"WAND-SEEKER" Chronic occlusion re-entry device




In the reverse CART technique, a catheter and a wire are positioned on opposite sides of the coronary occlusion. Through different manipulation of the catheter and the wire, the wire is, ultimately, aligned with the tip of the antegrade catheter, crosses the occluded coronary segment, and gets “externalized” converting a CTO in a regular PCI. Unfortunately, it can be difficult to align and cross the retrograde wire into the antegrade catheter tip.


New Device Features


The new device and system can facilitate the alignment, crossing and wire re-entry in the antegrade guiding catheter with reduction in time, radiation exposure for the patient/operator, risk of coronary perforation, and the need for “investment procedure”. The new technology uses a guiding catheter having a magnetic distal tip and a crossing wire having a ferromagnetic tip. When the guiding catheter is positioned on one side of the occlusion (e.g., the antegrade side) and the crossing wire is positioned on the opposite side of the occlusion (e.g., the retrograde side), the crossing wire can be passed through or around the occlusion toward the guiding catheter. The presence of the magnetic field generated at the tip of via antegrade catheter will bias the tip of the wire toward the tip of the antegrade catheter. This magnetic field will provide additional magnetic bias to the tactile and visual feedbacks commonly utilized in retrograde crossing of a coronary occlusion.


Potential Advantages


1. Increase success rate in re-CART

2. Reduced procedural time/ radiation exposure for the patient/operator

3. Reduced risk of perforation of the coronary artery

4. Alternative device/mechanism to existing re-entry devices


Potential Applications


• Coronary Procedures, including sub-intimal space application

• Vascular Procedures, including peripheral
