Graphite-embedded plastic kills 99.99% of bacteria on contact
Plastic surfaces embedded with graphite nanoplatelets reportedly can prevent hospital-acquired infections (HAIs), killing 99.99% of bacteria that try to attach, according to research from Chalmers University of Technology in Sweden.
Eastman Launches Next-Gen Copolyesters for Medical Device Housing
New Tritan MXF copolyesters aim to answer medical device companies’ requests for flame-resistant materials with chemical resistance, higher impact strength, and easier processing.
Dural Sealant Patch Made of Bioresorbable Polymers Earns CE Mark
Liqoseal, a dural sealant patch made of bioresorbable polymers, has received the CE mark and is now commercially available in Europe. Developed by Polyganics, the patch could help reduce cerebrospinal fluid (CSF) leakage after elective cranial surgery.
Bioresorbable Patch Offers New Alternative for Arterial Healing
When a patient experiences 70 percent or greater stenosis in the carotid artery — a condition that can cause lack of cerebral blood flow, stroke, and in some cases, death — surgeons perform a procedure known as carotid endarterectomy (CEA) to remove the plaque causing the artery stenosis.1,2 The procedure consists of a longitudinal incision made from the common to the internal carotid artery, allowing for removal of the plaque that deposits in the bifurcation.
New Biomaterials Speed Trend Toward Smaller Medical Devices and Implants
Ultra-high molecular weight polyethylene fibers offer performance characteristics that could benefit both patients and surgeons.
New Silk Materials Can Wrinkle into Detailed Patterns, Then Unwrinkle to Be “Reprinted”
Scientists engineer on-demand high-resolution wrinkling for reversible printing and thermal regulation.
40 Years of Medical Device Implants
A silicone manufacturer reflects on the industry’s changes as the company marks 40 years of innovation.
Fixating on PEEK: The Implant Advantage
As a precision machiner of plastics, I’ve found PEEK to be a high performer for medical applications. Here’s why, and what to expect in the future.
3D-printed resorbable implant technology achieves ISO 13485 certification
Medtech startup BellaSeno (Leipzig, Germany) has obtained ISO 13485 certification for the design and additive manufacturing (aka 3D printing) of resorbable implants. As such, it claims to be among only a handful of companies worldwide to offer integrated contract additive manufacturing of implants under the ISO quality management standard specific to medical devices.
