  • Patent number: 6348061
    Abstract: A selectively coupleable and remotely actuateable surgical attachment for use with an electromechanical driver device for use in expanding occluded vessels and lumens. The attachment includes an axial rod which is coupleable to the electromechanical driver device, and which is selectively rotateable in accordance with the action of the electromechanical driver device. The rod is also threaded in opposing orientations at either end thereof. A pair of nuts are mounted to the rod, and specifically on the opposing threads. The rod and nuts are disposed within an axial track which permits the rod to turn, but constrains the rotational motion of the nuts, thereby permitting the nuts to move axially along the threadings of the rod when the rod turns. Attached to the nuts are a series of jointed spokes which are coupled to a flexible tubular shroud which surrounds the entire assembly.

  • Patent number: 6315184
    Abstract: A stapling device for use as an attachment to an electromechanical device driver comprises an upper jaw and a lower jaw, the upper jaw having staple guides corresponding to one or more staples in a removable staple tray disposed within a lower jaw, whereby a wedge having a threaded bore travels upon a matching threaded shaft in a channel disposed in the lower jaw behind the staple tray, such that rotation of the threaded shaft causes movement of the wedge through the channel while a sloped surface of the wedge contacts the staples to push the staples against the staples guides, closing the staples.

  • Patent number: 6264087
    Abstract: A cutting and stapling device for use as an attachment to an electromechanical device driver comprises an upper jaw and a lower jaw which separate and close against one another in a continuously parallel alignment. The upper jaw includes a series of staple guides corresponding to one or more staples in a removable staple tray disposed within a lower jaw, whereby a blade and wedge having a threaded bore travel upon a matching threaded shaft in a channel disposed in the lower jaw below the staple tray, such that rotation of the threaded shaft causes movement of the wedge through the channel while a sloped surface of the wedge contacts the staples to push the staples against the staples guides, closing the staples.
