Stent Deployment and Function Concepts

The video tutorial explains what stents are and how they function in medical procedures. It describes the process of deploying a stent using a catheter and balloon, emphasizing that the stent pushes cholesterol aside rather than removing it. The tutorial also covers how stents become part of the artery wall over time and discusses the materials used in stent construction, such as stainless steel and chromium.

What is the primary purpose of a stent in heart procedures?

• To push plaque out of the way and create space for blood flow

• To remove cholesterol from arteries

• To replace damaged artery walls

• To dissolve plaque in the arteries

How is a stent typically delivered to the heart?

• Through a surgical incision

• Via a catheter with a prepackaged balloon

• By dissolving it in the bloodstream

• Using a laser-guided system

What misconception do people often have about stents?

• They remove cholesterol from arteries

• They are temporary solutions

• They are visible on the skin

• They are made of plastic

What is the initial state of a stent when it is inserted into the body?

• Attached to a wire

• Crimped on a balloon

• Fully expanded

• Dissolved in a solution

What analogy is used to describe the function of stents in the heart?

• Electricians of the heart

• Plumbers of the heart

• Carpenters of the heart

• Mechanics of the heart

What happens to the balloon after the stent is deployed?

• It dissolves in the bloodstream

• It remains in the artery

• It is absorbed by the body

• It is collapsed and removed

Over time, how does the body interact with the stent?

• The stent causes inflammation

• The stent is rejected by the body

• The stent becomes part of the artery wall

• The stent dissolves

What is the role of the balloon in the stent deployment process?

• To measure the artery's diameter

• To remove the stent after deployment

• To inflate and expand the stent against the artery wall

• To dissolve the stent

How long does it take for a stent to become indistinguishable from the artery wall?

• Three to six months

• Over several years

• Within a few days

• Immediately after deployment

What materials are commonly used to make stents?

• Plastic and rubber

• Titanium and aluminum

• Gold and silver

• Stainless steel, chromium, cobalt
