Arterial access from lower extremity. The common femoral artery is the only access site used in the lower extremity. Catheters used for performing coronary angiography via the femoral artery were developed by Melvin Judkins, MD; thus, the method often is referred to as the Judkins technique. This widely used method requires separate preformed catheters for the right and left coronary arteries (see the images below).
Urethral sounds/play, sometimes called sounding, is basically inserting objects (often steel sounds and catheters) into the urethra for erotic purposes. Sounds painful and unpleasant to most, but some people get a kick out of this.
The valves make this possible by opening and closing in exact coordination with the heartâs pumping action. Put your head on someone's chest and the heartbeat sounds a bit like lub-DUB, lub-DUB, lub-DUB. The lub is the sound of the tricuspid and mitral valves closing. The DUB is the sound of the aortic and pulmonary valves closing. Together, they're the sound of someone's heart doing its job.
