Composite Tubing

Polygon, Walkerton, IN, has released a high-performance composite tubing for surgical applications. PolyMed® composite tubing is ideal for use in a diverse array of medical applications such as placement on electrosurgical devices (both monopolar and bipolar), surgical ablation tools, and suction irrigation or trocar cannula. Lightweight and strong, the tubing is invisible to x-ray. It is thermally insulating and nonconductive. It acts as a drop-in replacement for stainless steel tubing in a variety of endoscopic and laparoscopic instrumentation applications. It is ISO-10993 compliant and can be sterilized.

Closed-Loop System

Nordson ASYMTEK, Carlsbad, CA, has released a closed-loop flow control that automatically compensates for viscosity changes during conformal coating. Qadence selectively applies coating to specific areas of a circuit board consistently throughout production. The flow control system maintains stable fluid application, flow rates, and performance by automatically compensating for viscosity changes related to temperature, humidity, and batch-to-batch variation. It eliminates the need for frequent operator adjustments and downtime to recalibrate the process.

Chipset

Chipsets from THine, Tokyo, Japan, enables high-quality video performance for a wide range of applications. The new THCV241A and THCV242 chipsets allow engineers to extend MIPI CSI-2 transmission from 1 ft to over 15 m. Because the 241A/242 chips support video mirroring, this chipset can be used for troubleshooting system problems or for applications such as 3D surgical equipment, which require a secondary application processor that is distant from the source video camera.
