There is one polymer-based processing technology that can achieve both flexibility and pushability along a catheter shaft without the multiple materials and steps – polymer solution casting. This manufacturing option utilizes liquid polymer layers to encapsulate multiple components or wire reinforcements, and vary wall thicknesses or diameters along the length of the device, while also maintaining tight tolerances.

“The polymer solution casting technology offers a level of precision and control in catheter fabrication that is truly revolutionary. Conventional reflowing of polymers falls short of being able to achieve this level of control and as such, limits catheter performance from being fully realized,” offers Stephen Griffin of Griffin BioMedical.
