    摘要: The invention is directed to a guidewire having a distal section with multiple distally tapered core segments with at least two contiguous distally tapering core segments in which the most distal tapered core segment preferably has a greater degree of taper than the proximally contiguous tapered core segment. The invention is also directed to an elongated intracorporeal device, preferably a guidewire or section thereof, that has a core member or the like with a plurality of contiguous tapered segments having taper angles that are configured to produce a linear change in stiffness over a longitudinal section of the device. The device may also have a core section with a continuously changing taper angle to produce a curvilinear profile that preferably is configured to produce a linear change in stiffness of the core over a longitudinal section of the device.

    摘要: A dual lumen guidewire support catheter for accurately crossing a chronic total occlusion in a vessel is disclosed. The dual lumen guidewire support catheter includes a first lumen portion and a second lumen portion sharing a common side and a common distal end. The first lumen portion can be a rapid exchange or over-the-wire portion, while the second lumen portion is an over the wire portion. One or both of the portions can include a discontinuity to enable removal of a guidewire following placement through or at an occlusion or lesion.

    摘要: A motor controller for providing a constant rate of change of pressure during inflation and deflation of an expandable member of a catheter for use in a body lumen by an automated inflation system is disclosed. The system conforms the rate of change of pressure to a set point value by means of a feedback loop controller, and makes possible consistent inflations and deflations using an automated system regardless of variations in catheter volume and compliance characteristics. Safety features such as maximum pressure and balloon rupture alarms are also disclosed.

    摘要: A support catheter that can be used to aid positioning of a guidewire and other medical devices. The support catheter includes a catheter body having a length, and a supporting structure formed or disposed in or on the catheter body. The catheter support structure, whether alone or in combination with the other portions of the support catheter, provides flexibility, stiffness, and torqueability to the support catheter.

    摘要: A balloon catheter with a balloon having first and second tapered sections adjacent the distal and proximal ends of the working length of the balloon, respectively, and third and fourth tapered sections adjacent the first and second tapered section, respectively. The first and second tapered sections taper at a first angle to a smaller outer diameter than the inflated outer diameter of the working length inflated within a deployment range of the balloon, and the third and fourth tapered sections taper at a second angle larger than the first angle. The balloon has expandable retention sections proximal and the distal to the working length of the balloon for inhibiting migration of a stent mounted on the balloon.
