Various exemplary methods and devices are provided for tensioning sutures. The methods and devices are particularly useful in surgical suturing applications in which it is desirable to maintain tension on a suture being delivered. In various embodiments, the device is incorporated into the handle of a suture device configured to deliver a suture to a surgical site. Other embodiments comprise a device that is separate from, but may be used in connection with, a suture device configured to deliver a suture to a surgical site. A suture locking device is also provided which enables the surgeon to ascertain when a desired amount of tension has been applied to a suture prior to affixing, knotting, or tying elements thereto.
1. A suture tensioning device, comprising: a housing a lumen extending therethrough that defines a longitudinal axis; anda movable tensioning member comprising: a mounting block constrained to move axially within an axial passage in said housing along a second axis that is laterally offset from said
1. A suture tensioning device, comprising: a housing a lumen extending therethrough that defines a longitudinal axis; anda movable tensioning member comprising: a mounting block constrained to move axially within an axial passage in said housing along a second axis that is laterally offset from said longitudinal axis; anda shaft portion protruding from said mounting block configured to have a portion of a suture wound therearound such that a distal portion of the suture extends in a distal direction from the movable tensioning member to be anchored to tissue and a proximal portion of the suture protrudes from the movable tensioning member to have tension applied thereto;a spool attached to said shaft portion such that the portion of the suture may be wound therearound;a first resilient member for applying a first resistive force to said movable tensioning member in a first direction, wherein said first resilient member comprises a first coil spring; anda second resilient member applying a second resistive force to said movable tensioning member in a second direction opposite to said first direction, wherein said second resilient member comprises a second coil spring; and wherein said mounting block is centrally disposed between said first and second resilient members. 2. The suture tensioning device of claim 1 wherein said first coil spring has a first spring constant and wherein said second coil spring has a second spring constant that is substantially equal to said first spring constant. 3. The suture tensioning device of claim 1 wherein said housing comprises a portion of a handle of a suturing device configured to deliver a suture to a surgical site. 4. The suture tensioning device of claim 1 wherein said lumen is to receive a catheter of a suturing device. 5. The suture tensioning device of claim 4 further comprising: a suture locking device comprising:an indicator housing member on the catheter;a first locking element operably supported within said indicator housing member and oriented to permit said suture to extend therethrough;a second locking element supported relative to said first locking element and configured to retainingly engage said first locking element upon application of a firing motion to said first locking element to thereby cause a portion of the suture extending through said first locking element to be locked between said first and second locking elements; andan indicator member supported within said indicator housing and configured to only be viewable through an external wall thereof when an excessive amount of tension has been applied to the suture prior to applying the firing motion to said first locking member. 6. The suture tensioning device of claim 5 further comprising at least one indicator window in said external wall of said indicator housing such that when an excessive amount of tension has been applied to the suture prior to the application of said firing motion, said indicator member is viewable through said at least one indicator window. 7. The suture tensioning device of claim 5, further comprising: a handle; anda drive cable operably coupled to said handle and said first locking element for applying said firing motion thereto. 8. The suture tensioning device of claim 7 wherein said drive cable is coupled to said indicator member and wherein said indicator member operably interfaces with said first locking element. 9. The suture tensioning device of claim 7 wherein said drive cable extends through the catheter extending between said handle and said housing member and wherein said suture tensioning device further comprises a second indicator member interfacing with said drive cable and configured to only be viewable through said catheter adjacent said handle when an excessive amount of tension has been applied to the suture prior to applying the firing motion to said first locking member. 10. The suture tensioning device of claim 6 wherein said indicator member has a color that is readily viewable through said at least one indicator window. 11. A suture application and management kit, comprising: a suturing device configured to deliver a suture to a surgical site; anda suture tensioning device of claim 1. 12. The suture application and management kit of claim 11 wherein the suturing device includes at least one end effector configured to apply at least one fastener to tissue, the suture being coupled to the at least one fastener. 13. The suture application and management kit of claim 11 wherein the suture tensioning device is coupled to the suturing device configured to deliver a suture to a surgical site. 14. A method for processing an instrument for surgery, the method comprising: obtaining the suture tensioning device of claim 1; sterilizing the suture tensioning device; andstoring the suture tensioning device in a sterile container.
