Meet the Duo Venous Stent System: A Game-Changer for Treating Vein Blockages!

Hey, Curious Minds! ??

Well... well... it's been a minute, hasn't it? I had to take a little hiatus for some personal stuff (life happens, right?). But fear not, I'm back and ready to roll with more awesome content! ?? This won't be happening again anytime soon... at least I hope not! ??

Today's Content

• Philips has launched its Duo Venous Stent System in the U.S. to treat patients with blockages in their veins, the company said Wednesday.
• The implant, which won approval in December, is designed to address the root cause of chronic deep venous disease and comes in two forms for use in different types of veins.
• The Duo Venous Stent System was successfully used for the first time outside of a clinical trial on June 11 by Dr. Erin Murphy, a vascular surgeon and director of the Venous and Lymphatic Program at the esteemed Sanger Heart & Vascular Institute, Atrium Health, in Charlotte, N.C. Murphy was also an investigator in the VIVID study, which helped the device receive FDA approval.

Self-Expanding Stents?

So, what's the deal with self-expanding stents? ??These are tiny mesh tubes made from a special material, usually a metal alloy like nitinol, that automatically expands once inside the body.

How do they work?

The Stents work in the following manner - which are Insertion, placement, and Expansion

• Insertion: The stent is compressed into a small size and loaded into a delivery catheter (a thin tube).
• Placement: The catheter is guided through the blood vessel to the site of the blockage or narrowing.
• Expansion: Once in place, the stent is released from the catheter. It automatically expands to fit the size of the blood vessel, without needing any external force.

Why do they use it?

• They are used to treat conditions where blood vessels are narrowed or blocked, such as coronary or peripheral artery disease.
• Self-expanding stents are particularly useful in blood vessels that are prone to compress or collapse, as they can adjust and maintain their shape over time.

Innovation of Vesper Medicals

Now, let's talk about Vesper Medical's game-changing innovation:

• A range of self-expanding stents installed on disposable delivery devices makes up the Duo Venous Stent System. Vesper made the stents to dilate blocked veins. Restoring blood flow may enhance quality of life by reducing venous disease symptoms like pain, edema, and skin discoloration. In a device trial, Philips monitored progress on observational quality-of-life objectives.
• Philips acquired the device in its 2022 takeover of Vesper Medical. The company paid 227 million euros [Put 20 and 6 zeros behind it..] upfront for Vesper to expand its image-guided therapy business.

Duo Venous stent system working

• The Duo Venous Stent System is a medical device used to treat blockages in veins (the blood vessels that carry blood back to the heart). It is specifically designed for veins, which are different from arteries (the blood vessels that carry blood away from the heart).
• Now that it is working, It consists of two types of stents - Duo Hybrid Stent and Duo Extend Stent.

Duo Hybrid Stent

• This stent has a special design that combines different sections with varying mechanical properties (like flexibility and strength) into one stent. This makes it adaptable to different parts of the vein.

Duo Extend Stent

• If the blockage in the vein is long, the Duo Extend Stent can be added. It fits smoothly with the Duo Hybrid Stent to cover the entire length of the blockage.

Its overall benefits!

1. These two stents are designed to be used together. They minimize the chances of breaking (fracturing) or getting damaged (corrosion).
2. They can be used in smaller veins, which are harder to treat with other types of stents.

To conclude

1. Self-expanding stents provide consistent support by automatically expanding to fit the vessel, ensuring it remains open.
2. They are essential in treating blocked or narrowed vessels, particularly in coronary and peripheral artery diseases, improving patient health.
3. These stents conform to the body's movements, reducing the risk of complications and enhancing overall patient quality of life.
