Intravascular imaging devices

An intravascular imaging device, comprising:

• a catheter shaft assembly including a telescoping region and a catheter shaft extending distally therefrom;
• wherein the catheter shaft includes an imaging window region and a distal tip region having a guidewire lumen formed therein;
• wherein the distal tip region has a first portion disposed distally of the imaging window region and a second portion disposed along a side surface of the imaging window region;
• and
• an imaging core disposed within the catheter shaft assembly.

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 assembly including a telescoping region and a catheter shaft extending distally therefrom,
• wherein the catheter shaft includes an imaging window region and a distal tip region having a guidewire lumen formed therein,
• wherein the distal tip region has a first portion disposed distally of the imaging window region and a second portion disposed along a side surface of the imaging window region, and
• an imaging core disposed within the catheter shaft assembly;
• and
• translating the imaging core relative to the catheter shaft assembly.
