  • Patent number: 10433826
    Abstract: The disclosed technology provides a device for sealing an aperture in a tissue of a body lumen. The device comprises a flexible support member having a base having (i) a central portion and (ii) one or more lateral support portions, to engage and/or hold a sealable member of the device against an interior surface of the tissue when the device is in the sealing position. The lateral support portions provide additional support surfaces to engage peripheral portions of the sealable member against the interior surface of the tissue.

  • Patent number: 10206668
    Abstract: The provided technologies provide an implant closure device having a mesh layer formed on a flexible substrate, collectively forming a sealable member, that improves a seal formed over an aperture in a body lumen. The mesh facilitates a faster and more secure adherence of the sealable member to the surrounding edges at the puncture site. Furthermore, the provided technology may promote platelet-capture and encourage localized platelet aggregation at the exposed collagen in the wound edges on the mesh layer. The platelet impregnated mesh layer can facilitate cellular adhesion, enabling the sealable member that is local to the wound opening to act, in essence, as a “biological glue”.

  • Patent number: 9850013
    Abstract: A device for folding an implant having a wing into a an overlapped configuration includes a funnel body comprising: a first portion configured to receive and protect the implant when the wing of the implant is in a flat or relaxed state, a second portion proximal to the first portion and configured to engage and fold opposite first and second side portions of the wing of the implant in a predetermined direction when the implant is retracted proximally from the first portion of the funnel body and into the second portion of the funnel body, and an overlap guide configured to direct the path of a first one of the side portions of the wing such that the first and second side portions of the wing are overlapped in a predetermined manner and to prevent respective edges of the first and second side portions of the wing from butting into each other as the first and second side portions of the wing are guided into the overlapping configuration during proximal retraction of the implant relative to the funnel body.

  • Patent number: 9662099
    Abstract: A device for sealing an aperture in a tissue includes: an implant configured to seal the aperture when positioned adjacent to the aperture; and a delivery shaft configured to engage the implant to allow the implant to be maneuvered into sealing engagement with a distal surface of the tissue, the delivery shaft comprising a retaining sleeve comprising a locking projection engagable with the locking recess of the implant to secure the implant to the delivery shaft, and a release sleeve axially slideable relative to the retaining sleeve between a first axial position in which the release sleeve is configured to maintain locking engagement between the locking recess and the locking projection, and a second axial position in which the release sleeve permits the locking projection to disengage the locking recess.

  • Patent number: 9610070
    Abstract: An interventional medical closure device comprises a first engagement element for engagement with an external surface of a vessel on a first side of an opening through the vessel wall and a second engagement element for engagement with an external surface on a second side of the opening. A closure element extends from the first engagement element, into the vessel, and to the second engagement element to assist in closure of the opening. The device may include a foot element to engage the internal surface of the vessel on both sides of the opening. The foot element may provide a guide with a pathway for the closure element.

  • Patent number: 9060751
    Abstract: A device for closing an opening in a tissue includes a closure body, a fastening element, and a capture strip coupleable to the closure body such that the capture strip is moveable from a first position to a second position relative to the closure body, the capture strip including a receptacle configured to receive the fastening element when the capture strip is in the first position such that movement of the capture strip from the first position to the second position causes the fastening element to urge the closure body toward the tissue.

  • Patent number: 8906050
    Abstract: A medical device for creating and closing an opening through a vessel wall is described. The device includes a guiding engagement element positioned in a vessel wall; an incising member positionable over the engagement element; and a cutting element, with a recessed notch, at a distal end of the incising member. The cutting element forms a flap on a first portion of a vessel wall, the flap having a first portion attached to the wall and second portion having a first diameter cut and a second diameter cut larger than the first diameter cut. The engagement element includes a retaining element engaging a portion of the flap; and an anchoring element engaging an external surface of the vessel, wherein the retaining element and the anchoring element exert a compressive force on the vessel wall for assisting closure of the cut.

  • Patent number: 7753935
    Abstract: An interventional medical closure device is suitable for assisting closure of an opening through a blood vessel wall after completion of an interventional procedure within the internal lumen of the blood vessel. The device comprises a closure element, a grasping element for grasping the closure element, and a delivery element for delivering the closure element into the internal lumen of the blood vessel. The closure element comprises a suture, and an engagement foot at a distal end of the suture. The grasping element is inter-engageable with the closure element to grasp the closure element. The delivery element comprises a main body portion, and a distal nose. The distal nose defines a reception space for carrying the engagement foot of the closure element. The delivery element also comprises an engagement foot which is movable relative to the main body portion between a low-profile delivery configuration and a protruding engagement configuration.
