Abstract
A system for percutaneous transluminal front-end delivery of a collapsible prosthetic occluder includes a front-end loading portion, a control assembly and an introducer. The front-end loading portion includes a tapering lumen portion and a smaller diameter distal lumen portion. An infusion port communicates with the distal lumen portion immediately adjacent the distal end of the tapering lumen portion. A valve assembly seals the front-end loading portion lumen proximally of the collapsed occluder. The distal end of the front-end loading portion lumen is inserted into the proximal end of an introducer. A control assembly advances the occluder through the front-end loading portion, the introducer and into the defect site.
