Abstract
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 Analysis
Total Claims: 5
Claim 1
Independent Claim
71 words
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.
Claim 2
Independent Claim
71 words
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.
Claim 3
Dependent Claim
37 words
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.
Claim 4
Dependent Claim
44 words
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.
Claim 5
Dependent Claim
26 words
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.
