    摘要： Synchronized stimulation of cardiac tissue can be implemented by implanting two or more rectifier-based AM receivers into different positions within a subject's heart. Each receiver is tuned to a different frequency, and generates an output signal that is capable of stimulating cardiac tissue when a signal at the corresponding tuned frequency arrives at the receiver. An AM transmitter can activate any given one of the receivers by transmitting a signal into the subject's body at the proper frequency. A controller controls the transmitter by commanding the transmitter to transmit pulses of AC at different frequencies at different times, so that when those pulses are received by the correspondingly-tuned receivers, each of the receivers will generate respective output signals that stimulate respective parts of the heart at respective times to promote improved cardiac performance.

    摘要： An apparatus for improving the cardiac function and cardiac output of a patient comprises a waveform generator that generates alternating voltage pulses, a controller to control the timing of the pulses, and electrodes that deliver the alternating voltage pulses to the patient's body. The alternating voltage pulses induce a field of alternating current pulses within the patient's body. As the pulses pass through a cardiac ventricle (or atrium), they increase the concentration of Ca2+ at the appropriate cardiomyocyte sites, and thereby increase the strength and duration of the ventricular (or atrial) contractions. In alternative embodiments, the electric field may be used to strengthen the contractions of non-cardiac muscle (e.g., skeletal muscle).

    摘要： Stents which are inserted into a body lumen preferably are made of materials which are not radiopaque enough, such as stainless steel 316L. X-ray visualization of a stent enables an accurate positioning of the stent and also a follow-up of its functioning within the patient's body. The radiopaque markers described here are rivets made of a material which is more radiopaque than the stent substance so the location of the stent can be identified. Preferably the stents are heat treated so that atoms from the stent material migrate into the marker material and vice versa.
