The present invention is directed to a stent for use in a bifurcated body lumen having a main branch and a side branch. The stent comprises a radially expandable generally tubular stent body having proximal and distal opposing ends with a body wall having a surface extending therebetween. The surface has a geometrical configuration defining a first pattern, and the first pattern has first pattern struts and connectors arranged in a predetermined configuration. The stent also comprises a branch portion comprised of a second pattern, wherein the branch portion is at least partially detachable from the stent body.

Stent with protruding branch portion for bifurcated vessels

An endoluminal prosthesis system deployable in a region of a patient's vasculature having one or more branch vessels, having a main graft body having a first opening in a wall portion of the main graft body and a pre-loaded guidewire positioned inside the main graft body and advanced through the first opening. One or more branch grafts can be attached to the main graft body to cover one or more openings in the main graft body.

Apparatus and method of placement of a graft or graft system

An endovascular prosthesis includes a tubular body and a mobile external coupling. The tubular body includes a graft material and stents coupled thereto, and forms a lumen therethrough. The mobile external coupling includes a graft material, extends outwardly from the tubular body, and is generally frustoconically shaped. The mobile external coupling includes a base coupled to the tubular body, a top spaced from the tubular body, and a coupling lumen disposed between the base and the top that is in flow communication with the body lumen. An annular support wireform is coupled to the mobile external coupling, and is formed into a sinusoidal configuration having a plurality of opposing first crowns and second crowns, the first crowns of the support wireform extending around of the top of the mobile external coupling. The coupling graft material extending between the second crowns of the support wireform and the tubular body is unsupported.

Mobile external coupling for branch vessel connection

A stent graft is provided which is adapted for being positioned and deployed within a vessel system that includes a main vessel and a branch vessel emanating from the main vessel. The stent graft includes a tubular shaped main body (203) formed from graft material, a branch opening (210) in the graft material of the main body (203) whose position can be varied. A tubular shaped branch graft (205) can extend from the main graft (203). A side wall of the main body (1302) may be configured as a series of connected annular corrugations or pleats (1307), and coupled to the main body to define and provide variable positioning of its branch opening (1310).

Stent graft having a flexible, articulable, and axially compressible branch graft

A stent has a substantially cylindrical tubular body with at least one expandable side branch that has a plurality of members. The plurality of members includes at least one first member having a first width and at least one second member having a second width, where the first width is greater than the second width. Each of the at least one first members and each of the at least one second members define a cell that has at least two stable cell geometries.

Bi-Stable Bifurcated Stent Petal Geometry

A bifurcated stent (10) that uses telescoping rings (41) to support or form the side branch lumen (40) . This design allows the bifurcation branch to extend easily, to a useful distance, and to be deployed along oblique angles. Best of all, this design avoids the need to deploy a bent stent.

Telescoping bifurcated stent

The invention relates to a medical device, such as an intravascular stent, useful for delivering two or more therapeutic agents to a body tissue of a patient at different rates, and methods for making and using such medical device. The medical device includes a substrate and/or coating having a plurality of pores, dispersed in said pores are a plurality of a first and a second therapeutic agents, wherein said first therapeutic agent is bonded to one or more molecule(s) of a first material and the second therapeutic agent bonded to one or more molecule(s) of a second material, such that when the medical device, is in use (e.g., implanted into a body lumen such as a blood vessel), bonded first therapeutic agent is released from the medical device at a rate that is slower than the rate at which the bonded second therapeutic agent is released from the medical device.

Differential drug release from a medical device

The present invention is directed toward a bifurcation stent comprising a plurality of interconnected expansion columns, wherein the plurality of interconntected expansion columns are longitudinally spaced from the proximal end of the stent to the distal end of the stent and wherein the plurality of interconnected expansion columns define a plurality of cells. The inventive stent further comprises a framework defining a side branch cell. The framework is designed to minimize the circumferential space the side branch structure consumes. A plurality of expansion columns are connected to the framework. When the side branch is extended and expanded, the connected expansion columns form the wall of the side branch and the framework expands to conform to the shape of a targeted bodily vessel.

Bifurcated stent with minimally circumferentially projected side branch

A stent (10) comprises a plurality of interconnected framework members defining a plurality of cells. A portion of the interconnected framework members comprise plurality of serpentine bands (20) which comprise connected turns (58) and unconnected turns (55), wherein at least one of the serpentine bands comprises a repeating pattern of three band struts and then five band struts extending between connected turns as the serpentine band is traversed. A portion of the interconnected framework members comprise a side branch structure (60) defining an inner side branch cell that is shaped differently than other cells of the stent. The side branch structure includes a serpentine ring that comprises alternating struts and turns.
