  • Patent number: 10687844
    Abstract: An improved catheter atherector for shaving, cutting, and emulsifying accumulated plaque into fine particles, and removing the particles from blood vessel walls without cutting or permanently stretching the walls, and without substantially blocking the blood flow through the vessel during plaque removal operation. The catheter atherector includes an emulsification reduction sphere and extraction wire that rotate and move axially inside the vessel to engage the occlusive material. Emulsified occlusive reduced plaque material and blood only flow in a proximal direction into a catheter lumen. The operation of the device does not substantially disrupt blood pressure within the blood vessel.

  • Patent number: 10660670
    Abstract: A cervical dilator and methods of using the cervical dilator include guiding a shaft and a balloon of the cervical dilator through a cervix to seat the balloon in an uninflated state within a cervix. Seating the balloon includes locating proximal and distal ends of the balloon near proximal and distal ends of the cervix such that the balloon fills a canal of the cervix. After seating the balloon within the canal of the cervix, the method includes introducing a predetermined amount of fluid into the balloon cavity to fill the balloon to an inflated state. While the balloon is in the inflated state, the method includes waiting a predetermined time period to allow cervical dilation. After waiting the predetermined time period, the method includes applying light tension to the exterior surface of the shaft to remove the shaft and the balloon in the inflated state from the cervix.

  • Patent number: 10617405
    Abstract: Embodiments of the invention describe methods of implanting and setting an adjustable suture structure capable of maximizing and controlling the available range of motion in a defective joint. The adjustable suture structure can augment a joint repair following surgery or be used as a standalone construct. One embodiment involves completion of a standard ligament repair, followed by the implant of anchors to secure sutures between bone locations proximal to the native origin of the repaired ligaments. Each of the sutures is implanted with at least some slack. Once the sutures are secured, the first suture is alternatively tensioned and moved through a range of motion, followed by the same process in a second suture. The steps are performed iteratively until the range of motion is controlled or limited sufficiently to protect the repaired ligaments.

  • Patent number: 10603024
    Abstract: In general, devices, systems, and methods for relocating tissue during surgeries are provided. In one embodiment, a surgical apparatus is provided that includes a needle, a hook movably disposed in the needle, an actuator, and a slidable member. The needle can be percutaneously advanced through skin of a patient. The actuator can move the hook between two orientations, one being disposed entirely within the needle and another extending from the needle. The slidable member can slide along the needle and abut an exterior surface of the skin of the patient through which the needle is advanced. In use, the hook can engage tissue within the body of the patient when the hook extends from the needle. The surgical apparatus can then move the engaged tissue within the body of the patient, and the engaged tissue can be locked in position relative to the skin.

  • Patent number: 10555813
    Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those heart valve implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. Anchors secure the implant to tissue and collars are used to decrease the angle between the struts and contract the frame. The implant thus expands from a first size inside of a delivery catheter, to a second and larger deployed size inside the heart to engage and anchor with the tissue, and then to a third and contracted size to re-size the annulus and/or provide a secure fit for a replacement heart valve. Various delivery systems including imaging capabilities for precise delivery, positioning and anchoring of the various implants are further described.
