    摘要: Techniques for minimizing interference between first and second medical devices of a therapy system may include providing an outer housing for at least one of the medical devices that comprises an electrically insulative layer formed over at least the electrically conductive portions (e.g., an electrically conductive layer) of the housing, or providing an electrically insulative pouch around an electrically conductive housing of at least the first medical device. The electrically insulative layer or electrically insulative pouch may reduce or even eliminate shunt-current that flows into the medical device via the housing. The shunt-current may be generated by the delivery of electrical stimulation by the second medical device. In some examples, the techniques may also include shunt-current mitigation circuitry that helps minimize or even eliminate shunt-current that feeds into the first medical device via one or more electrodes electrically connected to the first medical device.

    摘要: A method of operating a cardiac pacing device that optimizes the mechanical heart rate using coordinated potentiation therapy while maximizing the opportunity for intrinsic AV conduction to occur. The method may include adjusting the timing of extra stimulus intervals during coupled or paired pacing to promote AV conduction and to effect changes in rate according to certain embodiments of the invention. Other embodiments may include adjusting the atrial pacing rate to achieve a desired target rate consistent with AV conduction. A mode switch to a dual-chamber pacing mode may be provided according to certain embodiments of the invention to ensure a ventricular rate that meets or exceeds a minimum mechanical rate.

    摘要: An implantable medical device (IMD) provides for adaptive timing of the delivery of cardioversion shocks. In particular, the invention IMD provides for an adaptive cardioversion synchronization delay with respect to a cardiac event, such as a sensed P-wave or R-wave. When cardioversion with a first synchronization delay fails to terminate a tachycardia, for example, cardioversion may be attempted again with a second synchronization delay. The IMD may keep track of whether each synchronization delay is effective in terminating the tachycardia, and may employ a historically effective synchronization delay when applying cardioversion therapy to treat a subsequent tachycardia episode.

    摘要: A system for treating a body vessel may include a delivery device and a prosthesis retained on the delivery device. The prosthesis may include a main body and first and second legs each extending from the main body. The main body may include a lumen, and the first leg may include a lumen in fluid communication with the lumen of the main body. The second leg may include a tubular graft body and a stent attached to the graft body. The prosthesis may have a predeployment configuration in which the graft body of the second leg is inverted into and positioned within the lumen of the first leg, and the stent is positioned outside of the inverted graft body. The prosthesis may have a deployed configuration in which the second leg extends outward from the main body, and the stent is positioned within a lumen of the graft body.
