Methods and systems for coating a medical device

A medical device coated with a coating, the coating comprising:

• a chemical composition, wherein at least a portion of the chemical composition forms an antimicrobial coating over at least a portion of a surface of a medical device, wherein the chemical composition comprises at least one bridged polycyclic compounds, wherein at least one of the bridged polycyclic compounds comprises a structure:
• wherein each R1 is independently N, N+H, or N+R3;
• wherein each R2 is independently an alkyl group, a substituted alkyl group, or an alkene;
• wherein each R3 is independently an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, a heterocycle group, a substituted heterocycle group, an alkene, a benzyl group, a hydrogen, or a hydrophilic group;
• wherein each R4 is independently an aryl group or a substituted aryl group, wherein when R4 is an aryl group the aryl group is a phenyl, a naphthyl, a biphenyl, a diphenylmethyl, or a benzophenone, wherein when R4 is a substituted aryl group the substituted aryl group is a phenyl having at least one substituent, a naphthyl having at least one substituent, a biphenyl having at least one substituent, a diphenylmethyl having at least one substituent, or a benzophenone having at least one substituent, wherein when R4 is an aryl group at least two moieties forming the aryl group of R4 are independently coupled to the adjacent nitrogen of the —NR3—R2— moiety or the —N+R32—R2 — moiety of the respective structure of the bridged polycyclic compound, or when R4 is a substituted aryl group the substituted aryl group has at least one substituent and at least two moieties forming one or more of the aryl groups of the substituted aryl group are independently coupled to the adjacent nitrogen of the —NR3—R2— moiety or the —N+R32—R2— moiety;
• wherein Z comprises at least one bridge, wherein at least one of the bridges is —R2—N+R32—R4—N+R32—R2—,—R2—NR3—R4—N+R32—R2—,—R2—NR3—R4—NR3—R2—, or R2—N ═R4═N—R2—, and wherein each bridge independently couples R1 to R1;
• and
• wherein X comprises at least one negatively charged counter ion.
