1. StentSaver The “Distal” Device

2. What is it? The Distal Device of the StentSaver is what the doctor controls to operate the Proximal device inside the patient The Distal Device of the StentSaver is what the doctor controls to operate the Proximal device inside the patient The controls the doctor uses are simple: two dials and two sliders The controls the doctor uses are simple: two dials and two sliders

3. Dial1 Slider1 Slider2 Dial2

4. What Do the Controls Do? Dial1 controls the rotational position of the Proximal Device inside the patient Dial1 controls the rotational position of the Proximal Device inside the patient Slider1 controls the in/out position of the Proximal Device’s curved extension Slider1 controls the in/out position of the Proximal Device’s curved extension

5. Controls cont’d Slider2 controls the in/out position of the Proximal Device’s straight extension Slider2 controls the in/out position of the Proximal Device’s straight extension Dial2 controls the deployment of the Proximal Device’s Nitinol ‘Clips Dial2 controls the deployment of the Proximal Device’s Nitinol ‘Clips

6. How Does it Work? Respective tubes are connected to their counterparts inside the Distal Device and extend inside the body Respective tubes are connected to their counterparts inside the Distal Device and extend inside the body A gear transmission system controls the advanced functions related to the clip deployment (see report for details) A gear transmission system controls the advanced functions related to the clip deployment (see report for details)
