How Thin Film Vacuum Coatings are Used in Medical Technology

PVD systems are used to apply thin coatings to medical devices, creating equipment that is less-abrasive and easier for patients to handle.

You don’t have to go back one hundred years to see that medical technology has come a long way. We can now perform heart surgery through veins in the leg, and we are increasingly looking for more non-invasive methods to help patients with serious ailments. Using a process called thin film vacuum coating, doctors are able to do far more inside the body without surgery than ever before.

Vacuum Coating Explained

A PVD System heats special chemicals to prepare them for application on the substrate, which is the object that will receive the coating. The substrate is placed, along with the chemical, inside of a vacuum sealed chamber. Then, heat is applied to the chemical until it breaks down into particulate matter. Air circulates the particulate matter around the chamber until the chemicals coat the substrate.

The end result is a thin coating on a substance. This is extremely important to medical professionals, who need very specific tools to care for patients.


PVD Thermal Evaporation creates a thin film around the substrate that is almost microscopic. When someone needs a catheter, or some other form of implantable device, the chemical coating creates a non-stick coating. This makes the device easy to slide in and out of a patient without causing extreme discomfort. We also see this in use in imaging machines, especially related to the hardware. Chemicals can make hardware more conductive, allowing for more power and efficiency from the machines used to x-ray patients or give them full-body scans.

Making Medical Devices Less Invasive

Polymers are hydrophobic by nature, so plastic devices like catheters cause friction when they are used on a patient. This friction causes extreme discomfort when in contact with body tissue. Medical scientists have been using a new process that uses aqueous medical device coatings on catheters and other devices. This “slippery when wet” design is hoped to help manage some of the discomfort associated with these medical procedures.

The solution is applied directly to the surface of the medical device, where it is likely to come into contact with skin or blood. The coating renders the device slippery, which also helps expedite the delivery of the device. Scientists hope to create a device soon that will actually help medical devices navigate the body’s twists and turns. That technology is not quite here, but water-based coatings are a step in the proper direction.

There are essentially two types of coatings used in the medical coating market. There are water based lubricants, and solvent based. These solutions are applied through a magnetron sputtering system that uses heat, UV, plasma and corona to help apply a thin coating to medical devices.

Water-based solutions offer a few advantages over solvent based methods. For one, the process is much friendlier to the environment because it relies on fewer chemicals. The lack of these inorganic compounds eliminates residual build up on the device as well, helping to keep medical devices functioning for much longer.

Water-based lubricants covalently bond with a non-water-soluble polymer. The molecules blend, which yields a chain of biocompatible polymers. The polymer chain is incorporated into the coating on the device, which becomes a kind of anchor. The device becomes lubricated as the polymers come into contact with bodily fluids.

When this mixture is applied to catheters, guide wires, balloons and other devices, it virtually eliminates any friction felt by the patient. That means that as soon as the device enters the patient’s blood stream, he or she will barely feel a thing as it is slid into place. Furthermore, it is hoped that these coatings will create a strong adhesive that helps to keep devices in place for a longer life span than current methods.

Water-based coating is an amazing technology that has the promise of delivering medical machinery in minimally invasive procedures. In the future, devices that end up in our bodies will receive these coatings to help us stay healthy without adding more chemicals to our blood stream.

Tips on Improving Your Home’s Air Quality

This article was written by Your Filter Connection

Many of us spend a great deal of time inside our homes. But unfortunately, the quality of the air we breathe inside the house might not be so healthy. Our homes trap all kinds of contaminants, from odors and dust, to bacteria, viruses, and allergens. For this reason, many homeowners invest in a variety of machines designed to improve the quality of the air inside the home. Modern machines such as home cooling systems, air filters, and humidifiers can all help to clean the air we breathe at home.

But simply owning these machines doesn’t guarantee fresh air. It’s important to take care of them. Here are a few tips on how to improve your home’s air quality.

Replace Filters on Time

Whether you own an air conditioner, air filter, humidifier, or all three machines, the key to making sure they work properly and improve the quality of the air is changing the filters on time. The very purpose of an air filter or humidifier filter is to trap harmful contaminants from circulating back into the air. But a dirty filter won’t get the job done.

To freshen up the air you breathe, make sure to replace the filters at least once a month. You might need to replace them more often depending on the environment in which you live. A great way to know when it’s time to replace the filter is when it’s visible dark or dirty. You can also tell when it’s time to replace the filter if it has an indicator light.

