Abstract: An MRI-compatible catheter includes an elongated flexible shaft having opposite distal and proximal end portions. A handle is attached to the proximal end portion and includes an actuator in communication with the shaft distal end portion that is configured to articulate the shaft distal end portion. The distal end portion of the shaft may include an ablation tip and includes at least one RF tracking coil positioned adjacent the ablation tip that is electrically connected to an MRI scanner. The at least one RF tracking coil is electrically connected to a circuit that reduces coupling when the at least one RF tracking coil is exposed to an MRI environment. Each RF tracking coil is a 1-10 turn solenoid coil, and has a length along the longitudinal direction of the catheter of between about 0.25 mm and about 4 mm.

Abstract: An MRI-guided interventional system for use with a patient and an interventional device includes a base, a trajectory guide frame, and a mounting device. The base is configured to be secured to a body of the patient. The trajectory guide frame includes a targeting cannula. The targeting cannula has an elongate guide bore extending axially therethrough, defining a trajectory axis, and being configured to guide placement of the interventional device. The trajectory guide frame is operable to move the targeting cannula relative to the base to position the trajectory axis to a desired intrabody trajectory to guide placement of the interventional device in vivo. A plurality of patient engagement structures are provided on the base and are configured to penetrate tissue of the body and to space the base apart from the tissue. The system further includes a plurality of fasteners configured to secure the base to the body.

Abstract: Devices for transferring fluid to or from a subject include an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen. The devices also include an elongate needle having opposing proximal and distal ends. The elongate needle is configured so that the distal end of the needle extends out of the distal end of the cannula a suitable adjustable distance. The devices also include a housing with a length adjustment mechanism that adjusts a length between the tip of the needle and the distal end of the tubular cannula.

Abstract: An MRI-compatible tip assembly for an MRI-compatible medical device includes a first tubular member, a second tubular member, a ring electrode, and a tip electrode. The tip electrode proximal end is secured to the first tubular member distal end. The second tubular member distal end is inserted through the ring electrode and is secured to the first tubular member proximal end. When assembled, the tip assembly is a substantially rigid structure. Each tubular member has a recessed portion for a tracking coil.

Abstract: An MRI-compatible catheter that reduces localized heating due to MR scanner-induced currents includes an elongated flexible shaft having a distal end portion and an opposite proximal end portion. A handle is attached to the proximal end portion and includes an electrical connector interface configured to be in electrical communication with an MRI scanner. One or more RF tracking coils are positioned adjacent the distal end portion of the shaft. Each RF tracking coil includes a conductive lead, such as a coaxial cable, that extends between the RF tracking coil and the electrical connector interface and electrically connects the RF tracking coil to an MRI scanner. In some embodiments of the present invention, the conductive lead has a length sufficient to define an odd harmonic/multiple of a quarter wavelength of the operational frequency of the MRI Scanner, and/or includes a series of pre-formed back and forth segments along its length.
