    摘要： The present invention is a myocardial lead attachment system for securing a lead within the myocardium. The attachment system includes an anchor configured to engage the heart, a tether coupled to the anchor and a lead body. The lead body has a proximal end, a distal end, a lumen for accepting the tether and a lock housing in the lumen. A lock structure is on the tether and mates with the lock housing and restrains motion of the lead with respect to the tether in either of a proximal or a distal direction.

    摘要： A device and method for accessing a pericardial space of the heart includes a shaft having a cavity at a distal end, a suction lumen terminating in a distal port within the cavity and a hollow needle having a distal tip extending into the cavity. The cavity may be a recess in the shaft into which the distal tip of the needle fixedly protrudes. In other embodiments, the cavity is formed by an inflatable member positioned at the distal end of the shaft and the needle is slidable relative to the shaft. Suction is applied at the cavity to draw a pericardial bleb. The needle pierces the pericardial bleb for accessing the pericardial space and also facilitates delivery of payloads into the pericardial space.

    摘要： An apparatus includes a flexible lead body extending from a proximal end to a distal end, the distal end having a biased portion having an outer diameter dimensioned to abut a wall of a pulmonary artery, an electrode coupled proximate the distal end, and an implantable pulse generator electrically coupled to the electrode. The implantable pulse generator is adapted to deliver a baroreflex stimulation signal to a baroreceptor in the pulmonary artery via the electrode.

    摘要： Certain embodiments of the present invention provide for a system and method for modeling S-distortion in an image intensifier. In an embodiment, the method may include identifying a reference coordinate on an input screen of the image intensifier. The method also includes computing a set of charged particle velocity vectors. The method also includes computing a set of magnetic field vectors. The method also includes computing the force exerted on the charged particle in an image intensifier. Certain embodiments of the present invention include an iterative method for calibrating an image acquisition system with an analytic S-distortion model. In an embodiment, the method may include comparing the difference between the measured fiducial shadow positions and the model fiducial positions with a threshold value. If the difference is less than the threshold value, the optical distortion parameters are used for linearizing the set of acquired images.
