Abstract
Intravascular imaging devices as well as methods for making and using intravascular imaging devices are disclosed. An intravascular imaging device, may include a catheter shaft assembly including a telescoping assembly and a catheter body. The catheter body may include a hypotube region, an imaging window region, and a distal end region having a guidewire lumen formed therein. At least a portion of the hypotube region may have a plurality of slots formed therein. An imaging core may be disposed within the catheter shaft assembly.
Claims20
An intravascular imaging device, comprising:
- a catheter shaft assembly including a telescoping assembly and a catheter body;
- wherein the catheter body includes a hypotube region, an imaging window region, and a distal end region having a guidewire lumen formed therein;
- wherein the imaging window region and the hypotube region are coupled together at an overlapping joint;
- wherein at least a portion of the hypotube region has a plurality of slots formed therein;
- wherein the plurality of slots includes a first group of two or more slots disposed at a first axial location and a second group of two or more slots disposed at a second axial location spaced apart from the first axial location;
- and
- an imaging core disposed within the catheter shaft assembly.
An intravascular imaging device, comprising:
- a catheter shaft assembly including a telescoping assembly and a catheter body;
- wherein the catheter body includes a hypotube attached to the telescoping region, an imaging window region extending distally from the hypotube, and a distal end region having a guidewire lumen formed therein;
- wherein a proximal end region of the imaging window region overlaps with a distal end region of the hypotube;
- wherein the hypotube has a distal region having plurality of slots formed therein and a proximal region free from slots;
- 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 assembly and a catheter body,
- wherein the catheter body includes a hypotube attached to the telescoping region, an imaging window region extending distally from the hypotube, and a distal end region having a guidewire lumen formed therein,
- wherein the hypotube has a distal region having plurality of slots formed therein and a proximal region free from slots,
- wherein a proximal end region of the imaging window region overlaps with the distal region of the hypotube, and
- an imaging core disposed within the catheter shaft assembly;
- and
- translating the imaging core relative to the catheter shaft.
