A method for tracking movement of a movable portion of an interventional device disposed within a natural or artificial body opening is provided. In particular, image data of fiducials is acquired and therefrom an initial position of an interventional device movable portion with respect to a given coordinate system is determined. Next, real time position data from the encoders is acquired as the movable portion is moved from the initial position, and a displaced position from the initial position is determined. From this acquired information, a position of the movable portion in the coordinate system is determined using both the initial position as determined from the image data and the real time displaced position as determined from the encoders.

Method for insertion of a medical device within a body during a medical imaging process

The end-effector includes a sheath and a medical device or needle carrier that is disposed within the interior compartment of the sheath. An aperture is located in a portion of the sheath proximal a distal end of the sheath that is inserted into a natural or artificial cavity. This device is guided by a real-time imager.

The end-effector () includes a sheath () and a medical device or needle carrier () that is disposed within the interior compartment () of the sheath. Aperture () is located in a portion of the sheath proximal a distal end of the sheath that is inserted into a natural or artificial cavity. This device is guided by a real-time imager.

A device, system, and method for entering a medical device such as a needle into the body inside a medical imager such as a MRI scanner, CT, X-ray fluoroscopy, and ultrasound imaging, from within a body cavity (such as the rectum, vagina, or laparoscopically accessed cavity). A three degree-of-freedom mechanical device translates and rotates inside the cavity and enters a needle into the body, and steers the needle to a target point selected by the user. The device is guided by real-time images from the medical imager. Networked computers process the medical images and enable the clinician to control the motion of the mechanical device that is operated within the imager, outside of the imager or remotely from outside the imager.

Apparatus for insertion of a medical device within a body during a medical imaging process

Herein is disclosed a probe, including a first electrode disposed at least partially on the probe surface, a second electrode disposed at least partially on the probe surface, a first conductor electrically coupled to the first electrode, a second conductor electrically coupled to the second electrode, and a reactive element electrically coupling the first conductor and the second conductor.

Systems and methods for magnetic-resonance-guided interventional procedures

Featured is a system to determine the three-dimensional position and orientation of an effector (a needle, probe, or other medical instrument) relative to a subject using cross-sectional images (e.g. from a CT or MRI scanner). Also provided is a method for image guided effector placement that requires no immobilization of the patient or fiducial implantation. A localization module (fiducial object) is integrated or associated with the effector allowing for the localization of the effector in the image space using a single cross-sectional image.
