    摘要： An active implantable medical device having an RF telemetry circuit. The device is in particular a stimulation, resynchronization, defibrillation and/or cardioversion device. It includes a principal circuit, an RF telemetry auxiliary circuit and a supply battery for the principal and auxiliary circuits. It is envisaged to have between the supply battery and the auxiliary circuit a regulating circuit including an accumulator of electric power coupled with the auxiliary circuit to deliver a current ready to feed the auxiliary circuit, and a load circuit coupled with the supply battery to maintain the accumulator on a predetermined level of load.

    摘要： Methods and apparatus for providing a sufficiently stable power to a load in an energy transfer system that transfers energy from one side of a physical boundary to another side of the boundary. In one example, a power supply and a primary winding are located on a first side of a physical boundary (e.g., external to a body), and a secondary winding and the load are located on a second side of the physical boundary (e.g., internal to the body). A primary voltage across the primary winding is regulated so as to provide a sufficiently stable output power to the load notwithstanding changes in the load and/or changes in a relative position of the primary winding and the secondary winding. One aspect of the invention relates to energy transfer methods and apparatus for use in connection with the human body. In particular, one example of the invention includes a transcutaneous energy transfer (TET) system for transferring power from a power supply external to the body to a device implanted in the body.

    摘要： An irrigator (20) useful for surgical and medical procedures. The irrigator includes a handpiece (22) to which a tip assembly (30) is attached. The tip assembly includes a discharge tube (32) through which irrigating fluid is discharged. A spray head (422) with spaced-apart shoulders (422) is moveably attached to the front of the discharge tube. When the spray head is in a first position, the shoulders do not interfere with the discharge of irrigation fluid. When the spray head is in a second position, the shoulders are in registration over the discharge openings; the discharged irrigation fluid is dispersed by the shoulders. A spray shield (181) is disposed over the discharge tube. The irrigation fluid defused by the spray head shoulders strikes the spray shield which further diffuses this discharge.

    摘要： The invention concerns a current-generating apparatus for supplying at least two probes designed to be applied to a part of the human body for the purpose of therapeutic treatment in the field of biophysics and physiology. This apparatus comprises a self-contained electrical power supply source (2) suitable for delivering a constant voltage, a constant current generator (18), a frequency-generator (10, 19) suitable for transforming the constant current so as to deliver a current in the form of biphase rectangular pulses with zero mean and steep edges, the total duration T of which in .mu.s is substantially between 200 .mu.s and 800 .mu.s, and a delay circuit (12, 14, 15) for delaying the sending of the starts of pulses suitable for triggering a pulse every k .times.15 ms, where k=1 or 4.
