Downhole tools are getting smarter. And while this is great news for users, it’s creating a whole new set of challenges for engineers tasked with designing them and making sure they consistently send critical well information topside. For years, electronics have been incorporated into actuators, sensors and other downhole gear to help identify...
The design of an implantable low-flow pump to treat ascites required an added level of protection against malfunction caused by the potential ingress of moisture, fibrins, large proteins, blood clots, and other organic materials. Steven Twork When engineers at a Swiss medical device company began designing an implantable low-flow pump to treat the...
Systemization reduces time to market. For years, manufacturers of neurostimulators and other active implantables have been feeling extraordinary pressure from shareholders and other funding sources to move more quickly from design stage to production. As a result, many device makers have begun searching for opportunities to integrate components as subsystems in order to...

By Steve Twork Can canted coil springs meet FDA regulatory requirements or OEM cleaning validation standards? This question was posed by a client when we recommended using our spring technology in orthopedic surgical instruments. Typically, OEMs validate and verify components during feasibility testing, but feasibility failures can add cost and offset your project...
When designing orthopedic and medical devices, engineers invariably encounter the same basic challenge: they need to connect two mating surfaces in a repeatable, predictable fashion. While this may sound like a straight-forward task, there are hundreds of different ways to accomplish it. Among the traditional fastening methodologies are ball detents, snap rings, molded...
Why seals alone will not take UHPLC to 20 kpsi and above. Steven Twork, Market Manager for Analytical and Laboratory Automation Products This article advises designers of pumps used in liquid chromatography instruments to look “beyond the seal” for ways to meet industry pressure demands of 20 000 psi and above. It also looks...
Mike Foster, Bal Seal Engineering, Inc. Just like millions of other kids growing up during the mid-l970s heyday of Saturday morning cartoons, I used to watch an animated series called Super Friends. Glued to the tube, bowl of cereal in hand, I would marvel as Superman, Batman, Wonder Woman and a veritable A-list...
