I would like to draw your attention to a new video available that details a new lubricious coating called Hydrosleek2. To access the video click on the button below, and enjoy.
Within the presentation, you will find information on coefficient of friction and processing of the coating, both before and after sterilization and aging. In previous posts I have talked about the importance of this sort of data: a company displaying friction data must qualify whether the data is for aged and/or sterilized coating or virgin coating. They must also talk about the nature of the testing that was performed on the coating to obtain the friction data, especially for durability. Recall a study we did on the effects of pinch testing parameters on hydrophilic coatings.
Biocoat, Inc., maker of lubricious HYDAK® hydrophilic coatings introduced three new hydrophilic coatings for medical devices to its classic lineup.
", the new successor to the original HydroSleek
lubricious coating, with improved processing and biocompatibility. "The HydroSleek Kit
" is another variation on the HydroSleek coating, which allows the product to be stored and transported under a wider array of conditions. Third, the "Hydak® T-040 Kit
" is a remake of another classic, Hydak® L-110
, also allowing for wider availability to Asian and European markets.
All of these coatings are based on high molecular weight Hyaluronic Acid (HA). This technology has applications among a range of fields including ophthalmology, urology, cardiology, endoscopy, and neurovascular. HydroSleek coatings have overcome the trade off between lubricity and durability seen in cross-linked coatings. Additionally, HydroSleek involves a heat-cure process so both ID and OD may be coated without the concerns surrounding UV curing.
These new products will act as Biocoat's front line solution to medical device firms seeking to reduce surface friction for their devices. Each of these new products possesses the same beneficial characteristics of the family of HYDAK® coatings, plus advancements device manufacturers have requested.

An archive of the webinar we recently announced on hydrophilic and hydrophobic coatings is now available to everyone for download. Please stop by and grab the file and listen to it.
Click here to download the hydrophilic coatings webinar.
The webinar was sponsored by Biocoat and Specialty Coating Systems. Half of the presentation by Josh Simon is actually about hydrophilic coatings and the second half by Lonny Wolgemuth talks about hydrophobic coatings. Remember, hydrophilic means "water loving". Hydrophobic means "water fearing". The webinar sets the record straight on which is which and why you would want to use some in specific applications.
For both coatings, lubricity is discussed, i.e. how slippery they are respectively, as well as some basic mechanical properties and medical device applications.
All in all, I am told this is a pretty good overview of coatings, and it is a nice place to start if you are just beginning your research on this area for possible future products or medical devices.
Now that I am back from the west coast and have had a chance to dig out from the mountain of work waiting for me when I got back, I can reflect on how the show went. In a word: outstanding. The traffic at our booth was quite good. We actually saw a 50% jump in leads from last year, which is amazing since this has always been the
biggest lead generating show for us out of all of them to begin with. With some trepidation, I can venture to guess that the economy is on the road to recovery, although the medical sector never did that badly even in the worst years, 2008 and 2009. If you are low on cash, you may forego that dinner and that movie, but if you have chest pains, you don't forego that visit to the doctor. Right?
Another reason why I like this show is it gives me a chance to visit with my hydrophilic coatings "family", that somewhat incestuous tightly-knit group of competitors which all sell hydrophilic coatings among other things. It was good to see everyone again and to meet some people with whom I have not yet had the pleasure. My impression is that this business suffers a little bit from ADD in that few companies make their living only from hydrophilic coatings. (Perhaps because that is tough to do when the revenue from them can be small at times. Even my own company dabbles in the fertility industry.) All of these companies do hydrophilic coatings.... and something else. It is fascinating to see what their other ventures are: plasma treatment, biomaterials development, chemicals, contract manufacturing, contract manufacturing equipment, and others.
Beyond that, I like to see what the medical device companies are doing, and to find out more about why they are using lubricious coatings for their surfaces. I learned a lot of new information about catheters, guidewires, and some less common devices on this trip. Looking forward to servicing the new leads and seeing where they.... lead.
Having just gotten back recently from the BIOMEDevice show in Boston, I wanted to share some of my impressions. As far as coatings companies go, there were a few of them there. A couple of them were industrial coaters that seemed eager to try their hand in medical devices, and then there were Biocoat and Advansource who have lots of experience already in the field. Compared to the bigger shows like MDM West, this was sort of dinky, about 5,000 attendees and exhibitor personnel. On the other hand, MDM West is actually a conglomerate of maybe 10 shows, most of which have little to do with healthcare. This show in Boston was all healthcare.
We did alright for leads too. The MDM show in Minneapolis yields about the same as this one. The take-away message from this is that companies are still seeking coatings. There are a lot of startups and big companies alike that have still not completely caught onto the utility of hydrophilic coatings. Granted, many more advanced companies are looking for more advanced coatings, but you would be surprised just how many companies out there could really use a basic hydrophilic and do not have one. It is almost like they never heard such a thing existed, sometimes, even though this technology's roots stretch all the way back to the 1950's and 60's.
