<p>The present invention is directed to novel surgical systems that include a combination of an improved bone fastener, suture grasping device and/or suture throw rundown instrument. The systems can be used, e.g., for endoscopic procedures to repair and reattach soft tissues. The systems include a bone fastener comprising an expandable member having an axial channel and an elongated element inserted into the axial channel. The expandable member is configured to be insertible into a bore drilled in bone. The member is expanded using a continuous, compressive force (i.e., pressure without impulse or impact). The expandable member is grasped at its distal end throughout the emplacement procedure and is axially released from an emplacement tool. The systems can further include a suture grasping device comprising a rigid, hollow shaft, a rod, a first elongate wire-like element, a second elongated wire-like element, and an actuation device. The systems further include a suture throw rundown element comprising a handle assembly having first and second handle members movably connected for movement relative to one another, an elongate rod releasably secured to the first handle member.</p> |
