Filed:

Nov 15, 2002

Appl. No.:

10/295454

Inventors:

Orla McCullagh - Waltham MA, US
William R. Quinn - Swampscott MA, US

Assignee:

Scimed Life Systems, Inc. - Maple Grove MN

International Classification:

A61F 2/06

US Classification:

623 153

Abstract:

A stent and method for making the stent are provided. The stent comprises regions of differing numbers of braided filaments to provide a stent with different dimensions and/or properties in different regions along the stent length. A preferred stent comprises a first and second plurality of braided filaments each braided together. The second plurality of braided filaments is braided into the first plurality of braided filaments to form a region of different properties than the first. A preferred embodiment is a stent having a narrower diameter along a more flexible region and a broader diameter along a more rigid region. Also included is a method of constructing a braided stent in accordance with the above. The method comprises the steps of braiding a first plurality of filaments to form the flexible portion, combining a second plurality of filaments to the first plurality of filaments, and then braiding the second plurality of filaments with the first plurality of filaments to form the more rigid region from the combination of the first and second plurality of filaments, wherein the second plurality of filaments are braided only in the rigid region.

US Classification:

623 128, 623 113

Abstract:

A composite multilayer implantable material having a first inner tubular layer formed of expanded polytetrafluoroethyene having a porous microstructure defined by nodes interconnected by fibrils, wherein said first layer has a plurality of pleated folds, a second tubular layer formed of textile material circumferentially disposed exteriorly to said first layer; and having an elastomeric bonding agent applied to one of said first layer or second layer and disposed within the pores of said microstructure for securing said first layer to said second layer.

International Classification:

US Classification:

623 113, 623 135

Abstract:

A stent-graft comprising a stent and a graft having a supported portion lining or covering at least a portion of the stent, and an unsupported portion extending proximally beyond the proximal end of the stent. The stent-graft may have a length corresponding to at least a mean standard length from a standard incision point to a distal-most portion of a standard lumen into which the distal end of the stent is adapted to be deployed, with the unsupported portion of the graft extending beyond the mean standard length by an amount equal to at least two, if not three or more, standard deviations of the mean standard length. A method for deploying the stent-graft comprises making an incision in a wall of the lumen, introducing and deploying the stent-graft in the lumen so that the proximal end extends beyond the incision, and attaching the graft to a lumen by anastamosis.

Abstract:

A system and method for uniform deposition of material layers on wafers in a rotating disk chemical vapor deposition reaction system is provided, wherein one or more substrates are rotated on a carrier about an axis while maintaining surfaces of the one or more substrates substantially perpendicular to the axis of rotation and facing in an upstream direction along the axis of rotation. During rotating a first gas is discharged in the downstream direction towards the one or more substrates from a first set of gas inlets. A second gas is discharged in the downstream direction towards the one or more substrates from at least one movable gas injector, and the at least one movable gas inlet is moved with a component of motion in a radial direction towards or away from the axis of rotation.

Abstract:

Described is a method for sharing a portion of a sharer display with a viewer display. A sharing area that defines the portion of the sharer display to be shown on the viewer display is determined in response to a display allocation of the viewer display and a cursor position in the sharer display. Display data within the sharing area is provided to a viewing computer for presentation on the viewer display. As changes in the position of the cursor in the sharer display are detected, the sharing area is moved to define a different portion of the sharer display and the viewers are presented with new shared display data. The method optionally includes showing a sharing frame on the sharer display to indicate the perimeter of the portion of the sharer display showing on the viewer display.
