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.
Claims27
A medical tubing comprising:
- a tubular body having an axis extending lengthwise, the tubular body having a first region and a second region both extending along the axis and both having a wall formed from a plurality of material sections that extend spirally along the axis;
- the plurality of material sections including a reinforcement material section that extends in a continuous spiral over the first region and over the second region;
- and
- wherein the reinforcement material section comprises a first hardness in the first region and a second hardness in the second region, where the first hardness is different than the second hardness.
A medical tubing comprising:
- a tubular body having a first region adjacent to a second region each extending along an axial length of the tubular body;
- and
- a plurality of material sections extending spirally along the axial length at least partially forming a wall of the first region and the second region of the tubular body;
- wherein in the first region, each of the plurality of material sections comprises a first polymer that extends spirally where the first polymer comprises a first hardness;
- wherein at the second region at least one of the plurality of material sections comprises one or more polymers having a second hardness less than the first hardness.
