Because of its sensitivity to thermal degradation, PLA is difficult to recycle and actually becomes a contaminant in the plastics stream of municipal solid waste. Using the newly discovered process, different grades of PLA can be removed from a stream of commingled plastics and broken down to give high value chemicals. Some of these chemicals, called monomers, can be purified and used as feedstock to synthesize virgin PLA resin.
CAD is the leading cause of death in the United States in both men and women. Treating CAD with bioresorbable vascular scaffolds (BRS) is considered by many to be the “next revolution” in endovascular therapy. This white paper presents the basics of BRS technology, its processing and manufacturing challenges, and its advantages in use with polymer technologies.
Product engineers at catheter manufacturing companies will be only too aware of the problem of delamination – the separation of material layers within the catheter. The solution lay in the design of an additional material layer between the inner etched PTFE liner and the outer jacket material of the catheter. This extra layer would deliver the crucial adhesion required to prevent delamination, ideally without increasing the outer diameter of the finished catheter.
Polyimides (PIs) occupy a particular place in commercial plastics because of their ability to tolerate and function in extremely high temperatures. They are also well known for other beneficial properties including insulating capability, chemical resistance, and excellent mechanical attributes. With their combination of properties and their ability to be tailored toward application specifics, polyimides offer some of best options for performance in high heat and other difficult environments. This white paper provides a brief overview of polymide properties, their structure, and how they are synthesized for use in extreme environment applications.
Have you ever looked closely at an object and thought about how it's made? What are all the steps involved in creating the item from initial design to final production? Maybe you would like to take on the task of getting a product manufactured. There are many aspects to the process of creating a wide variety of products, but they all have something in common at the beginning. You will need to understand this common element because it's the key to a successful design.
Moisture can be harmful to implantable medical devices that operate with electronics. The excess moisture can cause oxidation and dendritic growth in metal parts and wires, and can cause many problems including a fatal electrical shortage or complete device failure as worst case scenarios.
The biocompatibility of silicone is important for medical devices. This article offers a brief overview on the types of silicone that can be used in the different classes of medical devices, the required molding processes, and additional quality considerations.
A common myth is that larger pixel size image sensors are always more sensitive than smaller pixel size image sensors. To explain that this isn’t always the case, this paper will look at the effect that the pixel size has on image quality, especially for the overall sensitivity, which is determined by the quantum efficiency.
The medical device industry is familiar with quality audits, but is less familiar with the benefits of having a cultural audit to assess the competence, dedication, and passion that each party brings to the table.
Collaborating with a lighting expert can help ensure that a medical device’s lighting system is optimized for the instrument design while keeping manufacturing costs down and streamlining the path from product idea to operating room.
