摘要:
A device for modifying the shape of a mitral valve annulus. In one embodiment, the device includes a connector disposed between first and second anchors, the first and second anchors each adapted to be deployed in a coronary sinus adjacent the mitral valve annulus to anchor the device in the coronary sinus; and an actuation element adapted to receive a proximally or distally directed actuation force from an actuator and to transmit the actuation force to the first and second anchors simultaneously. The invention also includes a system for modifying the shape of a mitral valve annulus, including a percutaneous deployment apparatus, including an actuator; and a percutaneous mitral valve annuloplasty device with a connector disposed between first and second anchors, the first and second anchors each adapted to be deployed in a coronary sinus adjacent the mitral valve annulus to anchor the device in the coronary sinus; and an actuation element adapted to receive a distally proximally directed actuation force from the actuator and to transmit the actuation force to the first and second anchors simultaneously. The invention also includes a method of using such devices and systems.

摘要:
A system and method of controlling the pressure within a surgical tourniquet so as selectively to occlude blood flow within a portion of a limb of a patient, wherein the pressure within an inflatable cuff surrounding a portion of a limb of a patient is changed by automatically opening a first valve connected to a controller and located within a first conduit between an inflatable bladder and the inflatable cuff, when the pressure in the inflatable cuff is different from that in the inflatable bladder. In another aspect, a system and method of controlling the pressure within a surgical tourniquet so as selectively to occlude blood flow within a portion of a limb of a patient within five seconds. In another aspect, a system and method of detecting a leak in a surgical tourniquet. In another aspect, a surgical tourniquet that, from an inflated state, may enter a deflated state, a set state, a default display state, or an off state. In another aspect, a surgical tourniquet mounted in a housing selectively closed around a pole, wherein the center of gravity of the housing is located within the pole, In another aspect, a surgical tourniquet controlled by means of a graphical user interface. In another aspect, a method of detecting a stuck solenoid valve in a surgical tourniquet.

摘要:
A localization mechanism, or fixture, is used in conjunction with a breast coil for breast compression and for guiding a core biopsy instrument during prone biopsy procedures in both open and closed Magnetic Resonance Imaging (MRI) machines. The localization fixture includes a three-dimensional Cartesian positionable guide for supporting and orienting an MRI-compatible biopsy instrument, and in particular a sleeve, to a biopsy site of suspicious tissues or lesions. A depth stop enhances accurate insertion, prevents over-insertion or inadvertent retraction of the sleeve. The sleeve receives a probe of the MRI-compatible biopsy instrument and may contain various features to enhance its imagability, to enhance vacuum and pressure assist therethrough, etc.
