  • Publication number: 20020108621
    Abstract: Methods and apparatus for delivering and installing a new length of tubing between two sections of a patient's existing body organ tubing and at least partly outside of that existing structure. For example, the new length of tubing may be for the purpose of providing the patient with a coronary bypass. The new tubing may be an artificial graft, a natural graft (harvested elsewhere from the patient), or both. The new tubing is installed at the operative site primarily by providing at least one graft location with instrumentation inserted through the patient's existing tubular body organ structure. Assistance in installing the new tubing may be provided by minimally invasive surgical access openings in the patient's chest. The tubing may be delivered through the patient's existing tubular body structure or, alternatively, through the surgical access openings.

  • Publication number: 20020091398
    Abstract: Methods and apparatus for making an anastomotic connection between a first conduit and a second conduit. A connector structure having a first end portion and a second end portion is positioned about a balloon catheter, which when pressurized, expands to a significant extent at the distal end thereof. The balloon enlarges the connector structure when positioned at the distal end portion of the balloon to create the anastomosis, and at the same time reduces the axial length of the connector, thereby compressing the first conduit to the second conduit, creating a hemodynamic seal and a firm attachment of the two conduits. After enlargement, the connector structure remains in place and adds structure to the anastomosis. During introduction, the second end portion of the connector is covered by a nosecone assembly to prevent trauma to the second conduit while the apparatus is being introduced.

  • Patent number: 6416527
    Abstract: A catheter-based system for accessing specific body cavities percutaneously and minimizing patient trauma is provided. In the preferred embodiment, in order to create an aperture at an access site in a patient's existing tubular body organ structure, a delivery sheath is passed axially along the interior of a portion of the existing tubular body organ structure to place a distal end of the delivery sheath near the access site. A centering wire is passed axially along the interior of the delivery sheath, piercing through from inside to outside of the patient's existing tubular body organ structure at the access site by causing an end portion of the centering wire to emerge from the distal end of the delivery sheath. A cutting catheter is passed substantially coaxially over the centering wire and axially along the interior of the delivery sheath.

  • Publication number: 20020082614
    Abstract: Instrumentation for facilitating cutting an opening in a side wall of a body conduit in a patient. A tubular structure defines a lumen and has a sharpened distal end portion configured to cut a section of the body conduit to create the opening. A tissue holding structure is provided which is axially movable within the lumen of the tubular structure. The tissue holding structure includes a piercing portion to permit passage of the tissue holding structure through the body conduit from an entrance side to an exit side thereof. The tissue holding structure also includes a retention member to secure the section of the body conduit to the tissue holding structure during movement of the tissue holding structure to approximate the entrance side of the body conduit with the sharpened distal portion of the tubular structure to enable the sharpened distal structure to cut the body conduit. A connector is also provided for attaching a new length of tubing to the body conduit at the opening made by the cutting.

  • Patent number: 6371982
    Abstract: A distensible artificial tubular graft structure is provided that has a compliance gradient. The graft may be used to repair a patient's body organ tubing. For example, the graft may be used to replace or supplement portions of a patient's vascular system. The ends of the graft structure may have compliances that are matched to the compliances of the body organ tubing to which they are attached. Distensible compliance-matched connector structures may be used to attach the graft to the body organ tubing.

  • Publication number: 20020032458
    Abstract: Connectors are provided for making connections between tubular conduits in medical procedures such as those involving treatment of a patient's circulatory system. The connectors are variously configured for making end-to-side or end-to-end connections of tubular conduits. One of the tubular conduits may be a graft conduit, which can be artificial conduit, natural conduit, or a combination of both. The connectors for making end-to-side connections can be generally T-shaped or L-shaped. Various portions of the connectors can attach to the inside or outside of the associated conduit, depending on the connector configuration that is selected.

  • Publication number: 20020022853
    Abstract: A connector for use in providing an anastomotic connection between two tubular body fluid conduits in a patient. The connector is preferably a single, integral, plastically deformable structure that can be cut from a tube. The connector has axial spaced portions that include members that are radially outwardly deflectable from other portions of the connector. The connector is annularly enlargeable so that it can be initially delivered and installed in the patient in a relatively small annular size and then annularly enlarged to provide the completed anastomosis. The radially outwardly deflected members of the first and second portions respectively engage the two body fluid conduits connected at the anastomosis and hold those two conduits together in fluid-tight engagement. Apparatus for use in delivering and deploying a connector is also disclosed.

  • Publication number: 20010010007
    Abstract: A body tissue graft for use in a patient includes a frame structure made of a first elastic material, a covering of a second elastic material on the frame structure, the covering substantially filling openings in the frame structure, and a connector connected to the frame structure. Projections are secured to the connector structure. The projections facilitate attachment of the tubular graft in a patient by securing the graft to the body tissue with which the graft is employed. The connector selectively circumferentially expands and the projections selectively circumferentially expand. This may be done using an inflatable balloon to circumferentially expand the projections. A restraining member may be provided to restrain the projections in a cone shape so that an end of the graft may be used to open an aperture through a side wall of existing body organ tubing and a portion of the projections may enter the aperture.

  • Patent number: 6261315
    Abstract: To facilitate subsequent location of a point along a patient's tubular body structure (e.g., a circulatory system vessel), a marker structure is inserted into and along the lumen of that tubular body structure. At the desired point along the lumen, a distal portion of the marker structure is made to pass out through a side wall of the tubular body structure so that it projects from that side wall and visibly and/or radiologically marks the desired point along the tubular body structure. The marker structure may also be used as an anchor for other instrumentation brought up to the outside of the tubular body structure (e.g., for use in further treatment of the tubular body structure).
