The Stockert epShuttle RF ablation generator is widely used for cardiac electrosurgery.  It also incorporates a bioimpedance monitoring circuit. 

Unfortunately, there is no published information on the serial protocol of the data  that emerges from the Stockert Global Port.  Using the device in research, where the ablation parameters are required data, means that you must decode the protocol. 

The bioimpedance circuit operates in real-time, but the values it provides are not accessible unless the enterprising engineer decodes the (possibly serial but definitely non-RS232) communication between the Remote Control Port and the Remote Station.  This protocol is even more arcane than the ablation data protocol.

Over the past few years I have had the necessity to capture both the ablation data and the bioimpedance data.  The ablation data was captured using conventional decode techniques. 

The bioimpedance data was captured using Optical Character Recognition (OCR) of the 7-segment display at the front of Stockert, using a custom OCR optical head made by me.  This was done because a copper link would present an isolation risk.

I provide these solutions without warranty of any kind, for educational purposes only. 

Note that it is your responsibility to maintain patient isolation if you connect any device to Stockert.

This is not negotiable.  If you don't know how to maintain patient isolation then you should seek professional help in the matter.

This is a Xojo 2013r3.1 project, and can run on Mac, Linux, or PC.

The bioimpedance data project is more complex, and it will take me some time to write up.  If you are interested, drop me a line and I'll see what I can do.
