Side branch stent
First Claim
Patent Images
1. A medical device comprising:
- a first stent, the first stent comprising a distal end, a proximal end, and an opening extending from the distal end to the proximal end along an axis, wherein the first stent is expandable from a contracted state to an expanded state; and
a first expansion column, the first expansion column comprising a first end, a second end, a width defined by the distance between the first end and the second end and an opening having a diameter, the opening extending from the first end to the second end along an axis, wherein the first expansion column is expandable from a contracted state to an expanded state, wherein the first expansion column is connected to the proximal end of the first stent and the axis of the at least one expansion column is at an angle relative to the axis of the first stent and wherein the first expansion column is deformable from and/or into a flattened configuration, such that, when in the flattened configuration, portions that make up the first end of the first expansion column are surrounded by portions that make up the second end of the first expansion column.

Abstract
The present invention is directed to a medical device for expansion in a bifurcated bodily vessel. The medical device includes a first stent and at least one expansion column connected to an end of the first stent. The axes of the first stent and the expansion column(s) are generally perpendicularly oriented relative to one another, such that the expansion column(s) is/are expanded within the main branch of the bifurcated bodily vessel and the first stent is expanded within a side branch of the bifurcated bodily vessel.

- 21. A medical device, the medical device comprising a stent, wherein the stent is formed by rolling a flat pattern into a tubular shape, the flat pattern having a first end and a second end, wherein the first end is opposite the second end, the medical device having at least one petal-shaped extension extending from the first end of the flat pattern of the stent.
