Endoscopic suturing tension controlling and indication devices
First Claim
1. A suture tensioning device, comprising:
- a housing a lumen extending therethrough that defines a longitudinal axis; and
a 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; and
a 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; and
a 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.

Abstract
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.
