Abstract
An anchor includes an anchor body configured to be retained within base tissue. The anchor body includes a unidirectional mechanism to selectively restrict passage of a flexible member through the anchor. The flexible member includes a loop to enable attachment of candidate tissue to base tissue without the use of knots.
Claims44
A flexible member anchor comprising:
- a flexible member including a loop;
- and
- a body having:
- a channel through which the flexible member is disposed, the channel including a unidirectional mechanism configured to allow movement of the flexible member through the channel in a first direction and to restrict movement of the flexible member through the channel in a second direction;
- and
- an anchoring mechanism configured to anchor the body in base tissue.
3 more elements
A flexible member anchor comprising:
- a body including an axial member having a distal end and a proximal end, the axial member comprising a channel through which flexible member passes, the channel comprising:
- a linear channel portion including a tapered transverse cross section having a wide portion and a narrow portion, and
- a first plurality of ridges forming a portion of the linear channel portion, the first plurality of ridges oriented from the wide portion to the narrow portion and not parallel to the tapered transverse cross section;
- and
- a second plurality of ridges disposed peripherally on the axial member.
2 more elements
A surgical method comprising:
- attaching a flexible member to candidate tissue using a loop;
- inserting the flexible member into a flexible member anchor,
- attaching the flexible member anchor to base tissue;
- pulling the flexible member through the flexible member anchor to adjust spacing between the base tissue and the candidate tissue;
- and
- maintaining the spacing using a unidirectional mechanism of the flexible member anchor.
