An improved method and apparatus is provided to secure a suture relative to body tissue. When a predetermined minimum force is being transmitted between a suture retainer and the body tissue, the suture is gripped with the suture retainer by plastically deforming material of the suture retainer. One or more bends may be formed in suture by the suture retainer to increase the holding action between the suture retainer and the suture. The bends in the suture may be formed by wrapping the suture around a portion of the suture retainer. During movement of the suture retainer toward the body tissue, the bends may be moved along the suture. One or more bends may be formed in the suture by bending a tubular member through which the suture extends. The tubular member may be maintained in a bent condition by a C-shaped holder member. Alternatively, the tubular member may be maintained in a bent condition by members which are latched together.
A method of securing a suture relative to body tissue, said method comprises the steps of providing a retainer including first and second members, resiliently deflecting the first member from a first condition to a second condition, moving the first member into alignment with at least a portion of the second member while maintaining the first member in the first condition, thereafter, releasing the first member with a portion of the suture disposed between the first and second members, and gripping the portion of the suture with the first and second members by resiliently pressing the first member against the second member under the influence of resilience of material forming the first member.
A method of securing a suture relative to body tissue, comprising the steps of:
A method of securing a suture, said method comprising the steps of providing a retainer including first and second members, wrapping a portion of a suture around the first member forming a plurality of turns of the suture around the first member, moving the first member and the plurality turns to position the first member relative to body tissue, and clamping the suture between the first member and the second member while the suture is wrapped around the first member.
A method of securing a suture, comprising the steps of resiliently deflecting a first member from a first condition to a second condition, positioning the first and second members relative to each other with a portion of a suture disposed between the first and second members, and clamping the suture between the first and second members, said step of clamping the suture between the first and second members includes changing the condition of the first member from the second condition toward the first condition by reducing resilient deflection of the first member.
A method of securing a suture comprising the steps of providing a retainer including first and second members, contracting the first member, positioning the first member in an opening in the second member with a suture extending through the opening in the second member, and expanding the first member while the first member is in the opening in the second member to clamp the suture between the first and second members.
