Abstract
A method for percutaneous transluminal front-end delivery of a collapsible prosthetic occluder using a front-end loading portion, a control assembly and an introducer sheath. The prosthetic device is collapsed in a lumen of a front-end loading portion. A valve assembly seals the front-end loading portion lumen proximally of the collapsed occluder. Fluid is then infused through a port extending into the front-end loading portion in communication with the front-end loading portion lumen to remove air bubbles from the collapsed prosthetic device. The prosthetic device is advanced using a control assembly from the front-end loading portion into the introducer and ultimately into the defect site.
