Abstract
Polymeric tubing, for use with catheters or other medical devices, where the polymeric tubing can have regions of customized properties including, but not limited to, durometer, torque control, flexibility, axial strength, stiffness, etc. One variation of the device allows for transitions between regions to be configured such that there can be gradual or customized transitions between various regions such that the structural characteristics differential between the regions are selectively designed. Additional variations include outer layers having a plurality of material sections extending in a spiral direction along the axial length to form a continuous wall of the outer layer. In certain variations, the structural characteristic differential is minimized or eliminated as compared to conventional catheters.
Claims15
A catheter tubing comprising:
- a tubular body having at least a first axial region and a second axial region;
- a first material section and one or more adjacent materials extending spirally along the first axial region, where the first material section and one or more adjacent materials form an outermost layer of the tubular body in the first axial region;
- and
- a second material section and the one or more adjacent materials extending spirally along the second axial region, where the second material section and the one or more adjacent materials form the outermost layer of the tubular body in the second axial region;
- wherein a first structural property of the first material section is different than a structural property of the one or more adjacent materials and a second structural property of the second material section is different than both the first structural property and the structural property of the one or more adjacent materials.
