Certain aspects relate to systems, devices, and techniques for clot manipulation and removal. At least some of the devices for clot manipulation and removal can be robotically controlled. These devices can include one or more elongate members that can be robotically driven through a patient's vasculature. One such device can include a first elongate member that can serve as an access sheath, a second elongate member that can serve as a clot removal catheter, a third elongate member that can serve as a clot disruptor, and a fourth elongate member that can serve as a guidewire.

A surgical end effector may comprise first and second jaw members. The second jaw member may comprise an offset proximal supply electrode that is positioned to contact an opposing member of the first jaw member when the first and second jaw members are in the closed position. The second jaw member may also comprise a distal supply electrode that is positioned distal of the offset proximal electrode and is aligned with a conductive surface of the first jaw member when the first and second jaw members are in the closed position. When the first and second jaw members are in the closed position, the proximal supply electrode may be in contact with the opposing member and the distal supply electrode is not in contact with the conductive surface of the first jaw member.

A magnetic robot system is provided. The magnetic robot system comprises: a catheter having a first magnet coupling part provided at the front end thereof; and a mobile robot having a second magnet coupling part provided at the rear end thereof, and having a driving magnet, wherein the mobile robot is coupled to the catheter by means of magnetic force between the first magnet coupling part and the second magnet coupling part, and the magnetic force coupling of the first magnet coupling part and the second magnet coupling part can be released by rotating magnetic torque generated by the driving magnet because of the application of external rotating magnetic force.

A transseptal needle or punch is described wherein the distal end of the transseptal needle is able to articulate laterally out of the longitudinal axis of the steerable transseptal needle. The transseptal needle includes a blunted distal end configuration that is minimally traumatic. Under control by the user or a computer, the transseptal needle can be articulated to generate various curves with high bending force. The transseptal needle is configured for use with an introducer which can also include side windows.

The present invention relates to a method, such as a surgical method for assisting a surgeon for placing screws in the spine using a robot attached to a passive structure. The present invention also related to a method, such as a surgical method for assisting a surgeon for removing volumes in the body of a patient using a robot attached to a passive structure and to a device to carry out said methods. The present invention further concerns a device suitable to carry out the methods according to the present invention.

The present invention provides a robotic locomotive device (1) that is capable of driving itself forwards and backwards, anchoring and steering itself whilst inside a tubular structure (200), for example, the human colon, or any structure comprising two opposing walls (202, 204). In this respect, the device is made up of two or three segments (102, 104, 106) covered in an elastic material and driven by an internal actuating mechanism. All of the segments (102, 104, 106) have a concertina configuration that enable a shortening and lengthening motion. As well as contracting and extending in length, at least one of the end segments (102, 106) is capable of bending at an angle away from the longitudinal axis such that it becomes wedged or jammed between the walls (202, 204) of the tubular structure (200). That is, the end segments (102, 106) are capable of both a bending action and a contracting and extending action. The device (1) moves by alternately jamming a segment (102, 104, 106) between the walls (202, 204) of the tubular structure (200), and then contracting or extending the segments (102, 104, 106) to inch the device (1) forward with a more effective locomotive action. As such, the present invention provides a simplified design that is more robust to harsh or unclean environments, whilst still maintaining the level of performance required from such a device.

The invention relates to a magnetic-field driven colloidal microbot that employs wall-based propulsion, method of forming the microbot and a method of using the microbot. The microbot can be formed in situ with the use of magnetic fields, and the magnetic fields can be used to translate the microbot to a specified location in a patient. The microbot does not depend on swimming or flow currents within a patient to move, but instead can propel itself along a surface using a magnetic field. Once the magnetic field is removed, the microbot disassembles into colloidal particles.

A system for surgical planning and assessment of spinal pathology or spinal deformity correction in a subject, the system comprises a control unit configured to align one or more vertebral bodies of a biomechanical model to one or more vertebral bodies of the radiograph. The control unit is configured to receive one or more spinal correction inputs. The control unit is configured to, based on the received one or more spinal correction inputs, simulate the biomechanical model in a predetermined posture. The control unit is configured to provide for display one or more characteristics of the simulated biomechanical model.
