    摘要: Annuloplasty rings and methods for inserting annuloplasty rings are herein disclosed. The annuloplasty ring has a ring shell and a plurality of anchoring fasteners for anchoring the ring shell to adjacent hear tissue. To maintain the shape of the annuloplasty ring upon attachment of the ring to the patient's heart, a hardening polymer is inserted into the ring shell, which is permitted to cure, thereby providing support for the annuloplasty ring and the patient's heart valve.

    摘要: Techniques are described that allow intravascular ultrasound (“IVUS”) imaging of patient tissue, e.g., a blood vessel wall, to be performed at one or more angles selected by a clinician, for example. In one example, a method includes receiving user input, via interaction with a user interface, that defines a range of angles through which a scan will be performed, determining, based on the received user input, at least one current value to be applied to at least one lead of a stator of a motor, controlling application of the at least one current to the at least one lead of the stator in order to rotate a rotor of the motor through the range of angles, and through the range of angles, receiving and processing electrical signals from at least one transducer to form at least one image.

At least one impeller is coupled to the at least one magnet. Rotation of the at least one magnet causes a corresponding rotation of the at least one impeller. An anchoring arrangement is coupled to the pumping sleeve. The anchoring arrangement is configured and arranged to anchor the pumping sleeve at a target pumping location when the pumping sleeve is inserted into patient vasculature.

    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.
