  • GUIDEWIRE DIRECTIONAL POSITIONING AND RE-ENTRY CATHETER WITH ROTATIONAL INDICIA
    Publication number: 20260263742
    Abstract: A multi-lumen catheter to perform re-entry of a body lumen to bypass an intraluminal lesion includes rotational indicia to permit the determination of catheter and/or guidewire orientation via external imaging, such as a fluoroscopy system.

  • Systems, devices and methods for antegrade dissection and reentry
    Patent number: 12685445
    Abstract: An exemplary catheter includes a housing having the distal catheter region configured to be at least partially disposed in a body and the proximal catheter region configured to remain at least partially outside of the body. The catheter may define an imaging lumen configured to receive an imaging device, a guidewire lumen, an off-ramp, and an indicator lumen configured to receive an indicator that is detectable by the imaging device. The guidewire lumen is configured to receive a guidewire and includes a distal region and a proximal region. The off-ramp extends from the guidewire lumen at or near an intersection of the distal and proximal regions of the guidewire lumen. The catheter may also include one or more guidewire feeders configured to cause the guidewire to move from the proximal section to the off-ramp.
