Braided branching stent, method for treating a lumen therewith, and process for manufacure thereof
First Claim
1. A branching stent for deployment in a lumen, the stent comprising a body that branches into a plurality of legs, wherein at least a first leg portion of each leg comprises a discrete plurality of continuous filaments braided together and at least a first body portion of the body comprises at least one of said continuous filaments from each discrete plurality of continuous filaments braided together.

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.

- 31. A method for treating a diseased branched lumen of a human being, the branched lumen comprising a main section that branches into a plurality of branches, the method comprising the step of deploying within the branched lumen a branching stent comprising a body that branches into a plurality of legs, wherein at least a first leg portion of each leg comprises a discrete plurality of continuous filaments braided together and at least a first body portion of the body comprises at least one of said continuous filaments from each discrete plurality of continuous filaments braided together, the deployment step comprising deploying the body in the main section and deploying each leg within one of the branches.

33. A process for constructing a braided, branched stent having a body and a plurality of legs, each leg comprising a discrete plurality of filaments, the process comprising the steps of:
-
a) braiding each plurality of filaments to individually form at least first leg portions of each of the legs; and
b) braiding at least one filament from each plurality of continuous filaments together to form a first body portion of the body. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)

61. A multi-section stent comprising at least one braided section, which comprises a cylindrical mesh of a first set of filaments, and at least one non-braided, wound end section, which is connected to said braided section and comprises a second set of one or more filaments in a repeating configuration having at least one bent portion, wherein at least one continuous filament is contained in both the first and second sections and forms a continuous apex in the wound end section.
