Fully implanted aphereter/dialyzers for intracorporeal blood purification
View Patent ↗A fully implantable intracorporeal blood purifier for patients with impaired, missing, or normal kidneys overwhelmed by a myeloproliferative disorder such as polycythemia vera, essential thrombocythemia, primary myelofibrosis, or chronic myelogenous leukemia. Functioning continuously or intermittently around the clock, the patient is spared the need to visit the clinic as frequently for treatment, and less severe renal dysfunction may allow the intervals between visits to be considerably extended if not eliminated. The intracorporeal blood purifier represents the extractive or negative component in a prosthetic disorder response system of which the positive component detects the need for and releases medication such as tyrosine-kinase inhibitors—imatinib, and interferon alfa-2b, and cooperates with the purifier to accomplish kidney functions not simply extractive, such as releasing hormones, calcitriol, sodium, and potassium into the blood, maintaining electrolyte, acid-base, and fluid balance, and furnishing small molecule amino acids and glucose by directly targeting the gut.
1 . An intracorporeal blood purifier for implantation configured to compensate for an inadequacy in renal function due to any disease and supplement normal renal function in the treatment of a myeloproliferative disease, said blood purifier comprising a succession of disease-related analyte separation magnets configured to be placed along and in perivascular relation to a substrate vessel, wherein the separation magnets are configured to extract and deliver said disease-related analytes into the urinary bladder, said disease-related analytes having been rendered magnetically susceptible by bonding to superparamagnetic carriers, wherein said blood purifier further comprises extractive windows configured to separate the blood flowing through the substrate vessel and the extraction magnets, said extractive windows including semipermeable membranes and resilient one-way slit valves.
2 . The intracorporeal blood purifier according to claim 1 wherein said blood purifier is configured to be applied to the inferior vena cava.
3 . The intracorporeal blood purifier according to claim 1 wherein said blood purifier is configured to be applied to the hepatic portal vein.
4 . The intracorporeal blood purifier according to claim 1 wherein said blood purifier is configured to be applied to the abdominal aorta.
5 . The intracorporeal blood purifier according to claim 1 wherein said blood purifier further comprises extractive magnets of different types and field strengths to include permanent and electromagnetic magnets, wherein the electromagnets are selectively energized.
6 . The intracorporeal blood purifier according to claim 1 further comprising batteries, wherein said batteries are rechargeable through a power supply plugged into an electrical outlet and by transcutaneous energy transfer through an implanted antenna.
7 . The intracorporeal blood purifier according to claim 1 where the analyte to be extracted from the bloodstream is a microbial pathogen, a toxin resulting from hepatic dysfunction, an antigen the product of autoimmune disease, or a material overproduction of any type of blood cell due to a myeloproliferative disease.
8 . The intracorporeal blood purifier according to claim 1 , wherein said blood purifier is configured to extract different types of disease-related analytes from the bloodstream simultaneously.
9 . The intracorporeal blood purifier according to claim 1 where the superparamagnetic carriers are configured to impart magnetic susceptibility and are bound to the disease-related analyte regardless of whether this bonding is due to an inherent affinity for the analyte or due to having been bonded to an intermediary substance with an inherent affinity for the disease-related analyte.
10 . The intracorporeal blood purifier according to claim 1 wherein said blood purifier continuously or intermittently without generating an experiential correlate of internal movement.
11 . An implanted automatic prosthetic disorder response system comprising:
an extractive, or negative component, wherein the extractive component is an intracorporeal blood purifier configured for implantation in the abdominopelvic and abdominal regions and configured to compensate for an inadequacy in renal function due to any disease and supplement normal renal function in the treatment of a myeloproliferative disease, said blood purifier comprising a succession of disease-related analyte separation magnets along and in perivascular relation to a substrate vessel, wherein the separation magnets are configured to extract and deliver said disease-related analytes into the urinary bladder, said disease-related analytes having been rendered magnetically susceptible by bonding to superparamagnetic carriers; and
a positive component,
wherein the positive component cooperates with the negative component by detecting the need for and directly targeting essential and curative substances to the sites of disease in immediate cooperation with the extractive component which is configured to extract different type disease-related analytes such as pathogenic, autoimmune, and supernumerary, from the bloodstream simultaneously; wherein said blood purifier further comprises extractive windows configured to separate the blood flowing through the substrate vessel and the extraction magnets, said extractive windows including semipermeable membranes and resilient one-way slit-valves.
12 . The implanted automatic prosthetic disorder response system of claim 11 , wherein said blood purifier functions continuously or intermittently without generating an experiential correlate of internal movement.
