Assembly and method for left atrial appendage occlusion

An assembly structured to perform an occlusion of the left atrial appendage, said assembly comprising:

• a delivery instrument structured for operative disposition in communicating relation with an interior of the left atrial appendage, said delivery instrument including a cover structure removably connected thereto,
• occlusion material comprising at least one elongated strand of flexible material mounted on said delivery instrument,
• said delivery instrument operative for progressive axial dispensing of the length of said at least one strand therefrom into the interior of the left atrial appendage, when said delivery instrument is in said operative disposition,
• a dispensed portion of said at least one strand being of sufficient length and flexibility to define a progressively formed arbitrarily intermingled array of said occlusion material within the interior of the left atrial appendage,
• said cover structure structurally adapted to be disposed in a covering orientation, wherein said covering orientation comprises said cover structure disconnected from said delivery instrument and disposed in covering relation to an entrance to the left atrial appendage, said covering orientation comprising at least a portion of said cover structure disposed exteriorly of the entrance of the left atrial appendage,
• said at least one strand including a proximal end and a distal end each remaining connected to said cover structure concurrent to said cover structure being in said covering orientation,
• said cover structure comprising a plurality of ribs movable between a collapsed orientation and an expanded orientation, at least a majority of said plurality of ribs including a gripping member movably connected to a free distal end thereof,
• said collapsed orientation comprising said gripping members disposed in substantially coplanar relation with a remainder of corresponding ones of said distal ends on an interior of said delivery instrument,
• said expanded orientation further comprising each of said gripping members biased transversely outward from corresponding ones of said distal ends, when said cover structure is in said expanded orientation, and
• wherein said at least one strand forming the arbitrarily intermingled array is not attached to itself along its length and is not attached to tissue portions of the heart corresponding to the left atrial appendage when the cover structure is in said covering orientation, and
• wherein when in the covering orientation, each of said plurality of ribs extend radially outwardly and do not project distally of a distal end of a distal end portion.
