Implants and methods for percutaneous perforation closure

A device for sealing an aperture in a tissue, the device comprising:

• a foot including a distal portion configured to be disposed distally beyond a distal surface of the tissue when the device is in a sealing position, and a proximal portion configured to extend proximally through the aperture and proximally beyond a proximal surface of the tissue when the device is in the sealing position;
• a thin flexible wing positionable against the distal surface of the tissue adjacent the aperture such that the flexible wing is disposed between the anterior distal portion of the foot and the distal surface of the tissue when the device is in the sealing position;
• an elongated retention member comprising a first portion and a second portion supported and housed by the proximal portion of the foot, the elongated retention member slideably moveable with respect to the proximal portion of the foot from a first position to a second position;
• and
• a guide channel extending through at least one of the foot and the thin flexible wing and configured to receive a guide wire therethrough,
• wherein, when the elongated retention member is in the first position, the guide channel is open, and
• wherein, when the elongated retention member is in the second position, the elongated retention member blocks the guide channel.
