Abstract: Bowls containing food are used by persons who have deficiencies in manual control like infants, the elderly and the incapacitated. Serious accidents may result from spills of the contents of said bowls, in addition to posing a nuisance. The object of this invention is to stabilize said bowls by delimiting the position of the bowl when subjected to stresses related to the said manual deficiencies so that spillage does not occur. Specifically the bowls are stabilized by two suction cups temporarily attached to the bottom of the bowl and a fixed surface, respectively, by ambient air pressure; said cups have rods extending from the necks of the suction cups, respectively, that abut each other in a section of tubing. Thus the bowl has limited rotary motion about the initial central axis of the bowl to allow for involuntary fidgeting with the bowl without causing spills. The maximum diameter of the cup portion of the suction cups is less than the diameter of the flat surface of the bowl.

Abstract: The invention relates to a method and device for recovering therapeutic and diagnostic agents from the venous outflow of a tissue or organ. A method for recovering an agent includes inserting a catheter into a vascular outflow of a tissue or organ, occluding the flow of blood/fluid through the vascular outflow, and withdrawing blood/fluid in the vascular outflow into the catheter to recover at least a portion of the agent administered to the vascular inflow of the organ or tissue.
