Thanks for the tip, Owen! I have found several references

involving coronary artery bypass grafting to the " ramus intermedius "

(seems to be more common usage in my context than " ramus

medianus " ), and at

http://www.amershamhealth.com/medcyclopaedia/Volume%20V%202/coronary%20artery.as\

p

I found the following:

.. . .

The left coronary artery usually divides into the left anterior

descending (LAD) and circumflex (Cx) arteries (Fig.1). In

about 15% of the population it trifurcates giving rise to a middle

branch, ramus medianus or intermedius.

.. . .

This would indicate that this " intermedius " branch is located between

the LAD and Cx, i.e., *bisecting* them, and (to my mind) adds weight to

the concept that the " bisectriz " or " bissectrice " must refer to what we call

the " ramus intermedius/medianus " in English.

Thanks to all who cogitated on this problem -- GuyP, G, SharonG,

C -- I think we found it (at least, I'm convinced that this " bisectriz "

= " ramus

intermedius " in my context)!
