  • Patent number: 10973639
    Abstract: A system for implanting a repair device onto a native valve of a natural heart to repair the native valve of a patient during a non-open-heart procedure. The system includes a base assembly, a pair of paddles, and a pair of gripping members. The base assembly includes a shaft and a coupler attached to the shaft such that the coupler can be moved along the shaft. The paddles are movable between an open position, a closed position and a bailout position. The paddles and the gripping members are configured to attach to the native valve of the patient. Movement of the coupler along the shaft causes the paddles to move between the open position, the closed position, and the bailout position. When the paddles are in the bailout position, a bailout angle between each paddle of the pair of paddles and the shaft is greater than or equal to 120 degrees.

  • Patent number: 10960188
    Abstract: Treatment methods and devices are provided for percutaneously accessing a patient's thoracic region via a controlled opening in the aorta, so that cardiac procedures, such as a coronary bypass procedure, can be performed in a minimally invasive manner. Advantageously, it may be possible to perform the procedure without placing the patient on cardiopulmonary bypass. The method may include percutaneously delivering at least one catheter into an aorta of a heart, forming a controlled opening in the aorta and pericardium via the at least one catheter to access a thoracic region within the patient's chest, and performing at least one coronary bypass graft procedure through the controlled opening.

  • Patent number: 10939962
    Abstract: A system and method for verifying the accurate insertion positioning of a robotically guided surgical tool or probe, at its cranial target region, such as for Deep Brain Stimulation. A head mounted robot aligns a probe or tool guiding sleeve, together with an aiming rod attached at a predefined position and angle to the guiding sleeve. The aiming rod incorporates apertures through which an X-ray system can view the patient's skull. The aiming rod is attached to the tool guiding sleeve at an angle and position calculated such that the line of sight through the apertures falls exactly on the target region when the tool or probe is inserted to its predetermined depth. If the tip of the tool or probe is seen located at the center of the apertures in the X-ray image, verification is obtained that the insertion procedure has been performed accurately.

  • Patent number: 10842532
    Abstract: Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the surgical device includes a handle, an elongate inner sheath and a circular cutting blade that extends from the distal end of the sheath upon actuating the handle. The circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the surgical device translates along the length of the lead, thereby allowing the lead, as well as any tissue remaining attached to the lead, to enter the device's elongate shaft. The surgical device has a barrel cam cylinder in the handle assembly that imparts rotation of the blade and a separate cam mechanism in the tip of outer sheath assembly that imparts and controls the extension and retraction of the blade.
