Abstract

An intra-aortic catheter apparatus for kidney perfusion and preservation has a catheter with a tube having an intermediate part which forms a permeable zone located so that in an inserted condition of the catheter the permeable zone is exactly located at a renal parahiliar area, a distal balloon located at a distal caudal part of the tube and formed so as to obstruct circulation in an aorta when being inflated, a proximal balloon located at an end of the tube which is insertable over renal arteries and having such a diameter that upon inflation it also fully obstructs aortic circulation, the balloons being located at opposite sides the of the permeable zone, a first opening provided in the tube and communicating with the permeable zone, a second opening provided in the tube so as to end in the renal parahiliar area, a distal opening communicating with the distal balloon for inflating the latter, and a proximal opening communicating with the proximal balloon for inflating the latter, and a monitoring equipment connected with the catheter.

Claims

1. An intra-aortic catheter apparatus, comprising an intra-aortic catheter including an intra-aortic catheter for kidney perfusion and preservation, comprising a tube having an intermediate part with means forming a permeable zone located so that in an inserted condition of the catheter said permeable zone is exactly located at a renal parahiliar area, a distal balloon located at a distal caudal part of said tube and formed so as to obstruct circulation in an aorta when being inflated, a proximal balloon located at an end of said tube which is insertable over renal arteries and having such a diameter that upon inflation it also fully obstructs aortic circulation, said balloons being located at opposite sides said of said permeable zone, a first opening provided in said tube and communicating with said permeable zone, a second sensor opening provided in said tube and communicating with said permeable zone so as to end in the renal parahiliar area, a distal opening communicating with said distal balloon for inflating the latter, and a proximal opening communicating with said proximal balloon for inflating the latter;

and an a monitoring equipment connected with said catheter and including an electrocardiographer, a plurality of sensors connected with said sensor opening and having an output toward said permeable zone connected with hemodynamic and biochemical set for providing data on arterial temperature and pressure so as to simultaneously and continuously monitor the arterial pressure at the renal parahiliar area;

means for taking a blood sample through said first opening and determining gasometry, hematological and biochemical parameters and afterwards determining further biochemical and pharmacological data, a pumping device connected to said distal and proximal openings to control and carry out inflation of said balloons first activating the inflation of said distal balloon whenever a renal parahiliar pressure decrease or a reversible heart arrest is detected and activating the inflation of said proximal balloon in the event of an irreversible heart arrest, a perfusion pumping set connected with a terminal end of said permeable zone for perfusion of fluid through said permeable zone into kidney while a patient is alive and upon irreversible heart arrest an inflation of said balloons, providing an exanguination system connected with said catheter synchronized with said perfusion pumping set, and computerized registering means connected with said catheter and recording all hemodynamic, hematological and biological variables at every moment of operation of the catheter.

2. An intra-aortic catheter apparatus as defined in claim 1, wherein said tube further comprises an additional opening communicating with said permeable zone for inserting a guiding wire.
