(54) Title: A VESSEL OR SAC WALL TREATMENT AND A CARDIAC ASSIST DEVICE \-/-% (57) Ahstract 'The present invention provides a method of treating a vessel in a human or animal hody, with method including the 0 steps of: preparing a patient; identifying a site in said vessel requiring treatment; positioning an implatabie device against a portion o of tubular or sac wall of said vessel at said site, whereby load applied to said vessel is borne by said wall (80) and said device, kn said vessel being assisted by said device (410) when said wall and said device acts upon said load, said device including an energy storage means (112) which is charged with a pressure or enemy charge by means of said load being applied to said vessel. The present invention further provides a treatment or assistance device tor operating in or with a tubular or wall sac of a vessel in a human or animal body, said device including a changeable volume portion which is adapted to interact with said vessel so as to modify the volume of said vessel; and an energy storage means (112) functioning with said changeable volume portion (24) whereby a decrease in the volume of said changeable volume portion creates a pressure or energy change in said energy storage means, said pressure or energy change being able to be subsequently released to cause said changeable volume portion to increase in volume.
