  • Patent number: 10555731
    Abstract: A surgical suturing device having an axis extending between a proximal end and a distal end is operable to move a suture through body tissue. An actuating rod extends between the handle assembly and the shaft. A needle assembly at the distal end of the actuating rod is movable with the actuating rod between an extended state and a retracted state. Bifurcated portions of the needle assembly define a suture slot, the bifurcated portions have a proximate relationship when the needle assembly is in the retracted state and having a separated relationship when the needle assembly is in the extended state. The needle assembly is biased to the retracted state and the bifurcated portions are biased to the separated relationship. A handle assembly is configured to releasably receive the needle assembly and is operable to move the needle assembly between a free suture state and a captured suture state.

  • Patent number: 7686807
    Abstract: A tool for inserting a bone fixation device is provided. The tool generally includes an elongate outer body and an elongate inner body, each having a proximal end, a distal end, and a longitudinal axis. The tool typically includes a pin-receiving portion at the distal end of the outer body for receiving a proximal pin of a bone fixation device. The tool may further include first and second levers pivotally mounted to the inner member at respective pivot axes, and each of the levers having a gripping portion. The levers preferably include finger engagement portions, wire-gripping portions, and are preferably configured to be axially movable relative to the outer body. The levers are generally configured such that a proximal force on the finger engagement portions relative to the outer body will cause the pin engagement portions to close and to move proximally such that a guidewire of a bone fixation device placed between the wire-gripping portions may be gripped and pulled proximally.

  • Patent number: 7553275
    Abstract: 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.
