Abstract: A system for moving an elongate medical device has at least one drive element for engaging and moving an elongate medical device. Various embodiments provide for moving the separate inner and outer elements of a telescoping medical device. Some systems also provide for the rotation of a rotatable distal element on a rotatable medical device or the rotation of extension element in a telescoping medical device.

Abstract: A guide for controlling the orientation of a medical device includes a cannula having a lumen therein for the medical device, and a guide member having a passage therein for receiving and directing the medical device, the guide member being movably mounted in the cannula for movement. The guide member can be magnetically responsive to an externally applied magnetic field, or can be magnetically responsive to an externally applied magnetic field when a magnetic medical device is in the passage, and/or it can be mechanically responsive.

Abstract: An advancer system is described for moving an elongate medical device within a body. The system includes a drive unit having a motor. The drive unit is configured to translate movement of the motor to the device so as to alternately advance and retract the device relative to the body. The advancer system also includes a user-operable control system configured to control the drive unit. The control system can interface with a magnetic navigation system. The above-described system allows an operating physician to control catheter advancement and retraction while remaining outside an x-ray imaging field. Thus the physician is freed from repeated x-ray exposure.

Abstract: A deflection mechanism for selectively inducing a bend in a catheter body includes an elongated deflection wire extending within a deflection lumen of the catheter body and into a handle. A guide track is formed within the handle and a thumb wheel is mounted proximal to the elongated guide track within the handle and supports a pinion gear; the thumb wheel and the pinion gear are adapted to be rotated about a common thumb wheel axis, which extends substantially perpendicular to the longitudinal axis. A rack arm extends obliquely to the longitudinal axis of the handle and includes runners received by the guide track, an attachment point coupling the deflection wire to the rack arm and a linear rack engaging the pinion gear. Rotation of the thumb wheel in a first direction draws the deflection wire proximally through the deflection lumen.
