The finish and quality of Catheters used in minimally invasive surgical procedures play a vital role in its performance with the end user. Several manufacturing dependencies such as the material used along with the extrusion process itself will decide the consistency and repeatability of catheters manufactured across the lifecycle of a catheter.
In this article, we explore the importance of involving extrusion engineers in the earlier catheter development stages.
With scores of decisions to be made in the design and development of a medical device, manufacturers (OEMs) usually rely on their own team of design and development experts. This is great as long as the entire manufacturing process is handled in-house. However, when the manufacturing is outsourced to a contract manufacturer, even very minor differences in how extrusion is conducted will affect the quality and performance of the entire medical device.
The extrusion process uses heat and customized dies to draw the material into a tube form with the desired thickness, diameter and determines important characteristics of the catheter’s performance such as:
Striking the right balance in these properties can determine exactly what kind of catheter you will get, not just once, but on a consistent basis. Only experts in polymer science and experts in the field of materials behavior can work out the right balance in the achieving numerous catheter characteristics
