Final answer:
Minimally invasive hemodynamic technologies are devices that enter the body without entering the heart or pulmonary artery. They are used to measure pressures in the cardiovascular system and perform procedures like angioplasty.
Step-by-step explanation:
Minimally invasive hemodynamic technologies are devices that enter the body without requiring entry into the heart and pulmonary artery, or through a large vessel. These technologies are used to measure pressures in the cardiovascular system and to perform procedures such as angioplasty. For example, angioplasty is a procedure where a catheter with an expandable tip is inserted into a superficial vessel and a balloon on the tip is inflated to widen the vessel and improve blood flow. Stents may also be inserted to reinforce the walls of the vessel.
