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 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 method of reducing bronchial constriction in a subject includes delivering energy to create one or more lesions on a main bronchus so as to transect pulmonary nerves sufficiently to reduce bronchial constriction in a lung of the patient distal to the main bronchus.

System and method for bronchial dilation

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

A catheter and handle assembly for use in treating tissue. More specifically, the invention relates to a catheter assembly having an elongate shaft, ablation assembly coupled to one end of the shaft, and a handle coupled to the other end of the shaft. The handle facilitates both axial and circumferential positioning of the ablation assembly via the shaft in an airway, conduit, or vessel for treatment of the tissue. Embodiments include the use of a handle to facilitate the axial and circumferential positioning of the shaft and ablation assembly through and independent of a working channel of a bronchoscope during treatment for pulmonary disease like COPD and asthma.

Catheter and handle assembly, systems, and methods

L'invention concerne un ballonnet medical expansible ayant au moins un etat statique, un etat deploye et un etat degonfle; le ballonnet medical expansible comprend au moins une zone active comprenant un polymere electroactif.
