Results:
• Eight attempts were made per catheter.

• All participants crossed the soft occlusions with both catheters. Two participants failed to cross the hard occlusions using the Seeker (attempts lasted over 10 minutes), while all participants succeeded using the IntraCross catheter.

• The IntraCross catheter took less time to cross the occlusion (mean times: 24 and 23 seconds for soft and hard occlusions, respectively) compared to the Seeker catheter (mean times: 136.25 and 269 seconds, excluding the two failed attempts) (figure 1).

• Overall, the IntraCross catheter consistently succeeded to cross all occlusions, taking an average of 8.35 times faster than the control catheter across the six attempts where both catheters crossed occlusions successfully (figure 1).
