| 20120123517 | DELIVERY SYSTEMS FOR DELIVERING AND DEPLOYING STENT GRAFTS - A delivery system for delivering and deploying a stent graft includes a curved guidewire catheter, an apex release catheter, an apex capture device, a relatively rigid, hollow catheter, and a distal nose. The apex capture device includes a distal capture portion fixedly connected to the distal end of the guidewire catheter and having a distal portion and a proximal stopper having an exposed side facing distally in a plane approximately perpendicular to a longitudinal axis of the curved guidewire catheter. The apex capture device also includes a proximal capture portion fixedly connected to the distal end of the apex release catheter and has fingers extending toward the distal capture portion in a distal direction that define an interior cavity to receive the proximal stopper. The proximal and distal capture portions of the apex capture device define a stent capture state. | 05-17-2012 |
| 20100234932 | SYSTEM AND METHOD FOR DEPLOYING AN ENDOLUMINAL PROSTHESIS AT A SURGICAL SITE - A system for implanting a prosthesis includes a control lumen and a nose cone affixed at a distal end of the control lumen. At least one supporting wire is affixed at one end, is substantially parallel to a major axis of the control lumen and is free at an opposite end, wherein the free end of at least one of the supporting wires is arcuate. Alternatively, a system for implanting a prosthesis includes at least one suture extending from a nose cone affixed to a distal end of a control lumen. The suture extends from the nose cone to a proximal end to a stent graft extending about the control lumen and from the stent graft to a fixed location on the control lumen. The suture is releasable from the stent graft by remote activation, whereby the suture separates from the nose cone to thereby deploy the stent graft. | 09-16-2010 |
| 20100030318 | Dual Capture Device for Stent Graft Delivery System and Method for Capturing a Stent Graft - A delivery system for delivering and deploying stents with proximal and distal apices includes first and second hollow lumens and a hollow apex release lumen, the first lumen having a distal end and an interior extending along a longitudinal axis, the second lumen having a distal end and being slidably disposed about the first lumen, and the apex release lumen having a distal end and being slidably disposed about the second lumen. A proximal apex capture device of the delivery system includes a first distal capture portion fixedly connected to the first lumen, the first distal capture portion having a first distal portion with a proximal end and a proximal stopper having a distal side disposed in a plane approximately perpendicular to the longitudinal axis, being disposed at a first proximal distance from the proximal end of the first distal portion, and defining first stopping surface portions. A first proximal capture portion is fixedly connected to the distal end of the apex release lumen and has fingers extending toward the first distal capture portion in a distal direction, the fingers defining a first interior cavity shaped to receive the first proximal stopper therein, the first distal capture portion and the first proximal capture portion being formed to hold the distal apices there between and, together, defining a first stent captured state in which the first proximal stopper is received in the first interior cavity and the first proximal capture portion approximately closes off the first interior cavity along the longitudinal axis. | 02-04-2010 |
| 20080264102 | Sheath Capture Device for Stent Graft Delivery System and Method for Operating Same - A delivery system for delivering and deploying stent grafts having a proximal stent includes a first lumen and a stent capture device including a capture portion fixedly connected adjacent a first lumen distal end. An outer catheter has a catheter distal end and a catheter inner diameter. A second lumen having a second distal end is slidably disposed about the first lumen and within the outer catheter. A stent graft sheath has a sheath proximal end connected to the second distal end and disposed about the first lumen. The sheath has a sheath distal end and a sheath inner diameter greater than the catheter inner diameter for holding a compressed stent graft. A distal nose cone has a cone proximal end connected to either the capture portion or the first distal end. The nose cone and the capture portion are movably adjustable to selectively capture the sheath distal end therebetween. | 10-30-2008 |
