METHOD AND SYSTEM FOR CONTROLLED HYPERTHERMIA
Methods and for treatment of cancer and other diseases including complications from late stage viral infections by inducing hyperthermia in a patient relying on withdrawing blood from the patient and returning the withdrawn blood to the patient to establish an extracorporeal flow circuit. Blood is heated by passing through the extracorporeal circuit at a controlled rate until a target body core temperature in is achieved. Usually, the blood will be subjected to a continuously re-circulating dialysis to balance electrolytes. Additionally, the blood will be subjected to a continuously recirculating regeneration through a carbon sorbent column where toxins and contaminants are removed. The blood temperature is maintained at the target blood temperature for a treatment period, and the blood is cooled after the treatment period has been completed. The method can also be effective in treating rheumatoid arthritis, scleroderma, hepatitis, sepsis, the Epstein-Barr virus, and patients with life threatening complications from other viruses, including the COVID-19 virus. A method for removing viruses from the blood supply in an external circuit is also presented.
SLURRY AND SOLUTION COMPOSITIONS
Slurries comprise liquid water, about 2% to about 70% ice by volume, and one or more additives affecting flowability and/or tonicity of the slurry. Solutions for making a slurry comprise liquid water and one or more additives affecting flowability of the slurry. Flowability of the slurry relates to ice particles capable of flowing through a cannula, such as a needle. The slurry is suitable for injection into subcutaneous fat of a human subject for removal of adipose tissue.
Systems and methods for providing zones of selective thermal therapy
The present disclosure describes for at least two zones of selective thermal therapy of the body. Three-port extracorporeal circuits are described that can be used to establish at least two zones of selective thermal therapy of the body. The example three-port extracorporeal circuit includes a branching section that provides for setting the temperature of blood injected into two different portions of the body at differing temperature levels, to provide. at least two zones of selective thermal therapy.
SYSTEMS AND METHODS FOR TREATING CANCER AND/OR AUGMENTING ORGAN FUNCTION
Systems, methods and devices for controlled sympathectomy procedures for neuromodulation in the treatment of subjects having neoplastic conditions are disclosed. Systems, methods, and devices for interventionally treating a cancerous tumor and cancer related pain are disclosed.
TRANSMYOCARDIAL JET PERFUSION DEVICE
The invention pertains to hardware and methods for direct injection, into the left ventricle of the heart of a patient or animal in cardiac arrest or in incipient cardiac arrest—using a 14-18 gauge cannula typically equipped with a retractable trocar—of an adequate amount of chilled saline or cryoprotective solution to create flow of chilled blood through the two carotid arteries, the two vertebral arteries, and the brain, to cool the brain or other vital organs. Generally, enough saline or cryoprotective solution is injected under high enough pressure to create a 30% baseline common carotid blood flow. The cannula arrangement with coordinated sharpened-tip retractable trocar, together with its surrounding flexible and rigid shield(s), diaphragm and stopcock(s), provides a sterile, self-sealing system suitable for use either in “the field” or in a hospital setting.
Heat exchange system for patient temperature control with easy loading high performance peristaltic pump
A peristaltic pump has an arcuate raceway wife a partially concave inner surface extending through an arc of at least one hundred eighty degrees (180°). The are defines a midpoint, and a rotor faces the inner surface of the raceway and is both rotatable relative to the raceway and transitionally movable relative to the raceway between a pump position, wherein the rotor is spaced from the midpoint a first distance, and a tube load position, wherein the rotor is spaced from the midpoint a second distance greater than the first distance. A rotor motor is coupled to the rotor to rotate the rotor and rollers arranged on the rotor to contact tubing disposed between the rotor and the raceway when the rotor is in the pump position. A loading motor moves the rotor toward and away from the raceway.
System and Method for Management of Body Temperature
A system and method for adding or removing heat from a heat exchange fluid circulating between an external heat exchanger and an intravascular heat exchange catheter is described. The system includes a two stage cooling system providing for a high rate of cooling in one stage and a lower rate of cooling in a second stage. Both stages may be used to provide maximal cooling while the second stage is used to provide improved control of the cooling rate as a target temperature is approached. The second stage may also be used to provide heat to the heat exchange fluid.
Proximal Mounting of Temperature Sensor in Intravascular Temperature Management Catheter
An intra vascular temperature management catheter incudes a shaft through which working fluid can circulate to and from a proximal location on the shaft. The catheter extends from a connector hub. At least one heat exchange member is supported by a distal part of the shaft or other part of the catheter to receive circulating working fluid from the proximal location. A temperature sensor is supported on the catheter for generating a temperature signal representative of blood temperature to a control system. The temperature sensor includes first and second conductive leads having respective first and second distal segments on or in the catheter shaft. The first and second distal segments are arranged to be in thermal contact with blood flowing past the catheter when the catheter is disposed in a blood vessel of a patient. Also, the temperature sensor includes a joining body connected to proximal segments of the first and second leads. The joining body may be supported in the hub or in another location proximal to the first and second conductive leads.
Systems and methods for selective auto-retroperfusion along with regional mild hypothermia
Systems and methods for selective auto-retroperfusion along with regional mild hypothermia. In at least one embodiment of a system for providing a retroperfusion therapy to a venous vessel of the present disclosure, the system comprises a catheter for controlling blood perfusion pressure, the catheter comprising a body having a proximal open end, a distal end, a lumen extending between the proximal open end and the distal end, and a plurality of orifices disposed thereon, each of the orifices in fluid communication with the lumen, and at least one expandable balloon, each of the at least one expandable balloons coupled with the body, having an interior that is in fluid communication with the lumen, and adapted to move between an expanded configuration and a deflated configuration, and a flow unit for regulating the flow and pressure of a bodily fluid, and a regional hypothermia system operably coupled to the catheter, the regional hypothermia system operable to reduce and/or regulate a temperature of the bodily fluid flowing therethrough.
