12. A method of coupling a cannula and another device, comprising the steps of:
-
providing a connection member having a wall defining a chamber, said chamber having two generally opposed apertures and containing a flexible material, one of said apertures operably coupled to the device, a channel defined in the flexible material and extending between said apertures; and providing the cannula with a generally spherical end having a larger diameter than the cannula, whereby said spherical end is receivable in the one of said apertures generally opposed to the one of said apertures operable coupled to the device and is movable through the channel to and from a position generally adjacent to the aperture operably coupled to the device.
