Diagram 5.

Differences between Ultraflow™ and Marathon™ regarding the soft and nitinol braided distal tip due to the detachment force (A) and the tensile strength (B). A) Comparison of the forces necessary to retrieve the microcatheters out of a cast with a reflux of 3 cm demonstrating that the detachment force in the braided one is 25% less. B) The distal tensile strength is one third greater in the braided one and demonstrates the increase stretch resistance of the distal, soft part of the microcatheter. This allows more tension to be brought to the tip and with it to pull out the catheter with more ease out of the cast.
