Intramedullary rod implantation system
First Claim
1. A system for implanting a prosthetic device into a bone, the prosthetic device having an opening that is disposed in the bone, the system comprising:
- a plug that is removably received within the opening of the prosthetic device;
a bone removal tool that advances into the bone from outside the bone and that removes a portion of the bone while advancing into the bone to reveal the plug, the bone removal tool including a plug engaging portion that engages with the plug, the bone removal tool at least partially removing the plug from the opening of the prosthetic device while engaged with the plug; and
an alignment system that detects whether the bone removal tool and the plug are substantially axially aligned,wherein the alignment system includes a receiver and a signal generator, one of the receiver and the signal generator being positioned within the plug.

Abstract
A system for implanting a prosthetic device with an opening into a bone includes a plug that is removably received within the opening of the prosthetic device. The system also includes a bone removal tool that advances into the bone from outside the bone and that removes a portion of the bone while advancing into the bone to reveal the plug. The bone removal tool includes a plug engaging portion that engages with the plug. The bone removal tool at least partially removes the plug from the opening of the prosthetic device while engaged with the plug. Moreover, the system includes an alignment system that detects whether the bone removal tool and the plug are substantially axially aligned.

14. A system for implanting a prosthetic device into a bone comprising:
-
an intramedullary (IM) rod that is operable to be implanted in an IM canal of one of a femur, a tibia, and a humerus, the IM rod having a longitudinal axis and a through hole that extends transverse to the longitudinal axis; a plug that is threadably engaged to the IM rod within the through hole in a first rotational direction; a bone removal tool that rotates in a second rotational direction, the second rotational direction being opposite the first rotational direction, the bone removal tool advancing into the bone from outside the bone in a first linear direction, the bone removal tool removing a portion of the bone while rotating in the second rotational direction and while advancing through the bone in the first linear direction to reveal the plug, the bone removal tool including a barb that embeds within and engages with the plug, the bone removal tool at least partially threadably disengaging the plug from the through hole of the IM rod while rotating in the second rotational direction and while embedded within the plug; an alignment system that detects whether the bone removal tool and the plug are substantially axially aligned, the alignment system including at least one of an ultrasound system and a proximity sensor system, the alignment system including a power generating device that generates power from rotation of the bone removal tool to power the alignment system; a feedback device that indicates that the bone removal tool is substantially axially aligned with the plug; and a fastener that extends into the bone and into the opening to secure the intramedullary rod to the bone. - View Dependent Claims (15, 16, 17)

18. A system for implanting a prosthetic device into a bone, the prosthetic device having an opening that is disposed in the bone, the system comprising:
-
a plug configured to be removably received within the opening of the prosthetic device, the plug including a signal generator positioned within the plug and configured to emit a radio frequency signal; a bone removal tool configured to pass into the bone relative to the plug, the bone removal tool including a plug engaging portion configured to engage the plug to at least partially remove the plug from the opening of the prosthetic device while engaging the plug; and an alignment system that detects whether the bone removal tool and the plug are substantially axially aligned, the alignment system including a receiver that receives the radio frequency signal from the signal generator associated with the plug and a processor that detects whether the bone removal tool and the plug are substantially axially aligned based on the radio frequency signal received by the receiver. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
