Arthroscopic suture passing devices and methods
First Claim
1. A system for transdermal repair of soft tissue, said system including an instrument comprising:
- a proximal actuator portion;
a fixed needle having a lumen and extending distally from said proximal actuator portion;
a movable needle having a lumen and extending distally from said proximal actuator portion, the movable needle being movable axially between an advanced position and a retracted position relative to said proximal actuator portion;
a suture needle disposed within the lumen of one of said fixed and movable needles, the suture needle having a length of Suture connected thereto;
a first needle grasper disposed in the lumen of said one of said fixed and movable needles, proximally of the suture needle, and having first grasper jaws disposed on a distal end thereof which are movable between a closed orientation and an open orientation, said first grasper jaws being adapted for securing a first end of said suture needle;
and further comprising a second needle grasper disposed in the lumen of the other of said fixed and movable needles, and having second grasper jaws disposed on a distal end thereof which are movable between a closed orientation and an open orientation, said second grasper jaws being adapted for securing a second end of said suture needle.

Abstract
A system for transdermal repair of soft tissue includes an instrument comprising a proximal actuator portion, a fixed needle having a lumen and extending distally from the proximal actuator portion, and a movable needle having a lumen and extending distally from the proximal actuator portion. The movable needle is movable axially between an advanced position and a retracted position relative to the proximal actuator portion. A suture needle is disposed within the lumen of one of the fixed and movable needles, and has a length of suture connected thereto. Needle graspers are disposed in the lumen of each needle, for securing the suture needle and assisting in the transfer of the suture needle from one needle to the other to complete a suture passing step.

11. A system for transdermal repair of soft tissue, said system including an instrument comprising:
-
a proximal actuator portion; a curved needle having a lumen and extending distally from said proximal actuator portion; a movable straight needle having a lumen and extending distally from said proximal actuator portion, the movable needle being movable axially between an advanced position and a retracted position relative to said proximal actuator portion; a suture needle disposed within the lumen of one of the straight and curved needles, the suture needle having a length of suture connected thereto; a first needle grasper disposed in the lumen of said one of the straight and curved needles, proximally of the suture needle, and having first grasper jaws disposed on a distal end thereof which are movable between a closed orientation and an open orientation, said first grasper jaws being adapted for securing a first end of said suture needle, said needle grasper being axially movable within the lumen of said one of the straight and curved needles, relative to that needle; and a second needle grasper disposed in the lumen of the other of the straight and curved needles and having second grasper jaws disposed on a distal end thereof which are movable between a closed orientation and an open orientation, said second grasper jaws being adapted for securing a second end of said suture needle, said second needle grasper being axially movable within the lumen of the other of the straight and curved needles, relative to that needle. - View Dependent Claims (12, 13, 14, 15, 16)
