Abstract: A system and method that provides controlled bilateral stimulation to a patient in response to physiological feedback to initiate and/or accelerate the onset of sleep and to maintain the sleep state after the onset of sleep. The system induces bilateral stimulation through stimulation modules that are coupled to opposite lateral sides of the patient's body. The stimulation modules stimulate the patient's body bilaterally through a sequence of stimulations that alternate from one side of the patient's body to the other with a pause between each successive stimulation. The system controls the duration of the stimulations, the intensity of the stimulations and the period of time between successive stimulations in response to feedback from physiological sensors. The sensors are coupled to the patient and provide physiological information which initiates or terminates the bilateral stimulations, and/or modifies the characteristics of the stimulations.

Abstract: A lead for monitoring or stimulating cardiac activity is provided. The lead is adapted for implantation on or about the heart within the coronary vasculature and for connection to a signal generator. The lead body has one or more electrodes associated therewith. The lead is constructed and arranged so that when it is implanted, the electrodes are housed in the coronary vasculature and urged into intimate contact a vessel wall.

Abstract: 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.
