Patent ID: 8303567

Claim:
A method of systemically transferring a macromolecular complex to muscle cells of a subject, said method comprising the step of: placing a patient under total circulatory arrest using a first heart-lung cannulae and a second heart-lung cannula, each said cannula being placed in a suitable vessel through a cannulation site in each vessel; lowering the patient's temperature to 15 to 18° C.; partially exsanguinating and decannulating the patient from the first and second heart-lung cannulae; introducing a first balloon catheter and a second balloon catheter in the cannulation sites, wherein upon inflation the first balloon catheters occludes the aorta and the second balloon catheter occludes the venae cavae to preclude backflow; inflating the balloon catheters to a pressure exceeding that applied from cannulae in extremities of the patient; and simultaneously applying the macromolecular complex in solution to all four of the patient's extremities via the cannulae located therein; wherein each of said first and second balloon catheters comprises: an inflatable balloon having an interior, said balloon being expandable radially without significant distal expansion, and, when inflated, said balloon forming an elongate, continuous, cylindrical tube having an outer diameter that is substantially constant along a full length of said tube and that is sufficient to abut the walls of a vessel in which it has been inserted to occlude blow flow therethrough; a flexible cannula having a distal end and a proximal end and extending along an axis having an internal channel for the controlled application of fluid under pressure; said balloon being attached to the cannula at at least two points, one point of attachment being adjacent to the distal end of the cannula and a second point of attachment being adjacent to the proximal end of the cannula, such that when inflated, said balloon expands radially to abut the walls of the vessel in which it has been inserted and to occlude the aortic space or the venae cavae.
