    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 controlled 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.

    摘要： A system for facilitating hemostasis of a puncture site in a blood vessel injects an absorbable sponge pledget in a hydrated state to a position at an exterior of the blood vessel puncture to facilitate hemostasis. The system includes a tract dilator for locating the puncture, an introducer, and a pusher. The introducer includes a staging chamber for receiving the absorbent sponge pledget and a delivery chamber having a diameter smaller than a diameter of the staging chamber into which a hydrated pledget passes. The pledget is hydrated and compressed within the introducer and then ejected with the pusher to the delivery site to facilitate hemostasis of the blood vessel puncture. The system delivers the absorbable sponge pledget over a guidewire to ensure the proper positioning of the pledget over the puncture. The implanted absorbable sponge once delivered expands rapidly to fill the target site and is absorbed by the body over time.

    摘要： A device for determining the depth of an incision from the epidermal layer to a puncture in a blood vessel in which the device includes an elongated member which has a lumen extending from a distal end to a proximal end. The distal end of the elongated member is configured to locate the blood vessel. After the device locates the blood vessel, a depth indicator is positioned to mark the depth of the blood vessel. In one embodiment, the elongated member includes a tapering interior surface which can receive a portion of the blood vessel. An extending control member may extend from the device at the distal end wherein the extending control member enters the blood vessel before the device locates the vessel. Fluid from the blood vessel enters the extending member through a vent hole and exits through an opening at the proximal end of the device, thereby providing a user with visual feedback that the device is moving in the desired direction toward the blood vessel.

    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 biopsy cannula and a delivery catheter are configured to deliver one or more absorbable sponge pledgets to a biopsy site after removal of one or more tissue samples from the site. The delivery catheter allows a large amount of hydrated sponge material to be delivery to the biopsy site to facilitate hemostasis. One example of the delivery catheter includes a closed distal end, a side port, a tapered section, and an enlarged proximal portion for receiving the pledget. The side port of the delivery catheter is arranged to delivery the pledget through the side port of the biopsy cannula. In order to fill a relatively large biopsy site where multiple tissue samples have been taken in a radial pattern, the biopsy cannula is rotated and additional pledgets are delivered to the biopsy site at different radial locations. The absorbable sponge pledget may also be used as a marker for location of the biopsy site at a later time.
