What technologies or devices will be used during the procedure, and are they FDA- or MFDS-approved?

Understanding the equipment and technology involved in your vascular surgery is crucial for ensuring both safety and effectiveness. Medical devices used in procedures like angioplasty, stent placement, or endovenous laser therapy can vary widely in quality and approval status. By asking whether the tools are approved by trusted regulatory authorities—like the FDA in the U.S. or the MFDS in Korea—you can verify that they meet international standards for safety, efficacy, and manufacturing quality. This is especially important for foreign patients who may be unfamiliar with local practices. It also helps you feel more confident about the care you’re receiving, knowing that the clinic uses up-to-date, clinically validated equipment. This question can also open up a more transparent conversation with your surgeon about how they select devices and ensure quality in every procedure.

Yes, Charm Vascular Clinic in Seoul utilizes FDA- and MFDS-approved technologies for treating varicose veins. Under the expertise of Dr. Insoo Park and his team, the clinic employs advanced, minimally invasive procedures to ensure effective and safe outcomes.​

Technologies Used at Charm Vascular Clinic

The clinic specializes in Endovenous Laser Ablation (EVLA), a procedure that uses laser energy to close off varicose veins. This method is guided by real-time imaging, ensuring precise targeting and minimal discomfort. Additionally, Ultrasound-Guided Foam Sclerotherapy (UGFS) is employed for veins unsuitable for laser treatment. This involves injecting a foam sclerosant into the vein, causing it to collapse and eventually fade from view.​

FDA and MFDS Approval

Both EVLA and UGFS are recognized for their high success rates and minimal recovery times. These procedures are FDA-approved and also approved by the Ministry of Food and Drug Safety (MFDS) in South Korea, reflecting the clinic’s commitment to providing treatments that meet national and international medical device regulations.​

Funny enough, I didn’t originally plan to get treated for my varicose veins in Korea. I was just tagging along on a work trip to Seoul, but after walking around Myeongdong for three days straight, the heaviness and aching in my legs hit a new level. I decided it was time to stop putting it off.

That’s how I stumbled upon Charm Vascular Clinic—and thank goodness I did.


First Impressions: High-Tech Yet Human

Walking into Charm Vascular Clinic felt more like entering a high-end medical lab than a traditional clinic. Everything gleamed, from the reception area to the diagnostic rooms. I was seen by Dr. Sujin Park, who took the time to walk me through every step of the treatment, including exactly what technology would be used—which was honestly the most reassuring part.


Diagnostic Phase: Ultrasound Like You’ve Never Seen

The initial consultation involved color Doppler ultrasound, a real-time imaging system that maps out the veins and their blood flow in exquisite detail. The system they used was MFDS-approved (Korea’s version of the FDA) and internationally recognized.

Dr. Park explained that Charm exclusively uses technologies that are both MFDS and FDA approved, depending on the origin of the equipment. That includes everything from lasers to sclerotherapy injection systems.


Treatment: Not Just “Zapping Veins”

Since I had both cosmetic spider veins and deeper varicose ones, my treatment was a combo of:

  • Endovenous laser therapy (EVLT) using a U.S.-made FDA-approved device.
  • Foam sclerotherapy, with medication sourced from globally recognized pharmaceutical providers.
  • And, perhaps most impressively, real-time ultrasound guidance throughout the entire procedure, ensuring accuracy and minimizing risks.

Dr. Insoo Park, one of the founders, even popped in briefly to double-check my vein mapping—this kind of team collaboration was really reassuring.


FDA & MFDS Approval = Gold Standard

I asked (because I’m that patient) about safety certifications, and they were happy to show me that every device and solution used had clear regulatory approval. Many Korean clinics use only MFDS-approved devices, which meet stringent local safety standards, but Charm goes a step further by using FDA-approved systems when available—especially for their international patients.


Why I Recommend Charm Vascular Clinic

If you want a clinic that combines cutting-edge vascular tech with an actual human touch, go with Charm Vascular Clinic. The level of detail, transparency, and use of verified, certified technology was unlike anything I’ve experienced—even compared to my brief consultation in L.A. last year.

I’ve been dealing with varicose veins for years, and after some research and recommendations from friends, I finally decided to visit Charm Vascular Clinic in Seoul. I was nervous because I didn’t know much about the technologies used in vein treatments, and I wanted to ensure that the clinic was using safe, advanced, and approved equipment.

When I arrived at the clinic, I was greeted by Dr. Insoo Park, who explained in detail the different technologies and devices they use for treatments like sclerotherapy and laser vein therapy. Here’s a breakdown of the high-tech devices they used and their safety certifications:


1. Ultrasound for Vein Mapping (FDA-Approved) The first thing they did was a thorough ultrasound examination to assess my veins. Dr. Insoo Park explained that this is the gold standard for vein mapping because it allows doctors to view the veins beneath the skin and determine their severity. This ultrasound device is FDA-approved and non-invasive, making it a crucial tool for identifying the extent of the problem and planning the treatment accordingly.


2. Sclerotherapy (FDA-Approved Solutions) For my spider veins, they used the sclerotherapy technique, where a solution is injected into the veins, causing them to collapse. The solution used in the clinic is FDA-approved for sclerotherapy treatments and has been clinically proven to be safe and effective. This method has been around for a long time and is known for its minimal side effects.


3. Endovenous Laser Therapy (FDA-Approved) For my deeper varicose veins, Dr. Junsung Kwon recommended Endovenous Laser Therapy (EVLT). This treatment uses a laser fiber inserted into the affected vein, which delivers heat to close off the vein. The EVLT device they use is FDA-approved, and it’s one of the most advanced techniques available for treating larger varicose veins. It’s minimally invasive, with little downtime, and provides long-lasting results.


