A cardiovascular startup company engaged Vention to help develop a steerable device for an embolic protection application in transcatheter aortic valve replacement (TAVR) and other left-heart procedures.
According to the Chief Executive Officer (CEO), embolic protection will play an increasing role in these procedures due to recent changes that have broadened the scope of what is considered a stroke. “Embolic protection is the new frontier in cardiovascular devices,” he said.
One of the challenging design features of this complex device was deploying a self-expanding filter for capturing embolic debris. “It looks like a 4-inch wind sock,” the CEO said. “The filter opens just proximal to the first artery and expands the complete circumference.”
“We didn’t truly understand the mechanics of opening and closing the filter,” the CEO said. “We needed a handle that would be able to do that.”
