylene oxide copolymers have been discovered. Preferably, this is a biocompatible, non-metabolizable, non-toxic, and/or readily eliminated compound that has a viscosity which is adjustable for different utilities (e.g., from runny oil to thick grease). It is also preferable to formulate the compound as an anhydrous and/or flowable liquid before use or further formulation.
Claims35
A compound for use in medicine or surgery, wherein said compound is a random copolymer comprised of ethylene oxide and one or more other alkylene oxide(s) having (i) molecular mass from 1 kg/mol to 1000 kg/mol and (ii) mass ratio of the ethylene oxide to the other alkylene oxides is from 5:95 to 95:5.
The process according to 20, wherein said composition is used as adhesive, cohesive, filler, lubricant, or any combination thereof for medical or surgical treatment of the subject.
A process of making a product useful for medicine or surgery, which comprises suspending (a) particles in (b) a carrier comprised of ethylene oxide and at least one other alkylene oxide having (i) molecular mass from 1 kg/mol to 1000 kg/mol and (ii) mass ratio of the ethylene oxide to the other alkylene oxide is from 5:95 to 95:5.
