A percutaneous suture management system for a suture disposed inside a body cavity having a portion of skin overlying the body cavity, comprising: an elongate tissue-penetrating member including a proximal end and a distal end opposing said proximal end, said distal end having a skin-piercing element configured to pierce the portion of skin with said elongate tissue-penetrating member having an internal channel extending between a proximal opening at said proximal end and a distal opening at said distal end, said distal opening proximate said skin-piercing element and said internal channel having an inner diameter and a channel length; and a discrete member disconnected from said elongate tissue-penetrating member and configured to be delivered through said internal channel from one of said ends to the other of said ends, said discrete member consisting essentially of a single rigid shape memory monofilament wound about itself and producing both a body portion and an aperture portion, said body portion having a body portion width less than said inner diameter and a body portion length greater than said channel length, said aperture portion including an expanded configuration having an expanded width greater than said inner diameter and a collapsed configuration having a collapsed width less than said inner diameter, said aperture portion configured to automatically transition from said expanded configuration to said collapsed configuration when entering into said proximal opening and when entering into said distal opening, and further said aperture portion configured to automatically transition from said collapsed configuration to said expanded configuration when exiting from said proximal opening and when exiting from said distal opening. an elongate tissue-penetrating member including a proximal end and a distal end opposing said proximal end, said distal end having a skin-piercing element configured to pierce the portion of skin with said elongate tissue-penetrating member having an internal channel extending between a proximal opening at said proximal end and a distal opening at said distal end, said distal opening proximate said skin-piercing element and said internal channel having an inner diameter and a channel length; and a discrete member disconnected from said elongate tissue-penetrating member and configured to be delivered through said internal channel from one of said ends to the other of said ends, said discrete member consisting essentially of a single rigid shape memory monofilament wound about itself and producing both a body portion and an aperture portion, said body portion having a body portion width less than said inner diameter and a body portion length greater than said channel length, said aperture portion including an expanded configuration having an expanded width greater than said inner diameter and a collapsed configuration having a collapsed width less than said inner diameter, said aperture portion configured to automatically transition from said expanded configuration to said collapsed configuration when entering into said proximal opening and when entering into said distal opening, and further said aperture portion configured to automatically transition from said collapsed configuration to said expanded configuration when exiting from said proximal opening and when exiting from said distal opening.
