摘要： A medical device configured to form one or more holes within a bone of a patient may include a handle assembly including a housing, a lever rotatably coupled to the housing, and a sheath extending distally from the housing, the handle assembly including a spring biasing the lever toward an initial or intermediate position; and a bone punch including an elongate shaft, a head at a proximal end of the elongate shaft, and a piercing tip at a distal end of the elongate shaft configured to be driven into the bone. The elongate shaft may be slidably disposed within the sheath in a first position when the lever is in the initial or intermediate position. Translation of the bone punch distally within the sheath from the first position to a second position may cause a distal end of the lever to rotate away from the housing to an extended position.

摘要： An implant delivery system including a fixation member delivery system including an elongate shaft, first and second rails, a plurality of fixation members with each fixation member slidably disposed on the first and second rails and an actuation assembly. The actuation assembly includes a first elongate member including a first plurality of engagement members disposed along the first elongate member with a distal end region of each engagement member in engagement with one of the fixation members, a second elongate member including a second plurality of engagement members disposed along the second elongate member with a distal end region of each engagement member in engagement with one of the fixation members. Additionally, cyclical actuation of the actuation assembly is configured to incrementally move the fixation members distally along the first and second rails to deploy each of the plurality of fixation members in sequence.
