First Claim
Patent Images
1. A medical stent device, comprising:
- a biocompatible shape memory material formed as a continuous unitary wire structure including a first plurality of arches defining a first plane, a second plurality of arches defining a second plane spaced apart from the first plane, and a third plurality of arches connecting the first and second plurality of arches;
wherein the third plurality of arches is generally transverse relative to the first and second plurality of arches, and apical portions of the third plurality of arches define a generally cylindrical opening around which the first, second, and third pluralities of arches are generally centered.

Abstract
A stent made of single nitinol wire or other biocompatible material having shape memory properties may be configured to define a flower-like configuration generally providing a proximal plane and a distal plane, each generally centered around a generally cylindrical passage and configured for maintaining patency of an anastomosis or other opening. The wire or other biocompatible material may include a shroud or other covering and may also include one or more loops configured to allow relatively secure engagement of sutures. Methods of deployment are also provided.

16. A medical stent device, comprising:
-
a biocompatible shape memory material formed as a continuous unitary wire structure including a plurality of alternating first arches and second arches, and having a first, non-deployed configuration and a second, deployed configuration; wherein, the first, non-deployed configuration includes the first plurality of arches having their apices all drawn in proximity to each other, thereby forming a generally columnar first low profile and the second plurality of arches having their apices all drawn in proximity to each other, thereby forming a generally columnar second low profile; wherein, the second, deployed configuration includes the first plurality of arches having their apices spread apart each other, the first arches'"'"' apices thereby forming a generally columnar first expanded profile having an outside diameter greater than the first low profile, and the second plurality of arches having their apices spread apart each other, the second arches'"'"' apices thereby forming a generally columnar second expanded profile having an outside diameter greater than the second low profile; wherein, in the second deployed configuration, the first plurality of arches defines a first plane, the second plurality of arches defines a second plane that is spaced apart from the first plane; and wherein apices of a third plurality of arches connect the first and second plurality of arches, the apical portions of the third plurality of arches define a generally cylindrical opening around which the first, second, and third pluralities of arches are generally centered, and the apical portions of the third plurality of arches are generally transverse relative to the first and second plurality of arches in the second, deployed configuration. - View Dependent Claims (17, 18, 19, 20)
