Shape memory filament for suture management

A management apparatus for disposition of a suture into a body cavity through a portion of skin overlying the body cavity, comprising:

• a delivery system defining an internal channel extending between a first end and a second end spaced apart from said first end by a channel length, said internal channel having an inner diameter;
• and
• a discrete member independent from said delivery system and configured to be presented through said internal channel from a first particular one of said ends to a second particular one of said ends, said discrete member including a single rigid shape memory alloy monofilament wound about itself and producing both a wound 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 transition from said expanded configuration to said collapsed configuration when entering into either of said ends, and further said aperture portion configured to automatically expand from said collapsed configuration to said expanded configuration when exiting from either of said ends;
• wherein said aperture portion is configured to form a predetermined perimeter having N number of hard discrete bends, wherein N is a number that is 6 or greater.

A control apparatus for disposition of a suture into a body cavity through a portion of skin overlying the body cavity, comprising:

• a percutaneous delivery system defining an internal channel extending between a first end and a second end spaced apart from said first end by a channel length, said internal channel having an inner diameter;
• a discrete member independent from said percutaneous delivery system and configured to be delivered through said internal channel from one of said ends to a different one of said ends, said discrete member including a single rigid shape memory alloy monofilament wound about itself and producing both a wound 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 transition from said expanded configuration to said collapsed configuration when entering into either of said ends, and further said aperture portion configured to automatically expand from said collapsed configuration to said expanded configuration when exiting from either of said ends;
• wherein said aperture portion is configured to form a predetermined perimeter having N number of hard discrete bends, wherein N is a number that is 6 or greater.
