An insertion device includes a long and thin insertion section, a rotating housing that is provided to be rotatable about a longitudinal axis, a drive shaft that is connected to a motor rotating the rotating housing, and that transmits a rotation of the motor, a rotor that is provided at a distal-end side of the drive shaft and that is provided to be movable in relation to the rotating housing in axial direction of the insertion section, and that transmits the rotation to the rotating housing via a coating of the insertion section, a sensor that detects that the rotor moves a predetermined amount in either forward or backward direction relative to the axial direction of the insertion section, and a control unit that controls, according to the detection by the sensor, a state of the motor including a positive rotation, a negative rotation, and rotation halt.

Devices, systems, and methods are disclosed that help deliver catheters or other medical devices to locations within a patient's body. The device includes a transporter catheter having a proximal end and a distal end, at least a first balloon located at the distal end, substantially at a tip of the transporter catheter, and at least a second balloon located between the distal end and the proximal end of the transporter catheter. The first balloon is an orienting balloon and the second balloon is an anchor balloon. The transporter catheter may include a single lumen or more than one lumen. The transporter catheter may include a shaft including an inner layer and an outer layer, the inner layer may be made of a material more flexible than the material of the outer layer. The outer layer may also include a braided-wire assembly, said braided-wire assembly being formed by braiding a plurality of flat wires or circular wires. The braided-wire assembly may wrap around the inner layer. The transporter catheter may include a shaft that may include a plurality of segments of varying degrees of hardness. The degree of hardness of the segment of the shaft of the transporter catheter located between the first balloon and the second balloon may be less than the degree of hardness of the segment of the shaft between the second balloon and the proximal end of the catheter.

A system includes a flexible guide tube, an actuator coupled to the flexible guide tube and configured to move at least a portion of the flexible guide tube, a processor, and memory storing computer-executable instructions. When executed by the processor, the computer-executable instructions cause the system to: identify at least one factor associated with insertion or removal of a tool configured to be inserted through or removed from the flexible guide tube; identify, in a first configuration of the flexible guide tube and based on the at least one factor, one or more sections of the flexible guide tube having one or more bends that the tool cannot traverse; and command the actuator to automatically move the flexible guide tube to a second configuration without manual steering by a user, wherein the second configuration does not include the one or more bends that the tool cannot traverse.

A vascular intervention robot includes a catheter rotation unit for rotating a catheter on an axis parallel to a longitudinal direction of the catheter, a guide wire rotation and supply unit that is provided at one side of the catheter rotation unit and that is provided for transferring a guide wire in a longitudinal direction of the guide wire and for rotating the guide wire on an axis parallel to the longitudinal direction of the guide wire in a state in which the guide wire is inserted in the catheter, a transfer unit for transferring the catheter rotation unit and the guide wire rotation and supply unit in the longitudinal direction of the catheter, and an expanding and contracting unit that is provided at another side of the catheter rotation unit and that is expandable and contractible along the longitudinal direction of the catheter while supporting the catheter when the transfer unit transfers the catheter rotation unit and the guide wire rotation and supply unit in the longitudinal direction of the catheter.

A system and method used to deliver an aortic valve therapeutic device to an aortic valve site includes a cable percutaneously introduced a cable into a vasculature of a patient and positioned to run from a femoral vein, through the heart via a transseptal puncture, and to a femoral artery. The therapeutic device is passed over an end of the cable at the venous side and is secured to the cable. The therapeutic device is pushed in a distal direction while the second end of the cable is pulled in the proximal direction to advance the therapeutic device to the mitral valve site. A left ventricle redirector aids in orienting the therapeutic device and preventing migration of the cable towards delicate mitral valve structures and chordae tendoneae during advancement of the therapeutic device.
