    摘要： A catheter includes an introducer and a flow isolator adapted for disposition in a primary conduit to facilitate flow in the primary conduit while inhibiting flow and intersecting secondary conduits. The flow isolator may include a tubular mesh and surrounding balloon structure. Alternatively, a sleeve can be provided with a primary opening and a secondary opening which are sized to inflate the sleeve with the body fluid. Structures for deploying the sleeve between a low-profile state and high-profile state may include expandable fingers, or pneumatic chambers inflatable from an external source. In operation the sleeve can be forced by the body fluid against the intersection with the secondary conduits to achieve isolation. Alternatively, the pneumatic chambers can be inflated to form seals with the primary conduit. A blood filter or snare is contemplated to filter any blood clots which may develop around the flow isolator.

    摘要： An access device having a single sheath is inserted into a body passage puncture, with an expandable member of the access device held to a minimum diameter. The expandable member is held to the minimum diameter using structure that does not increase the diameter of the access device, rather than a large-diameter external sheath. The structure for holding the expandable member to a minimum diameter can subsequently be removed from the lumen of the access device., once the expandable member has been expanded.

    摘要： A method of facilitating hemostasis of a blood vessel puncture. The method includes the steps of inserting a tubular device into a puncture in a blood vessel to establish access to the blood vessel, providing a vessel closure system around the tubular device, introducing a hemostatic material into a space between the tubular device and vessel closure system, and delivering the hemostatic material adjacent to the puncture to facilitate hemostasis of the puncture.

    摘要： The present invention provides for an apparatus to locate a blood vessel puncture having a bleed back entrance port near a first end, a bleed back exit port near a second end; and a lumen extending between the bleed back entrance port and the bleed back exit port, wherein said bleed back entrance port has a diameter substantially equal to or greater than the lumen diameter. The present invention further provides for a method for locating a blood vessel puncture by inserting a locator into a blood vessel lumen, the locator having a bleed back entrance port at a first end, a bleed back exit port at a second end, and a finger adjacent the bleed back entrance port, observing a blood flow out of the bleed back exit port, and withdrawing the locator out of the blood vessel lumen until the finger contacts the blood vessel wall.

    摘要： A system for delivering hemostasis promoting material of the present invention allows the hemostasis promoting material to be delivered to a blood vessel puncture site by fluid pressure. The system allows the hemostasis promoting material to be delivered through an introducer sheath which is already in place within a tissue tract. This system includes a control tip which is insertable through the introducer sheath to locate and occlude the blood vessel puncture site and a hydration chamber for receiving and delivering the hemostasis promoting material to the blood vessel puncture site. The system accurately locates the blood vessel wall at a puncture site and for properly placing a hemostasis plug over the puncture site.
