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.

1. A surgical tensioning device for dynamically 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, the resilient member being normally biased such that the first and second legs converge distally towards each other in a first configuration;a suture attachment member disposed on the first leg; anda pressure locking mechanism disposed on the second leg, said pressure locking mechanism having a surface for engaging and clamping a length of suture passing therethrough to secure the suture in place without a need for knotting the suture, said pressure locking mechanism including a tube having an internal tubular wall which comprises said surface, said suture being sized to pass through a lumen in said tube defined by said internal tubular wall and tensioned by pulling on an end of the suture, thereby causing the first and second legs to move from the first configuration to a second configuration in which the first and second legs are flexed apart to store energy in the base portion sufficient to supply continuing tension to the suture, and said internal tubular wall being collapsible about the suture when pressure is applied to the tube by an external device to lock the suture in a tensioned state. 2. The surgical tensioning device as recited in claim 1, wherein the base portion and the first and second legs of the resilient member form a spring element. 3. The surgical tensioning device as recited in claim 1, wherein the suture attachment member is disposed at a distal end of the first leg and the pressure locking mechanism is disposed at a distal end of the second leg. 4. The surgical tensioning device as recited in claim 1, wherein the suture attachment member comprises a hook or a loop. 5. The surgical tensioning device as recited in claim 1, wherein the suture attachment member comprises a second pressure locking mechanism. 6. The surgical tensioning device as recited in claim 1, wherein said internal tubular wall is an internal cylindrical wall. 7. The surgical tensioning device as recited in claim 1, wherein the suture comprises flat suture. 8. A surgical tensioning device for dynamically 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, the resilient member being normally biased such that the first and second legs converge distally towards each other in a first configuration;a suture attachment member disposed on the first leg; anda pressure locking mechanism for securing suture in place at a procedural site, said pressure locking mechanism coupled to the second leg and including a tube having an internal tubular wall defining a lumen for receiving and clamping a length of suture passing therethrough without a need for knotting the suture, the suture configured to be tensioned by pulling on an end of the suture, thereby causing the first and second legs to move from the first configuration to a second configuration in which the first and second legs are flexed apart to store energy in the base portion sufficient to supply continuing tension to the suture, said internal tubular wall being collapsible about the suture when pressure is applied to the tube by an external device, thereby permanently distorting the tube and securing the suture in place in a tensioned state. 9. The surgical tensioning device as recited in claim 8, wherein said internal tubular wall is an internal cylindrical wall. 10. A surgical tensioning device for dynamically 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, the resilient member being normally biased such that the first and second legs converge distally towards each other in a first configuration;an attachment member provided on the first leg for securing an end portion of a suture; anda pressure locking mechanism provided on the second leg, the pressure locking mechanism including a tube having an internal cylindrical wall for engaging and clamping a length of the suture passing through a lumen defined by the internal cylindrical wall, the suture configured to be tensioned by pulling on an end of the suture, thereby causing the first and second legs to move from the first configuration to a second configuration in which the first and second legs are flexed apart to store energy in the base portion sufficient to supply continuing tension to the suture;wherein when pressure is applied to the tube by an external device, the internal cylindrical wall collapses about the suture to secure the suture in place, in a tensioned state, without a need for knotting the suture.
