A drive transmitting mechanism configured to rotate the photosensitive drum of a color copier has a driving shaft, a driven shaft, and first and second coupling members. The first coupling member has a projection extending in a diametrical direction. The first coupling member is attached to the driving shaft, with amount of freedom to oscillate in a direction intersecting at right angles to the lengthwise direction of the projection. The second coupling member has a recess in which the projection is fitted. The second coupling member is attached to the driven shaft, with amount of freedom to oscillate in the lengthwise direction of the recess. The first and second coupling members oscillate in the diametrical direction and slide on the contacting surface in a diametrical direction intersecting at right angles to the diametrical direction, thus suppressing the rotational speed change of the driven shaft, which results from the de-centering and declination between the driving shaft and the driven shaft.

This is a surgical device and a method of using it. In particular, the device is one for reinforcing the pericardial sac surrounding the heart to assist in the treatment of congestive heart failure. The device, generically, is an enclosure having an interior and an exterior. The interior surface is made in such a way that it tends not to or does not form adhesions with or accept ingrowth with the myocardial tissue of the epicardium. The exterior surface of the device, in contrast, is adapted to adhere to or to ingrow with or otherwise attach sufficiently to the pericardium so that it reinforces that membrane or structure. The nature of the device is that it tends not to allow the pericardium to expand further with time.

This device helps to prevent further declination of the heart during congestive heart failure. The device is preferably introduced into the pericardial space and into the inner surface of the pericardium using transcutaneous or minimally invasive techniques.
