Abstract: Stent delivery systems, including self-expanding stent delivery systems, and methods for making and using the same. A self-expanding stent delivery system may include an inner member. An outer sheath may be slidably disposed about the inner member. A self-expanding stent may be disposed between the inner member and the outer sheath. A rolling membrane may be attached to the outer sheath and to the inner member. A lubricious component may be disposed adjacent the outer sheath for reducing friction between the outer sheath and the membrane.

Abstract: A stent comprises a plurality of serpentine circumferential bands and a plurality of connector columns. Each connector column is located between two adjacent serpentine circumferential bands and comprises a plurality connector struts. Each connector strut is connected at one end to one serpentine circumferential band and at another end to another serpentine circumferential band. Each connector strut has step sections and at least one riser. Each step section extends substantially in a circumferential direction and each riser extends in a substantially longitudinal direction. The steps in a connector are connected to one another via a riser.

Abstract: Medical devices that include micromachined hypotubes or that have themselves been micromachined can provide advantages in flexibility, strength and other desirable properties. Examples of such medical devices may include catheters such as guide catheters and balloon catheters. Such devices may also include dual shaft medical devices in which an outer shaft is reversibly lockable onto an inner shaft.

Abstract: A bifurcated stent has an expanded and an unexpanded state with an outer surface and an inner surface with a wall extending there between and the inner surface defining an inner stent lumen. The stent has a primary stent body with a proximal end and a distal end with a band circumferential there between. A side branch portion is disposed in the band circumferential and in the unexpanded state the band circumferential has at least one overlapped section such that the at least one overlapped section has a greater density of stent material than the rest of the stent. In the expanded state the side branch portion extends obliquely from the primary stent body.

Abstract: A stent comprises a plurality of serpentine bands. Each serpentine band has alternating peak regions and trough regions and extends about substantially the entire circumference of the stent. At least one of the serpentine bands has a spline extending therefrom toward a serpentine band adjacent thereto. Serpentine bands which are adjacent one another are connected one to the other.

Abstract: Medical devices, such as endoprosthesiss, and methods of making the devices are disclosed. In some embodiments, a endoprosthesis includes at least three layers, each of the layers comprising approximately one grain or more across a thickness of the layer.

Abstract: In one embodiment of the invention, a stent may be provided comprising a first undulating band comprising a series of alternating first peaks and first troughs and a second undulating band comprising a series of alternating second peaks and second troughs. The first undulating band has a first wavelength and a first amplitude and the second undulating band has a second wavelength and a second amplitude where the second amplitude is different from the first amplitude and the second wavelength is different from the first wavelength. A plurality of longitudinally oriented first connectors extend between the first peaks and second peaks.

Abstract: A catheter assembly of the type having at least two balloon catheters extending from a proximal end of the assembly to a distal end of the assembly. At least a portion of the assembly having a cross-sectional profile having a cross-sectional profile which is substantially circular in shape.

Abstract: Devices and methods for managing a portion of an intravascular catheter which is extending from the body of a patient under operating room conditions (e.g., while a physician is wearing surgical gloves). A catheter in accordance with one embodiment of the present invention includes a catheter shaft having a proximal end and a distal end, and a keeper fixed to the catheter proximate a proximal end thereof The keeper includes one or more inside surfaces defining a channel which is adapted to entrap a straight portion of the catheter shaft. The keeper also includes a passageway which is adapted to allow a curved portion of the catheter to pass into the channel of the keeper.

Abstract: A catheter assembly of the type having at least two balloon catheters extending from a proximal end of the assembly to a distal end of the assembly. At least a portion of the assembly having a cross-sectional profile having a cross-sectional profile which is substantially circular in shape.
