Catheter including variable density structural support member

Abstract

In some examples, a catheter includes an elongated body that includes an inner liner, and outer jacket, and a structural support member positioned between at least a portion of the inner liner and the outer jacket. The outer jacket includes a plurality of outer jacket segments in which each outer jacket segment of the plurality is longitudinally adjacent to another outer jacket segment of the plurality. The structural support member includes a first section having a first density, a second section distal to the first section and having a second density, and a third section distal to the second section and having a third density, such that the second density being higher than the first and third densities. The second section of the structural support member is longitudinally aligned with a junction between two outer jacket segments of the plurality of outer jacket segments.
