Abstract: An improved balloon catheter has a catheter body with an expandable member, such as a balloon, mounted to the exterior surface thereof. Preferably, means for preventing sticking of the expandable balloon to the exterior surface of the catheter body are provided. In one aspect, the catheter has an expandable member, preferably a balloon, positioned substantially equidistant from the proximal and distal ends of the catheter body. The retention catheter is positioned externally of the heart and partially surrounds the heart so that the balloon is positioned immediately adjacent the coronary sinus and when inflated, the balloon bears against the coronary sinus and at least one of the inferior vena cava and diaphragm thereby preventing inadvertent movement or removal of the RCSP catheter from the coronary sinus.

Abstract: A method and tools for forming a hermetically sealed container from a previously used can characterized by removing a portion of a top of a can radially inward of an inward edge of an annular depression of the top to form an opening, placing a continuous sealing member in the annular depression, assemblying a lid on a top with the lid having an annular shoulder for engaging the sealing member and an annular flange which has a reversed bend and extends from the shoulder over the rim to provide an annular skirt which extends along the outer surface of the rim and terminates therebelow, forcing the lid into sealing engagement with the sealing member, and while holding the lid in the sealing engagement, crimping the annular skirt beneath the rim to hold the lid in the sealing engagement.
