  • Patent number: 11553905
    Abstract: A device, method, and use of a device for temporary management of a wound, such as a wound in a heart. The device has a shaft, a blood flow blocking membrane at the first end of the shaft for blocking blood flow through the wound, and an abutment member that is mounted to the shaft and is axially movable along the shaft towards and away from the blood flow blocking membrane for abutting the wound and holding the blood flow blocking membrane adjacent the wound. The blood flow blocking membrane is resiliently flexible and movable between at least a first collapsed state for inserting the blood flow blocking membrane through the wound, and a deployed state for blocking blood flow through the wound.

  • Patent number: 11389609
    Abstract: A tracheotomy device includes a head with a head proximal end and a head distal end. The head has a dilating member, and the dilating member has a first dilating member side piece and a second dilating member side piece. The dilating member is moveable between a closed configuration in which the first and second dilating member side pieces are adjacent, and an open configuration in which the first and second dilating member side pieces are spaced apart. The dilating member tapers in cross-sectional area going in a direction from the head proximal end to the head distal end. A sharp tip is at the head distal end. A gripping member is connected to the head proximal end, and is actuatable to move the dilating member between the closed configuration and the open configuration.

  • Patent number: 11058415
    Abstract: A suture guide includes a first part having a first base piece and a plurality of first needle portions joined to the first base piece. Each first needle portion has a respective first needle portion sidewall. The suture guide further includes a second part having a second base piece and a plurality of second needle portions joined to the second base piece. Each second needle portion has a respective second needle portion sidewall. The first part and second part are moveable between a separated configuration and a joined configuration. In the separated configuration, the first needle portions are spaced away from the second needle portions. In the joined configuration, each one of the first needle portions is positioned adjacent and cooperates with a respective one of the second needle portions to form a needle.

  • Patent number: 10524793
    Abstract: A device for management of an open abdomen includes a belt having first and second end portions. The belt is positionable to extend partially around a patient's torso in a taut configuration with the end portions positioned on opposed sides of an incision in the patient's abdomen. A first connector is at the first end portion and a second connector is at the second end portion. The connectors are positionable adjacent each other on the opposed sides of the incision. At least one cinching device is connected to and extends between the connectors. The cinching device is positionable to extend over the incision when the connectors are positioned adjacent each other on opposed sides of the incision. The cinching device is adjustable to cinch the end portions towards each other to hold the incision in an at least partially closed position.
