Imaging assembly for intravascular imaging device and related devices, systems and methods

摘要

A method of assembling an intravascular imaging device (102) is provided. In one embodiment, the method includes obtaining a support member having a body portion including a plurality of recesses longitudinally spaced from one another (405); positioning a flex circuit around the support member such that the flex circuit is radially spaced from the body portion of the support member (410); and filling a space between the flex circuit and the support member with a backing material through the plurality of recesses of the body portion (420). In one embodiment, an intravascular imaging device includes a flexible elongate member; an imaging assembly including: a flex circuit; and a support member (330) around which the flex circuit is disposed, the support member having a body portion including plurality of recesses (339), wherein the support member defines lumen in fluid communication with a space between the flex circuit and the support member via the plurality of recesses.
