Medical device for modification of left atrial appendage and related systems and methods

Abstract

The invention is themed by a medical device for modification of a left atrial appendage and related systems and methods. 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 medical device includes an occluder portion and an anchor portion. The occluder portion includes a hub that defines an axis, theoccluder portion extending between a proximal end coupled to the hub and a distal end defining an occluder eyelet adjacent thereto. The anchor portion extends between a first end and a second end, thefirst end coupled to an anchor hub and the second end defining an anchor eyelet adjacent thereto and hingeably coupled to the occluder eyelet. With this arrangement, the anchor hub is moveable alongthe axis to move the anchor portion between a retracted position and a deployed position upon the occluder portion being in an expanded position.

Problems solved by technology

[0007] However, due to the wide variation in LAA orifice size and volume, existing implantable devices are often not configured to accommodate such variations, making these devices unsuitable for most LAA anatomies

Additionally, such implantable devices are substantially limited by the orientation through which such implantable devices can be successfully deployed
