    摘要: The intrapericardial lead includes a lead body having a proximal portion and a flexible, pre-curved distal end portion. The distal end portion carries at least one electrode assembly containing an electrode adapted to engage pericardial tissue. The distal end portion further carries a pre-curved flexible wire member having ends attached to spaced apart points along the distal end portion of the lead body, the flexible wire member having a normally expanded state wherein an intermediate portion of the wire member is spaced apart from the distal end portion, and a generally straightened state wherein the wire member and the distal end portion are disposed in a more parallel, adjacent relationship so as to present a small frontal area to facilitate delivery into the pericardial space. The wire member re-expands to its normal state after delivery into the pericardial space to anchor the distal end portion of the lead body relative to the pericardial tissue.

    摘要: A method includes selecting an electrode located in a patient; acquiring position information with respect to time for the electrode, during both acute and chronic states of the electrode, where the acquiring uses the electrode for repeatedly measuring electrical potentials in an electrical localization field established in the patient; calculating an acute state stability metric and a chronic state stability metric for the electrode based on the acquired position information with respect to time; and comparing the acute state stability metric to the chronic state stability metric to decide whether the electrode, as located in the patient in the chronic state, comprises a stable location for delivery of a therapy. The chronic state stability metric of an electrode may be monitored over time to decide whether stability of the electrode has changed.

    摘要: While there have been described herein the principles of the invention, it is to be a mechanical tri-wheel retention assembly for a stair-climbing wheeled vehicle having a tri-wheel assembly. The ass has a tri-lobular roller cam mechanism to retain the tri-wheel at a desired angular position for normal two-wheeled operation, and further includes a spring-loaded roller that is configured to pop out of a locking mode in the event of an overload condition, permitting rotation of the tri-wheel assembly to a next predetermined angular position at which point the tri-wheel assembly will be retained, thus preventing damage to the unit and the locking mechanism. The mechanical tri-wheel retention assembly may further include a solenoid actuator configured to automatically disengage the mechanical tri-wheel retention assembly.
