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.

The present disclosure describes kits for surgical repair of soft tissue defects, including hernias. The kits include any combination of components selected from an implantable sheet, at least one loop tie, a delivery tool, a positioner, a rolling device, and a insertion member. Packaging for the kits and/or components and methods of using the kits and/or components are also provided.

A system for the physical manipulation of free magnetic rotors in a circulatory system using a remotely placed magnetic field-generating stator is provided. In one embodiment, the invention relates to the control of magnetic particles 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. Examples of vascular occlusions targeted by the system include, but are not limited to, atherosclerotic plaques, including fibrous caps, fatty buildup, coronary occlusions, arterial stenosis, restenosis, vein thrombi, arterial thrombi, cerebral thrombi, embolisms, hemorrhages, other blood clots, and very small vessels.

A method has been invented for intravenously inserting a tumor reduction radiation emitter into the body of a patient suffering from a cancerous tumor. The emitter is very small, yet detectable by medical imaging techniques and guidable by use of magnetism. The emitter is guided through the body by use of a magnet until it is adjacent or in in the tumor itself. The emitter can be oriented in various desired directions by the magnet. The emitter is then wirelessly powered by electrical induction, causing the radiation of a desired wavelength to be directed to tumor cells, causing tumor reduction.

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.

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.

A guidance apparatus includes: a magnetic field generator configured to generate a magnetic field that acts on a magnet; a magnetic field shielding material configured to shield the magnetic field generated by the magnetic field generator; an operation input device configured to receive an input of at least one of a target position and a target posture for guiding a position and a posture of a capsule medical apparatus; and a controller configured to control the magnetic field generator to generate a magnetic field that has been corrected to offset or reduce a deviation amount of the position or the posture of the capsule medical apparatus with respect to the target position or the target posture, caused by distortion, due to the magnetic field shielding material, of a magnetic field for guiding the capsule medical apparatus to at least one of the target position and the target posture.

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.
