The invention provides improved instruments and related methods for percutaneously delivering a revision implant to a surgical site in a spine of a patient having an existing implant installed therein. In one aspect, a percutaneous delivery instrument is provided with an inner shaft with a threaded portion at its distal end to engage a percutaneous revision implant, an outer sleeve with a hollow cavity, hinges, and features to engage the percutaneous revision implant at its distal end, and a translator in which the outer sleeve is disposed. The percutaneous delivery instrument may be employed to deliver and install a percutaneous revision implant to extend the existing implant such that it spans additional portions of the spine.

Instrument for percutaneously delivering a percutaneous revision implant

A percutaneous revision implant for percutaneously revising an existing implant located in the spine of a patient may include, for example, extending the existing implant construct to span additional portions of the spine of the patient. The percutaneous revision implant comprises a proximal end portion and a distal end portion. The proximal end portion comprises a connector having two opposable walls joined at one end to define a cavity having a first longitudinal axis. The cavity is suitable to receive and engage a rod of the existing implant. The percutaneous revision implant of the invention permits a medical practitioner to extend an existing implant construct without significantly disrupting or removing the existing implant or its component parts. A method of using same is also provided.
