Abstract

An MRI-guided interventional system includes a frame (100) with a cooperating targeting cannula (200). The frame is configured to be secured to the body of a patient, and is configured to translate and rotate such that the targeting cannula can be positioned to a desired intrabody trajectory. The frame may include one or more MRI-visible fiducial markers that allow frame location/orientation to be determined within an MRI image. A plurality of user-activatable actuators (140a, 14Od) are configured to translate and rotate the frame relative to the body of a patient so as to position the targeting cannula to a desired intrabody trajectory. The targeting cannula includes an axially-extending guide bore therethrough that is configured to guide placement of an interventional device in vivo. Various instrumentation and equipment, such as stimulation leads, ablation catheters, injection catheters, etc., can be inserted through the targeting cannula to execute diagnostic and/or surgical procedures.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Patent Application No. 60 / 933,641, filed June 7, 2007, and U.S. Provisional Patent Application No. 60 / 974,821, filed September 24, 2007, the disclosures of which are incorporated by reference Incorporated herein in its entirety. technical field [0003] The present invention relates generally to medical systems and methods, and more particularly to in vivo medical systems and methods. Background technique [0004] Deep brain stimulation (DBS) is becoming an accepted modality for neurosurgical treatment of patients suffering from chronic pain, Parkinson's disease or convulsions, and other medical conditions. Other electrical stimulation treatment protocols utilizing internal stimulation of the sympathetic chain and / or spinal cord and the like have been performed or proposed. An example of a prior art DBS system is the system. The system includes an implantable pulse generator stimu...
