Abstract
A medical device for approximating and securing tissue without requiring knots includes a lock-head, a strap section, distal protuberance, and a leader section. The device also includes a transition section between the leader and the strap section and a stiffening section proximal to the protuberance. The leader section is used to draw the strap section into the body through small apertures in tissue and the transition section provides a gradual transition in stiffness and size between the leader and the strap section.
Claims21
(canceled)
A medical device configured to close a soft tissue defect, the device comprising:
- an elongate body having:
- a strap at a proximal end;
- a leader at a distal end;
- a transition section joining the strap to the leader, the transition section configured to provide a gradual transition in width between the leader and the strap,
- wherein the transition section has a length of 2 mm or more;
- and
- a lock-head disposed at the proximal end of the strap, the lock-head having an aperture for receiving the distal end of the strap, the aperture configured for permitting at least one controlled translation of the strap in a first direction through the lock-head and restricting motion in a second direction opposite the first direction, wherein the controlled translation comprises a tightening of the strap.
A medical device configured to close a soft tissue defect, the device comprising:
- an elongate body having:
- a strap at a proximal end;
- a leader at a distal end;
- a transition section joining the strap to the leader, the transition section configured to provide a gradual transition in width between the leader and the strap,
- wherein the transition section comprises a first end connecting to the leader and a second end connecting to the strap, a width of the first end being 1 mm or less, and a width of the second end being about 2.5 mm or more;
- and
- a lock-head disposed at the proximal end of the strap, the lock-head having an aperture for receiving the distal end of the strap, the aperture configured for permitting at least one controlled translation of the strap in a first direction through the lock-head and restricting motion in a second direction opposite the first direction, wherein the controlled translation comprises a tightening of the strap.
A medical device configured to close a soft tissue defect, the device comprising:
- an elongate body having:
- a strap at a proximal end;
- a leader at a distal end, wherein the leader has a lower bending stiffness than the strap;
- a transition section joining the strap to the leader, the transition section configured to provide a gradual transition in width between the leader and the strap,
- wherein the transition section comprises a first end connecting to the leader and a second end connecting to the strap, a cross-sectional area of the first end ranging between about 0.008 mm2 and about 13 mm2, and a cross-sectional area of the second end being about 3 mm2 or more, wherein the cross-sectional area of the first end is smaller than the cross-sectional area of the second end;
- and
- a lock-head disposed at the proximal end of the strap, the lock-head having an aperture for receiving the distal end of the strap, the aperture configured for permitting at least one controlled translation of the strap in a first direction through the lock-head and restricting motion in a second direction opposite the first direction, wherein the controlled translation comprises a tightening of the strap.