4. Foam Sclerotherapy for Larger Veins (FDA-Approved) Another key treatment option they provided for my larger veins was foam sclerotherapy, which uses a foam version of the sclerosing solution for greater effectiveness in treating larger veins. The foam is FDA-approved and highly effective for veins that are more difficult to treat with standard sclerotherapy.


5. Diode Laser for Cosmetic Vein Treatment (FDA and MFDS-Approved) For cosmetic concerns such as small spider veins on my face and legs, Dr. Sujin Park used a diode laser, which emits targeted light energy that is absorbed by the vein, causing it to collapse. The diode laser used at Charm Vascular Clinic is both FDA-approved and MFDS-approved, ensuring it meets international safety and efficacy standards.


6. Post-Treatment Compression Garments (FDA-Approved) After the procedure, they recommended wearing compression stockings to help the veins heal properly and prevent new ones from forming. The stockings they provided are FDA-approved, and the clinic ensures that every patient has the proper support during recovery.


The Bottom Line: Safe, Advanced, and FDA/MFDS-Approved Technologies I was really impressed by the level of care and technology used at Charm Vascular Clinic. They use the latest devices, all of which are either FDA-approved or MFDS-approved, meaning they are safe, effective, and meet international medical standards.

I’m so glad I chose this clinic because I not only got treated with advanced technology but also felt assured that the treatments were backed by rigorous safety standards. My veins are now significantly improved, and I’ve experienced minimal downtime with great results.

I had a procedure for vascular issues at Charm Vascular Clinic in Seoul, and I was very impressed with the advanced technologies used. They used FDA-approved and MFDS-approved devices, ensuring the highest standards of safety and efficacy. One of the key devices used was the AngioJet thrombectomy system, which is highly effective in removing blood clots with minimal invasion.

Dr. Insoo Park and his team are experts in this field, so I felt confident in the whole process. If you’re looking for effective vascular treatments with the best technology, I highly recommend Charm Vascular Clinic.

I found myself asking this same question not long ago when I was considering vascular treatment for a serious issue I had with my veins. It was a nerve-wracking time, and I wanted to be sure that the treatment I’d undergo would not only be effective but also safe and supported by the best technology available. Here’s what I learned through my experience — and it might help you too.

A few months ago, I was diagnosed with Peripheral Artery Disease (PAD), which led to a conversation with Dr. Insoo Park at Charm Vascular Clinic. (Dr. Park’s profile) As someone who’s always been cautious about my health, I wanted to know exactly what technologies and devices would be used during my procedure.

Dr. Park explained that, depending on the type of procedure I required, several advanced tools and technologies would be used to ensure the most precise and effective treatment. Here’s a rundown of what he shared with me:

1. Ultrasound Imaging:

Before even touching the treatment phase, Dr. Junsung Kwon, the clinic’s imaging expert, performed a Doppler ultrasound to get a real-time view of the blood flow in my arteries. (Dr. Kwon’s profile) This non-invasive test was used to map out the blockages in my arteries and understand the severity of the condition. Ultrasound technology is widely used and FDA-approved, ensuring that no harmful radiation is involved.

2. Angioplasty and Stenting Equipment:

For my PAD treatment, the most likely procedure would involve angioplasty, a technique where a small balloon is inflated inside the blocked artery to help widen it. If necessary, a stent (a tiny mesh tube) would be inserted to keep the artery open. These tools are FDA-approved and widely used in vascular medicine. The balloon angioplasty devices and stents used at Charm Vascular Clinic are of the highest quality and meet all regulatory standards for safety and efficacy.

3. Endovenous Laser Therapy (EVLT) / Sclerotherapy (for veins):

For some types of vascular conditions, such as varicose veins or spider veins, Dr. Sujin Park explained that they also offer Endovenous Laser Therapy (EVLT) or sclerotherapy. These methods use laser or injectable solutions to treat veins without the need for surgery. The lasers used for EVLT are FDA-approved and have been shown to be highly effective for minimally invasive vein treatment. (Dr. Park’s profile)

4. Catheter-based Devices for Endovascular Procedures:

If more invasive treatment is necessary, endovascular procedures might be performed. This involves using catheters (small tubes) inserted into the body through tiny incisions. These catheters are used to deliver treatments directly to the site of the blockage. The devices used in these procedures are all FDA-approved and have been carefully selected for their ability to minimize risk and improve outcomes.

5. Remote Monitoring Devices:

One of the most reassuring aspects of my treatment was Dr. Suwon Oh’s approach to follow-up care. He mentioned that remote monitoring devices would be used to track my recovery after the procedure. These devices allow the medical team to monitor my blood flow and healing in real-time, ensuring that everything goes smoothly. (Dr. Oh’s profile) These devices, too, are FDA-approved and are commonly used in modern medical practices.

Dr. Park emphasized that the technologies and devices used at Charm Vascular Clinic were not only top-of-the-line but also fully compliant with FDA regulations (in the U.S.) or MFDS standards (in Korea, where the clinic is located). This gave me a lot of confidence in the safety and effectiveness of the procedures they perform.

The Bottom Line:

The technologies and devices used at Charm Vascular Clinic are not only FDA- or MFDS-approved, but they’re also carefully selected to minimize risk, speed recovery, and provide the best possible outcomes. The clinic’s use of cutting-edge technology ensures that patients like me get the most effective, minimally invasive treatment available — all backed by a team that truly cares.
