1. A medical device for deployment in a body, wherein the device comprises:
- a tubular body comprising a first end and a second end, the body defining a longitudinal axis extending between the first end and the second end, the body comprising a body width measured transverse to the longitudinal axis; and
a flange attached to the body proximate the second end of the body and extending outwardly from the body and around an entire periphery of the body, the flange comprising a flange width transverse to the longitudinal axis, a concave outer surface facing the first end of the body and a convex outer surface facing the second end of the body, the concave and convex surfaces respectively joining together at a flange lip located between the first and the second ends of the body, spaced inward from the second end along the longitudinal axis, and proximate an outermost dimension of the flange width;
wherein, when the device is in a relaxed configuration, the body width proximate the flange is half or more of the flange width.

Abstract
Implantable occlusion devices that include one or more flanges extending from a tubular body are disclosed. The flange or flanges may assist in retention of the device within a vessel, cavity, appendage, etc. At least one flange on the occlusion device may include a concave surface proximate one end of a body. Because of the shape of the flange, e.g., its concavity, the occlusion device may resist dislocation due to e.g., the forces generated within the left atrial appendage during atrial fibrillation.

10. A medical device for deployment in a body, wherein the device comprises:
-
a tubular body comprising a first end and a second end, the body defining a longitudinal axis extending between the first end and the second end, the body comprising a body width measured transverse to the longitudinal axis; and only one flange attached to the body proximate the second end of the body and extending outwardly from the body and around an entire periphery of the body, the only one flange comprising a flange width transverse to the longitudinal axis, a concave outer surface facing the first end of the body and a convex outer surface facing the second end of the body, the concave and convex surfaces respectively joining together at a flange lip located between the first and the second ends of the body, spaced inward from the second end along the longitudinal axis, and proximate an outermost dimension of the flange width, wherein the width of the body proximate the only one flange is half or more of the width of the flange when the device is in the relaxed configuration. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
