1. An apparatus, comprising:
an intravascular catheter or guidewire configured to obtain intravascular data from a blood vessel of a patient while positioned within the blood vessel,
wherein the intravascular catheter or guidewire comprises:
a first segment;
a second segment; and
a coating separate from and disposed outside of the first segment and the second segment,
wherein the first segment and the second segment are physically distinct components such that the first segment and the second segment are coupled to one another to form a length of the intravascular catheter or guidewire,
wherein the coating extends over a location where the physically distinct components are coupled to one another,
wherein the location is where a proximal portion of the second segment is coupled to a distal portion of the first segment,
wherein the coating forms a seal preventing fluid ingress,
wherein the coating directly contacts an exterior surface of the first segment and an exterior surface of the second segment,
wherein the coating comprises:
a proximal boundary at the first segment;
a distal boundary at the second segment; and
a continuous length between the proximal boundary and the distal boundary, and
wherein the continuous length overlaps the location where the proximal portion of the second segment is coupled to the distal portion of the first segment.
