Abstract
The present disclosure provides for an imaging probe with a rotatable core which allows for rotating imaging assembly that is larger in diameter than the lumen in which the rotatable core resides, as well as methods to construct said probes. The imaging probes are generally elongate flexible imaging catheters for use in cardiovascular procedures. The ability to have a smaller lumen to hold the rotatable core simplifies the inclusion of other functional components to the catheter and may improve the quality of the images produced.
Claims20
An imaging system comprising:
- an imaging probe comprising:
- an elongate hollow sheath having a primary lumen;
- an imaging conduit extending within said primary lumen;
- an imaging assembly mechanically coupled to said imaging conduit at a location remote from a proximal end of said imaging conduit, said imaging conduit configured to deliver energy to said imaging assembly, said imaging assembly comprising a movable member that is moveable relative to said imaging conduit for scanning an imaging energy beam delivered to or generated by said imaging assembly, said movable member comprising a magnet;
- and
- an electrical winding supported by said elongate hollow sheath, said electrical winding surrounding said primary lumen and residing remote from a proximal end of said elongate hollow sheath;
- and
- control and processing hardware residing external to said elongate hollow sheath, said control and processing hardware being in electrical communication with said electrical winding and capable of processing imaging signals associated with reflected imaging energy received by said imaging assembly, said control and processing hardware being further configured to:
- deliver electrical current to said electrical winding such that a magnetic field responsively generated by said electrical winding applies a force to said magnet suitable for scanning the imaging energy beam via motion of said movable member;
- and
- process pose detection signals associated with a pose detection electromagnetic field generated by, or detected by, said electrical winding, to determine a position and/or orientation of a distal region of said elongate hollow sheath.
