Abstract: A stent-graft delivery system includes an elongate shaft, a tip capture spindle disposed over the shaft, and a distal tip assembly coupled to the distal end of the shaft. At least one component of the delivery system constrains a stent of the stent-graft engaged with the tip capture spindle during delivery and partial-deployment of the stent-graft, and the at least one component is in a threaded relationship with the distal tip assembly. To fully deploy the stent-graft, the elongate shaft, having the distal tip assembly coupled thereto, is rotated to result in longitudinal movement of the at least one component and thereby release the stent from the tip capture spindle. The at least one component that longitudinally moves to fully deploy the stent-graft may be the tip capture spindle and/or a relatively short sleeve that extends over the tip capture spindle to the distal tip assembly.

Abstract: An endovascular stapling apparatus for delivering a staple to a vessel of a patient, including a plurality of clips, a housing, and a rod. Each of the clips includes a bridge and legs that self-transition from a biased state to a natural state in which the legs each form a loop. The housing defines a channel and a window open to the channel. The clips are retained within the channel in the biased state. The rod is slidably disposed within the channel, selectively moves the clips toward and away from the window, and releases the clips from the window.

Abstract: The present invention comprises both a system and a method for mechanically depressing a key of an underlying keyboard in response to a user input. The system preferably comprises a computer system and a mechanical interface device. The mechanical interface preferable mounts on top of the underlying keyboard and preferably includes a three dimensional representational object configured for manipulation by the user. This computer system preferably comprises a processor, a display coupled to the processor, and the underlying keyboard coupled to the processor. The computer system preferably shows a corresponding image in response to manipulation of the three dimensional representational object by the user. By utilizing the three dimensional representational object instead of a keyboard as the user's interface, the present invention gives the user a simpler, more realistic computer interface.

Abstract: A keyboard has a key array including keys, a top surface having a front edge and a back edge, and a bottom surface positioned opposite the top surface. An interface device for use with the keyboard includes a base, a front standoff coupled to the base and having a keyboard-contacting portion, and a back standoff coupled to the base and having a keyboard-contacting portion. The keyboard-contacting portions are spaced such that, when the base is positioned over the key array, the key array is positioned between the keyboard-contacting portions so as to align the base in a front-to-back orientation relative to the key array. The keyboard-contacting portions are both supported by the top surface of the keyboard. The interface device also includes a key-contacting mechanism mounted on the base in a fixed orientation relative to the standoffs, and a coupling mechanism for removably coupling the interface device to the keyboard.
