Catheters and devices and systems incorporating such catheters

A catheter, comprising:

• a sheath defining a lumen, the sheath having a proximal end, a distal end, and a transition portion between the proximal end and the distal end;
• a reinforcing structure surrounding the lumen;
• and
• a plurality of corrugations disposed only in the transition portion and the distal end, wherein a depth of at last one corrugation in the transition portion is less than a depth of at least one corrugation in the distal end.

A catheter, comprising:

• a sheath defining a lumen and including a plurality of corrugations, the sheath including:
• an inner liner, and
• a jacket surrounding the inner liner;
• and
• a reinforcing structure surrounding the lumen,
• wherein a width of at least one corrugation of the plurality of corrugations is at least 20% of a thickness of the jacket.

A catheter, comprising:

• a sheath defining a lumen and including a plurality of corrugations;
• and
• a reinforcing structure surrounding the lumen,
• wherein a depth of each of the plurality of corrugations is a distance between a peak and a valley of each of the plurality of corrugations, and the depth of at least one corrugation of the plurality of corrugations at a distal end of the sheath is at least 50% of a thickness of the sheath, and
• wherein the thickness is a distance between a radially outermost surface of the sheath and a radially innermost surface of the sheath.
