Abstract
A method and apparatus for positioning a locator. The method includes inserting a tissue locator through an opening in a tissue wall, and advancing an engagement member to move a portion of the first arm from a first position to a second position that is separated from a longitudinal axis of the tissue locator by a greater distance than the first position.
Claims20
A method for closing an opening extending through a tissue wall, the method comprising:
- inserting a distal end of a tissue locator through the opening, the tissue locator comprising a shaft formed with a first arm and a second arm, each of the first arm and the second arm comprising a first end and a second end and being integrally formed with the shaft and resiliently bendable at the second end;
- advancing an elongate expander from a first position to a second position, wherein a surface of the elongate expander contacts an inner surface at each first end to pivot each first end to extend laterally away from the shaft;
- advancing a first penetrator and a second penetrator through the tissue wall, and to end faces of the first and second arms, such that the first and second penetrators respectively couple with a first end and a second end of a filament supported by the first arm and the second arm, each end face comprising an opening configured to receive a tip of one of the first penetrator and the second penetrator;
- and
- withdrawing the first and second penetrators through the tissue wall, thereby causing the first and second ends of the filament to uncouple from the first and second arms.

A method for closing an opening extending through a tissue wall, the method comprising:
- inserting a distal end of a tissue locator through the opening, the tissue locator comprising a shaft formed with a first arm, a second arm, a third arm, and a fourth arm, each arm comprising a first end and a second end, the second ends being connected to the shaft;
- advancing an elongate expander from a first position to a second position such that a surface of the expander contacts inner surfaces at the first ends of each arm to pivot the first ends of the arms to extend laterally away from the shaft;
- removably coupling a first filament between the first arm and the second arm and a second filament between the third arm and the fourth arm, wherein each filament comprises a first and second end;
- advancing a first and a second penetrator through the tissue wall to respectively couple with the first and second end of the first filament;
- advancing a third and fourth penetrator through the tissue wall to respectively couple with the first and second ends of the second filament;
- and
- withdrawing the penetrators through the tissue wall to draw the filaments across the opening,
- wherein the first filament and the second filament form part of a filament net, the filament net comprising a hub connected to the first filament and the second filament.

- and
- withdrawing the penetrators through the tissue wall to draw the filaments across the opening,
- wherein the first filament and the second filament form part of a filament net, the filament net comprising a ring with the first filament and the second filament extending through the ring.
