Claims26
An in situ formed hydrogel polymer, comprising:
- (a) a first amount of a diamine;
- and
- (b) a second amount of a polyglycidyl ether;
- wherein each of (a) and (b) are present in a mammal or in a medical device located in a mammal in an amount to produce an in situ formed hydrogel polymer that is biocompatible;
- and has a cure time after mixing of from about 10 seconds to about 30 minutes;
