MRI-GUIDED MEDICAL INTERVENTIONAL SYSTEMS AND METHODS
First Claim
1. A trajectory frame for use with an MRI-guided interventional system, comprising:
- a base having a patient access aperture formed therein, wherein the base is configured to be secured to the body of a patient;
a yoke movably mounted to the base and rotatable about a roll axis; and
a platform movably mounted to the yoke and rotatable about a pitch axis; and
an elongated guide secured to the platform, wherein the guide comprises opposite proximal and distal end portions, wherein the guide distal end portion is positioned proximate the patient access aperture, wherein the guide comprises a bore therethrough that extends from the proximal end portion to the distal end portion, wherein the guide is configured to receive a device within the bore, and wherein the device is removably secured to the guide proximal end portion via a quick release shape and/or component.

Abstract
A trajectory frame for use with an MRI-guided interventional system includes a base having a patient access aperture formed therein. The base is configured to be secured to the body of a patient. A yoke is mounted to the base and is rotatable about a roll axis. A platform is mounted to the yoke and is rotatable about a pitch axis. An elongated guide is secured to the platform and includes opposite proximal and distal end portions and a bore that extends from the proximal end portion to the distal end portion. The guide distal end portion is positioned proximate the patient access aperture. The guide is configured to removably receive various devices therein for quick release therefrom, including a targeting cannula, drill guide and drill bit, skull fixation device and driver, and catheter guide.
