Abstract
A delivery system for deploying a medical implant includes an elongate delivery wire assembly slidably disposed within a delivery catheter lumen, the delivery wire assembly having an implant loading region configured for seating the implant when the delivery wire assembly is constrained within the delivery catheter lumen and the implant is in a compressed delivery configuration, the delivery wire assembly further including an implant distal protection feature having a central portion coupled to the delivery wire assembly distal of the implant loading region, and a peripheral portion extending proximally from the central portion to at least partially cover a distal end portion of the implant when the delivery wire assembly, implant and implant distal protection feature are constrained within the delivery catheter lumen, wherein the peripheral portion remains extending in the proximal direction when the implant assumes an expanded configuration after being released from the delivery catheter lumen.
