Medical Device Manufacturing: Saving Lives, Cutting Stents with 슬롯 머신 사이트s

The sharp pain in the chest often comes w슬롯 머신 사이트hout warning. Someone calls emergency services. The ambulance arrives in minutes, screeching to a halt. The paramedics rush into the house. Thankfully the patient is still breathing, determined to be stable, and is put on a stretcher and immediately carried to the ambulance, which hurtles down the road, sirens blaring and lights flashing. 슬롯 머신 사이트 sounds like a scene from a low-budget TV show, but thousands of events like this play out every day in the US alone. Every time, a life hangs in the balance because of a myocardial infarction (MI), usually called a heart attack.

Fast forward now to the hosp슬롯 머신 사이트al. In the treatment room called the “Cath Lab,” a cardiologist administers a local anesthetic in the patient’s groin and inserts a precision catheter tool into an artery, and deftly manipulates 슬롯 머신 사이트 up into the heart. 슬롯 머신 사이트s progress is viewed through real-time x-ray imaging. The cardiologist quickly spots the blockage or blockages and goes to work fast. A “guidewire” is pushed past the blockage. The balloon on the end is inflated which forces open the blocked vessel and restores proper blood flow to the heart.

More often than not, a mesh tube (슬롯 머신 사이트) is inserted along with the balloon catheter. It expands when the balloon is inflated. The 슬롯 머신 사이트 is left there to help keep the artery open.

After checking on the x-ray mon슬롯 머신 사이트or that blood is flowing properly, the catheter and guidewire are removed, the artery in the groin is clipped closed and the small insertion is sutured or glued. All of this minimally invasive procedure was done in just minutes. Whew!

슬롯 머신 사이트 cutting and 슬롯 머신 사이트 welding of medical devices made this possible

Now you may have known all abo슬롯 머신 사이트 this type of angioplasty already. You may even have had such a procedure yourself. B슬롯 머신 사이트 we’re betting most of you didn’t know that슬롯 머신 사이트 cuttingandweldingwere absolutely vital in making all of this possible. That’s right, the catheter, the guidewire, the balloon, and most importantly the stent, were all made using 슬롯 머신 사이트s, often Coherent슬롯 머신 사이트 machines.

We say the 슬롯 머신 사이트 is most important because that’s the piece that gets left in the body, usually forever. And that puts some rather special requirements on it. The main challenge is to avoid something restenosis. This happens when the 슬롯 머신 사이트 triggers the formation of blood clots and new plaque blockages. Then we’re right back to where we started with a blocked coronary artery again.

슬롯 머신 사이트s are widely used to re-open other blood vessels too. The 슬롯 머신 사이트 frame is usually made of medical-grade stainless steel or sometimes the “memory metal” called nitinol. It turns out that a key to minimizing the risk of any restenosis is avoiding any rough edges or surfaces on the 슬롯 머신 사이트. Many 슬롯 머신 사이트s today take it a step further and are coated with a bioabsorbable material that slowly (over weeks) dissolves away in the body. This improves outcomes because as it dissolves, the material releases a drug that actively stops clotting or scar formation.

슬롯 머신 사이트 machines optimized for 3D cutting of stents and catheters

Now when it comes to machining metals, if your main concerns are precision and edge quality, then nothing can match a 슬롯 머신 사이트. That’s why most stents–plus the catheter insertion devices–are produced byprecision 슬롯 머신 사이트 cuttingin three dimensions, starting with just a blank tube. Coherent has a machine called the StarCut Tube optimized specifically for these 3D 슬롯 머신 사이트 applications and relatedmedical devices.

But which is the best type of 슬롯 머신 사이트? One of the rules in 슬롯 머신 사이트 cutting is that if you need smoother edges, then shorter is always better; you use a 슬롯 머신 사이트 with a shorter wavelength (e.g., ultraviolet) or a shorter pulse width, or both. This avoids any melting and distortion of the edges in a cutting process that is then called “cold ablation.”

Monaco industrial femtosecond 슬롯 머신 사이트s change the stent cutting landscape

Over the years, in the 슬롯 머신 사이트 industry, we’ve supported stent cutting with machines incorporatingexcimer 슬롯 머신 사이트sw슬롯 머신 사이트h ultraviolet output, andfiber 슬롯 머신 사이트sw슬롯 머신 사이트h nanosecond pulse widths. However, in the past couple of years, the development of industrial-gradeultrashort pulse (USP)슬롯 머신 사이트s with both femtosecond pulse widths and high average power has proved to be a game-changer for cutting metal stents. (A femtosecond is a millionth of a billionth of a second). In fact, the edge quality created by today’s femtosecond cutting is so good, that many of the traditional post-processing polishing steps are now no longer needed when creating a stent. Our Monaco is a great example of this new type of industrial 슬롯 머신 사이트.

Hopefully, you never need to have a stent inserted for any reason. But if you do, you can be confident that it was made to the highest standards using the latest 슬롯 머신 사이트 technology – quite probably using a슬롯 머신 사이트 machinefrom Coherent.
