Intravascular imaging catheter

An intravascular imaging device, comprising:

• a catheter shaft including a proximal hypotube section, an imaging window section having a lumen formed therein, and a distal section;
• wherein the distal section includes a dual lumen region and a distal tip region coupled to the dual lumen region;
• a tip member disposed along the distal tip region;
• a marker member disposed adjacent to the tip member;
• wherein the marker member includes first layer, a second layer, and a tie layer disposed between the first layer and the second layer;
• wherein the second layer includes a polymer resin loaded with a radiopaque material;
• and
• an imaging core disposed within the catheter shaft.

A method for imaging a blood vessel, the method comprising:

• disposing an intravascular imaging device within a blood vessel, the intravascular imaging device comprising:
• a catheter shaft including a proximal section and a distal section,
• wherein the distal section includes a dual lumen region and a distal tip region coupled to the dual lumen region,
• a bumper tip member disposed along the distal tip region,
• a marker member disposed adjacent to the bumper tip member,
• wherein the marker member includes an inner layer, a tie layer, and an outer layer including a radiopaque material,
• a sleeve disposed over and coupling the bumper tip member and the marker member, and
• an imaging core disposed within the catheter shaft;
• and
• translating the imaging core relative to the catheter shaft.
