摘要： An intravascular catheter system and method of manufacture for implanting a radially expandable stent within a body vessel. The catheter system includes a shaft defining an inflation lumen in fluid communication with a balloon on the distal end of the shaft. A stent is mounted coaxially upon a balloon. The balloon has ridges impressed in the outline of the stent for at least a portion of the stent. The ridges are sized to receive the stent so as to cause the balloon to expand evenly and the stent to deploy uniformly. In an alternative embodiment the balloon may additionally have a polymeric surface layer exhibiting a higher coefficient of friction than the underlying material against the stent material. The surface layer may be provided as a high friction polymeric coating on a formed balloon or as a coaxial extrusion of a high friction polymeric material over the underlying balloon tubing material. In a further embodiment the balloon may have the polymeric surface layer exhibiting a higher coefficient of friction than the underlying material against the stent material but without the ridges.

摘要： A medical device, system and method are provided for thermal medical treatment. A medical device for cryogenic treatment may include a tip and a thermal guard or shield. The tip may be at a distal end of a catheter shaft, having a distal surface and lateral surfaces. The thermal guard may be coupled to the catheter proximal of the distal tip, surrounding the longitudinal axis and exposing the distal surface, to resist heat transfer from body fluids to the lateral surfaces of the tip. An efficiency of heat transfer from selected tissue to be treated to the distal surface of the cryogenic tip is thereby increased.

摘要： The invention provides a method and device for heating or cooling a surrounding fluid in a feeding vessel. The device includes a catheter assembly capable of insertion to a selected feeding vessel in the vascular system of a patient. The assembly includes a heat transfer element at a distal end of the catheter assembly, the heat transfer element having a plurality of exterior surface irregularities shaped and arranged to create turbulence in a surrounding fluid, the surface irregularities having a depth at least equal to the boundary layer thickness of flow of the surrounding fluid in the feeding vessel. The assembly also includes a supply catheter to deliver a working fluid to an interior of the heat transfer element, a return catheter to return a working fluid from the interior of the heat transfer element, and a drug delivery catheter running substantially parallel to the axis of the catheter assembly. The method includes selectively controlling the temperature of a selected volume of blood in a patient by introducing a catheter assembly into a blood vessel feeding a selected volume of blood in a patient and delivering a working fluid through a supply catheter in the catheter assembly and returning the working fluid through a return catheter in the catheter assembly. Heat is transferred between a heat transfer element forming a distal end of the catheter assembly and the volume of blood in the feeding vessel. A liquid, such as a drug, is delivered through a drug delivery catheter to the volume of blood in the feeding vessel.
