| 20080228255 | Positionable Stent-Graft Delivery System and Method - A positionable stent-graft delivery system includes a stent-graft, a tip capture mechanism radially constraining a proximal portion of an anchor stent ring of the stent-graft, and a positioning mechanism for positioning the tip capture mechanism. The positioning mechanism includes tensioner guides and cords. To position the tip capture mechanism, a cord is retracted through the respective tensioner guide, e.g., by the physician. Retraction of the cord, in turn, pulls the tip capture mechanism towards a distal end of the tensioner guide. In this manner, the stent-graft is readily repositioned. | 09-18-2008 |
| 20080228256 | Braided Flange Branch Graft for Branch Vessel - A braided flange branch graft formed of a braided super elastic memory material includes a neck between an inner flange and an outer flange. The neck is positioned in a side opening in a sidewall of a main stent graft and the inner flange and outer flange are deployed on opposite sides of the sidewall. The inner flange and the outer flange have a diameter greater than a diameter of the side opening in the sidewall of the main stent graft. Thus, the sidewall of the main stent graft is sandwiched between the inner flange and the outer flange securely and simply mounting the braided flange branch graft to the main stent graft. The braided flange has a substantially unobstructed fluid communication passage therethrough. Further, when stretched into a substantially cylindrical shape for delivery, the braided flange branch graft has a small delivery profile and is extremely flexible. | 09-18-2008 |
| 20080262595 | Methods and Apparatus for Treatment of Aneurysms Adjacent to Branch Arteries - A stent graft includes at least one aperture extending through the main body thereof, into which an extension portion may be deployed for positioning within an adjacent branch flow lumen. The extension portions include self biasing features, wherein the extension is biased into engagement with the main body to seal the interface thereof. Additionally, the extension portion may be configured for tortuous or deviated anatomy, to enable sealing of the extension portion with the body while extending the extension portion in a substantially non-radial direction from the main body. | 10-23-2008 |
| 20090125096 | Stent Graft With Pins - A stent graft with pins, a stent graft including a tubular graft having a perimeter and a central axis; at least one stent ring operably connected about the perimeter, the stent ring having a plurality of struts connected in a sinusoidal pattern, at least one of the plurality of struts having a hole; and a pin having a free end. The pin is secured in the hole with the free end directed outwardly from the central axis. | 05-14-2009 |
| 20100274345 | Self-Flaring Active Fixation Element for a Stent Graft - A stent graft includes a stent graft material of tubular shape and annular shaped stent elements coupled to the stent graft material. The stent graft further includes hooked fixation elements, having hook-end portions and coupling-end, circumferentially spaced about an annular shaped spring attachment element, and coupled to the stent graft at apexes of the spring attachment element. Before deployment the hook-end portions of the apexes of the attachment element and the hooked fixation elements attached thereto are compressed within the space bounded by the interior and exterior sides of the spring attachment element and angled laser cut strut inner surfaces under each apex of the spring attachment element are cut at an angle to cause apex and hook rotation at expansion and deployment. At deployment, the apex and hook-end portions rotate outwardly from the stent graft, partially penetrating the body vessel walls in which the stent graft is deployed and actively fixing the stent graft at the position of deployment. | 10-28-2010 |
| 20110196477 | Methods and Apparatus for Treatment of Aneurysms Adjacent Branch Arteries - A polymer coating/ring is employed to aid in the sealing and connection of modular elements used in body flow lumens for the exclusion and bypass of diseased regions of the flow lumen, such as where aneurysm occurs adjacent to branching blood vessels. | 08-11-2011 |
| 20110251680 | Transcatheter Heart Valve Delivery System With Reduced Area Moment of Inertia - A device for percutaneously repairing a heart valve of a patient including a self-expanding, stented prosthetic heart valve and a delivery system. The delivery system includes delivery sheath slidably receiving an inner shaft forming a coupling structure. A capsule of the delivery sheath includes a distal segment and a proximal segment. An outer diameter of the distal segment is greater than that of the proximal segment. An area moment of inertia of the distal segment can be greater than an area moment of inertia of the proximal segment. Regardless, an axial length of the distal segment is less than the axial length of the prosthesis. In a loaded state, the prosthesis engages the coupling structure and is compressively retained within the capsule. The capsule is unlikely to kink when traversing the patient's vasculature, such as when tracking around the aortic arch, promoting recapturing of the prosthesis. | 10-13-2011 |
| 20110251682 | Transcatheter Prosthetic Heart Valve Delivery System With Funnel Recapturing Feature and Method - A delivery device for percutaneously deploying a stented prosthetic heart valve. The device includes a delivery capsule and a recapture sheath. The capsule is configured to compressively retain the prosthesis. The recapture sheath includes a funnel segment having a plurality of circumferentially spaced runners and a polymer overlay. The runners are attached to a shaft and terminate at a distal tip. The overlay surrounds the runners, and is bonded to the shaft but not to at least the tips. The funnel segment is transitionable from a normal condition to an expanded condition forming a funnel shape with a distally increasing diameter, and self-transitionable back toward the normal condition. The funnel segment facilitates sliding of the capsule over a partially deployed region of the prosthesis as part of a recapturing operation. The runners provide columnar strength, with the overlay controlling a shape of the funnel segment. | 10-13-2011 |
