摘要： A multiple balloon catheter for use in a vessel of a patient and for use with an inflation/deflation device. A flexible elongate tubular member with proximal and distal extremities has a distal balloon mounted on the distal extremity of the flexible elongate tubular member. Coaxial inner and outer balloons are mounted on the distal extremity of the flexible elongate member proximal of the distal balloon. The flexible elongate tubular member has balloon inflation lumens therein in communication with the interiors of the distal balloon and the inner and outer coaxial balloons. A manifold is secured to the proximal extremity of the flexible elongate tubular member in communication with the inflation lumens and is adjusted to be coupled to the inflation/deflation device.

摘要： The present invention relates to a combination device comprising two catheters, or a dual catheter assembly, for use in vascular procedures wherein the shaft of the first catheter functions as a guidewire for the second catheter. The dual catheter assembly comprises a first balloon catheter and a second balloon catheter wherein the second balloon catheter is slidably disposed on the shaft of the first balloon. In preferred embodiments, the first catheter is a low profile balloon on a wire catheter and the second catheter is a full size balloon catheter having a plurality of balloons mounted thereon. Optionally, a stent is carried by at least one of the balloons on the second catheter. In more preferred embodiments, the second catheter includes a manifold that may be used to inflate and deflate any combination of the plurality of balloons via a single port. The dual catheter assembly of the present invention is especially useful in vascular procedures such as angioplasty, progressive/multiple angioplasty, and stent delivery.

摘要： Guide wire for use in a medical procedure and for use with a power supply comprising a solid core wire having proximal and distal extremities. The proximal extremity has a predetermined diameter. At least a portion of the distal extremity has a reduced size with respect to the predetermined diameter. A flexible coil is secured to the distal extremity of the core wire and extends over the portion of the core wire having a reduced size. An actuator member is disposed proximal of the coil and extends along the core wire. Electrical conductors extend from the proximal extremity of the core wire to the actuator member for supplying heat to the actuator member. The actuator member is formed of a temperature activated metal alloy having a Young's modulus of 4.times.10.sup.6 to 14.times.10.sup.6 psi which increases in stiffness when heat is supplied thereto to increase the stiffness of the guide wire proximally of the coil.

摘要： A guide wire with extension capability for use in a medical procedure having a guide wire and a guide wire extension. The guide wire comprises a flexible elongate cylindrical member having proximal and distal extremities. A portion of the distal extremity is formed of a material having high torquability and high pushability. The guide wire extension comprises a flexible elongate cylindrical member formed of a shape memory material. A major portion of the flexible elongate cylindrical member of the guide wire extension has a shape memory in the form of a coil so that when it is free it will assume a shape memory coil. A junction is formed between the proximal extremity of the guide wire and the distal extremity of the guide wire extension for connection of the guide wire extension to the guide wire.
