    摘要: Methods and apparatus for supplying retrograde perfusion of chronically ischemic myocardium by forming one or more transmural passageways between a cardiac chamber and the coronary venous vasculature. The placement, size and number of the passageways are selected, and portions of the venous vasculature or coronary ostium optionally partially or completely occluded, to maintain a parameter related to the pressure attained in the venous vasculature to a value less than a predetermined value.

    摘要: Apparatus and methods are provided for use in open surgical and transluminal methods for supplying long-term retrograde perfusion of the myocardium via a conduit disposed between the left ventricle and the coronary sinus. In a first method, an opening is formed between the left ventricle and the coronary sinus, and the coronary ostium is partially occluded using a stent that prevents the pressure in the coronary sinus from exceeding a predetermined value. In an alternative method, a first end of a conduit is inserted transeptally through the right atrium and obliquely into the posterior septal endocardium of the left ventricle via the posterior pyramidal space, while a second end of the conduit is inserted into the coronary sinus via the coronary ostium. A pressure-limiting valve is included in the conduit. In either method, the outlet from the left ventricle to the coronary sinus may include a one-way valve to prevent backflow from the coronary sinus into the left ventricle during cardiac diastole.

    摘要: Apparatus and methods for perfusing ischemic myocardium, and optionally, for reducing the load on a patient's left ventricle, are provided using a inlet conduit having an inlet end configured for insertion into an oxygenated blood source, including without limitation, the left atrium, left ventricle, aorta, pulmonary vein, subclavian artery, brachiocephalic artery, radial artery or femoral artery, coupled to an outlet conduit having an outlet end configured for insertion into the coronary venous vasculature via the coronary ostium. The inlet conduit may include a stylet or elastomeric sleeve that facilitates placement, while the outlet conduit may include a valve for limiting a peak pressure attained in the coronary venous system. A motor-driven or hydraulically-actuated pump optionally may be coupled in the flow path, and control circuitry provided to control the pump with a user selected duty cycle.

    摘要: The present invention is a method and device, which is suitable for use in an operating theater just prior to implantation, for selectively applying a medical coating to an implantable medical device, for example a stent. Disclosed is a device for use with a stent deployed on a catheter balloon. The device is configured to apply a medical coating of a desired thickness to the surface of a stent only. This is done by use of a drop-on-demand inkjet printing system in association with an optical scanning device. The device is further configured so as to, if necessary, apply a plurality of layered coats, each layered coat being of a different coating material, and if appropriate, different thickness. The section of the housing in which the stent is held during the coating procedure is detachable from the housing base. The detachable housing section may be easily cleaned and re-sterilized or simply disposed or simply disposed of.
