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.

Claims

1. A method of delivering a prosthetic device into a lumen of a percutaneous transluminal introducer sheath, comprising:

collapsing the prosthetic device in a lumen of a front-end loading portion;

infusing fluid 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; and

advancing the prosthetic device from the front-end loading portion into the introducer lumen.

2. The method of delivering a prosthetic device to a percutaneous transluminal introducer sheath according to claim 1 further comprising the step of sealing a proximal end of the front-end loading portion lumen prior to said infusing step.

3. The method of delivering a prosthetic device into a percutaneous transluminal introducer sheath according to claim 2 wherein said infusing step includes the step of infusing liquid into the front-end loading portion lumen in a direction perpendicular to the axis of the prosthetic device.

4. The method of delivering a prosthetic device to a percutaneous transluminal introducer sheath recited in claim 1 wherein the prosthetic device includes an umbrella shaped occluder.
