INTRAVASCULAR STENT
A stent design reduces the likelihood of contact among structural members when the stent diameter is reduced before insertion into the body. In one approach, an undulating link has a J-shaped profile or has an angled portion on one side at the peak of the link, in order to reduce contact during crimping. The stent may also include structural features that improve such aspects as flexibility, the coatibility of a drug coating onto the stent, flare reduction, stent retention within the body and/or reduction of the minimum diameter of the stent during crimping.
ENDOLUMINAL STENT
An endoluminal stent (100) is described herein. In an embodiment, the endoluminal stent (100) includes a plurality of sinusoidal-shaped expandable ringlets (102) provided in parallel to form a tubular structure of the endoluminal stent (100). Further, adjacent ringlets (102) can be connected to each other by one or more asymmetrical offset connectors (108), the offset connectors (108) being non-linear in structure.
IMPLANTABLE GRAFT AND METHODS OF MAKING SAME
The present invention relates to an implantable endoluminal graft comprised of a microporous thin-film metal covering having a plurality of openings and a structural support element underlying and physically attached to the microporous thin-film metal covering, the microporous thin-film metal covering having shape memory properties.
THERMAL PROCESSING OF POLYMER SCAFFOLDS
Methods are disclosed including thermally processing a scaffold to increase the radial strength of the scaffold when the scaffold is deployed from a crimped state to a deployed state such as a nominal deployment diameter. The thermal processing may further maintain or increase the expansion capability of the scaffold when expanded beyond the nominal diameter.
Intravascular stent
An expandable stent for implantation in a body lumen, such as an artery, is disclosed. The stent consists of a plurality of radially expandable cylindrical rings generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting links placed so that the stent is flexible in the longitudinal direction. The link pattern is optimized to enhance longitudinal flexibility and high longitudinal strength compression of the stent.
Methods for treating abnormal growths in the body using a flow reducing implant
A flow reducing implant for reducing blood flow in a blood vessel having a cross sectional dimension, the flow reducing implant comprising a hollow element adapted for placement in the blood vessel defining a flow passage therethrough, said flow passage comprising at least two sections, one with a larger diameter and one with a smaller diameter, wherein said smaller diameter is smaller than a cross section of the blood vessel. A plurality of tabs anchor, generally parallel to the blood vessel wall, are provided in some embodiments of the invention.
Endoluminal prosthesis systems and methods
A stent includes a main body having a plurality of rings that form a helix. Each of the plurality of rings includes a plurality of skewed v-shaped elements that each have a first leg and a second leg that is longer than the first leg. The stent further includes a first end ring and a second end ring positioned to an opposite side of the main body from the first end ring. Each of the plurality of rings of the main body is angled with respect to the first end ring and the second end ring. The stent further includes a first transitional region for connecting the first end ring to the main body, and a second transitional region for connecting the second end ring to the main body.
INTRAVASCULAR STENT

The stent consists of a plurality of radially expandable cylindrical rings generally aligned on a common longitudinal stent axis and interconnected by one or more interconnecting links placed so that the stent is flexible in the longitudinal direction. The link pattern is optimized to enhance longitudinal flexibility and high longitudinal strength compression of the stent.
Balloon catheter with non-deployable stent
An angioplasty balloon including a non-deployable stent to prevent or reduce the potential for slippage of the inflated balloon with respect to the vessel wall being treated. The balloon includes a non-deployable stent that is adapted to be secured to the balloon or angioplasty balloon catheter. The stent has a proximal end, a distal end, and at least three radially-spaced struts, each, each strut connecting the proximal end to the distal end and having one or more bends that allow expansion of the strut to accommodate the inflation of the balloon. The stem is made or a material so that the stent collapses upon deflation of the balloon.
Uniformly Expandable Stent
An intraluminal prosthesis includes a stent architecture having a series of stent elements repeating along a circumferential axis. One series of stent elements includes v-shaped stent elements having at least four different orientations, and V-shaped stent elements connecting adjacent v-shaped stent elements. One series of stent elements includes R-shaped stent elements having at least four different orientations, and U-shaped stent elements having at least two different orientations, the U-shaped stent elements connecting adjacent R-shaped stent elements. Adjacent series of stent elements can be connected by connectors. Portions of the stent elements may narrow in width along a length thereof. The stent architecture may include radiopaque element receiving members. The stent architecture may be formed by machining a metal or polymer tube. The intraluminal prosthesis may include one or more graft layers.
