    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: 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 dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways.
