Medical device and system with enhanced echogenicity and method thereof

A medical device configured to be percutaneously delivered to a heart with a catheter of a medical device delivery system, the medical device comprising:

• a framework including a hub with frame segments extending radially from the hub;
• and
• a tissue growth member attached to the framework, the tissue growth member extending radially along the framework such that the tissue growth member extends to define an outer surface and an inner surface, the framework coupled to the inner surface of the tissue growth member, the tissue growth member extending with multiple voids defined therein, the tissue growth member including a filler material configured to temporarily fill the multiple voids of the tissue growth member.

A method for occluding an opening in a heart, the method comprising:

• providing a medical device system extending to define a delivery system and an implant, the delivery system including a handle and a catheter, the catheter being removably coupled to the implant, the implant extending to define a framework, the framework including a hub with frame segments extending radially from the hub, the framework being attached to a tissue growth member, the tissue growth member extending radially along the framework to define an outer layer portion and an inner layer portion, the framework coupled to the inner layer portion, the tissue growth member extending to define multiple voids therein, the tissue growth member including a filler material configured to temporarily fill the multiple voids of the tissue growth member;
• and
• positioning the implant within a left atrial appendage of the heart.
