How to ensure adhesion on hard-to-bond plastic substrates

Medical device companies are increasingly using plastic substrates that are tough and sterilization/chemical resistant. But they also come with adhesion challenges. Michelle Gumbert and Patrick Vaughn, Dymax  For medical devices such as catheters, prefilled syringes, vials, test tubes and injector pens, many manufacturers are turning to plastic substrates that are specifically formulated to resist harsh

How slugs are creating better medical adhesives

Slug mucus is the inspiration behind a new adhesive to close surgical wounds and reduce the use of surgical staples, according to new research out of Harvard. Some of the current adhesives on the market can be toxic and stick together tissues weakly. Some can’t be used in wet environments altogether, which can pose a

Dymax touts needle bonding adhesive

Dymax is touting its new 1406-M needle bonding adhesive for manufacturers who want to switch to LED curing in small gauge needle applications. The 1406-M bonding adhesive is designed to be used on smaller surface areas of cannulas and is able to withstand aging and sterilization to reduce cannula substrate failure. The adhesive can be

New biocompatible adhesive glues together soft tissues

Okayama University researchers say they’ve discovered a new type of biocompatible adhesive material made of hydroxyapatite that can glue together synthetic hydrogels and soft tissues. Adhesive organic materials instead of sutures join soft tissues. The method has been around for several decades, but it often has limited biocompatibility and sub-optimal adhesive strength. The researchers at

3 new wound dressings you should know

Surgical dressings are designed to control post-operation bleeding, absorb exudate, ease pain and provide protection for the wound, according to an article relayed by the National Center for Biotechnology Information. If properly taken care of, surgical dressings prevent surgical site infections. According to Johns Hopkins Medicine, the chances of developing a post-surgical wound infection ranges from

Long-term adhesives: Patients have skin in the game

Patients and caregivers have been looking for an option for long-term adhesives. Users of infusion pumps, colostomy bags, cardiac monitors, glucose monitors, health monitors and other devices worn on the skin have long complained that the adhesives used are not good enough. Long-term adhesives, however, have issues with lift (where part of the adhesive loses
