  • Publication number: 20240398565
    Abstract: Systems and methods treat a heart valve using a magnetically adjustable annuloplasty ring attached to or near a cardiac valve annulus. A changing magnetic field may be used to selectively increase or decrease a circumference of, or otherwise modify the shape of, the implanted annuloplasty ring. The adjustable annuloplasty ring includes a tubular body member, one or more adjustable members, and an internal magnet within the tubular body member. The tubular body member and the one or more adjustable members form a ring shape. The internal magnet is configured to rotate in response to a rotating external magnetic field. The internal magnet is coupled to the one or more adjustable members to change a dimension of the ring shape as the internal magnet rotates. A system for treating a heart valve may include an external adjustment device having one or more external magnets to generate the rotating external magnetic field.

  • Patent number: 11931069
    Abstract: An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a mounting ring which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the mounting ring and the clip.

  • Publication number: 20240074640
    Abstract: A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).

  • Publication number: 20230363691
    Abstract: The devices and methods described below provide for more convenient stereo-electro-encephalography, which may allow the patient to move freely during the days-long monitoring period. The system includes a number of depth SEEG electrodes. In one version of the system, each SEEG electrodes are wirelessly connected to an EEG console, through a subcutaneous electrode which is connected to the SEEG electrode through a conductor. The subcutaneous electrode is in turn wirelessly connected to a supra-cutaneous appliance operable to obtain SEEG signals, generated by the SEEG electrode, through the subcutaneous electrode. The method of use entails implantation of the depth SEEG electrodes deep in the brain, implantation of the subcutaneous electrodes under the scalp. The patient need not be physically connected to a console or control system, and may be ambulatory for the SEEG protocol period.
