摘要： A pacing lead for implantation in a coronary sinus having an opening and a wall defining an interior and presenting a diameter dimension. The pacing lead includes an elongated lead body, a resilient fixation element, and at least one electrode on either the lead body or the fixation element. The fixation element extends from the pacing portion and defines a loop structure laterally adjacent the pacing portion. The loop structure presents a predetermined width dimension greater than the diameter dimension of the coronary sinus, wherein when the loop structure is inserted into the opening of the coronary sinus, the loop structure is laterally compressed by the wall of the coronary sinus and the electrode is biased against the wall of the coronary sinus.

摘要： In one embodiment, the present invention provides a cardiac lead device including a fixation mechanism slidably attached to the lead such that when the fixation mechanism is expanded into contact with a body lumen, the lead may be moved relative to the fixation mechanism if desired. Such lead movement may be limited by complimentary structure on the lead body and the fixation mechanism that prevents the lead from moving unless sufficient force is applied to the lead.

摘要： Systems according to the invention employ an acceleration sensor to characterize displacement and vibrational LV motion, and use this motion data to characterize the different phases of the LV cycle for analyzing LV function. Systems may identify a target pacing region or regions in the LV or RV using the acceleration sensor by localizing regions of late onset of motion relative to the QRS, or isovolumic contraction, or mitral valve closure, or by pacing of target regions and measuring LV function in response to pacing. Systems further provide an implantable or non- implantable acceleration sensor device for measuring LV motion and characterizing LV function. An implantable myocardial acceleration sensing system ("IAD") includes at least one acceleration sensor, a data acquisition and processing device, and an electromagnetic, e.g., RF, communication device. The IAD may be integrated into the pacing lead of a CRT device and can operate independently of the CRT IPG. The acceleration sensors may also be used to acquire and analyze the frequency dynamics associated with the isovolumic contraction phase ("ICP"). This information can be used to characterize heart function; optimize therapy for cardiomyopathy, including CRT therapy (including pacing intervals and required pharmacologic therapy); and to optimize CCM therapy. In addition, this information can be used to identify target pacing regions for CRT lead placement. Further, analyzing the frequency dynamics can be used to characterize pathologic heart vibrational motion, such as mitral regurgitation and the third or fourth heart sound, and the response of this motion to therapy for cardiomyopathy.

摘要： A coronary sinus locater sheath is stabilized in the vicinity of the coronary sinus by a guidewire exiting the side of the sheath near the distal end and inserted into an identifiable anatomical feature. The procedure includes (1) inserting the guide sheath into a vein, (2) advancing the sheath until the right atrium is entered, (3) advancing the sheath into the IVC, (4) extending a guidewire through a port near the sheath's distal end , (5) retracting the sheath above the IVC into the right atrium, (6) articulating or rotating the sheath until the sheath is near the coronary sinus ostium, while the sheath is stabilized by the guidewire. Thus the sheath can be positioned near the coronary sinus ostium limiting the motion imparted to the sheath from the beating heart. An imaging catheter may be used in conjunction with the sheath. The sheath or catheter may include pacing electrodes.
