    摘要: A stent delivery catheter system for accurately positioning a stent in a bifurcated vessel is disclosed. The system includes a catheter having a terminal portion and distal tip that is placed in a main branch of the vessel proximate the bifurcation. A fixed guidewire is attached to distal tip. A port is defined in the terminal portion of the catheter. The port is aligned with an ostium of a side branch of the bifurcated vessel to allow the passage of a stent delivery device, such as a balloon catheter having a stent crimped thereon, into the side branch. Radiopaque bands are positioned on opposite ends of the port. A positioning balloon is included on a surface of the catheter opposite the port and is selectively inflatable to position the radiopaque bands adjacent the side branch ostium. The radiopaque bands are referenced to place the stent proximate the side branch ostium.

    摘要: A system for delivering a medical device, such as an angioplasty balloon, includes two catheter shafts. The distal portion of a first shaft includes a first balloon and is narrower than the proximal portion. A second catheter shaft includes a second balloon and is connected to a medial portion of the first shaft. The second shaft includes a guidewire passageway which is in communication with the passageway of a third shaft that is removably connected to the first shaft. The distal tips of the first and second balloons are connected together to allow the system to be advanced to an anatomical site using a single guidewire. A second guidewire may be used to separate the distal ends of the balloons and to position the balloons at vascular bifurcation. A stent can be crimped onto the balloons such that inflation of the balloons implants the stent within the bifurcation.

    摘要: The invention includes a catheter having an elongate main body having a proximal section and a distal section. The elongate main body further includes a plurality of stiffening members disposed along the length of the elongate main body. At least one stiffening member includes a plurality of clusters including helical turns or rotations disposed circumferentially about a tubular member and along the length of the cluster. The clusters can be configured to vary flexibility along the length of the tubular member. The catheter can include a sheath having a stationary section and a retractable section.
