A catheter assembly (110, 210) comprising a catheter (130, 230) and a receptacle (120, 220) is disclosed. The receptacle is arranged to accommodate at least part of said catheter and having at least one opening (123) for withdrawal of said catheter. Further, the receptacle is provided with an antimicrobial compound (301) at least in the vicinity of the opening and at least on the outer surface of the receptacle, said antimicrobial compound inhibiting microbes from being transferred to said catheter while being withdrawn through said at least one opening.

1. An intermittent and single use catheter assembly comprising a catheter and a receptacle, said receptacle forming a package for the catheter for maintenance of the catheter in a clean and sterile condition prior to use and accommodating at least part of said catheter and having at least one opening for withdrawal of said catheter, wherein said package-forming receptacle is provided with an antimicrobial compound at least in the vicinity of said one opening and at least on the outer surface of the receptacle, said antimicrobial compound inhibiting microbes from being transferred to said catheter while being withdrawn through said at least one opening. 2. The catheter assembly according to claim 1, further comprising a wetting fluid. 3. The catheter assembly according to claim 1, wherein said catheter has on at least part of its surface a hydrophilic surface layer providing low-friction surface character of the device by treatment with a wetting fluid. 4. The catheter assembly according to claim 3, wherein said wetting fluid is arranged in wetting contact with said hydrophilic surface layer of said catheter in said package-forming receptacle, for preservation of said hydrophilic surface layer in a wetted state during accommodation in said receptacle and provision of a ready-to-use catheter assembly. 5. The catheter assembly according to claim 3, wherein said catheter assembly presents a storage state in which said wetting fluid is kept separated from said hydrophilic surface layer of said catheter, and an activation state in which said wetting fluid is brought into contact with said hydrophilic surface layer before an intended use of said catheter. 6. The catheter assembly according to claim 1, wherein said package-forming receptacle forms a urine collection bag. 7. The catheter assembly according to claim 1, wherein at least a part of said package-forming receptacle forms an elongate pocket of length sufficient to accommodate at least the insertable length of said catheter. 8. The catheter assembly according to claim 7, wherein said at least one opening is arranged on said elongate pocket. 9. The catheter assembly according to claim 8, wherein said package-forming receptacle has at least two openings positioned such that an intermediate part of said elongate pocket may be used as an insertion aid for guiding and holding the wetted catheter during insertion into the human cavity, for instance the urethra. 10. The catheter assembly according to claim 1, wherein said at least one opening is a tear opening. 11. The catheter assembly according to claim 1, wherein said package-forming receptacle is formed of a flexible plastics material. 12. The catheter assembly according to claim 1, wherein said antimicrobial compound constitutes a layer on the outer surface of said package-forming receptacle material. 13. The catheter assembly according to claim 1, wherein said antimicrobial compound is incorporated in said package-forming receptacle material. 14. The catheter assembly according to claim 13, wherein the amount of said antimicrobial compound in said package-forming receptacle material is in the range 0.1 to 20 phr (parts per hundred resin), and preferably in the range 0.5 to 7.5 phr, and most preferably about 4.5 phr. 15. The catheter assembly according to claim 1, wherein said antimicrobial compound is an organic acid metal salt. 16. The catheter assembly according to claim 15, wherein said organic acid metal salt comprises phosphoric acid esters and zinc metal. 17. The catheter assembly according to claim 1, wherein said antimicrobial compound is one of silver nitrate, silver acetate and silver lactate. 18. A method of manufacturing a an intermittent and single use catheter assembly comprising a catheter and a receptacle said receptacle forming a package for the catheter for maintenance of the catheter in a clean and sterile condition prior to use, comprising the steps of: accommodating at least part of said catheter in said package-forming receptacle,providing said package-forming receptacle with at least one opening for withdrawal of said catheter, andproviding said package-forming receptacle with an antimicrobial compound at least in the vicinity of said one opening and at least on the outer surface of the receptacle, said antimicrobial compound inhibiting microbes from being transferred to said catheter during withdrawal through said at least one opening. 19. The method according to claim 18, further comprising the step of: providing said catheter, on at least part of its surface, with a hydrophilic surface layer providing low-friction surface character of the device by treatment with a wetting fluid. 20. The method according to claim 19, further comprising the step of: arranging said wetting fluid in wetting contact with said hydrophilic surface layer of said catheter in said package-forming receptacle, for preservation of said hydrophilic surface layer in a wetted state during accommodation in said receptacle and provision of a ready-to-use catheter assembly. 21. The method according to claim 19, further comprising the step of: arranging said catheter assembly such that it presents a storage state in which said wetting fluid is kept separated from said hydrophilic surface layer of said catheter, and an activation state in which said wetting fluid is brought into contact with said hydrophilic surface layer before an intended use of said catheter. 22. The method according to claim 18, wherein the step of accommodating at least part of said catheter in said package-forming receptacle, at least a part of said package-forming receptacle forms an elongate pocket of length sufficient to accommodate at least the insertable length of said catheter. 23. The method according to claim 22, wherein the step of providing said package-forming receptacle with said at least one opening for withdrawal of said catheter, said at least one opening is arranged on said elongate pocket. 24. The method according to claim 23, wherein said at least one opening comprises at least two openings positioned such that an intermediate part of said elongate pocket may be used as an insertion aid for guiding and holding the wetted catheter during insertion into the urethra.
