Why PEEK is so hard to extrude

PEEK — a popular material for catheters and minimally invasive tubing — can trip up novices when it comes to extrusion. Polyetheretherketone (PEEK) is known throughout the medical device industry for its toughness, strength and high heat thermal characteristics. It’s often used to replace metal components in medical devices; because it’s a thermoplastic it can be injection-molded

MD&M West: 10 technologies you should know

MD&M West is one of the largest medical device manufacturing events in the world, so it’s easy to get lost on the show floor. Even if you were in Anaheim, Calif., for the event last week, you may have missed a lot. From a new robotics insights display from Rethink Robotics to a disinfectant-resistant plastic

Could this Eastman polymer improve medical device housing durability?

Specialty plastics provider Eastman used the recent MD&M West to tout the ability of its MXF221 copolyester to hold up to repeated application of hospital disinfectants. Eastman officials think MXF221 could be a new option for medical device manufacturers – especially because a cracked housing could endanger the electronics inside expensive equipment including ultrasound and

Dow touts versatility in latest LSR grades for overmolding

Dow Medical Solutions, a business unit of the DowDuPont Specialty Products Division has introduced two new liquid silicone rubber (LSR) technologies to support a broader range of rigid plastic substrates for overmolding applications. These new elastomeric products give designers and manufacturers greater options for creating differentiated devices with improved safety and durability. The two grades include

Secant Group officials think they’ve cracked vascular regeneration: Here’s how

Secant Group today announced what it described as game-changing technology to advance vascular regeneration, solving problems that surgeons presently have when it comes to vascular harvesting and the non-resorbable synthetic graft compliance mismatching. The technology, which Secant (Telford, Pa.) developed in partnership with its sister company SanaVita Medical, involves a synthetic small bore vessel with a hollow

Tiny hair-like fibers help create interconnections between brain regions

MIT researchers have used a single flexible fiber about the size of human hair to deliver optical, electrical and chemical signals back and forth into the brain to create an improved way of learning about the functions and interconnections of different brain regions. The fibers replicate the softness and flexibility of brain tissue which allows

Teleflex Medical launches new suture technology to reduce tissue strangulation

Teleflex Medical has created a new suture technology that may reduce tissue strangulation and a cutting effect in situations where tissue pull-through is a risk. The technology, called Force Fiber Fusion, is a two-in-one construct that goes from a round suture to a flat braid center segment and back to round suture. It is made

This artificial cartilage is made using material from bulletproof vests

The same Kevlar material that is used to make bulletproof vests, jackets and gloves now has the potential to make artificial cartilage that could be implanted in the body. Kevlartilage – a material developed at the University of Michigan and Jiangnan University – can withstand just as much force as the cartilage in the human

PEEK formulations for new implantable devices

Since the late 1990s, polyether ether ketone has become a go-to material for companies that manufacture orthopedic implants, thanks to its radiolucency and anatomical properties. Now, custom formulations of PEEK are enabling new potential applications for the polymer. Lawrence Acquarulo, Foster Corp. Polymers have always played a role in modern implantable medical devices. But until

Biomaterials: Is there a better way for FDA to regulate them?

The medical device industry is pretty conservative when it comes to materials used in medical devices. That begs the question: Do we need a new FDA approval pathway for biomaterials? Mike Drues thinks the answer is “yes.” “It really will encourage companies to use new materials and not be hamstrung with materials that have been
