12. The deployment device as defined in claim 2, including a fixture on said medical device mounting structure, said fixture designed to at least partially inhibit axial movement of said medical device on said medical device mounting structure as said cover is removed from said medical device.

13. The deployment device as defined in claim 5, including a fixture on said medical device mounting structure, said fixture designed to at least partially inhibit axial movement of said medical device on said medical device mounting structure as said cover is removed from said medical device.

14. The deployment device as defined in claim 6, including a fixture on said medical device mounting structure, said fixture designed to at least partially inhibit axial movement of said medical device on said medical device mounting structure as said cover is removed from said medical device.

15. The deployment device as defined in claim 7, including a fixture on said medical device mounting structure, said fixture designed to at least partially inhibit axial movement of said medical device on said medical device mounting structure as said cover is removed from said medical device.

16. The deployment device as defined in claim 9, including a fixture on said medical device mounting structure, said fixture designed to at least partially inhibit axial movement of said medical device on said medical device mounting structure as said cover is removed from said medical device.

17. The deployment device as defined in claim 12, wherein said fixture has a height that is at least 25% of a maximum space between an outer surface of said medical device mounting structure and an inner surface of said cover when that is formed when said medical device mounting structure is at least partially telescopically inserted in said cavity of said cover.

18. The deployment device as defined in claim 16, wherein said fixture has a height that is at least 25% of a maximum space between an outer surface of said medical device mounting structure and an inner surface of said cover when that is formed when said medical device mounting structure is at least partially telescopically inserted in said cavity of said cover.
