Abstract
Intravascular imaging devices and methods for making and using intravascular imaging devices are disclosed. An example intravascular imaging device may include a catheter shaft assembly including a telescoping assembly and a catheter body. The catheter body may include an imaging window and a distal end region having a first guidewire lumen formed therein. An imaging core may be disposed within the catheter shaft assembly. A distal shaft member may be disposed along an outer surface of the catheter body. The distal shaft member may have a second guidewire lumen formed therein. The intravascular imaging device may also include rod having a first end region coupled to the distal shaft member and a second end region coupled to the telescoping assembly.
Claims20
An intravascular imaging device, comprising:
- a catheter shaft including a first shaft assembly and a second shaft assembly;
- wherein the first shaft assembly includes an intermediate shaft and a distal shaft member attached to the intermediate shaft;
- wherein the second shaft assembly includes an inner shaft and an outer shaft attached to the inner shaft;
- wherein the first shaft assembly is movable relative to the second shaft assembly;
- and
- an imaging core coupled to the first shaft assembly.
An intravascular imaging device, comprising:
- a catheter shaft including a first telescope assembly and a second telescope assembly;
- wherein the first telescope assembly includes an intermediate shaft and a distal shaft member attached to the intermediate shaft;
- wherein the second telescope assembly includes an inner shaft and an outer shaft attached to the inner shaft;
- an imaging core coupled to the first telescope assembly;
- and
- wherein the first telescope assembly is movable relative to the second telescope assembly such that movement of the intermediate shaft results in movement of the imaging core relative to the second telescope 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 including a first shaft assembly and a second shaft assembly,
- wherein the first shaft assembly includes an intermediate shaft and a distal shaft member attached to the intermediate shaft,
- wherein the second shaft assembly includes an inner shaft and an outer shaft attached to the inner shaft,
- wherein the first shaft assembly is movable relative to the second shaft assembly, and
- an imaging core coupled to the first shaft assembly;
- and
- translating the first shaft assembly relative to the second shaft assembly to translate the imaging core relative to the second shaft assembly.
