I did "Interventional Endourology" sales for Bard a couple years ago. It was Kidney & Stone management and also covered what was left of the women's health division.
Compensation is competitive with others in the market -- it's pretty low base salary and then high commission.
Your call points are going to be urologists and then the rest of the necessary hospital staff -- CoN, Material Manager etc.
There was a choice of a few different cars - Taurus, Escape etc. These were around the $28-30k price point.
It's a tough job. Your main item are stents followed by guide wires and stone baskets and laser lithotripsy fiber wires. If you're not on GPO/contract with the hospital, you can pretty much forget about getting your product in the door. If you are on contract, then your job is to convince the Urologist or hospital to stock and use your stent in all their procedures instead of your competitors.
Main competitors are Boston Scientific (market leader) and Cook (usually the cheap guy).
You're not "on-call" at all hours of the night, however if you have convinced a hospital to do an evaluation on your product, you better be at every procedure they do to make sure it goes smoothly.
You will spend a lot of time in the OR standing over the shoulder of the Urologist, staring into the deep dark hole of an 85 year old man or woman. You'll spend the rest of your time setting up appointments and trying to get into a physicians office during their normal hours.
