  • Patent number: 6964658
    Abstract: A system for facilitating hemostasis of a puncture site in a blood vessel delivers 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 staging chamber, a delivery cannula, and a pusher. The staging chamber is used for hydrating a pledget of absorbable sponge, compressing the pledget, and delivering the pledget to the delivery cannula. The staging chamber may include a valve for facilitating hydration and staging of the pledget. The delivery cannula and pusher are used to accurately place the sponge pledget outside the blood vessel. An easy loader connector may be used to facilitate loading the dry pledget into the staging chamber.

  • Patent number: 6872778
    Abstract: Disclosed is a method for forming a gasket seal or transition fitting affixed to one of two parts to be joined in a gasketed joint by use of the gasket. The method includes the step of providing a mold having a walled mold cavity of the shape desired for the gasket, at least one wall of the mold cavity being a junction surface of the one part and the remaining walls of the mold cavity being formed in a mold piece. The mold is closed by placing the mold piece over the junction surface of the one part to establish the mold cavity as a closed generally toroidal volume. Then a molten gasket-forming thermoplastic material is injected into the mold cavity to form the gasket, the thermoplastic material including a bonding agent for establishing an adhesive bond between the junction surface and the gasket. The thermoplastic material is cooled to solidify the gasket and affix it to the junction surface and the mold piece is removed away from the junction surface.

  • Patent number: 6863680
    Abstract: 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.

  • Patent number: 6846320
    Abstract: 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.

  • Publication number: 20040019330
    Abstract: The present invention discloses a sheath based puncture locator and depth indicator. The present invention provides for locating a blood vessel puncture site and determining the depth of the puncture of the blood vessel extravascularly using the introducer sheath that is already in place within the tissue tract. The present invention also provide for positioning the introducer sheath extravascularly or outside the blood vessel, controlling the blood vessel puncture site, and delivering a hemostasis promoting material to a blood vessel puncture site.

  • Patent number: 6610026
    Abstract: A method of hydrating a sponge material for delivery to a body. The method includes the steps of placing a dry piece of sponge in a container at a first pressure. A hydrating fluid is then introduced into the container to hydrate the sponge. The pressure within the container is changed between the first pressure and a second pressure. At least a portion of the hydrating fluid is removed from the sponge, and the sponge is delivered to a bodily site.
