Medical device for modification of left atrial appendage and related systems and methods
First Claim
1. A medical device for modifying a left atrial appendage (“
- LAA”
) of a heart, comprising;
an occluder portion coupled to a hub having an axis; and
an anchor portion operably coupled to the occluder portion, the anchor portion including multiple anchor segments, at least one anchor segment including a longitudinal length, a width and a depth, the longitudinal length extending along a curved portion between a first end and a second end of the at least one anchor segment, the depth being substantially constant along the longitudinal length, the width varying along at least a portion of the longitudinal length, the first end operably coupled to the occluder portion and the second end coupled to an anchor hub, the anchor hub moveable along the axis of the hub to move the anchor portion between a retracted position and a deployed position such that a portion of the at least one anchor segment moves through the hub.

Abstract
Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a system for use in occluding an opening in the tissue of a body includes a handle, a catheter coupled with the handle and a medical device disposed within a lumen of the catheter. The medical device includes an anchor system having a plurality of anchor segments coupled with an anchor hub. The medical device further includes an occluder system having a plurality of occluder segments coupled with an occluder hub. A first actuator is configured to displace the occluder hub independent of, and relative to, the anchor hub to deploy the occluder system from a refracted state to an expanded state while the anchor system remains in a retracted state.

30. A medical device for modifying a left atrial appendage (“
- LAA”
) of a heart, the medical device comprising;a hub having an outer surface and an inner surface defining a bore and an axis therethrough; an occluder portion having multiple separate and discreet occluder frame segments, the occluder frame segments each being separately and discreetly coupled to the outer surface of the hub, each occluder frame segment having a generally planar configuration; and an anchor portion having multiple separate and discreet anchor frame segments, each of the anchor frame segments including a first end and a second end, the first ends of each of the anchor frame segments each being separately and discreetly coupled to the outer surface of the hub in an alternating arrangement with the occluder frame segments, the second ends of each of the anchor frame segments being coupled together at an anchor hub, each of the anchor frame segments having a generally planar configuration, the anchor hub moveable along the axis of the hub to move the anchor portion between a retracted position and a deployed position such that a portion of at least one of the anchor frame segments moves through the hub. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
