Improved audio-visual display systems are disclosed. A lesson program in audio frequency form recorded on a storage medium provides control data and narrative information. The control information provides data to the system about the particular lesson program, including the visual images which are to be associated with the narrative information. The control data also provides information concerning the responses expected from users of the system, and instructions for alternative steps available which are prescribed in accordance with a users actual responses. The lesson program may be arranged in chapters which include control data and corresponding narrative information. Separate visuals may be provided, with images indexed for selection by the control data.

An improved audio-visual apparatus for projecting visual information segments carried by a transparency holder in an audio-visual cartridge, and for reproducing corresponding narrative and control information recorded on a movable storage medium carried by the cartridge. The apparatus includes an optical projector for projecting a selected one of the visual information segments onto a screen and a first drive mechanism for supporting the holder and selectively driving it to align specified visual segments with the optical projector. A second drive mechanism supporting the storage medium and selectively moving it independently of the holder to permit reproduction of recorded information is provided, and a playback device is mounted in operative relationship with the storage medium to produce signals corresponding to the stored information. Control information reproduced from the storage medium is fed to a microprocessor which is responsive thereto selectively to operate the first and second drive mechanisms while narrative information is fed to a loudspeaker, whereby selected visual displays and accompanying corresponding audible narrative are produced in predetermined sequences. Manual control selectors is also provided to permit operator response to and modification of the audio-visual program.

The present invention relates to a dilator. The dilator includes a shaft, a lumen and a hub. The shaft has at least two stiffness sections with the stiffness sections becoming less rigid as they approach a distal end of the shaft. The varying stiffness sections allow the dilator to track along the guidewire through torturous vasculature so as the dilator is advanced and the stiffness is changed, the stiffer sheath can advance smoothly through a blood vessel. The dilator may also taper at the distal tip to stretch the initial skin puncture hole larger to accommodate the dilator shaft and ease the sheath tip insertion through to the vasculature. Or the shaft may taper from where it extends beyond the sheath distal tip to the distal end so that it can reach further distal in the vasculature. The dilator may also include an atraumatic tip for easier advancement of the dilator. The dilator distal end may also include one or more radiopaque markers and a shaped distal end.
