摘要： A catheter assembly for an intravascular ultrasound system includes a catheter insertable into patient vasculature via a guidewire. A watertight imaging core is disposed in the distal end of the catheter. The imaging core includes a motor, at least one fixed transducer, and a signal redirection unit. The motor includes a magnet configured and arranged to rotate upon generation of a magnetic field by magnetic field windings. The signal redirection unit is coupled to the magnet such that rotation of the magnet causes a corresponding rotation of at least a portion of the signal redirection unit. The signal redirection unit includes a tilted mirror that redirects acoustic signals transmitted from the fixed transducer to patient tissue. At least one transducer conductor and at least one stator conductor are electrically coupled to the imaging core and in electrical communication with the proximal end of the catheter.

摘要： A bifurcated stent that is positionable adjacent to a branched body vessel. The stent includes a number of stent members (8) at least some of which have slits (40) extending through them. The slits are positioned relative to the tensile and compressive forces imposed by stent expansion to enhance the flexibility of the stent members. The slits can be positioned to increase stent compression about a catheter, increase how far the stent can be bent during catheter deployment, and allow specific portions of the stent to have improved flexibility. The slits can allow the stent to assume a bent shape, and compensate for rigidity imposed the bifurcating side branch. The slits can be combined with curved sections to create a highly flexibly stent.
