well, more info needed:
*load impedance / load current / load resistance
*cable length
*desired rise/fall time of pulses at load.
if rise/fall time can be long compared to round trip delay depending on cable length and type, and load current is small (impedance or resistance large), then it is a quite easy task.
edit:
well, I read the patent short: it is pretty much self explatory what is needed to implement the device
There is a principal schematic drawing showing a implementation.
Today you would not implement it using discrete Transistors and Transformers.
But if you can´t make sense of it (sorry if I´m impolite) you are probably wrong person for the task at Hand
And it is a "medical device" so while I could design an implementation I´m not firm with the special compliance rules for medical equipment.
