Reducing particulate matter within medical device coatings can improve its’ effectiveness.
Endovascular devices often utilize medical device coatings to aid endovascular devices enter the body in a safe and efficient manner. The concern for many surgeons when they are implanting a device within the human body is the risk of the body reacting to the, for example, catheter.
Not only can this procedure create health complications for the patient that can prove to be fatal, but preexisting conditions can cause dysfunction that completely cancel out the beneficial effects of the procedure, essentially nullifying the entire thing.
Hydrophilic Coatings
The evolution of medical coatings has led to improved performance parameters. Take hydrophilic coatings for instance. The lubricity is designed to reduce the overall frictional force of the entering device. Earlier hydrophilic coatings were measured by the lubricity and durability. While they are still considered in today’s research, another parameter is included within testing, known as particulate generation.
Medical Devices Are Seeking Improved Measures
Medical device coatings are undergoing more extensive research. As stated earlier, particular generation has been considered an important design criterion to consider in the newer models of these coatings. By internally testing the coatings through the process of PECVD, one can generate substantial information about these particulates. Because more attention is being directed towards these particulates, all signs are pointing toward improved forms of coatings.
In addition to the increased evaluation of particulates in their hydrophilic coatings, different methods are being implemented to suggest that there will be less active particulates in the new form of device coatings.
