    摘要: A method for accessing a target site in the body by transferring a guidewire from an initial insertion site on the body to a different insertion site on the body is provided. In one aspect, a method for transferring a medical device or component, such as a sensor lead, from an initial insertion site to another insertion site is also provided. A guidewire of sufficient length, pliancy and deformability to perform a transfer from one insertion site to another insertion site is provided. In one aspect, the guidewire comprises a removable core mandrel to increase rigidity, facilitate insertion and/or improve steerability. A kit or system, comprising introducers, guidewires and catheters for performing a guidewire or device transfer is also provided.

    摘要: Systems and methods for penetrating a tissue membrane to gain access to a target site are disclosed. In some examples, systems and methods for accessing the left atrium from the right atrium of a patient's heart are carried out by puncturing the intra-atrial septal wall. One embodiment provides a system for transseptal cardiac access that includes a stabilizer sheath having a side port, a shaped guiding catheter configured to exit the side port and a tissue penetration member disposed within and extendable from the distal end of the guide catheter. The tissue penetration member may be configured to penetrate tissue upon rotation and may be coupled to a distal portion of a torqueable shaft. In some embodiments, the stabilizer sheath and shaped guiding catheter may be moved relative to the patient's body structure and relative to each other so that a desired approach angle may be obtained for the tissue penetration member with respect to the target tissue.

    摘要: A method of displaying details of a coronary artery lesion in a cineangiogram, by adjusting each frame of the cineangiogram so that the lesion is continually displayed at a fixed location on a display. The remaining cardiac anatomy appears to move, in background, past a stationary arterial segment, thus making the displayed arterial segment easier to identify and to examine by medical personnel. Cineangiographic image frames are digitized and processed by a processor and the image frames are digitally shifted to place the arterial segment in substantially the same viewing location in each frame. Sequential image frames may be presented to the viewer as a stereoscopic pair, to produce pseudostereopsis. The arterial segment appears to the viewer in foreground, as if it was floating in front of the remaining cardiac anatomy. Image frames may be further processed to aid examination by medical personnel. The processor may make quantitative measurements of the cineangiogram and may display results of those measurements to aid review of the cineangiogram. Frames may be averaged to reduce quantum noise and to blur any structure noise; frames may be compared with prior cineangiograms to increase clarity or contrast. Coordinate adjustments for a cineangiogram may help guide therapeutic procedures, or may help enhance other imaging procedures such as fluoroscopy.

    摘要: An expandable medical device having a plurality of elongated struts, the plurality of elongated struts being joined together by ductile hinges to form a substantially cylindrical device which is expandable from a cylinder having a first diameter to a cylinder having a second diameter. The plurality of struts and ductile hinges are arranged to improve the spatial distribution of the struts which is particularly important when delivering beneficial agents with the struts. The improved strut arrangement expands to a substantially parallelogram shape for improved beneficial agent distribution to the surrounding tissue. A beneficial agent may be loaded into openings within the struts or coated onto the struts for delivery to the tissue.

    摘要: A hemostasis valve is disclosed herein. The hemostasis valve may include an inner bushing, a rotation sleeve, an elastomeric sleeve, and a biasing element. The rotation sleeve may extend about the inner bushing and be rotationally displaceable relative to the inner bushing. The elastomeric sleeve may include a first end operably coupled to the inner bushing, a second end operably coupled to the rotation sleeve, and an iris valve portion. Rotation of the rotation sleeve relative to the inner bushing may cause the iris valve to transition from an open state to a closed state. The biasing element may act between the rotation sleeve and inner bushing to bias the iris valve towards at least one of a closed state or an open state.
