Medical Device installation tool and methods of use
First Claim
1. A medical device installation tool, comprising:
- a housing;
a pair of opposed levers, each having a proximal end and a distal end, the proximal end of each lever being moveably coupled to a portion of the housing; and
a prosthesis positioning mechanism, at least a portion of which is disposed between the pair of opposed levers, the prosthesis positioning mechanism being selectively configured such that at least a portion of the prosthesis positioning mechanism translates along a longitudinal axis of the installation tool while maintaining a substantially fixed length of the installation tool.

Abstract
Methods and devices for implanting a prosthetic device, such as an artificial spinal implant, are provided. The installation tool can include a handle having a pair of opposed levers, an optional pusher block disposed between the levers, and a shaft at least partially disposed within the handle and able to be coupled to the pusher block and/or to a prosthetic device. As the shaft translates along a longitudinal axis of the installation tool, the pusher block and/or the prosthetic device separate the levers and distract adjacent vertebral bodies to position a prosthetic device therebetween. The tool is able to maintain its an overall length during use, and it can be configured in rotation and/or translation modes.

17. A medical device installation tool, comprising:
-
a housing;
a shaft coupled to the housing, the shaft being selectively configured to translate along a longitudinal axis of the installation tool and to rotate about the longitudinal axis of the installation tool as a result of manipulation of a single driver; and
a pair of opposed levers, each having a proximal end and a distal end, the proximal end of each lever being pivotably coupled to a portion of the housing such that the distal ends of the levers separate in response to the shaft moving from the proximal end to the distal end. - View Dependent Claims (18, 19, 20, 21)

22. A method for implanting a prosthetic device, comprising:
-
disposing portions of opposed, pivotable levers of an installation tool between vertebral bodies;
linearly translating a shaft along a longitudinal axis of the installation tool to move a prosthetic device between the opposed levers toward the vertebral bodies while causing distal ends of the opposed levers to separate and distract the vertebral bodies while substantially maintaining a length of the installation tool; and
implanting the prosthetic device between the distracted vertebral bodies. - View Dependent Claims (23)
