Abstract
Two spaced bodily tissues are approximated with a surgical tensioning device comprising a resilient member and a pressure locking device. The method comprises a step of routing one end of a length of suture through both spaced bodily tissues and inserting the suture end into and through the pressure locking device. The suture is then tensioned by pulling on the suture end passing through the pressure locking device. Responsive to tension changes in the suture, the pressure locking device is actuated by moving at least one surface in the pressure locking device to clamp the suture in position.
Claims17
A surgical tensioning device for holding two tissue portions in contact with one another, the device comprising:
- a resilient member extending from a first end to a second end;
- a suture attachment member disposed at the first end of the resilient member;
- and
- a pressure locking mechanism disposed at the second end of the resilient member and including opposing surfaces for engaging and clamping a length of suture to secure the suture in place without a need for knotting the suture, the pressure locking mechanism comprising:
- a hook or loop member including a channel sized to allow passage of the length of suture therethrough;
- and
- a locking member insertable:
- within the channel.
A surgical tensioning device for holding two tissue portions in contact with one another, the device comprising:
- a resilient member including a base portion, a first leg extending from a first end of the base portion, and a second leg extending from a second end of the base portion;
- a suture attachment member disposed at a first location on the first leg of the resilient member;
- and
- a pressure locking mechanism disposed at a second location on the second leg of the resilient member;
- the pressure locking mechanism comprising:
- a hook or loop member including a channel defined by a first surface;
- and
- a locking member including a second surface;
- wherein the locking member is engageable with the channel of the hook or loop member to clamp a length of suture between the first and second surfaces and to secure the suture in place without a need for knotting the suture.
A surgical tensioning device for holding two tissue portions in contact with one another, the device comprising:
- a resilient member extending from a first end to a second end;
- a suture attachment member disposed at the first end of the resilient member;
- a pressure locking mechanism disposed at the second end of the resilient member and comprising:
- a hook or loop member including a channel;
- and
- a locking member insertable within the channel;
- and
- a length of suture configured to extend from the suture attachment member and through the channel of the hook or loop member;
- the pressure locking mechanism including at least two surfaces configured to generate a locking pressure on the suture to secure the suture in place without a need for knotting the suture, the at least two surfaces including an internal surface of the hook or loop member that defines the channel and an external surface of the locking member.
