A drug delivery robot is provided. The drug delivery robot comprises: a storage space in which a drug is stored; a first accommodation unit formed at the front of the storage space along a first direction; an outlet by which the first accommodation unit communicates with the outside; a body having a first communication hole by which the storage space communicates with the first accommodation unit; a front rotational magnet which is located in the first accommodation unit and has a central axis arranged in a second direction perpendicular to the first direction; a first fixed magnet which is fixedly coupled to one side of the body in the rear of the front rotational magnet; and a second fixed magnet which is fixedly coupled to the other side of the body while having the storage space between the first fixed magnet and the second magnet and is arranged to face polarities different from those of the first fixed magnet, wherein the front rotational magnet can selectively rotate around an axis of the first direction or the second direction by means of an external magnetic field control, the body rotates together around the axis of the first direction when the front rotational magnet rotates around the axis of the first direction, the front rotational magnet opens or closes the first communication hole by means of the magnetic force with the first fixed magnet and the second fixed magnet when the front rotational magnet rotates around the axis of the second direction.

Disclosed is a catheter system. The catheter system includes: a catheter module including a catheter and a first fastening magnet coupled to a tip of the catheter; and a magnetic robot including a second fastening magnet magnetically coupled to the first fastening magnet, and coupled to and released from the catheter module.

A microrobot is disclosed. The microrobot comprises: a rotating shaft; a main magnet fixed and coupled to the rotating shaft; a first support body which is inserted into the rotating shaft and which is rotatable around the rotating shaft; a first driving magnet which is fixed and coupled to the first support body and which has a magnetic moment differing, in size, from that of the main magnet; and a plurality of first legs coupled to the outer circumferential surface of the first support body.

An extension member is has a body with a proximal end and an opposing distal end. It includes a hollow lumen extending therethrough from the proximal end to the distal end. It has a female luer lock connector proximate its proximal end and a male luer lock connector proximate its distal end. Its body has an outer surface with a driven member.

A robot controller (515) includes a first input (502) configured to receive images (524) from an imaging device for a region of interest. A target identification device (516) is configured to identify a target region in the images. A control system (517) is coupled to a robotically controlled treatment device to generate control signals to control the treatment device to treat the target region when the treatment device is positioned corresponding to the target region. A treatment system comprising an aspiration device, a robot system and a control system, as well as a method for treatment of tissue are also disclosed.

Remotely-controllable internal devices for insertion into a biological lumen and similar spaces within biological organisms; and magnetic systems for remote control thereof. Embodiments include mechanisms for linear motion within a lumen, mechanisms for payload release of therapeutic, diagnostic, and examination materials, and anchoring mechanisms for affixing a device to the outer wall of a lumen for a variety of medical and biological purposes. Related embodiments provide additional features including gradual payload release and reversibly-anchoring mechanisms Different functionalities (motion, payload release, anchoring) are independently-controllable through embodiment configurations featuring differing magnetic force thresholds and orthogonally-oriented magnetic responses.

Described herein are unit cells including a base plate; a top plate; and a lumen extending longitudinally from the base plate to the top plate, the lumen defined by a side wall formed from a plurality of cojoined panels extending between a bottom surface of the top plate and a top surface of the base plate. The unit cell can be magnetically actuatable, such that the unit cell can be reversibly transitioned between a contracted configuration, an extended configuration, or a combination thereof using an applied magnetic field.

Biological navigation devices and methods are disclosed. The devices can be used as or to support colonoscopies or endoscopes. The devices can have longitudinally extensible cells that can be selectively inflated. The devices can have articulable links. The devices can be removably attached to elongated elements, such as colonoscopes or other endoscopes.

A system and method used to deliver an aortic valve therapeutic device, such as a delivery device for an aortic valve replacement, to an aortic valve site. The system 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.

Provided is a stable mounting for a robotic arm, a tool changer for a robotic arm, a motion restrictor for a robotic-arm controlled steerable tool, a dispenser unit for applying a sterile drape over a robotic arm, and a tool radial actuation assembly (TRAA), a robotic arm fitting radial actuation assembly (FRAA).
