Publication number: 20120083866Abstract: An implantable lead is provided with at least one extendable member to position therapy delivery elements, which may be electrodes or drug delivery ports, after the lead has been inserted into the body. The lead may formed as a resilient element which is contained in a retainer tube that may be removed to permit the lead to deploy. Alternatively, a non-resilient lead may be provided with a slotted retainer tube. A series of mechanical linkages for expanding and retracting the lead within the human body may be actuated with various mechanisms. A control system may be provided for closed-loop feedback control of the position of the extendable members. The invention also includes a method for expanding an implantable lead in situ.Type: ApplicationFiled: December 14, 2011Publication date: April 5, 2012Applicant: Medtronic, Inc.Inventors: Gary W. King, Mark T. Rise, Michael J. Schendel, Richard Schallhorn

Patent number: 7925328Abstract: A stereotactic navigation system for navigating an instrument to a target within a patient may include a stereotactic head frame, an imaging device, a tracking device, a controller and a display. The stereotactic head frame is coupled to the patient and is used to assist in guiding the instrument to the target. The imaging device captures image data of the patient and of the stereotactic head frame. The tracking device is used to track the position of the instrument relative to the stereotactic head frame. The controller receives the image data from the imaging device and identifies the stereotactic head frame in the image data and automatically registers the image data with navigable patient space upon identifying the stereotactic head frame, while the display displays the image data.Type: GrantFiled: December 17, 2007Date of Patent: April 12, 2011Assignee: Medtronic Navigation, Inc.Inventors: Steven Urquhart, Richard Schallhorn
