  • Publication number: 20200138421
    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: 7976503
    Abstract: A haemostasis device (200) comprises a low pressure seal (206) and a high pressure seal (208). A tubular bayonet (201) is movable from a retracted configuration to an inserted configuration to move the low pressure seal (206) between a closed configuration and an open configuration. With the low pressure seal (206) in the open configuration, a guidewire (222) may be inserted through the low pressure seal (206), and with the low pressure seal (206) in the closed configuration, the guidewire (222) may be passed through the low pressure seal (206) while maintaining sealing around the guidewire (222). A collet (209) is movable in a radial direction to move the high pressure seal (208) between an open configuration and a sealing configuration. With the high pressure seal (208) in the sealing configuration, the guidewire (222) is locked in position.

  • 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.
