  • Patent number: 10687938
    Abstract: Docking devices can be configured to be positioned at a native valve of a human heart to provide structural support for docking a prosthetic valve. The docking devices generally have coiled structures that define an inner space in which the prosthetic valve can be held. Some docking devices can be adjusted from a first wider configuration which facilitates easier advancement of the docking device around the valve anatomy, to a second narrower configuration after the docking device has been delivered to more securely hold the prosthetic valve. The docking device may also be better held in position at the native valve after adjustment to the narrower configuration. Some docking devices include a stabilization segment or double coil configuration, where a main coil region is configured to securely hold a prosthetic valve, while a stabilization coil region is configured to more stably hold the docking device at the native valve.

  • Patent number: 10661060
    Abstract: A method is disclosed for selective inflation of an inflatable body, such as a balloon, received through an oral cavity and into the esophagus of a patient. The inflatable body is operably coupled to a pressurized fluid source. The inflatable body has a relatively flexible portion and a relatively inflexible portion. When pressurized fluid is delivered to the body to inflate the body, the flexible portion expands more than the inflexible portion, resulting in asymmetrical expansion and movement of the esophagus away from the ablation site to avoid accidental injury while performing a procedure on the patient's left atrium. This movement may be opposite from or directly away from the heart or, alternatively, may be sideways relative to the heart to a location in which the esophagus is interposed between the ablation site and the phrenic nerve.

  • Patent number: 10639023
    Abstract: A method and apparatus for securing soft tissue to bone can include loading a suture through an eyelet of a suture anchor. The suture anchor can have a longitudinal axis and a distal tip. An anchor inserter assembly can be positioned in contact with the suture anchor. The anchor inserter assembly can include a sleeve portion and an impacting portion. The suture can be engaged with a suture engaging member on the suture inserter assembly at a location adjacent to the eyelet. The sleeve portion can be translated relative to the impacting portion from an alignment position to an insertion position thereby moving the suture a first distance offset from the eyelet in a direction away from the distal tip. The anchor insert assembly can be advanced to a driven position thereby advancing the suture anchor into the bone. The suture engaging member can be released from the suture.
