Braided branching stent, method for treating a lumen therewith, and process for manufacture therefor
First Claim
1. A branching stent for deployment in a lumen, the stent comprising a body that branches into a plurality of legs, at least a first leg portion of each leg comprising a discrete plurality of continuous filaments braided together, at least a first body portion of the body comprising at least one of said continuous filaments from each discrete plurality of continuous filaments braided together, and at least one of the legs or the body comprising a second portion thereof having a non-braided, wound stent architecture comprising one or more filaments in a repeating configuration having at least one bent portion and comprising at least one of the continuous filaments from the first leg portion or first body portion.

Abstract
A bifurcated, braided stent has a body that branches into a plurality of legs and is adapted for deployment in a lumen. At least a portion of each leg of the stent comprises a discrete plurality of continuous filaments braided together, and at least a portion of the body comprises one or more of the continuous filaments from each of the legs braided together. The stent can be used for treating a diseased bifurcated lumen of a human being by deploying the stent therein. The stent can be constructed by a process comprising braiding each plurality of filaments to form the leg sections, and braiding one or more filaments from each plurality of filaments together to form the body. The process may be performed by creating the legs first and then the body, or vice versa. The stent may be constructed on a mandrel using a braiding machine.
