Publication number: 20120130387Abstract: An insertion handle for medical implants includes a handle with an elongate shaft extending therefrom and connection means for the implant disposed at the end of the shaft opposite the handle. The connection means includes a pivotable attachment for the implant that is controlled remotely from the handle. Both angle of the implant with respect to the handle and shaft as well as the attachment may be separately controlled and adjusted. Remote angular adjustment facilitates insertion of implants in to small surgical sites because the orientation of the implant may be repeatedly, remotely adjusted as the implant is inserted. Connectors may also be provided at the engagement surface between the handle and implant in order to provide communication with the implant or surgical site. The connectors also may serve as torque bearing members to avoid the need for separate torque bearing means such as keyways and the like.Type: ApplicationFiled: April 15, 2010Publication date: May 24, 2012Applicant: COALIGN INNOVATIONS, INC.Inventors: Philip J. Simpson, George A. Mansfield, Damien J. Shulock, David G. Matsuura, Walter Dean Gillespie, John E. Ashley
