OCCLUSION-CROSSING DEVICES, IMAGING, AND ATHERECTOMY DEVICES

摘要

A catheter device for crossing occlusions includes an elongate body, a central lumen extending within the elongate body from the proximal end to the distal end, a rotatable tip at the distal end of the elongate body, and an OCT imaging sensor. The rotatable tip is configured to rotate relative to the elongate body. The OCT imaging sensor includes an optical fiber coupled with the rotatable tip and configured to rotate therewith. A distal end of the elongate body includes one or more markers configured to occlude the OCT imaging sensor as it rotates. A fixed jog in the elongate body proximal to the distal end of the catheter positions the distal end of the catheter at an angle relative to the region of the catheter proximal to the fixed jog and is aligned with the one or more markers on the elongate body.

1. A catheter device for crossing occlusions, the device comprising:
an elongate body; a central lumen extending within the elongate body from a proximal end of the elongate body to a distal end of the elongate body; a rotatable tip at the distal end of the elongate body and configured to rotate relative to the elongate body; an OCT imaging sensor comprising an optical fiber coupled with the rotatable tip and configured to rotate therewith, wherein the distal end of the elongate body comprises one or more markers configured to occlude the OCT imaging sensor as it rotates; and a fixed jog in the elongate body proximal to the distal end of the catheter, the fixed jog positioning the distal end of the catheter at an angle relative to the region of the catheter proximal to the fixed jog, and wherein the fixed jog is aligned with the one or more markers on the elongate body.
