  • Publication number: 20200289794
    Abstract: There is provided an introducer system for percutaneously delivering a first and a second medical device to a patient. The system may comprise an introducer sheath having a longitudinal axis and a lumen formed therein. The system may also comprise a hub coupled to a proximal end of the sheath. The hub may comprise a first arm having a first lumen and a first hemostasis valve for the passage of the first medical device. The hub may also comprise a second arm coupled to the first arm and having a second lumen and a second hemostasis valve for the passage of the second medical device. Further, the hub may comprise a connection port such that the first lumen and the second lumen are in communication with the lumen of the introducer sheath for the passage of at least one of the first and second medical devices through the introducer sheath for delivery to the patient.

  • Publication number: 20200276432
    Abstract: An introducer for insertion of a medical device into a patient's vasculature includes an elongate introducer body, a hub, and a hemostatic valve. The elongate introducer body includes a longitudinal axis, a proximal region, a distal region, and an inner lumen. The hub is coupled to the proximal region of the introducer body. The hemostatic valve is disposed within the hub and forms a liquid-tight seal across the inner lumen. The introducer includes a guide configured to guide an object towards the center of the valve during insertion of the object.

  • Publication number: 20200054861
    Abstract: An introducer sheath for the insertion of a medical device into a blood vessel having an expandable sheath. The sheath has a length, a thickness, and proximal and distal ends. The expandable sheath has a frame extending longitudinally between the proximal and the distal ends, and having an exterior surface and an interior surface that forms an interior lumen along the length of the frame. The frame is configured to achieve an expanded state and a contracted state, the expanded state forming an expanded cross-section in the lumen for passing a medical device therethrough. The frame has a smooth coating about the exterior surface and protrusions extending into the lumen along the interior surface. The introducer sheath can be introduced into a patient in the contracted state, with the distal end of the introducer sheath prevented from moving in the proximal direction by an abutment against a dilator end surface.

  • Publication number: 20190134374
    Abstract: A hemostasis valve body provides strong sealing around a medical device during insertion of the medical device into a blood vessel, low forces for tearing, and stability during insertion of the medical devices as well as during peel away. The valve body comprises a first surface, a second surface opposite the first surface, an edge, helical slits, and a pair of longitudinal cuts. The helical slits are positioned at a center of the valve body and traverse the first surface to the second surface. The helical slits provide a seal around the medical device. Each respective longitudinal cut extends from the first surface partially through the valve body to a depth short of the second surface for at least part of a length of the respective longitudinal cut. The longitudinal cuts facilitate a separation of the valve body into two parts during a peel away action.

  • Publication number: 20190076167
    Abstract: An integrated sheath assembly for inserting f a medical device such as a percutaneous pump into a vessel can include a first sheath having a first lumen defining a first opening between proximal and distal ends of the first sheath for passage of a portion of the pump and a second sheath having a second lumen defining a second opening between proximal and distal ends of the second sheath. The second lumen is expandable to allow passage of the first sheath containing the portion of the pump. The first sheath fills a space between the second sheath and the portion of the percutaneous pump when the first sheath containing the percutaneous pump is inserted into the second lumen. The first sheath has a first hub, and the second sheath has a second hub. In some embodiments, a single sheath and a movable connector can be integrated on the medical device.
