    摘要: A handle assembly for a drive tool includes a plunger actuator configured to move a plunger of the drive tool between a retracted position and an extended position, an outer tube actuator configured to move an outer tube of the drive tool between a retracted position and an extended position, and a coupler configured to move the outer tube from its extended position to its retracted position in response to movement of the plunger from its extended position to its retracted position. The drive tool delivers a suture securing device to a surgical site. When the plunger actuator moves the plunger to its extended position, a second member of the device is secured to a first member of the device. When the plunger actuator moves the plunger to a second, further extended position, the plunger deploys the secured first and second members from the drive tool.

    摘要: A method according to one embodiment may provide access to an articular surface of a bone. The method includes forming a passage through at least a portion of the bone. The passage provides an opening in the articular surface. The method further includes inserting a tether through the passage. The tether inserted through the passage can be coupled to at least one device from an insertion site remote from the articular surface. The tether can be withdrawn through the passage to convey the device to a location proximate the articular surface.
