    Abstract: The bending flexibility profile of a stent closely matches the flexibilities of the stent delivery system on either side of the stent. In one embodiment, a stent has a longitudinal axis and at least one link attaching each ring to an adjacent ring. The links closest to the stent end rings have the greatest bending flexibility and the links closest to the center of the stent have the least bending flexibility.

    Abstract: An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen for treating an area of vulnerable plaque. The invention provides for a an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. A central section is positioned between distal and proximal sections and is aligned with the area of vulnerable plaque to enhance growth of endothelial cells over the fibrous cap of the vulnerable plaque to reinforce the area and reduce the likelihood of rupture.

    Abstract: The invention is directed to apparatus, methods and systems including a sheath for use with intracorporeal optical imaging instruments such as imaging guidewires, catheters, or endoscopes. The invention provides a sheath suitable for guiding an enclosed instrument, that is effective to guide the placement within a patient's body and replacement to a distal position after retraction of the imaging instrument, as during an imaging scan. The sheaths may include at least a portion that is translucent to a desired wavelength of radiation. The translucent portion may have an index of refraction similar to the index of refraction of a bodily fluid such as blood plasma, or an artificial fluid suitable for introduction into a body lumen.

    Abstract: A catheter having a polymeric reinforcing member at a junction between shaft sections such as a rapid exchange catheter junction. The polymeric reinforcing member is around or within the tubular member defining the inflation lumen or the tubular member defining the guidewire lumen at the rapid exchange junction to prevent or inhibit damage to the tubular members defining the inflation lumen and/or guidewire lumen during assembly or use of a balloon catheter. In one embodiment, the polymeric reinforcing member is formed of a first polymeric material having a glass transition temperature greater than a glass transition temperature of a second polymeric material forming the distal portion of the proximal tubular member or the proximal portion of the inner tubular member. The first polymeric material forming the polymeric reinforcing member is preferably a high temperature, high modulus material, such as polyimide, and most preferably a thermoset polyimide.
