  • Publication number: 20240325011
    Abstract: A system includes an introducer configured to be inserted through the puncture along a guidewire that extends through the puncture into the vessel. The introducer includes an introducer body, a proximal tapered tip, a distal tapered tip that is opposite to the proximal tapered tip along the central axis, and a bore that extends from the proximal tapered tip to the distal tapered tip along the central axis. The system includes an access sheath configured to be inserted over the introducer. The access sheath includes a front end, a rear end opposite to the front end, and a lumen that extends from the front end to the rear end. The proximal tapered tip of the introducer is configured to be inserted into the front end and through the lumen of access sheath, such that a movable interference fit is attained between the access sheath and the introducer.

  • Publication number: 20240293117
    Abstract: A releasable elongated assembly includes a release member having a length and an opening that extends along the length. The releasable elongated assembly includes a first elongated element having a first coupling member disposed in the opening and a second elongated element having a second coupling member disposed in the opening opposite the first coupling member along the length. The first and second elongated elements are interlaced with each other in the opening at a location between the first coupling member and the second coupling member such that the first and second elongated elements are attached to each other. The release member is moveable from a first position where the first and second coupling members are captured in the opening to a second position where the first and second coupling members are released from the opening so as to detach the first and second elongated elements from each other.

  • Publication number: 20240023949
    Abstract: A vascular closure device includes a release component, a delivery component, a sealing device and at least one actuator. The release component is elongate along a longitudinal direction, and defines a distal end and a proximal end. The delivery component extends along the release component such that at least the release component is movable relative to the delivery component. The delivery component includes a delivery tube body and defines a delivery tube channel. The sealing device has a toggle that is at least partially disposed within the release tube, a suture that is attached to the toggle and extends through the delivery tube channel, and a plug that is attached to the suture proximal to the toggle.

  • Publication number: 20230157855
    Abstract: A deployment device for lining a vessel having a housing having a proximal end and a distal end opposite the proximal end, the housing defining a guidewire channel, a tube elongated along a longitudinal axis, the tube having a proximal end and a distal end spaced from the proximal end of the tube along the longitudinal axis, a sheath assembly having a hub removably coupled to the distal end of the housing, and a mesh removably coupled to the tube and positioned along the tube. The tube and the sheath assembly are configured to move along the guidewire and into the vessel through a puncture and release the mesh inside the vessel when at least one of the tube and the mesh is actuated. The device is used as a method of mitigating potential injury or harm to the integrity of the patient’s vessel lining.

  • Publication number: 20220338852
    Abstract: A closure device system for sealing a percutaneous puncture in a vessel wall can comprise a toggle configured to engage an interior surface of the vessel wall, a plug configured to engage an exterior surface of the vessel wall, and a suture that extends through the plug and through the toggle along at least a first direction so as to couple the toggle to the plug. The system can further comprise a tube that extends through the plug and through the toggle along the first direction such that a distal end of the tube is disposed distally to the toggle. The tube can define a guidewire lumen that extends therethrough along the first direction. And the guidewire lumen can be configured to receive a guidewire that protrudes from the vessel wall such that the plug, toggle, and tube are slidable along the guidewire toward the vessel wall.
