System for the percutaneous transluminal front-end loading delivery of a prosthetic occluder
First Claim
1. A front-end loading delivery device for transluminal delivery of a collapsible prosthetic occluder, comprising:
- a front-end loading portion comprising a main body having a distal end, a proximal end and a lumen extending therethrough, a portion of said lumen being tapered inwardly toward a smaller diameter distal portion;
an infusion port extending through said main body and in direct communication with said distal portion of said lumen;
a valve for sealing said lumen proximally of said small diameter distal portion; and
a control assembly comprising;
an elongated shaft having a proximal end, a flexible distal end and a lumen extending therethrough;
a locking wire extending through said lumen of said elongated shaft having a proximal end and a locking member at a distal end which is extendable beyond said flexible distal end of said elongated shaft;
a portion of said flexible distal end of said elongated shaft being adapted to lockingly hold said locking member and a locking member of a collapsible prosthetic occluder.

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.
