System and methods for advancing a catheter
First Claim
1. An advancer system for moving an elongate medical device within a body, the system comprising:
- a drive unit having a motor, and having a mover for the medical device that is configured to initially receive any portion along the length of the medical device, and to removably attach to the medical device in a manner such that the mover can be attached to the medical device at any point along the length of the medical device, to permit removal, adjustment and reattachment of the medical device, the drive unit configured to translate movement of the motor to the device so as to alternately advance and retract the device relative to the body; and
a user-operable control system configured to control the drive unit.

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.

11. An advancer system for moving an elongate medical device, such as a catheter within a body, the system comprising:
-
a drive unit comprising a motor, the drive unit configured to translate movement of the motor to the device so as to move the device relative to the body, and configured to successively advance and retract the medical device a minimum distance in a repetitive manner when the advancer system is idling, so as to reduce static friction between the medical device and tissues surrounding the medical device; a control system configured to control the drive unit; and wherein the control system is operable by a user remote from a procedure site in which the body is positioned. - View Dependent Claims (12, 13, 14, 15, 16)

17. An advancer for moving an elongate medical device, the advancer comprising:
-
a base having a slot with an open top and opposed sides therein; a pair of opposed wheels on opposite sides of the slot to engage an elongate medical device; a drive mechanism adapted to be connected to a motor, for turning at least one of the pair of opposed wheels, the drive mechanism being configured to successively advance and retract the medical device a minimum distance in a repetitive manner when the advancer system is idling, so as to reduce static friction between the medical device and tissues surrounding the medical device; a cover movably mounted on the base for movement between a loading position in which the top of the slot is open to allow a portion of the elongate medical device intermediate the ends to be inserted into the slot between the wheels, and a drive position in which the cover at least partially blocks the top of the slot to retain the medical device therein. - View Dependent Claims (18, 19, 20)
