  • SYSTEMS, METHODS, AND DEVICES FOR CLOSING HOLES IN BODY LUMENS
    Publication number: 20240057995
    Abstract: A device for closing an opening in a body lumen, the device having a first elongate member with a first lumen, a second elongate member distal the first elongate member, and a needle assembly slidably cooperating with the first elongate member to position a plurality of sutures within the lumen of the first elongate member. The needle assembly includes a needle base and a plurality of needle portions extending from the needle base. Slidable movement of the needle assembly in relation to the first elongate member locates the plurality of sutures selectively mounted to the needle assembly within the first lumen.
    Type: Application

  • Systems, methods, and devices for closing holes in body lumens
    Patent number: 10980531
    Abstract: A closure device for closing an opening in tissue is provided. The closure device includes an elongate member through which needles may be deployed. The closure device also includes a foot portion having one or more feet slidably mounted relative thereto. The feet are movable between a deployed position and a delivery position. The feet include cuffs removably mounted therein, with sutures connected between the cuffs. When the feet are in the deployed position and the needles are advanced, the needles securely engage the cuffs and draw the cuffs and suture through the lumen wall so that the opening in the lumen wall can be closed with the sutures.
