Medtech stories we missed this week: Oct. 20, 2017

From InspireMD’s distribution deal to RenalGuard touting a new study, here are seven medtech stories we missed this week but thought were still worth a mention. 1. InspireMD inks Chile distribution deal InspireMD announced in an Oct. 12 press release that it has signed a distribution deal with CorpMedical Chile to distribute the MGuard Prime

What are ball screws?

A ball screw, like a lead screw, converts rotary motion into linear motion. The device consists of a threaded shaft and a ball nut. The latter device rides on the screw, supported by a series of ball bearings that provide a rolling surface rather than the sliding surface of a lead screw. The balls roll

What are leadscrews?

A positioning device without a linear motor is likely to use a leadscrew or a ball screw (discussed in an accompanying section). The leadscrew or power screw is a threaded shaft on which rides a simple threaded nut. It has no ball bearings. Leadscrews use the helix angle of the thread to convert rotary motion

Radiolucent Pedicle Screw System revolutionizes care for cancer patients

icotec AG, an innovative technology company focused on creating and manufacturing new products from Carbon/PEEK composites, revolutionizes spinal care for cancer patients. For spinal tumor treatment, radiation therapy plays an important role in pain management, the local treatment of spinal tumors and the prevention of pathologic fractures. Before administering radiation therapy, the radiologist relies on

How to ensure bolted joint integrity when using a Compression Limiter in a plastic assembly

Compression Limiters are used to protect plastic components in bolted joints and maintain a threaded fastener’s clamp load by eliminating plastic creep. To function properly, bearing surface beneath the bolt’s head must extend over the Compression Limiter to contact the plastic component. Assembly considerations Several factors including speed and assembly method must be considered when

Simple rubber washer prevents shaft collars from getting stuck on shafts

Amacoil has introduced the Elasto-Ring washer for use with U-Clip quick release shaft collars. Elasto-Ring installs by hand with no tools required and assures easy removal of the U-Clip collar. Amacoil is the exclusive U.S. distributor for Elasto-Ring washers, Uhing U-Clip and EasyLock shaft collars and for Uhing rolling ring traverse drives. When a U-Clip

Fit-LINE’s GrabLOC double containment fittings engineered for demanding fluid processing applications

To create leak-free fitting assemblies for demanding bulk-chemical delivery applications, Fit-LINE introduces GrabLOC double containment fittings for terminating and non-terminating installations. Fit-LINE, a fittings supplier to the Semiconductor, Biotech, Pharmaceutical and Ultra-Pure Water industries, focused the company’s over 20 years of fluoropolymer injection molding and fitting expertise to create GrabLOC fittings. GrabLOC non-terminating double containment

SPIROL introduces 316 stainless steel coiled spring pins

SPIROL International Corporation is pleased to introduce a line of 316 stainless steel Coiled Spring Pins designed for applications used in highly corrosive environments. Easily recognized by its unique 2¼-coil cross-section, Coiled Spring Pins are self-retaining pins that compress when installed into the host component. They are the only pins with uniform strength and flexibility

Solving Assembly Challenges in Reduced Footprint Applications

Smaller, lighter, and thinner electronic devices and their inherently restrictive design envelopes present several challenges on the road to  their assembly and manufacture. Hardware for component attachment must perform reliably, despite the shrinking and limited footprints for fastener placement and installation. In addition, designers face reduced parts counts for weight savings and production economies. An entirely

The CNC Shrinks from Industrial Size to Individual Size

Like various smaller sized rapid prototyping equipment and 3D printers, the CNC is following suit and shrinking to a “personal” size. The design concessions necessary to achieve that size are fewer than you might think. The term ‘Personal CNC’ describes the new Tormach mill and correlates to the first personal computers when they shrank in

Biocompatible Implantable Contacts Set a New Pace

In many implantable medical devices, implantable contacts made from biocompatible materials are replacing traditional methods. For example, ImplanTac socket contacts from Hypertronics are being used in pacemakers to replace set-screws that mechanically connect the lead to the pacemaker. According to Tom Kannally, Medical Industry Manager, Hypertronics, set-screws depend upon the amount of torque the surgeon
