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.
Claims20
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 when the device is in a relaxed configuration;
- and
- only one flange attached to the body proximate the second end of the body, the only one flange comprising a flange width transverse to the longitudinal axis and a concave surface facing the first end of the body when the device is in the relaxed configuration,
- wherein, when the device is in the relaxed configuration, the body width of the body proximate the only one flange is greater than half of the flange width.
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;
- and
- only one flange attached to the body proximate the second end of the body, the only one flange having an outermost flange peripheral edge, wherein the flange peripheral edge is at a longitudinal position intermediate the first and second ends of the body.
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;
- and
- only one flange attached to the body proximate the second end of the body, the only one flange having an outermost flange peripheral edge, wherein the flange peripheral edge comprises an annular portion oriented perpendicular to the longitudinal axis.
