Abstract
A catheter may include an elongate body including a proximal portion including a proximal end, and a distal tip portion. The distal tip portion may include an inner liner and a marker band circumferentially surrounding the inner liner. The distal tip portion also may include an outer jacket circumferentially surrounding a first portion of the inner liner and ending proximal of a proximal end of the marker band; and a tip outer jacket circumferentially surrounding a second portion of the inner liner and the marker band. The tip outer jacket extends distally past the marker band distal end to a distal tip of the elongate body, and a proximal end of the tip outer jacket may be laterally adjacent to a distal end of the outer jacket.