If you happen to live up in the Boston area, or happen to be running in the Boston Marathon a day or two before it, we will have a booth at this show and would love to see you. We are Booth #813.
Admission to the exhibit hall is free if you register by going to biocoat.com
and clicking on the show coupon towards the bottom.
At the show we will have a demonstration of the coatings, and we will also be raffling off an iPod Touch 32GB to one lucky winner.
Biocoat and Formacoat had a great show at MDM Minni. It has taken me this long to actually get caught up on the leads and the work I have missed in the process, but everything is moving again now. This year, we received about 70% more leads than last year, which is a good sign.
The show looked pretty good. I did not notice any markedly lower attendance. It seemed to have around 10,000 people, as usual, and we had plenty of crowds at our booth throughout a good portion of the time.
That's all for now!
This year, Biocoat and Formacoat will be co-exhibiting at the Medical Device Manufacturer's (MDM) conference in Minneapolis, MN on Oct 21 and 22nd. Biocoat
provides coating technologies for medical devices, including hydrophilic and antimicrobial coatings. Formacoat
is a contract manufacturer that specializes in Biocoat's Hydak® technology platform.
Stop by booths 950 and 951 to see us if you get the chance. We will be giving away a free iPod Touch in a drawing!
I am not certain how old this article is, but over at Medical Device Network
there is a good breakdown on hydrophilic coatings.
It is a lot like the article I have written to appear in this May's issue of Medical Design. It outlines the basic history of hydrophilic coatings, and some basic features of the hydrophilic coatings by Biocoat
/Surmodics. The hydrophilic coating "breakdown" makes a good point about breakdown of hydrophilic coatings. One major complaint about hydrophilic coatings is that they do not stand up well to abrasion, mainly because they are hydrogels on a microscopic level. This is why you do not see many of them in applications such as Orthopedics, aka Medical Carpentry, where the surgeries are not gentle, and the surfaces of devices can easily be dinged or scratched with routine procedures. Of course, if some company could make a hydrophilic coating that does not rub off, scratch off, chip off, or burn off in the normal conditions seen in normal orthopedic or dental procedures, they could probably write their own ticket. However, right now, as far as I know, that is not the case.
Horsham, PA (April 2, 2009) – Biocoat, Inc., maker of lubricious Hydak® hydrophilic coatings
, and Agion Technologies
, the worldwide leader in natural silver-based antimicrobial solutions, today announced a co-marketing agreement to develop and promote a coatings product line featuring Agion’s antimicrobial protection for medical devices.
This agreement utilizes technology co-owned and patented by Agion and Biocoat for hyaluronan coatings that incorporate silver-based antimicrobial properties. Coatings that take advantage of this synergistic combination of non-thrombogenicity and antimicrobial properties are now available to device makers for immediate evaluation in their products.
“We believe that Agion's silver zeolite technology and the unique properties of coatings based on hyaluronic acid will be a major advance in medical coatings,” said Djoerd Hoekstra, CEO of Biocoat. Dr. Josh Simon, Senior Product Manager for Coating Technologies adds, “This is an exciting development not only because it allows us to produce a lubricious coating with antimicrobial properties, but also because of the market timing and prospects for further development of advanced medical coatings.”
“Medical devices that incorporate Agion’s natural antimicrobial technology actively inhibit the growth of microbes on the device’s surface for the life of the product,” said Paul Ford, CEO of Agion Technologies. “This partnership will allow us to extend our antimicrobial protection to medical devices that choose Biocoat as their coatings provider.”
Coatings that release silver are used on catheters, particularly central venous and urological catheters, where they have been shown to reduce the amount of microbes found on their surfaces. Recently, Medicare declared it will no longer reimburse hospitals for the treatment of some preventable conditions. This is a strong incentive for companies to develop antimicrobial protected devices for prophylactic and therapeutic use.
Biocoat's Hydak product line of lubricious hydrophilic coatings
are based on hyaluronic acid, which occurs naturally in the body and has non-thrombogenic properties. The hyaluronic acid in the coating can be crosslinked or non-crosslinked
on a surface to varying degrees in order to control durability in applications where abrasion may occur.
The cornerstone of Agion technology is silver, a naturally occurring and highly effective antimicrobial agent. Silver has long been known for its antimicrobial properties and Agion's zeolite carrier provides many benefits over other antimicrobials that are alcohol-, chlorine-, or ammonium-based. Silver is proven to be safe with no toxic affects on people, plants or animals. Agion technology operates at the surface of a product through the controlled release of silver ions which attack microbes and inhibit their growth in three different ways. They offer a variety of silver-based technologies to suit various manufacturing and product requirements.
