Abstract
An imaging catheter is provided. In one embodiment, the imaging catheter includes a flexible elongate member that includes a proximal portion formed of a first material embedded with a first braid with a first braid pitch; a distal portion formed of a second material embedded with a second braid with a second braid pitch, wherein the second material is a lower durometer than the first material and wherein the second braid pitch is a higher per inch count than the first braid pitch such that the distal portion is more flexible than the proximal portion; a primary lumen extending between the proximal portion and the distal portion; and a plurality of secondary lumens extending between the proximal portion and the distal portion; and an imaging component coupled to the distal portion of the flexible elongate member.
