Body part repositioning apparatus and method

A completely atraumatic method for repositioning a left atrial appendage (LAA) of a heart, comprising:

• transseptally and transvasculary introducing a guide instrument within a human body;
• wherein said guide instrument comprising a suction channel passing through a lumen of said guide instrument terminating with a concave holder, said suction channel and said concave holder are enclosed within said lumen of said guide instrument during said introducing;
• distally positioning said guide instrument in a left atrium (LA) distal to an ostium of said LAA;
• extending said suction channel and radially expanding said concave holder from said lumen of said guiding instrument into said LAA;
• holding a portion of the LAA by said concave holder by applying suction through said suction channel without imparting damage to the LAA, until said portion of the LAA is held and drawn into a lumen of said concave holder;
• fully inverting said held LAA portion into said LA while said held LAA portion is outside said lumen of said guide instrument;
• extending forward and expanding a fastener from said lumen of said guide instrument, wherein said fastener is shaped and sized to be enclosed within said lumen of said guide instrument during said introducing;
• and
• fastening said fully inverted LAA portion by said fastener;
• wherein all of said steps being performed without imparting damage to the LAA,
• and
• wherein said fastening comprising actuating said fastener from within said lumen of said guide instrument in such a way to be wrapped around said fully inverted LAA portion to permanently prevent return thereof to its normal position and to close said LAA.
