    摘要: An epicardial patch includes an extracellular matrix (ECM) and a plurality of electrodes. The isolated ECM is configured for epicardial attachment over a myocardial region including an injured area to control post-injury remodeling of the myocardial region. The plurality of electrodes is configured for delivering electrical stimulation to enhance the effect of the isolated ECM in remodeling control by altering workload and stress on the myocardial region.

    摘要: A method of manipulating a catheter assembly involves providing an inner catheter member movably disposed within an outer catheter member. At least a distal end portion of the inner catheter member has a stiffness greater than that of at least a distal end portion of the outer catheter member. The distal end portion of the outer catheter member includes a deflectable distal end. The method further involves advancing the inner catheter member through the outer catheter member toward the deflectable distal end of the outer catheter member, and longitudinally displacing the distal end portion of the inner catheter member relative to the deflectable distal end of the outer catheter member to alter a shape of the deflectable distal end.

    摘要: A seal adapted for use with medical devices is provided. The medical device may be a lead having a distal tip adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity. The lead assembly in one embodiment includes an atraumatic tip. A seal is provided within the lead tip assembly, which prevents or limits further entry of fluids through the lead tip. The lead may be a left ventricular lead with a hemostasis mechanism provided therewithin.

    摘要: A lead having an atraumatic tip is adapted for implantation on or about the heart within the coronary vasculature and for connection to a signal generator. The lead is constructed and arranged so that when it is implanted, the electrodes are housed in the coronary vasculature and are biased toward a vessel wall by a preformed biased portion. Near the distal end, the lead has an optional tapered portion and a flexible portion, where the flexible portion is more flexible than the biased portion.

    摘要: Systems and methods for steering one or more stimulation fields to a selected nerve target, thereby optimizing one or a combination of low stimulation thresholds, desired therapy outcomes, or a minimization of adverse stimulation side-effects. An array of electrodes disposed, at least in part, on two or more neural stimulation leads are used for steering the stimulation fields to the selected nerve target and are positioned adjacent the selected target. The stimulation may be titrated based on, among other things, a detected physiologic response to the applied stimulation.
