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.
Claims13
A method of assembling an imaging probe, the method comprising:
- providing an elongate sheath having an inner lumen and a distal opening;
- inserting, through the distal opening of the elongate sheath, a rotatable conduit and an imaging assembly such that the imaging assembly is connected to a distal end of the rotatable conduit, wherein a lateral extent of the imaging assembly is larger than a diameter of the inner lumen of the elongate sheath, such that the imaging assembly extends from the distal opening of the elongate sheath;
- providing a distal tip having distal end and an open proximal end;
- inserting the distal tip over the imaging assembly, such that the proximal portion of the distal tip contacts and overlaps the elongate sheath over a contact region;
- and
- bonding the distal tip to the elongate sheath, wherein the bonding is performed via a local application of heat over the contact region.
An imaging probe comprising:
- an elongate sheath having an inner lumen and a distal opening;
- a rotatable conduit extending through said inner lumen, said rotatable conduit having an imaging assembly connected to a distal end thereof, wherein a lateral extent of said imaging assembly is larger than a diameter of said inner lumen of said elongate sheath, such that at least a portion of said imaging assembly resides distal to the distal end of said elongate sheath;
- a distal tip housing said imaging assembly, wherein a proximal portion of the distal tip is bonded to a distal region of said elongate sheath.
