Healey, you posted the images on Thursday. I saw them but could not reply because I was in Vanderbilt Cardiology waiting for the doctors to decide what to do about the angina that I was experiencing. On Saturday, they finally decided to put a stent in one of the vein sections that had been used for my quadruple bypass surgery 20 years ago. The surgeon fed the stent in through an artery in my wrist to my heart. I was fully awake for this one; no local anesthesia was required.
It did hurt when the surgeon sliced my wrist open to locate the deep Radial Artery. I heard him say, "It's not there, on to plan B."
He made another slice and said, "There it is."
It hurt again as he jammed the catheter into the vein. From then on... no more pain.
I watched the monitor as they injected dye and located the blockage.
Then I watched as a balloon was inflated to open the artery.
And then... the stent was installed by blowing it up into the artery wall.
The catheter was removed and a bracelet was put over the incisions and inflated.
Overnight the bracelet was deflated a little at a time. My hand changed from blue, to red, to flesh color and the bracelet was removed.
I love it when I get to watch things like this.
The body is built wonderfully, allowing such medical procedures to be performed. For example, while my Radial Artery was blocked by having a big ol catheter rammed into it, the ulnar artery supplied blood to my hand.

I praise you because in an awe-inspiring way I am wonderfully made.
