摘要:
A method for forming strained Si or SiGe on relaxed SiGe on insulator (SGOI) or a SiGe on Si heterostructure is described incorporating growing epitaxial Si1−yGey layers on a semiconductor substrate, smoothing surfaces by Chemo-Mechanical Polishing, bonding two substrates together via thermal treatments and transferring the SiGe layer from one substrate to the other via highly selective etching using SiGe itself as the etch-stop. The transferred SiGe layer may have its upper surface smoothed by CMP for epitaxial deposition of relaxed Si1−yGey, and strained Si1−yGey depending upon composition, strained Si, strained SiC, strained Ge, strained GeC, and strained Si1−yGeyC or a heavily doped layer to make electrical contacts for the SiGe/Si heterojunction diodes.

In a client-server system where a client system presents a browser for user interaction, a browser user interface includes functionality for handling dynamic interface elements received by the browser in connection with received pages, presented as part of the browser user interface and modified in response to selected user input without requiring farther interaction with a server. In addition to, or in place of, dynamic interface elements such as slide sheets, the browser user interface might also include a rotation display area, tool displays that can overlay a page, opaquely or semi-transparently, menu structures, and an ability for the user to modify a page layout without requiring server interaction. The browser might comprise storage for a plurality of rotation display items for storing a summary and a primary presentation for each rotation display item, logic for displaying, by the browser, primary presentations for less all of the plurality of rotation display items in the rotation display area, logic for displaying, by the browser, summaries for items wherein the number of summaries is greater than the number of primary presentations presented at one time, logic for highlighting, among the summaries displayed, the ones of the summaries that correspond to the primary presentations displayed in the rotation display area; and logic for rotating the plurality of rotation display items to display primary presentations for a different subsets of the rotation display items and for updating highlighting of summaries to correspond to the different subsets of rotation display items.
摘要:
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.

Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device, such as a glue gun, that is operably connected to a delivery catheter that can be advanced across a treatment zone in the vein. The delivery catheter can be used to deliver one, two, or more boluses of media (e.g., cyanoacrylate) to occlude the vein along different spaced-apart sections of the treatment zone. External compression can also be applied to the vein by a compression element, such as a hand or multifunctional ultrasound transducer, to occlude portions of the vein along the treatment zone prior to or during the introduction of the boluses of media.

A method includes deploying a fenestration segment stent-graft into a main vessel such that a fenestration section of the fenestration segment stent-graft covers a first branch vessel emanating from the main vessel. The fenestration segment stent-graft includes a proximal section, a distal section, and the fenestration section attached to and between the proximal section and the distal section. The fenestration section has a greater resistance to tearing than the proximal section and the distal section facilitating formation of a collateral opening aligned with the branch vessel in the fenestration section.

A method and device for the treatment of an aneurysm are provided. Different therapeutic agents are delivered to the aneurysmal site by a reservoir and delivery means in a localized, and, in some embodiments, time-released regimen, to treat, limit and reduce the severity of the aneurysm.
摘要:
Methods of treating an aneurysm in a patient in need thereof are provided. The methods comprise delivering to a treatment site an effective amount of a fatty acid inhibitor of a matrix metalloproteinase (MMP) such that the fatty acid inhibitor of the MMP causes the regression of a pre-existing aneurysm. Additionally, an implantable medical device is provided for implanting in a vessel wall of a patient comprising a structural support and a fatty acid inhibitor of an MMP.
