Claim 15:
16. An intravascular ultrasound imaging (IVUS) device, comprising:
a catheter configured to be positioned within a vessel of a patient;
a flex circuit arranged around a longitudinal axis of the catheter to form a cavity, wherein the flex circuit comprises a proximal portion coupled to a distal portion of the catheter;
a plurality of electrical components coupled to the flex circuit adjacent to the cavity; and
a coating extending over a location where the proximal portion of the flex circuit is coupled to the distal portion of the catheter to prevent ingress of fluid into the cavity, wherein the coating is separate from the flex circuit and the catheter, wherein the coating is disposed outside of the flex circuit and the catheter, wherein the coating directly contacts both an exterior surface of the distal portion of the catheter and an exterior surface of the proximal portion of the flex circuit, wherein the coating comprises a proximal boundary at the distal portion of the catheter, a distal boundary at the flex circuit, and a continuous length between the proximal boundary and the distal boundary, wherein the continuous length overlaps the location where the proximal portion of the flex circuit is coupled to the distal portion of the catheter.
