摘要:
Embodiments provide methods and systems for treating aneurysms using filling structures filled with a curable medium. An embodiment of a method comprises positioning at least one double-walled filling structure across the aneurysm and filling the structure(s) with a filling medium so that an outer wall conforms to the inside of the aneurysm and an inner wall forms a generally tubular lumen to provide for blood flow. The lumen is supported with a balloon or other expandable device while and/or after filling. The pressure within the structure and/or in the space between an external wall of the structure and the aneurysm wall is monitored and a flow of the medium into the structure is controlled responsive to the pressure. The pressure can also be used to determine a filling endpoint. The medium is hardened while the lumen remains supported by the balloon. The balloon is then removed after the medium hardens.

Aneurysms are treated by placing a scaffold across an aneurysmal sac to provide a blood flow lumen therethrough. An aneurysmal space surrounding the scaffold is filled with one or more expandable structures which are simultaneously or sequentially expanded to fill the aneurysmal space and reduce the risk of endoluminal leaks and scaffold migration. The expandable structures are typically inflatable and delivered by delivery catheter, optionally with an inflation tube or structure attached to the expandable structure.

Aneurysms are treated by filling at least one double-walled filling structure with a curable medium within the aneurysm. The filling structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. Scaffolds are placed into the tubular lumens in order to help maintain the shape, anchor the filling structures in place, and provide improved blood flow transition into and out of the tubular lumens.

A system for treating an aneurysm in a blood vessel comprises a docking scaffold having with upstream and downstream ends, and a central passageway therebetween. The upstream end engages the blood vessel upstream of the aneurysm. A portion of a first and second scaffolds are slidably received in the central passageway such that an outside surface of the first and second scaffolds engage an inside surface of the docking scaffold. A double-walled filling structure has outer and inner walls and the filling structure is adapted to be filled with a hardenable fluid filling medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a substantially tubular lumen to provide a path for blood flow therethrough. The double-walled filling structure is coupled with at least one of the first and second leg scaffolds in expanded configuration.

Disclosed herein are systems and methods for displaying images and contextually relevant content on a digital content platform, such as a web page. In one embodiment, for example, the systems and methods include: (1) providing a publisher of the image with a reference script for publication with the image, wherein the reference script is a computer-readable instruction that causes an end-user device to call to a content server; and (2) configuring the content server to (a) receive a request for content from the end-user device, (b) identify content that is contextually relevant to the image, (c) deliver the content to the end-user device, and (d) deliver a computer-readable instruction that causes the end-user device to perform an animation that modifies the image and displays the content in a spatial relationship with respect to the image as originally published.

In an first aspect, a ladder for mounting on a vehicle trailer includes an attachment bracket assembly for mounting on the trailer; a first side rail; a second side rail parallel to the first side rail; and a plurality of rungs pivotally connected to both the first and second side rails. The ladder is collapsible to decrease a distance between the first and second side rails. In a second aspect, a ladder for mounting on a vehicle trailer includes an attachment bracket; a first side rail; a second side rail parallel to the first side rail; a plurality of rungs connecting the first and second side rails; and a pivotal connection. The first and second side rails define a plane and the pivotal connection allows for rotation of the plane about a vertical axis. The pivotal connection is disposed between the attachment bracket and the first side rail.

The present invention provides multilayered materials, such as films usable in particular in medical devices in the form of vascular grafts, biocompatible coverings, and/or inflatable bladders, prosthesis for the endoluminal treatment of aneurysms, particularly aortic aneurysms including both abdominal aortic aneurysms (AAA's) and thoracic aortic aneurysms (TAA's).

Printing an electronic document by dynamically creating a destination identifier and transmitting the electronic document with the destination identifier to a destination e-mail address. A server dynamically stores the electronic document with the associated destination identifier and waits to receive the identification-account information from an input device. An agent verifies the inputted identification-account information with the destination identifier stored on the server. The electronic document(s) associated with the destination identifier is then sent to the printer for printing upon verification.
