Abstract

A medical instrument includes a flexible catheter and a catheter accessory device. The catheter has a distal end insertable within a body lumen of a patient. The device is slidably engagable with the catheter. One of the catheter and the device includes magnetic material, and the other of the catheter and the device includes electrically-energizable windings. The catheter and the device are adapted to operate as a linear motor wherein controllably electrically energizing the windings while immobilizing one of the catheter and the device slidingly moves the other of the catheter and the device. A method for using the medical instrument, wherein the medical instrument also includes a controller operatively connected to the windings, includes inserting the distal end within the body lumen, immobilizing one of the catheter and the device, and activating the controller to advance the other of the catheter and the device within the body lumen.

Description

technical field [0001] The present invention relates generally to medical devices, and more particularly to medical devices having catheters and catheter assist devices and methods of using the same. Background technique [0002] Examples of known catheters include, but are not limited to, flexible insertion tubes for endoscopes, including those for colonoscopes and enteroscopes. The insertion tube has an articulatable distal portion controlled by wires extending from the distal portion to a control knob on the endoscope handle. A wide-angle camera in the distal end of the insertion tube allows for medical observation. In use, the distal end of the insertion tube is inserted into a body cavity of a patient. The user manually pushes the proximal tube portion to advance the distal end of the insertion tube in the body cavity for medical observation and / or medical treatment. In a tortuous body lumen, such as the colon, the articulable distal end of the insertion tube may bec...
