Reducing incremental measurement sensor error

For position sensors, e.g., a fiber-based system, that build a shape of an elongated member, such as a catheter, using a sequence of small orientation measurements, a small error in orientation at the proximal end of the sensor will cause large error in position at distal points on the fiber. Exemplary methods and systems are disclosed, which may provide full or partial registration along the length of the sensor to reduce the influence of the measurement error. ... Hansen Medical Inc

Active drive for guidewire manipulation

A guidewire manipulation system may include a cylindrical drum, having a cylindrical outer drum surface with a helical groove for housing a flexible guidewire and an anchoring mechanism for attaching the flexible guidewire to the drum. The system may also include an outer shell or belt disposed around the drum, forming an opening through which the flexible guidewire exits. ... Hansen Medical Inc

Steerable catheter with shaft load distributions

A steerable catheter system may include a flexible elongate catheter body, a drive mechanism at the proximal end of the catheter body, and at least one group of pullwires extending along a length of the catheter body. The catheter body may include a distal articulating section and a proximal non-articulating section. ... Hansen Medical Inc

System and methods for tracking robotically controlled medical instruments

Systems and methods are described herein for tracking an elongate instrument or other medical instrument in an image.. . ... Hansen Medical Inc

Catheter driver system

An apparatus for performing medical procedures on an anatomical body includes an extension with an element near its distal end to be extended into the body, and a driver that moves the extension axially into the body, and that causes flexure of the distal end of the extension. The movement and flexure of the extension is driven by the driver from the proximal end of the extension, and an electronic controller directs the operation of the driver.. ... Hansen Medical Inc

Robotic catheter system

A robotic catheter system includes a controller with a master input device. An instrument driver is in communication with the controller and has a guide instrument interface including a plurality of guide instrument drive elements responsive to control signals generated, at least in part, by the master input device. ... Hansen Medical Inc

Torque-based catheter articulation

A robotic surgical system configured for the articulation of a catheter comprises an input device, a control computer, and an instrument driver having at least one motor for displacing the pull-wire of a steerable catheter wherein the control computer is configured to determine the desired motor torque or tension of the pull-wire of a catheter based on user manipulation of the input device. The control computer is configured to output the desired motor torque or tension of the pull-wire to the instrument driver, whereby at least one motor of the instrument driver implements the desired motor torque to cause the desired pull-wire tension to articulate the distal tip of the catheter. ... Hansen Medical Inc

Systems and methods for localizing, tracking and/or controlling medical instruments

Systems and methods are described herein for tracking, localization or controlling an elongate instrument or other medical instrument in an image or patient.. . ... Hansen Medical Inc

Robot-assisted driving systems and methods

Systems and methods for driving a flexible medical instrument to a target in an anatomical space with robotic assistance are described herein. The flexible instrument may have a tracking sensor embedded therein. ... Hansen Medical Inc

This disclosure covers various concepts to use for obtaining measurement of tension in catheter pullwires to improve controllability of a robotic surgical system.. . ... Hansen Medical Inc

Integrated catheter and guide wire controller

A device may operate a guide wire and be operable by a single operator digit. The device may include an insertion control device for advancing the guide wire in a forward and in a reverse direction and along a longitudinal axis of the guide wire; and a rotary device for rolling a guide wire about the longitudinal axis. ... Hansen Medical Inc

Vascular remote catheter manipulator

A robotic instrument driver for elongate members includes a first elongate member, and at least one manipulator mechanism configured to manipulate the first elongate member, and at least one articulating drive configured to articulate the first elongate member, positionable on a bed and beside a patient access site. The manipulator and articulating drive are positioned relative to each other a distance less than the insertable length of the first elongate member, stationary in position.. ... Hansen Medical Inc

Input device for controlling a catheter

An input device includes a plurality of orientation blocks each representing a portion of a catheter assembly and a controller configured to determine an orientation of the plurality of orientation blocks relative to one another. The controller is further configured to output a control signal that causes a tip of a catheter assembly to adopt the orientation determined by the controller. ... Hansen Medical Inc
