A medical device for left atrial appendage closure, comprising: a delivery catheter having a lumen extending therethrough; a left atrial appendage closure implant comprising a proximal collar, a distal collar, and a monolithic support frame extending therebetween; and a delivery shaft slidably disposed within the lumen of the delivery catheter, the delivery shaft having a distal end removably connected to the left atrial appendage closure implant at the proximal collar; wherein the support frame includes: a first bend extending from the proximal collar to a second bend; a first segment extending from the second bend to a third bend; a second segment extending from the third bend to a fourth bend; and a third segment extending from the fourth bend to the distal collar, the third segment extending proximally and radially inward, wherein the distal collar is disposed proximal of the fourth bend; wherein the support frame is actuatable from a first constrained position to a second flowering position to a third mid-deployment position to a fourth unconstrained position; wherein in the first constrained position, the left atrial appendage closure implant is disposed within the lumen of the delivery catheter with the first bend, the second bend, and the third bend substantially straightened into an elongated shape, and the fourth bend bent such that the second segment and the third segment are generally parallel to each other; wherein in the second flowering position, the left atrial appendage closure implant is partially disposed within the lumen of the delivery catheter such that the fourth bend is opened compared to the first constrained position, and the second segment is translated radially outward compared to the first constrained position; wherein, in the fourth unconstrained position, the left atrial appendage closure implant is disposed outside of the delivery catheter, wherein the support frame at the second bend extends radially outward farther than at the third bend to define a widest lateral extent of the left atrial appendage closure implant. a delivery catheter having a lumen extending therethrough;
