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

A medical device system comprising:

• a medical device comprising:
• a plurality of frame segments coupled with at least one ring member, the at least one ring member having an inner surface defining notches radially spaced therein, each of the plurality of frame segments configured to be positioned within one of the notches of the at least one ring member to form a frame structure, each frame segment including:
• a hub portion having an upper surface configured to be captured in one of the notches defined in the at least one ring member;
• and
• at least one leg portion extending from the hub portion;
• a tissue growth member coupled with the plurality of frame segments to define a substantially convex surface and a substantially concave surface;
• a catheter;
• and
• a pusher member configured to displace the medical device relative to the catheter.

A method of forming a medical device, the method comprising:

• forming a plurality of frame segments, each frame segment including a hub portion and at least one leg portion;
• coupling the hub portion of each of the plurality of frame segments with at least one ring member such that the at least one ring member includes an inner surface defining notches radially spaced therein so that an upper surface of the hub portion of each of the plurality of frame segments is captured in one of the notches of the at least one ring member;
• and
• coupling a tissue growth member with the plurality of frame segments.
