Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
In a method of developing immunosuppression in a patient after the transplantation of foreign cells, tissues and organs, using an apparatus having, in continuous fluid communication, an inlet tube, absorbing means for absorbing and thereby removing interferon from the whole blood, and an outlet tube, said method comprising: connecting the inlet tube of said apparatus to a blood vessel of a patient and connecting the outlet tube of said apparatus to a vein of the patient; removing blood from the blood vessel of the patient; passing the removed blood through the absorbing means for absorbing interferon to thereby reduce the amount of interferon in the blood; and returning the blood to the vein of the patient, the improvement comprising: said absorbing means comprising a combined sorbent clearing agent having a first sorbent for absorbing interferon and a second sorbent absorbing T-lymphocytes.
Claim 2
Dependent Claim
141 words
In a method of developing immunosuppression in a patient after the transplantation of foreign cells, tissues and organs, using an apparatus having, in continuous fluid communication, an inlet tube, absorbing means for absorbing and thereby removing interferon from the whole blood, and an outlet tube, said method comprising: connecting the inlet tube of said apparatus to a blood vessel of a patient and connecting the outlet tube of said apparatus to a vein of the patient; removing blood from the blood vessel of the patient; passing the removed blood through the absorbing means for absorbing interferon to thereby reduce the amount of interferon in the blood; and returning the blood to the vein of the patient, the improvement comprising: said absorbing means comprising a combined sorbent clearing agent having a first sorbent for absorbing interferon and a second sorbent absorbing T-lymphocytes.
Claim 3
Dependent Claim
157 words
In a method of developing immunosuppression in a patient after the transplantation of foreign cells, tissues and organs using an apparatus having, in continuous fluid communication, an inlet tube, absorbing means for absorbing and thereby removing interferon from the whole blood, and an outlet tube, said method comprising: connecting the inlet tube of said apparatus to a blood vessel of a patient and connecting the outlet tube of said apparatus to a vein of the patient; removing blood from the blood vessel of the patient; passing the removed blood through the absorbing means for absorbing interferon to thereby reduce the amount of interferon in the blood; and returning the blood to the vein of the patient, the improvement comprising; said absorbing means comprising a combined sorbent clearing agent having a first sorbent for absorbing interferon, a second sorbent absorbing transplantation antigens, a third sorbent for absorbing T-lymphocytes and a fourth sorbent for absorbing antibodies to transplantation antigens.
Claim 4
Dependent Claim
157 words
In a method of developing immunosuppression in a patient after the transplantation of foreign cells, tissues and organs using an apparatus having, in continuous fluid communication, an inlet tube, absorbing means for absorbing and thereby removing interferon from the whole blood, and an outlet tube, said method comprising: connecting the inlet tube of said apparatus to a blood vessel of a patient and connecting the outlet tube of said apparatus to a vein of the patient; removing blood from the blood vessel of the patient; passing the removed blood through the absorbing means for absorbing interferon to thereby reduce the amount of interferon in the blood; and returning the blood to the vein of the patient, the improvement comprising; said absorbing means comprising a combined sorbent clearing agent having a first sorbent for absorbing interferon, a second sorbent absorbing transplantation antigens, a third sorbent for absorbing T-lymphocytes and a fourth sorbent for absorbing antibodies to transplantation antigens.
Claim 5
Dependent Claim
178 words
In a method of developing immunosuppression in a patient after the transplantation of foreign cells, tissues and organs utilizing an apparatus having, in fluid communication with each other, an inlet tube, means for separating plasma from whole blood, absorbing means for absorbing and thereby removing interferon from the plasma, and an outlet tube, said method comprising: connecting the inlet tube of the apparatus to a blood vessel of a patient and connecting the outlet tube to a vein of the patient; removing blood from the blood vessel of the patient; separating the removed blood into blood cells and plasma; passing the plasma through absorbing means for absorbing interferon from the plasma to thereby reduce the level of interferon within the plasma; combining the plasma having a reduced level of interferon with the blood cells previously removed from the blood; and returning the combined blood cells and plasma to the vein of the patient, the improvement comprising: said absorbing means comprising a combined sorbent clearing agent having a first sorbent for absorbing interferon and a second sorbent absorbing T-lymphocytes.
Claim 6
Dependent Claim
178 words
In a method of developing immunosuppression in a patient after the transplantation of foreign cells, tissues and organs utilizing an apparatus having, in fluid communication with each other, an inlet tube, means for separating plasma from whole blood, absorbing means for absorbing and thereby removing interferon from the plasma, and an outlet tube, said method comprising: connecting the inlet tube of the apparatus to a blood vessel of a patient and connecting the outlet tube to a vein of the patient; removing blood from the blood vessel of the patient; separating the removed blood into blood cells and plasma; passing the plasma through absorbing means for absorbing interferon from the plasma to thereby reduce the level of interferon within the plasma; combining the plasma having a reduced level of interferon with the blood cells previously removed from the blood; and returning the combined blood cells and plasma to the vein of the patient, the improvement comprising: said absorbing means comprising a combined sorbent clearing agent having a first sorbent for absorbing interferon and a second sorbent absorbing T-lymphocytes.
Claim 7
Dependent Claim
194 words
In a method of developing immunosuppression in a patient after the transplantation of foreign cells, tissues and organs utilizing an apparatus having, in fluid communication with each other, an inlet tube, means for separating plasma from whole blood, absorbing means for absorbing and thereby removing interferon from the plasma, and an outlet tube, said method comprising: connecting the inlet tube of the apparatus to a blood vessel of a patient and connecting the outlet tube to a vein of the patient; removing blood from the blood vessel of the patient; separating the removed blood into blood cells and plasma; passing the plasma through absorbing means for absorbing interferon from the plasma to thereby reduce the level of interferon within the plasma; combining the plasma having a reduced level of interferon with the blood cells previously removed from the blood; and returning the combined blood cells and plasma to the vein of the patient, the improvement comprising: said absorbing means comprising a combined sorbent clearing agent having a first sorbent for absorbing interferon, a second sorbent absorbing transplantation antigens, a third sorbent for absorbing T-lymphocytes, and a fourth sorbent for absorbing antibodies to transplantation antigens.
