Abstract
A process for enhancing the security of implantable surgical devices secured to bone tissue comprising implanting in bone tissue a surgical device with a biocompatible adhesive and/or sealant selected from the group consisting of: p1 (a) a material made from monomers of the formula: EQU CHR.sup.1 .dbd.CX.sup.1 Y.sup.1 PA1 wherein X.sup.1 and Y.sup.1 are each strong electron withdrawing groups, and R.sup.1 is hydrogen or, provided that X.sup.1 and Y.sup.1 are both cyano groups, a C.sub.1 -C.sub.4 alkyl group; PA1 (b) a semi-crystalline aliphatic poly(ester) of the formula: EQU [--0--R.sup.11 --C(0)--].sub.y, PA1 wherein R.sup.11 is selected from the group consisting of --CR.sup.12 H--, --(CH.sub.2).sub.3 --0--, --CH.sub.2 --CH.sub.2 --O--CH.sub.2 --, CR.sub.12 H--CH.sub.2, --(CH.sub.2).sub.4 --, --(CH.sub.2).sub.z --O--C(O)-- and --(CH.sub.2).sub.z --C(O)--CH.sub.2 --; R.sup.12 is hydrogen or methyl; z is an integer in the range of from 1 to 7 and y is an integer in the range of from about 10 to about 20,000; and PA1 (c) a slurry of water and a calcium containing compounds with the general formula: EQU M.sup.2+.sub.10-n N.sup.1+.sub.2n (WO.sub.4.sup.3-).sub.6 mU.sup.2- PA1 where n i…