Size Matters

When it’s time to replace your filters, it’s important to buy the right size filter.  Air cleaner filters come in a variety of sizes. If you buy a filter that is too small, the system will not work properly. If you purchase a filter that is too big, it simply won’t fit inside of the unit. Check the owner’s manual for the right size filter. Then, find a retailer online through which you can purchase filters by size. Whether you need 3m filters or one inch filters, the right size filter will make a world of difference in the performance of your air purifier.

Say No to Generic Filters

When your Honeywell furnace needs a new filter, it’s important to purchase a Honeywell furnace filter from a company such as Your Filter Connection. In other words, the name brand is very important when buying replacement filters. Buying a generic or low-quality filter that was not created for your machine might harm the unit. A generic filter might also not work as well as a name brand filter. While fresh air is usually referred to the air outside of the home, it’s possible to improve the quality of air inside the home by using the tips mentioned above.


Your Filter Connection is an online retailer of heater and cooling filters from name brands such as Filtrete and Accumulair. Visit the website to purchase a 3m air filter today.

Top Ways to Improve Chronic Pain

Are you living with chronic pain? You’re not alone. About 100 million Americans suffer from some type of chronic pain, according to the Institute of Medicine of the National Academics. Chronic pain has been known to severely impact quality of life, cause depression, and reduce energy. Many people with chronic pain have trouble concentrating and others are unable to get a good night’s sleep. Chronic pain can also be expensive; living with ongoing pain can not only lead to more medical bills, but also loss of income for calling in sick to work.

But there is good news. Whether you have been living with chronic pain for days, weeks, months, or even years, you can do something about it today. There are many ways you can combat chronic pain and improve your quality of life. Here’s a list of the most common pain management therapies known to tackle everything from daily aches and pains to chronic migraines and pain caused by car accidents.

Get cracking. Chiropractic therapy or adjustment is designed to correct structural alignment and enhance your body’s overall function. While it’s not for everyone, chiropractic care is used to treat all types of chronic pain, including neck pain, headaches, and low back pain, the three most common types of pain experienced by people in America. However, chiropractic therapy is also used to treat chronic pain caused by car accidents, work injuries, and stress. Find a San Diego chiropractor you can trust and talk about gentle but effective ways to get your pain in check.

Say yes to needles. Acupuncture needles, that is. By inserting tiny needles into various places throughout the body, this traditional Chinese medicine has been known to relieve chronic pain including headaches, low back pain, migraines, and menstrual cramps. Although once considered “alternative medicine,” acupuncture is now covered under most insurance policies.

Try rehabilitation. Find a specialty medical clinic that offers rehabilitation programs for chronic pain. These types of programs are essentially personalized pain management therapies tailored to your unique pain, injury, or medical condition. An effective rehabilitation program for pain management in San Diego usually encompasses a combination of various treatments, such as chiropractic treatments, rehabilitative exercise, and acupuncture.

Whether you suffer from lower back pain, migraines, or neck pain, experiencing pain on a regular basis can significantly lower the quality of your life. Stop living with chronic pain and take advantage of the pain management therapies available to you today.

The Best Skin Care Comes from Nature

Maintaining healthy skin all over your body and face is important. However, choosing the best skin products can be daunting and overwhelming. There are seemingly infinite options on the market, each one promoting its superiority over another product. How do you know what is the best for you?

While everybody’s skin is different, there is one type of product that benefits everybody. Natural products offer the best skin care for every skin type. Not only are the toxin and carcinogen free but they are chock full of health natural alternatives that are much better for your skin.

Your skin absorbs chemicals and creams that you put on it, so you want to be careful what you use. Since synthetic serums use such terrible ingredients (some banned in Europe!), consider turning to natural ones. Cosmetic professionals have honed their skills over the years to combine the best that nature has to offer to create healthy and effective products.

One natural substance being used in beauty products is peptides. Studies show that peptides encourage natural skin reactions that regenerates the collagen, creating a youthful, smooth look. Peptides strengthen circulation around your eyes to minimize discoloration and swelling by increasing firmness and elasticity.

Not only are these natural products much better for your skin, they are much better for the environment. The same people creating healthy products also have made sure the carbon footprint left behind the manufacturing process is as small as possible. What is there not to like about this stuff?
