Richard Hirschman extracts a long length of whitish material from an artery of the deceased.

Scene from Died Suddenly, from 50:34 following. Original: https://rumble.com/v1wac7i-world-premier-died-suddenly.html?mref=lveqv&mrefc=6.

Transcript, Richard Hirschman speaking: 'This is the iliac artery, and the clot coming out of the iliac, normally we don't see clots in the iliac.. [corrects himself] in an artery, usually they are in veins.. and I'm probably not going to be able to get it all, [he pulls out 2-3 ft of material]... this is not normal... I'll put it by the side of this one.. the big [thick] one came out of the vein, the small [thin] one came out of the iliac artery itself.'

I think the introductory section [00:00 - 00:07] was filmed on a different occasion to the main section, since the gloves look different. The filmmaker has linked the two by starting the audio before the end of the introductory scene. I guess the introduction was filmed by the makers of Died Suddenly, and that the main section was footage provided by Hirschman, probably filmed by his assistant while they were at work.

The main points are:

i) the material is coming out of an artery rather than a vein;
ii) it is extremely long;
iii) at various points in the video the material can be seen to be whitish in colour;
iv) it is strong enough to be extracted in a single length without breaking.

Update: The same footage, but at a different orientation, was shown on the Jane Ruby show on 31 January 2022: https://rumble.com/vtr470-worldwide-exclusive-embalmers-find-veins-and-arteries-filled-with-never-bef.html beginning 7:45.
