Left atrial appendage implant with distal engagement element

A medical device for a left atrial appendage closure, comprising:

• only one proximal collar and only one distal collar;
• a support frame including a plurality of struts, the support frame having a proximal end region with the proximal collar, a medial region, and a distal end region with the distal collar, wherein distal ends of all of the plurality of struts are coupled directly to the distal collar, wherein the support frame is actuatable from a first constrained delivery configuration to a second deployed configuration in which at least the medial region is radially expanded to engage an inner wall of the left atrial appendage, wherein the support frame in the second deployed configuration defines a flattened ball shape with a circumferential side wall and proximal and distal faces extending transverse to a longitudinal axis extending through the proximal and distal collars;
• a membrane disposed on at least the proximal end region of the support frame;
• and
• an engagement element including a plurality of atraumatic members extending distally beyond a distal endpoint of the support frame, the plurality of atraumatic members configured to engage the inner wall of the left atrial appendage and prevent the support frame from sliding along the inner wall during implantation, wherein at least some of the plurality of atraumatic members are first wires fixed directly to the plurality of struts on the distal face of the support frame, spaced radially inward from the circumferential side wall.
