Patent ID: 8052746

Claim:
A kit comprising a balloon catheter comprising a balloon at or near its distal end, and a stent mounted on the balloon, wherein the exterior surface of the balloon and stent are provided with a coherent coating comprising a film-forming polymer, the stent is made from a metal tube, and the kit is sterile; wherein the polymer is formed from ethylenically unsaturated monomers including a monomer of formula VIII Y 2 R 30 Q 1 VIII wherein Y 2 is selected from the group consisting of CH 2 ═C(R 23 )—CH 2 —O—, CH 2 ═C(R 23 )—CH 2 OC(O)—, CH 2 ═C(R 23 )OC(O)—, CH 2 ═C(R 23 )—O—, CH 2 ═C(R 23 )CH 2 OC(O)N(R 24 )—, R 25 OOCCR 23 ═CR 23 C(O)—O—, R 23 CH═CHC(O)O—, R 23 CH═C(COOR 25 )CH 2 —C(O)—O—, wherein: R 23 is hydrogen or a C 1 -C 4 alkyl group; R 24 is hydrogen or a C 1 -C 4 alkyl group or R 24 is R 30 Q 1 ; R 25 is hydrogen or a C 1-4 alkyl group; A 7 is —O—or —NR 24 —; and K 2 is selected from the group consisting of —(CH 2) t OC(O)—, —(CH 2 ) t C(O)O—, —(CH 2 ) t OC(O)O—, —(CH 2 ) t NR 28 —, —(CH 2 ) t NR 28 C(O)—, —(CH 2 ) t C(O)NR 28 , —(CH 2 ) t NR 28 C(O)O—, —(CH 2 ) t OC(O)NR 28 —, —(CH 2 ) t NR 28 C(O)NR 28 - (in which the groups R 28 are the same or different), —(CH 2 ) t O—, —(CH) t SO 3 —, and a valence bond t is from 1 to 12; and R 28 is hydrogen or a C 1 -C 4 alkyl group; R 30 is a straight or branched C 2-24 alkanediyl group, or a alkylenoxaalkylene or alkylene(oligo-oxaalkylene) group in which each alkylene has 2 to 12 carbon atoms, and Q 1 is a group Si(OR 26 ) 3 in which the groups R 26 are independently selected from C 1 - 4 alkyl groups.
