    摘要： A microfracture instrument for applying microfracture therapy to a bone, the microfracture instrument comprising: an elongated shaft comprising a distal end and a proximal end; a needle comprising a body terminating in at least one sharp point, the needle being movably mounted to the distal end of the shaft for movement between an extended position for engaging the bone with the at least one sharp point of the needle and a retracted position for withdrawing the at least one sharp point of the needle from the bone; and a drive shaft movably mounted to the elongated shaft, the drive shaft being connected to the body of the needle so that movement of the drive shaft relative to the elongated shaft moves the needle between its extended position and its retracted position.

    摘要： A shape-changing anatomical anchor includes an activation means arranged to convert the anchor from a de-activated state to an activated state, and one or more members which extend away from the activation means and thereby change the shape of the anchor when the anchor is activated. The anchor is installed within bone and/or soft tissue when de-activated; when activated, the shape change acts to increase the force with which the anchor is retained within the tissue in which it is installed. Both piloted and non-piloted versions are described.

    摘要： A suture passer comprising: a hollow tube, the hollow tube comprising a distal end, a proximal end, a lumen extending from the distal end to the proximal end, and a window formed in the sidewall of the hollow tube, the window communicating with the lumen; and a clamping rod slidably received in the lumen of the hollow tube, the clamping rod comprising a distal end and a proximal end, the distal end being bifurcated into a first arm and a second arm, one of the first and second arms extending distally of the other of the first and second arms and including a clamping surface, and at least one of the first and second arms being outwardly biased such that when the clamping rod is moved distally so that the distal end of the at least one outwardly biased arm is adjacent to the window, the distal end of the at least one outwardly biased arm extends outwardly through the window.

    摘要： A delivery mechanism for delivering tissue holding implants through tissues to be held in approximation includes a shaft having a tip at its distal end, and which is loaded with one or more implants. A wire channel which contains a driving wire is also located within the shaft. When the mechanism is actuated, the driving wire exhibits a proportional longitudinal displacement in the wire channel, such that the wire engages an implant, conveys it along the shaft's longitudinal axis towards the tip, and forces it through the tip. The implants are oriented such that they lie along or nearly along the shaft's longitudinal axis when being conveyed along the axis. The mechanism may optionally include an opposing jaw arranged such that, when actuated, the distal end of the jaw is moved towards the tip, such that tissues placed between the jaw and tip are pinned between them.

    摘要： A medical device includes an articulating shaft with a pair of slat assemblies. By moving an articulator, the slat assemblies are configured to concurrently push while the other pulls in order to bend the articulating shaft. The articulating shaft includes a series of alternating pins and pivot members. Each pin defines an aperture that collectively forms a passageway for receiving an actuator or a tube. The pair of slat assemblies extend generally parallel to each other on opposite sides of the pins. A method for articulating a shaft of a medical device is also provided.
