ThirdCatheter

This App is created by the developer who works on Intervention.

I use this conveniently for daily strategy planning.
The app purchase version saves device information and allows you to "search for information online," "evaluate diameter," "evaluate gap contrast," and "check length."
You will need to enter device information, but you can also share it with friends via AirDrop. Information can also be edited using the CatheterEditor app for Mac.

I would be happy if this app would be useful to people involved in Intervention.
Proceeds will be used to maintain the distribution of other medical apps.
Providing Apps requires an annual fee to Apple. Please understand.
This App calculate the required minimum diameter of a circle inscribing three circles circumscribing each other based on Soddy circles and intuitively displays the relative size of the circle. You can calculate the theoretical minimum diameter of the guiding catheter when using three devices.Please note that the space required for the device to function is not considered.
