Suture pulley for use with graft tensioning device
First Claim
1. In a graft tensioning device for use in joint repair surgery, a suture pulley assembly comprising:
- a pulley wheel comprising first and second pulley plates sized and positioned so as to define a pulley space therebetween;
attaching means for rotatably attaching said pulley wheel to an adjustable tension applicator of the graft tensioning device; and
biasing means for biasing at least one of said pulley plates toward the other of said pulley plates.

Abstract
A suture pulley assembly includes a pulley wheel that is rotatably attached to an adjustable tension applicator used in joint repair surgery (e.g., to repair an ACL) so as to equalize the tensile load that is applied to each side of a looped suture by the adjustable tension applicator. The pulley wheel includes a pair of pulley plates that define a pulley space therebetween into which a looped suture is placed and that are oppositely-biased in order to spread apart and contract in response to differences in size of the looped suture as a result of, e.g., the existence of a knot or half knot. The pulley wheel is rotatably attached to the tension applicator by a post. A spring biases one of the suture pulley plates toward the other in a manner that allows for the aforementioned expansion of the pulley space.

11. In a graft tensioning device for use in joint repair surgery, a suture pulley assembly comprising:
-
a pulley wheel comprising first and second pulley plates sized and positioned so as to define a pulley space therebetween;
a post attached at a first end to an adjustable tension applicator of the graft tensioning device, said post passing through a central recess of each of said first and second pulley plates so as to rotatably attach said pulley wheel to the adjustable tension applicator; and
a spring positioned relative to at least one of said first and second pulley plates so as to bias at least one of said pulley plates toward the other of said pulley plates. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A graft tensioning device for use in joint repair surgery, comprising:
-
at least one adjustable tension applicator configured to apply a desired tensile load to a looped suture attached to free ends of a looped tissue graft; and
a suture pulley assembly rotatably attached to said adjustable tension applicator so as to equalize a tensile load applied by said adjustable tension applicator to each side of the looped suture, said suture pulley assembly comprising;
a pulley wheel comprising first and second pulley plates sized and positioned so as to define a pulley space therebetween;
a post attached at a first end to an adjustable tension applicator of the graft tensioning device, said post passing through a central recess of each of said first and second pulley plates so as to rotatably attach said pulley wheel to the adjustable tension applicator; and
a spring positioned relative to at least one of said first and second pulley plates so as to bias at least one of said pulley plates toward the other of said pulley plates.
