Abstract
Embodiments of the invention provide apparatus, systems and method for introducing fluids into a body cavity for treatment. One embodiment provides an apparatus for treating a patient including an access device for insertion into the peritoneal cavity of the patient including an infusion member in a lumen of the access device. An oxygenated solution may be infused and removed into and out of the cavity via the infusion member.
Claims23
A method of cooling a body cavity of a patient, comprising:
- monitoring a depth of an access device inserted within a body cavity, the access device having a valve for controlling a fluid flow between the access device and the body cavity;
- expanding the body cavity into a distended shape;
- introducing a hypothermic solution through a lumen of the access device and into the body cavity such that the body cavity is cooled while expanded into the distended shape;
- controlling infusion of the hypothermic solution into the body cavity via an electronic controller and the access device;
- and
- controlling removal of the hypothermic solution from the body cavity via the electronic controller and the access device at a removal rate that keeps a sufficient proportion of the hypothermic solution in the cavity to maintain the cavity in the distended shape.
