1. A catheter comprising:
an elongate body comprising:
a proximal portion including a proximal end of the elongate body; and
a distal tip portion, wherein the distal tip portion comprises:
an inner liner;
a reinforcement member circumferentially surrounding the inner liner;
at least one marker band circumferentially surrounding the inner liner, each marker band of the at least one marker band extending from a respective marker band proximal end to a respective marker band distal end;
an outer jacket circumferentially surrounding a first portion of the inner liner and ending proximal of a proximal-most marker band proximal end; and
a tip outer jacket circumferentially surrounding a second portion of the inner liner and the at least one marker band, including proximal and distal ends of the at least one marker band, wherein the tip outer jacket extends distally past a distal-most marker band distal end to a distal tip of the elongate body and extends proximal to the proximal-most marker band proximal end, wherein a proximal end of the tip outer jacket is laterally adjacent to a distal end of the outer jacket, wherein the tip outer jacket exhibits a lower durometer than the outer jacket, and wherein the elongate body defines at least one lumen extending from adjacent to or at the proximal end of the elongate body to adjacent to or at the distal tip; and
an elongate push member, wherein the elongate push member is mechanically coupled to the proximal end of the elongate body, wherein a distalmost edge of the elongate push member contacts a proximal end of the reinforcement member, and wherein the elongate push member has a lower profile than the elongate body.
