CANCELLOUS BONE DISPLACEMENT SYSTEM AND METHODS OF USE
First Claim
Patent Images
1. A bone displacement assembly adapted for preparing soft bone comprising:
- a cannula adapted for percutaneously accessing a target tissue within a bone body, having a tubular elongate body and a handle; and
a probe having a handle assembly and an elongate body;
the elongate body adapted for slidable insertion and removal from the cannula, the elongate body having a longitudinal axis and a distal tip adapted for displacing soft bone;
the handle assembly adapted for precise control of the distal tip, said handle assembly comprising a connection portion, a tip rotation control and a tip translation control;
the connection portion adapted to removably attach to the cannula handle, the tip rotation control adapted to independently rotate the distal tip substantially about the longitudinal axis and the tip translation control adapted to independently translate the distal tip substantially along the longitudinal axis.

Abstract
A bone displacement assembly for use during a medical procedure including preparing soft bone includes a cannula and a probe that is removably inserted into the cannula. The probe includes a curved tip designed to mechanically displace soft bone and to prepare the bone tissue for subsequent treatment such as cement injection. The probe also includes a handle assembly that connects with the cannula and also includes one control device for independently rotating the distal tip and a second control device to independently translate the distal tip.

14. A soft bone displacement and treatment system comprising:
-
a cannula; a stylet adapted to fit within and be removed from said cannula; a probe having a handle assembly and an elongate body; the probe elongate body adapted for slidable insertion and removal from the cannula, having a longitudinal axis, and a distal tip adapted for displacing soft bone; the handle assembly adapted for precise control of the distal tip, said handle assembly having a connection portion, a tip rotation control and a tip translation control; the connection portion adapted to removably attach to the cannula handle, the tip rotation control adapted to independently rotate the distal tip about the longitudinal axis and the tip translation control adapted to independently translate the distal tip along the longitudinal axis; and a settable implant injection delivery system having a connector adapted to fluidly connect the delivery system to the cannula.

18. A medical procedure to be performed on a bone body comprising:
-
providing a bone displacement assembly including a cannula having a tubular member and a handle, and a probe having a handle assembly and an elongate body with a distal tip; penetrating the target tissue with the cannula; inserting the probe elongate body through the cannula and into the target tissue; attaching the probe handle assembly to the cannula handle; independently translating probe distal tip to displace cancellous bone; independently rotating probe distal tip to displace cancellous bone; withdrawing the probe elongate body; and treating the target tissue. - View Dependent Claims (19, 20, 21)
