Abstract

Cut-pattern designs creating a frame structure from a solid tube, which may be used as a portion of medical device, such as a catheter. The tube includes a plurality of units of cutout segments which are distributed in band around a circumference of the tube. A tube can have multiple different zones, each having units with varying cutout segments. The cutout segments can have varying cutout surface area allowing the flexibility of the tube to be modified at any point along the tube by altering the cutout surface area with zones having greater cutout surface areas as compared to another zone are more flexible. The tube can be incorporated into a catheter.
