1. The document discusses the interaction between microcatheters and guidewires in complex percutaneous coronary interventions (PCI). It describes key components and properties of guidewires and microcatheters that influence their performance as a combination.
2. Effective tip load range is introduced as a measure of how the tip load of a guidewire varies depending on the distance between the microcatheter tip and guidewire tip. Bench test data is presented comparing effective tip load ranges for different guidewire-microcatheter combinations.
3. The combination of a Warrior guidewire with the Turnpike microcatheter is shown to have an effective tip load range of 11.8g to 33.16g,
