Content Summary
We worked on updating the Extracorporeal Bypass Cannula from its original design, which was a single-use, venovenous cannula with a nitinol basket, reinforced, self-expandable funnel shaped distal tip used during extracorporeal bypass for the removal of undesirable intravascular material.
▪️ The problem: The original Extracorporeal Bypass Cannula device was like a “slinky” and hindered additional navigation to the pulmonary artery.
▪️ The goal: To allow for better use of the device and better navigation to both pulmonary arteries.
▪️ Our process: The HaA team used simulated vasculature models and animal labs to iterate the cannula’s design until it could consistently and easily navigate to both pulmonary arteries. The team also used dual durometer shafts to allow for stability during insertion and flexibility for tight navigational turns.
