Abstract
An example catheter caliper according to the present disclosure includes a tube having a plurality of markers at predetermined intervals and a wire extending from the tube, wherein the catheter caliper is configured to be received into the vasculature of a patient. Other example catheter calipers and example methods of using the catheter caliper is also disclosed.
Claims20
A catheter caliper assembly, comprising:
- a catheter caliper, including
- a tube having a plurality of radiopaque markers each spaced apart by predetermined intervals;
- and
- a wire extending from the tube, the catheter caliper defined between a distal end of the tube and a proximal end of the wire, wherein the catheter caliper is configured to be received in a vasculature of a patient.
1 more element
A catheter caliper assembly, comprising:
- a catheter caliper, including
- a first component including an outer tube and a first wire extending from the outer tube, the outer tube having a first marker, the first component defined between a distal end of the outer tube and a proximal end of the first wire;
- a second component configured to be received in the outer tube, and defined between a proximal end and a distal end, the distal end having a second marker;
- a ruler arranged at a proximal end of one of the first and second components, the ruler having a plurality of markings each spaced apart by predetermined intervals;
- and
- a pointer arranged at a proximal end of the other of the first and second components, the pointer configured to point to the markings on the ruler.

A method of making intravascular measurements, the method including:
- inserting a catheter caliper into a vasculature of a patient to an artifact or feature to be measured, the catheter caliper including
- a tube having a plurality of radiopaque markers each spaced apart by predetermined intervals, and
- a wire extending from the tube, the catheter caliper defined between a distal end of the tube and a proximal end of the wire;
- and
- measuring the length of the artifact or feature by comparing the length of the artifact or feature to the markers on the tube.

A method of making intravascular measurements, the method including:
- inserting a catheter caliper into a vasculature of a patient to a location near an artifact or feature to be measured, the catheter caliper including
- a first component including an outer tube and a first wire extending from the outer tube, the outer tube having a first marker, the first component defined between a distal end of the outer tube and a proximal end of the first wire;
- a second component configured to be received in the outer tube, and defined between a proximal end and a distal end, the distal end having a second marker;
- a ruler arranged at a proximal end of one of the first and second components, the ruler having a plurality of markings each spaced apart by predetermined intervals, and
- a pointer arranged at a proximal end of the other of the first and second components, the pointer configured to point to the markings on the ruler;
- positioning the distal end of the first and second components past the artifact or feature;
- and
- moving the pointer with respect to the ruler such that the first marker moves with respect to the second marker and the first marker is positioned at a first end of the artifact or feature and the second marker is positioned at a second end of the artifact or feature.
