Abstract
An apparatus and a method to treat a disease process in a luminal structure. A dual-balloon catheter for treating a disease process in a luminal structure of a patient comprises an inner balloon, an outer balloon substantially concentric with and substantially surrounding the inner balloon, an inner balloon fluid delivery lumen in fluid connection with the inner balloon, and an outer balloon fluid delivery lumen in fluid connection with the outer balloon.
Claims13
A dual-balloon catheter for treating a disease process in a luminal structure of a patient, comprising:
- an inner balloon;
- an outer ballon substantially concentric with and substantially surounding the inner ballon;
- an inner balloon fluid delivery lumen in fluid connection with the inner balloon;
- and
- an outer balloon fluid deliverly lumen in fluid connection with the outer balloon.
A method for treating a disease process in a luminal structure of a patient, comprising:
- insering into the luminal structure a dual-balloon catheter including an inner balloon, an outer ballon substantially concentric with and substantially surounding the inner ballon, an inner balloon fluid delivery lumen in fluid connection with the inner balloon, and an outer balloon fluid deliverly lumen in fluid connection with the outer balloon;
- and
- inserting a radioactive fluid into at least one of the inner ballon and the outer balloon through the inner balloon fluid delivery lumen and the outer balloon fluid delivery lumen, respectively.
An indiflator for inserting fluid into a balloon catheter, comprising:
- an elongated tube for holding the fluid, the elongated tube having a first end and a second end;
- the first end of the elongated tube having a wall accross the tube with a port therein for providing a fluid passage between an interior of the tube and an exterior of the tube;
- a plunger assembly including a plunger head with a first face and a second face and a plunger stem having first and second ends;
- the plunger head being adapted to slide within the tube and being connected at the first face to the first end of the plunger stem;
- lock means disposed at the second end of the tube for accepting and releasably locking the plunger stem, the second end of the plunger stem being disposed outside the tube;
- and
- a pressure valve disposed adjacent the second end of the plunger stem and being operatively connected to a pressure transucer on the second face of the plunger head facing the first end of the tube, whereby the pressure valve displays a pressure in an area of the tube between the first end of the tube and the second face of the plunger head.
