    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.

    摘要： A depth and puncture control system for a blood vessel hemostasis system includes a blood vessel puncture control tip which, when positioned in the lumen of a blood vessel, can inhibit the flow of blood out of the puncture site. When used together with a pledget delivery cannula and a pledget pusher, the control tip and the delivery catheter can both inhibit blood loss out the puncture site and inhibit the introduction of pledget material and tissue fragments into the blood vessel. The system also includes a handle which releasably connects together the control tip, pusher, and delivery cannula to permit limited longitudinal motion between the control tip and the delivery cannula, and between the pusher and the delivery cannula.

    摘要： A surgical instrument (10) is adapted to contact tissue of a patient, and to provide traction with the tissue in order to inhibit migration of the instrument relative to the tissue. The instrument may include a pair of opposing jaws (16, 18) with at least one of the jaws (16, 18) comprising a substrate having a particular surface facing the tissue, and a plurality of discrete elements (26, 28) disposed on the particular surface for increasing the traction of the instrument relative to the tissue. These discrete elements (26, 28) may include a multiplicity of granules, bristles, or projections, and may be formed of materials having various properties such as hydrophilic characteristics. The discrete elements in the form of bristles can be oriented too so that the column strength of each bristle provides increased traction in a predetermined direction.

    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 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.
