Small Changes; FDA and the 510(k)

Tom Waits once sang of a character named Small Change, who apparently “got rained on with his own .38,” and device makers might sometimes have felt as though small changes to their devices didn’t always work out so well, either.

Pad Printing On Textured Surfaces

Textures vary according to their individual depth, the degree of draft on the sidewalls, and the frequency of peaks and valleys for a given surface area. Some textures are more difficult to print successfully than others, and there are certain textures that are simply impossible to cover completely.

The RX Factor – Medical Plastics And Adhesion

Although polymers have suffered through some tough media disparagement as of late (biodegradability issues) it is highly unlikely that these polymers are replaceable for medical device manufacturing. These specialized materials are indispensible for providing low cost but effective vehicles for delivering everything from successful operating techniques to therapeutic medicines.

The Importance of Medical Grade Ink

Medical grade inks used to mark medical devices should meet important safety standards. The United States Pharmacopoeia (USP) 30, NF 25, 2007 standard also known as Class VI is widely used to comply with stringent FDA rules for products that come in contact with the human body.

Plasma Treatment for Medical Grade Plastics

Many medical devices are made from medical grade plastics that typically have low surface energy.  It is often necessary to modify the surface energy in order to guarantee the adhesion of any permanent markings as well as to improve device performance.  By altering the surface properties, critical markings on devices such as catheters adhere better and they can slide and maneuver more easily within the body.
