3D Printing a New Type of Airway Stent

3D Printing a New Type of Airway Stent Image Credit: Komsan Loonprom / Shutterstock.com A new type of 3D printed airway stent could make treating upper airway obstructions quicker and safer. Obstruction of central airways and the impairment of airflow that results from it is a major cause of death in surgery, especially for patients suffering from lung cancer, and because of a major rise in this disease, cases of central airway obstruction (CAO) are also on the rise. This narrowing or stenosis of the trachea and the passageways that lead from it to the lungs can be combated through the insertion of a stent to widen the passages and restore airflow.

Global silicon revenues remain stable in 2020

Global silicon revenues remain stable in 2020 According to a new report from the SEMI Silicon Manufacturers Group (SMG), worldwide silicon wafer area shipments increased last year while revenue remained unchanged from 2019 at $11bn. SMG s year-end analysis of the silicon wafer industry reported that silicon shipments totaled 12,407 million square inches (MSI), compared to the11,810 MSI shipped in 2019, a rebound in volume of 5% year over year, recovering close to the historic high set in 2018. â2020 silicon wafer shipment growth was driven by healthy 300mm demand and a strong second half of 2020 despite disruptions to the semiconductor industry caused by COVID-19,â said Neil Weaver, chairman SEMI SMG and vice president, Product Development and Applications Engineering at Shin Etsu Handotai America.

3D-printed bioresorbable airway stent

Date Time 3D-printed bioresorbable airway stent An ETH Zurich research team is using 3D printing to produce a new type of bioresorbable airway stent. This could greatly simplify the future treatment of upper airway obstruction. Narrowing of the trachea or the main bronchi due to injury or illness can end very badly. If patients get too little oxygen, they risk suffocating and often need medical help as quickly as possible. Surgeons insert stents made of medically usable silicone or metal as a way of treating these patients. Although they quickly bring relief, the implants also have disadvantages: Metal stents have to be removed surgically with some effort, which is a burden for the patients, while silicone stents often migrate away from the insertion site. The reason for this is that the implants are not adapted to a patient’s anatomy.

2020 Global Silicon Revenue Remains Stable as Wafer Area Shipments Edge Up Despite COVID-19 Disruption

2020 Global Silicon Revenue Remains Stable as Wafer Area Shipments Edge Up Despite COVID-19 Disruption MILPITAS, Calif., Feb. 2, 2021 /PRNewswire/ Worldwide silicon wafer area shipments in 2020 increased while revenue remained unchanged from 2019 at $11,170 million, the SEMI Silicon Manufacturers Group (SMG) reported in its year-end analysis of the silicon wafer industry. Silicon shipments totaled 12,407 million square inches (MSI), compared to 11,810 MSI shipped in 2019, a rebound in volume of 5% year over year, recovering close to the historic high set in 2018. 2020 silicon wafer shipment growth was driven by healthy 300mm demand and a strong second half of 2020 despite disruptions to the semiconductor industry caused by COVID-19, said Neil Weaver, chairman SEMI SMG and vice president, Product Development and Applications Engineering at Shin Etsu Handotai America.
