A system for percutaneous transluminal front-end delivery and retrieval of a collapsible prosthetic occluder includes a front-end loading portion, a control assembly and an introducer and retrieval sheath assembly. 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 and retrieval sheath assembly. A control assembly advances the occluder through the front-end loading portion, the introducer and retrieval sheath assembly and into the defect site. The retrieval sheath assembly is less flexible than the introducer sheath and is sufficiently rigid to evert the deployed occluder when retracted thereagainst.

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.

An occlusion device for percutaneous transluminal correction of intracardiac and vascular septal defects is disclosed. The device comprises a pair of opposed occluders that are connected to one another using an interconnection that allows the occluders to move relative to one another. Additionally, a means for fluoroscopically visualizing and distinguishing the individual occluders of the device is also disclosed.

Occluder and method for repair of cardiac and vascular defects

A device for the percutaneous transluminal repair of septal defects is disclosed. The device comprises first and second expandable occluders fastened to each other, each occluder including a framework having a central hub with elongated struts radiating therefrom. The struts are constructed such that they have a resistance to fatigue that exceeds the maximum fatigue stresses to which the struts will be subjected over a prolonged period in vivo. As such, the device exhibits a significantly decreased likelihood of metal fatigue failures after prolonged exposure in vivo.
