Microanchors for knotless tissue repair

A knotless anchor for attachment of tissue to bone includes a rigid anchor body and a suture extending there from. The suture is hollow and includes a fixed limb portion secured to the rigid anchor body. A soft suture tunnel extends in a longitudinal direction through the fixed limb portion of the suture. A free suture limb is passed through the tissue, back to the anchor, and through the soft suture tunnel, thereby creating a closable suture loop around the tissue. Tension applied to the free suture limb closes the suture loop, and approximates the tissue to the anchor body. When the anchor is deployed in a bone hole, external features of the anchor body grip the walls of the bone hole and simultaneously compress the suture, thereby preventing tissue pull-out. Anchor assemblies and methods of tissue fixation are also disclosed.

CONTROLLING MOTION OF MAGNETICALLY-DRIVEN MICROSCOPIC PARTICLES

Devices, systems and methods for controlling motion of magnetic-driven nanobots are provided. Based on a selection indicative of a pattern of movement of the nanobots (200), a signal can be generated indicative of a pattern of magnetic field to be produced. Electrical signals can be generated to cause production of the pattern of magnetic field. The electrical signals can be provided to a device (300, 800) which is adaptable for being placed on the head or around a tooth of the patient. A first coil (502, 602, 804) of the device can receive the electrical signals and produce the pattern of the magnetic field to drive the magnetically-driven nanobots from a pulp region of the tooth into the dentinal tubules.

Micro robot and micro robot behavior measurement system

A micro robot that is moveable in a body includes first quantum dots.

SURGICAL TOOL FOR ROBOTIC SURGERY AND ROBOTIC SURGICAL ASSEMBLY

A medical instrument for surgery includes at least one frame and at least one jointed device. The jointed device includes at least one first joint member, or first link, adapted to connect to at least one portion of the frame and at least one second joint member, or second link. The first joint member is connected by a rotational joint to the second joint member. The medical instrument includes at least a pair of tendons, adapted to move the second joint member with respect to the first joint member. Each of the first joint member and the second joint member includes a main structural body made in a single piece with one or more convex contact surfaces. Each of the convex contact surfaces is a ruled surface formed by straight line portions all parallel to each other and substantially parallel to a joint movement axis.

System and method of printing 3D biostructures

A computer-implemented method of internally printing a biostructure on a damaged area of a patient. The method includes: assembling a first bioprinter capsule and a first cartridge capsule to form an assembled bioprinter internally within the patient based, at least in part, on directing one or more magnetic fields towards a first bioprinter capsule and a first cartridge capsule, moving the assembled bioprinter to the internally damaged area of the patient based, at least in part, on altering the one or more external magnetic fields directed towards the assembled bioprinter, and printing, via the assembled bioprinter, a first biostructure onto the internally damaged area of the patient based, at least in part, on altering the one or more external magnetic fields directed towards the assembled bioprinter, wherein the one or more external magnetic fields are sequentially altered to incrementally move the assembled bioprinter along at least one plane.

MULTI-SHIELD SPINAL ACCESS SYSTEM

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

INTRADURAL NEURAL ELECTRODES

Described herein are systems and methods for deploying and recording electrophysiologic signals from electrode arrays located within the dura mater of the brain. The dura matter includes layers of connective tissue, or membrane, that surround the brain and spinal cord. The present disclosure relates to an endovascular electrode system deployed within the blood vessels located between layers of the dura mater, including, for example, the middle meningeal artery and its branches.
