According to some embodiments, a system may treat blood outside the body of a patient. The system may include at least one toxin removal system configured to process blood from at least two places on the patient's body at a rate, for example, of at least 0.5 liters per minute. The system may be configured to raise the pH level of the patient's blood by introducing a fluid at rate of at least 9 liters per hour.

Apparatus for removing chemotherapy compounds from blood

A filter apparatus for removing small molecule chemotherapy agents from blood is provided. The filter apparatus comprises a housing with an extraction media comprised of polymer coated carbon cores. Also provided are methods of treating a subject with cancer of an organ or region comprising administering a chemotherapeutic agent to the organ or region, collecting blood laded with chemotherapeutic agent from the isolated organ, filtering the blood laden with chemotherapeutic agent to reduce the chemotherapeutic agent in the blood and returning the blood to the subject.

A negative-balanced isolated pelvic perfusion method, in which a drug is administered into the closed pelvis while keeping the volume of suction from the vein larger than that of injection into the artery, does not require allogeneic blood transfusion. A perfusion device is for recovering a liquid containing a drug and/or blood from a tube connecting to the inferior vena cava and for injecting the liquid obtained into a tube connecting to the artery, provided with a unit for closing the inside of the pelvis by including a unit for blocking the artery from the heart to the pelvis, a unit for blocking the inferior vena cava from the pelvis to the heart, and a unit for blocking a blood flow from the pelvis to the lower limbs. The perfusion device is provided with a pelvic perfusion unit equipped with a reservoir, an autotransfusion unit, and a dialysis unit.

Recovery catheter assembly and method

A recovery device assembly comprises an actuator element and a mechanically radially expandable and contractible recovery device operably connected to the actuator element is provided. The recovery device has proximal and distal toroidal balloon blocking elements and a central portion between the blocking elements. The recovery device is at least partially placeable in a first, radially collapsed configuration and in a second, radially expanded configuration by manipulation of the actuator element. When in the second, radially expanded configuration, the proximal and distal blocking elements have radial dimensions greater than the radial dimension of the central portion thereby at least partially defining a collection chamber at the central portion. Also provided are methods of isolating an organ and recovering blood from an organ that use the recovery device assembly provided.

Localized therapy delivery and local organ protection

A system for perfusing a localized site within a body includes a catheter assembly having a venous access line that is adapted to deliver perfusate to the localized site, a venous or arterial drainage line adapted to drain perfusate from the localized site, and an occlusion device adapted to prevent some or substantially all physiological blood flow between the localized site and the systemic circulation of the body during and in the course of perfusing and draining perfusate to and from the localized site. The system may include a blood circuit associated with the catheter assembly to facilitate blood conditioning for use as the perfusate, in the course of a controlled perfusion and/or drainage of untreated, treated, or inactivated treated blood to and from the localized site. A delivery machine may control the blood circuit and catheter assembly in order to both deliver perfusate to, and drain some or all perfusate from, the localized site in a manner that provides perfusate to substantially only the localized site.

EXTRACORPOREAL CLEARING TRAPS BASED ON INVERSE ELECTRON DEMAND DIELS-ALDER CYCLOADDITION FOR (PRE)-TARGETED THERAPY AND DIAGNOSTICS

The present invention provides extracorporeal removal of targeting vectors applied in pretargeted therapy and diagnostics in animals and humans. The method and the means for extracorporeal removal of the targeting vectors is based on binding agents with inverse electron demand Diels-Alder (IEDDA) cycloaddition reactivity. The targeting vector comprises a therapeutic agent, a diagnostic agent or a theranostic agent and a chemical entity with IEDDA reactivity whereas the extracorporeal means comprises a column with a biocompatible solid support to which a chemical entity with complementary IEDDA reactivity is attached.

DEVICES AND METHODS FOR RECOVERING DISEASE-CAUSING TOXIC CONSTITUENTS IN THE BLOOD

The present disclosure relates to non-hemolytic blood compatible devices and methods for capture, enumeration, removal of disease-causing agents from the blood and for the treatment of the cancer patients. The said devices incorporating non-hemolytic compositions are useful for removing disease-causing agents ‘ex vivo’ from cancer patient's blood to prevent/delay the proliferation of cancer. The devices retain disease-causing agents in particular Circulating Tumor Cells (CTCs), allowing the passage of other blood constituents retaining the viability of hematopoietic cells.

IN VIVO POSITIONABLE FILTRATION DEVICES AND METHODS RELATED THERETO
20220338972 · 2022-10-27 ·

In vivo positionable filtration devices are provided that filter one or more therapeutic agents in blood flowing in a blood vessel. The filtration devices include an elongated member and a filtering component coupled to the elongated member. The elongated member and the filtering component are dimensioned for positioning within a blood vessel of a human or non-human animal. Further, the filtering component includes a filtration material to filter the one or more therapeutic agents from blood. Methods of in vivo filtration of one or more therapeutic agents are also provided. The methods include positioning a filtration device in a blood vessel of a body of a human or non-human animal, and administering a therapeutic agent upstream from the target tissue site to direct flow of the therapeutic agent to the target tissue site and then to the filtration device. The filtration device is positioned downstream from a target tissue site.
