What is Variable Coil and Braid Tubing?
A variable braid or coil tubing is a structure that changes its pattern over the length of the shaft. The PIC or WPI (wraps per inch) can be increased, decreased or shift back and forth.
In order to navigate to vascular regions, many catheters require enhanced rigidity at the proximal end for pushability and torque, and increased flexibility at the distal end. Traditional manual assembly of shaft segments with varying flexibility can be costly and performance can be compromised in bonded regions or at the union of the segments.
Putnam’s Plastics variable flexibility shaft technologies are designed to reduce costs with continuous manufacturing methods and improve product performance by eliminating bonded components.
