Abstract
An implant system may include a delivery sheath having an actuator mechanism, an anchoring assistance device including an expandable scaffold including a mid-body section, a cusp interface section, and a crown end arrangement, and a replacement heart valve implant. The cusp interface section includes a plurality of loop portions arranged at radial intervals about the expandable scaffold. Each loop portion is circumferentially spaced apart from another loop portion by a region having a deployment ring, the region being configured to span a commissure of the aortic valve and extending distally a shorter distance from the distal end than the loop portions. An elongate deployment member is configured to releasably engage with the deployment rings to actuate the expandable scaffold from a delivery configuration to a deployed configuration. The replacement heart valve implant is configured to be at least partially disposed within the expandable scaffold in the deployed configuration.
