Abstract
In some examples, an outer jacket of a catheter body comprises a first section that decreases in durometer along a length of the first section in a direction towards a distal end of the catheter body, and a second section more distal than the first section and including the distal end of the catheter body, the second section having a higher durometer than a distal portion of the first section. The second section of the outer jacket and the inner liner define a distal opening of the catheter body that is configured to resist geometric deformation when the distal end of the catheter body is engaged with a guidewire.
