  • Jacketing Fine Wires: Critical but Challenging

    Because the wires used in neurostimulation and other implantable devices are minuscule and fragile, extruding an insulation layer around them is no easy featSteve MaxsonA polymer jacket is extruded around the fine wires used in such implantable medical devices as neurostimulators, cochlear implants, and guidewires.Among the most difficult and exacting medical device tubing applications is the extrusion of fine-wire jacketing. Although a highly specialized niche process, jacketing fine wires...

    Bundles of hair-thin nitinol enable the fingers of a robotic hand to contract and release.  Brian BuntzDoctoral student Filomena Simone helped develop the hand prototype.Researchers at Saarland University (Saarbrücken, Germany) have developed a lightweight artificial hand capable of carrying out precise motions that uses tiny bundles of nitinol for actuation. The hand is light and flexible, and is devoid of motors, pulleys, pneumatics, or other conventional mechanical components that add...
  • Blood Is No Match for Super-Nonstick Coating

    A super-hydrophobic coating could prove useful for an array of medical device applications.Brian BuntzFor years, Heinz has aired commercials trying to put a positive spin on the way its ketchup stubbornly clings to glass bottles. Plastic bottles make ketchup easier to dispense, but even then, it is seemingly impossible to get all of the ketchup out of the bottle by squeezing or gravity alone. Up to 15% of the condiment remains stuck in the bottle, according to Consumer Reports.Enter a...
  • Achieving More Precise Fluid Dispensing: How Automation Can Help

    A new series of automated fluid dispensing systems combines fast and simple programming to produce better precision.Kristopher SturgisAs medtech devices and components continue to shrink to meet demands, the need for precision has never been greater. While almost half of medical device makers still use manual dispensing technology, the idea of precise liquid dispensing through automation is becoming more  available through Nordson EFD’s new series of automated fluid dispensing systems.The...
