Abstract: A system and medical device for the electromagnetic tracking of a medical instrument transported through the medical device. The medical device has a central axis and a channel that receives and transports a medical instrument through the medical device. The channel extends to a distal portion of the medical device and connects with an opening in the medical device that is not aligned with the central axis. The medical device includes a tracking component that is a plurality of coordinated electromagnetic sensors for generating a virtual axis of travel for the medical instrument, with the virtual axis passing through the opening of the device and being aligned with tool insertion axis.

Abstract: An instrument driving mechanism includes an instrument drive assembly (140) including a first set of wheels (136) coupled to a first end portion and a second set (138) of wheels coupled to a second end portion opposite the first end portion. The first set of wheels is configured to engage an elongated instrument (104) therein such that a rotation plane of the first set of wheels is coplanar with a longitudinal axis of the instrument. The second set of wheels is configured to engage the elongated instrument therein such that a rotation plane of the second set of wheels is obliquely oriented with the longitudinal axis of the instrument wherein motion of the instrument is controlled by controlling rotations of the wheels. The instrument drive assembly mounts to a mounting position (149) of a medical device that permits the instrument to pass therethrough and is configured to fix a position of the instrument drive assembly to enable positioning of the instrument.

Abstract: A pre-curved steerable catheter includes a catheter body (102) having a distal end portion. The distal end portion includes a permanently curved flexible end portion (110). A pull wire (108) is disposed in a pull wire lumen within the catheter body. The pull wire extends from the distal end portion to a proximal end portion of the catheter body wherein the pull wire, when tensioned, provides a change in an angle of the curved flexible end portion of the catheter body.
