摘要:
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.

Provided is a method for enhancing an immune response in a mammal to facilitate the elimination of a chronic pathology. The method involves the removal of immune system inhibitors such as soluble TNF receptor from the circulation of the mammal, thus, enabling a more vigorous immune response to the pathogenic agent. The removal of immune system inhibitors is accomplished by contacting biological fluids of a mammal with one or more binding partners such as TNF&agr; muteins capable of binding to and, thus, depleting the targeted immune system inhibitors from the biological fluids. Particularly useful is an adsorbent matrix composed of an inert, biocompatible substrate joined covalently to a binding partner, such as a TNF&agr; mutein, capable of specifically binding to a targeted immune system inhibitor such as soluble TNF receptor.

The invention relates to use of pulmonary catheters in methods for delivering a composition to the lung in a non-surgical, percutaneous approach by utilizing the pulmonary vasculature (i.e., the pulmonary arteries and veins). The invention also relates to methods allowing for the lung-specific delivery of a composition, as well as a catheter that includes a deployable arm.

An apparatus, a kit and a method for treating a tumor in an extremity of a patient. The method first includes: providing a first catheter (9) designed, sized and dimensioned for percutaneous insertion into the specific vein or portion of vein of the extremity receiving the blood from the tumor, including a plastic tube having a cranial end and a caudale end. The plastic tube defines a main lumen for outflow blood, two balloons (11, 12) spaced apart about the plastic tube and bonded thereto for inflation thereabout. One balloon is contiguous to the cranial end wherein the balloons (11, 12) are sized and spaced on the plastic tube sufficient that when inflated, they have sufficient size and spacing therebetween to substantially block the flow of blood in the vein and to substantially isolate outflow from the tumor to other portions of the vein; fenestration (104) in the plastic tube between the balloons (11, 12) to the main lumen; second, and third lumina within the plastic tube. The second lumen connects to one of the balloons, the third lumen connects to the other of the balloons for effecting inflation or deflation of the balloons; the cranial end of the plastic tube being closed to substantially all inflow of blood.

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.
摘要:
The present application provides a device for the simultaneous or the separate perfusion and occlusion of a vessel comprising a body having a distal end, a proximal end, a single lumen (66, 80) extending between the proximal end and the distal end, and at least one opening (63,72) which is in fluid communication with the lumen for delivering a therapeutic treatment to a vessel; and at least one expandable balloon (65,70,81) coupled with the body of the device, said balloon is provided with an interior which is in fluid communication with the lumen of the device through at least one opening (68, 69, 70), said opening is provided with at least one valve (71) which is movable from a closed position, in which fluid communication of the lumen with the interior of the balloon is prevented, to an open position in which the lumen is in fluid communication with the interior of the balloon.

摘要:
Tumors in the body of a patient are studied in situ by a monitor (12), such as computer assisted tomography, X-ray or the like, while optimal flow paths through the tumor area are established. A catheter (52) with a suction lumen (50) and an infusion lumen (25), with seals (22, 56) associated with each, is placed in the patient's vein near the tumor. Flow is then sealed in the vein with the infusion seal (56). A carrier medium dye is injected into the tumor at selected flow rates and differential pressures. Flow of the dye through the tumor is observed on the monitor (12) to determine optimal retrograde perfusion paths through the tumor for the selected flow rates and differential pressures. Once the optimal perfusion paths are noted, microspheres with active ingredients, such as chemotherapy, can be selectively perfused through each of the paths in the tumor at desired flow rates, pressures and active ingredient dosages.
