The present disclosure relates to a bed-integrated electromagnetic field apparatus for controlling movement of a microrobot, and a method for driving a microrobot by using the same. A bed-integrated electromagnetic field apparatus according to the present disclosure can accurately control the movement of a medical device that can be inserted into a human body, such as a microrobot, and enables reduction of the size of the apparatus so as to be used in a medical procedure for diagnosis and treatment of vascular disease and the like.

The present disclosure provides a mounting assembly for attaching medical equipment to a patient table. In one particular embodiment, the present disclosure provides a mounting assembly for attaching a magnetic field generator to a patient table. The mounting assembly allows for the secure attachment of the magnetic field generator to the patient table while also allowing for easy adjustment of the positioning and location of the magnetic field generator, even after the patient is on the table. In many embodiments the mounting assembly is comprised of a mounting apparatus that attaches directly to the patient table and first and second side rails that attach to the magnetic field generator and are configured to slidably attach to the mounting apparatus. In some embodiments, the mounting apparatus and side rails are constructed of a material that provides little or no interference with the magnetic field generator.

The invention relates to a method of simultaneously calibrating magnetic actuation and sensing systems for a workspace, wherein the actuation system comprises a plurality of magnetic actuators and the sensing system comprises a plurality of magnetic sensors, wherein all the measured data is fed into a calibration model, wherein the calibration model is based on a sensor measurement model and a magnetic actuation model, and wherein a solution of the model parameters is found via a numerical solver order to calibrate both the actuation and sensing systems at the same time.

An external actuation device includes a housing, a motor, a driving magnet, a sensor, and a controller. The motor includes a driveshaft that is rotatable about a rotation axis. The driving magnet is rotatably coupled with the driveshaft and is rotatable together with the driveshaft about the rotation axis. The sensor is associated with the driving magnet and is configured to detect a magnetic force between the driving magnet and a driven magnet disposed adjacent to the driving magnet. The controller is in communication with the motor and the sensor.

Some embodiments provide a system for external manipulation of magnetic nanoparticles in vasculature using a remotely placed magnetic field-generating stator. In one aspect, the systems and methods relate to the control of magnetic nanoparticles in a fluid medium using permanent magnet-based or electromagnetic field-generating stator sources. Such a system can be useful for increasing the diffusion of therapeutic agents in a fluid medium, such as a human circulatory system, which can result in substantial clearance of fluid obstructions, such as vascular occlusions, in a circulatory system resulting in increased blood flow.

Described here are devices, systems, and methods for moving and/or supporting an internal organ or other tissue, such as during minimally-invasive surgery. Generally, a system for moving and/or supporting tissue may comprise a magnetic control component and a retractor having at least one magnetic portion. The retractor may have a first low-profile configuration for passing through an incision into a surgical site within a patient and a second expansive configuration for engaging tissue. The magnetic control component may be placed over the surgical site external to the patient and generate a magnetic field to manipulate the retractor and engaged tissue.

A probe for use in an anatomical region of a patient. The probe can optionally include: a proximal portion; an insertion portion and a magnetizable element. The insertion portion can be coupled to the proximal portion and can extend distally thereof. The insertion portion can have an elongated extent and a longitudinal axis. The insertion portion can include a flexible section. The magnetizable element can be positioned at a distal end portion of the insertion portion and can be configured for use within the anatomical region to produce a magnetic force between the magnetizable element and an extracorporeal magnetizable element that can direct the distal end portion of the probe to a desired location within the anatomic region.

A device for environmentally friendly destruction of health-relevant and cosmetically/aesthetically relevant cell structures, in particular tumour cells, which have at least one metallic nanoparticle on their cell membrane, is disclosed. The device includes a primary coil for generating an inhomogeneous primary magnetic field, a secondary coil for generating an inhomogeneous secondary magnetic field and a control device which is designed for actuating the primary coil in such a way that the nanoparticle is deflected by the primary magnetic field and for actuating the secondary coil in such a way that the secondary magnetic field oscillates in relation to the primary magnetic field and deforms it periodically in order to generate Alfvén waves which deflect the nanoparticle, whereby the cell membrane of the cell structure is torn up by the nanoparticle and the cell structure is consequently destroyed.

A system and method for performing surgical procedures within a body cavity, e.g. abdomen, uses a magnetized device is utilized to allow a surgeon to control intra-abdominal organs and objects. The system and method allows a surgeon to perform an intra-abdominal procedure without the need to position surgical tools inside of the body cavity. Additional surgical ports are not necessary as the magnetized device allows the surgeon to retract or position various objects within the abdomen.
