    摘要: A catheter deliverable stent/graft especially designed to be used in a minimally invasive surgical procedure for treating a variety of vascular conditions such as aneurysms, stenotic lesions and saphenous vein grafts, comprises an innermost tubular structure and at least one further tubular member in coaxial arrangement. In one embodiment, the innermost tubular structure is of a length (L1) and is formed by braiding a relatively few strands of highly elastic metallic alloy. The pick and pitch of the braid are such as to provide relative large fenestrations in the tubular wall that permit blood flow through the wall and provide the primary radial support structure. A portion of the innermost tubular structure of a length L1 is surrounded by a further braided tubular structure having relatively many strands that substantially inhibit blood flow through the fenestrations of the innermost tubular structure. The composite structure can be stretched to reduce the outer diameter of the stent/graft, allowing it to be drawn into a lumen of a delivery catheter. The catheter can then be advanced through the vascular system to the site of treatment and then released, allowing it to self-expand against the vessel wall. Various optional embodiments are disclosed that allow one skilled in the art to tailor the design to the specific application.

    摘要: The present invention provides a delivery mechanism for percutaneously routing a stent or graft through the vascular system and procedures for addressing an aneurysm or an otherwise damaged vessel. The delivery system includes an outer tubular guide catheter 20, an inner tubular delivery (pusher) catheter 14 coaxially disposed and slidable relative to the outer guide catheter and an elongated flexible wire or cable 26 that is coaxially insertable through the lumen of the inner tubular catheter and that has a frusto-conical bead affixed at the distal end thereof which is sized to at least partially fit within the lumen of the inner pusher catheter when a proximally directed tension force is applied between the elongated flexible wire or cable 26 with respect to the pusher catheter 14. By inserting a compressed coil spring between a proximal end portion of the pusher catheter 14 and the proximal end portion of the cable 26, the requisite clamping force is maintained to secure the stent or graft to the distal end of the pusher catheter until the compression spring force is removed. With the stent or graft clamped to the distal end of the inner pusher catheter, it can be drawn within the lumen of the outer guide catheter for delivery therewith to the target site.

    摘要: A device and method for delivering an object within a patient, wherein the object is delivered in a preferred orientation relative to the delivery site of the patient. The delivery device has an alignment member that allows the object to be delivered intravascularly to the delivery site of the patient, wherein the object is delivered in a pre-determined orientation. The object may, for example, be non-symmetric or include a configuration that requires delivery to the site in only one suitable orientation relative to the delivery site. Such objects may be used, for example, to treat certain defects or injuries in vessels or organs within a patient's body.

    摘要: A sizing catheter and method of measuring a preselected internal opening within a patient to provide a rapid and precise determination of first and second stretched diameters of the preselected internal opening. The sizing catheter includes a dilation balloon constructed of a thin expandable plastic, which is inflatable and is utilized to determine a size of the preselected opening. The dilation balloon is inflated to an inflation threshold wherein the dilation balloon deforms about the preselected opening and the size of the dilation balloon adjacent the preselected opening approximates the first stretched diameter of the preselected opening. The sizing catheter and method may be utilized to determine an appropriate sized device to be positioned within the preselected opening.

    摘要: A medical catheter introducer and hemostasis valve assembly consists of a sheath having an elongated tube defining a conduit, a housing disposed at the proximal end of the sheath and further defining a conduit and an orifice, and a flexible elongated dilator sized for insertion through the hub and sheath conduit. The dilator has a tapered distal tip end and defines an axial conduit and an annular ridge having distally- and proximally-directed inclined surfaces. The sheath, when assembled with the dilator, has its distal end immediately adjacent the proximally-directed inclined surface of the ridge. A hemostasis valve for sealing the conduit is disposed in alignment with the conduit, and defines an aperture for passage of dilator and ridge therethrough in sealing engagement, into the conduit, and seals when the dilator is removed. The valve has a housing defining an orifice of a first diameter, and a valve element of a second diameter, greater than the first diameter. The valve is disposed within the orifice and is subject to externally-applied, radially directed forces that cause the valve to assume a dome-shape formation, with a convex surface disposed against the pressure of fluids within the body. As the introducer assembly is introduced into a body over a guidewire extending via a puncture opening into a vessel, the dilator and sheath flex to follow the guidewire, and the tapered end of the dilator and the distally-directed inclined surface of the ridge act to dilate the flesh about the opening to facilitate passage of the sheath. The introducer and valve may be used alone, or respectively with valves or introducers of other design. A base for attachment of the introducer to the patient is also described.

    摘要: A device for performing percutaneous puncture treatment of a patient includes an elongate radiolucent plastic handle with a central portion and two opposite elongated end portions. A hollow radiopaque needle has a hub at its proximal end which is releasably mounted in the central portion of the handle so that the needle is perpendicular to an axis through the end portions. The distal end of the needle has a puncturing tip. An internal fluid passage in the needle is open to the tip and the hub so that fluid may be drained from a patient's body through the passage when the needle is inserted in the patient's body. The needle and central portion of the handle are aligned under a field of view of a fluoroscope. The handle is held by the grips which are outside of the field of view of the fluoroscope. While the doctor continuously monitors progress of the needle on the fluoroscope, the puncturing tip is inserted through the skin and moved to an internal location for aspiration of fluid. Medical personnel are safely outside of the field of view of the fluoroscope during the entire process.
