    摘要: This invention relates to electrical devices that are implantable inside an animal, including humans. The invention particularly relates to polyurethane headers mounted on the electrical devices to house electrical contacts. The polyurethane headers are formed by (a) mixing (i) a prepolymer comprising a silicon-containing diol of formula (I) in which R 1 , R 2 , R 3 and R 4 are independently selected from C 1-6 alkyl; R 5 and R 6 are independently selected from C 1-6 alkylene; R 7 is C 1-6 alkylene, O, S or NR in which R is H or C 1-6 alkyl; and n is 1 to 3 and a diisocyanate; and (ii) a C 2-12 alkanediol; (b) injecting the mixture of the prepolymer and the C 2-12 alkanediol into a mould having a cavity shaped to form a header; (c) allowing the mixture to cure and form a polyurethane header within the mould; and (d) releasing the formed polyurethane header from the mould.
