Left atrial appendage closure implant

A left atrial appendage closure system, comprising:

• a delivery catheter;
• a delivery shaft slidably disposed within the lumen of the delivery catheter, the delivery shaft having a distal end releasably attached to a proximal collar of a monolithic support frame, wherein the monolithic support frame is formed from a plurality of struts extending continuously between the proximal collar and a distal collar, wherein the monolithic support frame includes a longitudinal axis extending between the proximal collar and the distal collar, and wherein the plurality of struts includes a first grouping of cells adjacent to the proximal collar and defining a first row, a second grouping of cells defining a second row adjacent to the first row, a third grouping of cells defining a third row adjacent to the second row, a fourth grouping of cells defining a fourth row adjacent to the third row and a fifth grouping of cells adjacent to the distal collar and defining a fifth row adjacent to the fourth row,
• wherein the monolithic support frame extends distally and curves away from the proximal collar along a first bend, and wherein the monolithic support frame extends radially away from the first bend to a second bend, and wherein the monolithic support frame extends distally and curves radially inward along the second bend;
• wherein the monolithic support frame extends from the second bend to a third bend along a first segment, and wherein a first angle is defined between the first segment and a reference axis parallel to the central axis, and wherein the first angle is between 5 and 25 degrees;
• wherein the monolithic support frame extends from the third bend along a second segment, and wherein a second angle is defined between the first segment and the second segment, and wherein the second angle is between 20 and 65 degrees.

A method of occluding a left atrial appendage, the method including:

• positioning a left atrial appendage occlusion device adjacent a left atrial appendage, the left atrial appendage device including:
• a monolithic support frame formed from a plurality of struts extending continuously between a proximal collar and a distal collar, wherein the monolithic support frame includes a longitudinal axis extending between the proximal collar and the distal collar;
• wherein the plurality of struts includes a first grouping of cells adjacent to the proximal collar and defining a first row, a second grouping of cells defining a second row adjacent to the first row, a third grouping of cells defining a third row adjacent to the second row, a fourth grouping of cells defining a fourth row adjacent to the third row and a fifth grouping of cells adjacent to the distal collar and defining a fifth row adjacent to the fourth row;
• wherein the monolithic support frame extends distally and curves away from the proximal collar along a first bend, and wherein the monolithic support frame extends radially away from the first bend to a second bend, and wherein the monolithic support frame extends distally and curves radially inward along the second bend;
• wherein the monolithic support frame extends from the second bend to a third bend along a first segment, and wherein a first angle is defined between the first segment and a reference axis parallel to the central axis, and wherein the first angle is between 5 and 25 degrees;
• wherein the monolithic support frame extends from the third bend along a second segment, and wherein a second angle is defined between the first segment and the second segment, and wherein the second angle is between 20 and 65 degrees;
• and
• expanding the left atrial appendage occlusion device within the left atrial appendage.
