    摘要: The present invention is directed to a gauging system and method for using the same for determining the size of a lesion within a patient's body prior to stenting the lesion. In one embodiment the gauging system includes a catheter having an elongated shaft with proximal and distal ends, and an outer sheath formed of a compliant material and disposed about at least a portion of the catheter elongated shaft and being slidable over the same. In another embodiment, the gauging system further includes a radially expandable member formed of the same or different compliant material mounted on a distal section of the shaft and has an interior chamber in fluid communication with an inflation lumen extending within at least a portion of a distal shaft section to a location spaced proximally from the shaft distal end.

    摘要: A method of treating vulnerable plaque comprising intentionally damaging or rupturing the vulnerable plaque using a wingless balloon which is inflated from a wingless unexpanded diameter to a limited expanded diameter. This process produces significant increase in ECM synthesis at the site of the damage or rupture. As a result, the method strengthens the vulnerable plaque while minimizing or avoiding damage to the surrounding wall of the body lumen or damaging a stable plaque mistakenly believed to be a vulnerable plaque. The method of the invention is particularly useful in treating a fibroatheroma type of vulnerable plaque. In one embodiment, the balloon is self-limiting such that it expands compliantly at initial inflation pressures, and above nominal pressure it expands noncompliantly. In an alternative embodiment, the balloon is inflated using a diameter-limiting device, such as a device which limits the inflation pressure or the volume of inflation fluid in the balloon.

    摘要: A composite tubular element for intravascular catheters, such as fixed-wire dilatation catheters and guiding and angiographic catheters, which is formed by braiding strands formed from an intimate mixture of polymeric matrix materials, such as fibers and powders, having a relatively low melting point and high strength reinforcing fibers having a relatively high melting point into a tubular element, heating the braided tubular element to melt the low melting point matrix materials and flow around the reinforcing fibers to form a matrix. A thermoplastic jacket or coating may then be extruded or otherwise applied to the exterior of the braided tubular element.

    摘要: In one embodiment, there is disclosed a device adapted to be used for percutaneous minimally invasive heart surgery including a catheter having a proximal end and a distal end adapted to be fed through a blood vessel, a pump associated with the distal end of the catheter, and a tool associated with the distal end of the catheter. The tool is adapted to be used for percutaneous minimally invasive heart surgery. Examples of the tools include a tool for excising natural tissue, a tool for excising a natural valve, and anthretomy device, a prosthetic valve delivery system, a balloon catheter, a knife, a stapler, and a screwdriver. The pump is used for maintaining blood flow around the site of the heart surgery while the surgery is taking place without the use of cardiopulmonary bypass.
