DEVICES FOR ADJUSTABLY TENSIONING SUTURES, AND ASSOCIATED SYSTEMS AND METHODS

Disclosed herein are devices, systems, and methods for adjustably tensioning sutures, such as sutures used to close a catheter access site of a human patient. In some embodiments, a suture tensioning device includes a housing and an actuation member slidably coupled to the housing. The housing can include a first through-hole and a second through-hole at least partially aligned along an axis. The actuation member can include a third-through-hole. The suture tensioning device can further include a biasing member operably coupled between the actuation member and the housing. The biasing member can bias the actuation member to a first position in which the third through-hole is offset from the axis. The actuation member is movable to a second position in which the third through-hole is at least partially aligned with the first and second through-holes along the axis.
