1. A catheter comprising:

  • an elongated body extending between a proximal end and a distal end, the elongated body comprising;

    an inner liner defining an inner lumen of the elongated body;

    an outer jacket; and

    a structural support member positioned between at least a portion of the inner liner and the outer jacket, wherein the outer jacket comprises;

    a first section decreasing in durometer along a length of the first section in a direction towards the distal end of the elongated body; and

    a second section more distal than the first section and including the distal end of the elongated body, the second section having a higher durometer than a distal portion of the first section, wherein the second section and the inner liner define a distal opening of the elongated body configured to resist geometric deformation when the distal end of the elongated body is engaged with a guidewire.
