  • Patent number: 6632189
    Abstract: A device for supporting and displaying interrelated medical components, such as cardiopulmonary bypass circuit components. The device includes a rigid or flexible chassis having openings therein for receiving the components. A plurality of retainers, such as straps, hooks, or tabs, are provided adjacent the openings for releasably securing the components therein. The chassis may be formed of a thin, flexible polymer sheet having tabs cut therein and adapted to be bent out of the plane of the sheet for securely retaining the various components. The pre-arrangement of the components in close proximity greatly simplifies the task of setting up a particular medical circuit, and reduces the potential for error. For cardiopulmonary bypass circuits, the support device enables the tubing lengths to be reduced, thus reducing the prime volume of the circuit. The chassis is provided with apertures for mounting on rods in the operating room, which rods may extend from the operating table.

  • Patent number: 6632192
    Abstract: Segmental edema is treated by inserting a plasma extraction filter device in a major vein of a body segment or servicing the body segment containing the edemic tissues, and inserting a return catheter in a major artery of the body segment affected or feeding the body segment from which plasma is extracted. Blood plasma and plasma proteins extracted from the edemic body segment through the plasma extraction filter fluids are directed to an ultrafiltration apparatus where plasma water is separated from the plasma proteins. Plasma proteins are returned to the body segment from which the plasma was extracted via the return catheter in the major artery of the subject body segment.

  • Patent number: 6633776
    Abstract: Location-specific diagnostic information is detected and recorded by the cardiac stimulation device for subsequent display using the external programmer device. The diagnostic information includes location-specific event records, counters and IEGM signals. The event records include event codes that distinguish among events occurring in the four chambers of the heart, such as sensed or paced events occurring within the left or right atria or the left or right ventricles. The counters separately count events occurring within the chambers of the heart. The IEGM signals are separately detected within the four chambers of the heart using a multiple sensing lead arrangement. The location-specific event records, counters and IEGM signals are ultimately transmitted to the external programmer, which displays graphic representations of the diagnostic information. The event records are displayed using distinct event marker icons which distinguish among the four chambers of the heart.

  • Patent number: 6630107
    Abstract: The equipment comprises an impulsion pump (5-5′) with a displaceable piston (7), that adopts a bellows shape, located in the inside of the same, the chamber of the pump receiving the patient's venous blood from a reservoir (4). In the communication (16) between the reservoir and the chamber a float valve (17) has been provided for, a valve that closes the passage when the piston (7) impels the blood through a nozzle (15), passing through a valve (22), then through a heat exchanger (28) and then through an oxygenator (29) from which the oxygenated blood is sent once again to the patient. The shaft (9) of the nozzle (7) is operated by a mechanism (14) that transforms the rotating and alternate movements of a servomotor (12) into linear movements, the operation of this servomotor (12) being controllable by means of a computerized console, permitting a pulsatile blood flow to be provided with adjustable flow and frequency.

  • Patent number: 6623443
    Abstract: Stenosis in a blood access circuit (graft, fistula) or in an extracorporeal circuit are detected by monitoring pressure pulses in the extracorporeal circuit created either by the heart or by the peristaltic blood pump of the extracorporeal circuit. By monitoring pressure pulses created by the. peristaltic blood pump loss of occlusion of the blood pump can be detected. Measurement of the pressure pulses is done either with sensors already built into the blood treatment equipment or, according to the invention, with sensors mechanically coupled to the wall of the blood tubing. The deviation of a pressure pulse amplitude proportional signal from a predetermined value indicates stenosis or loss of occlusion, respectively.

  • Patent number: 6620382
    Abstract: A method to treat cancer uses ultrapheresis, refined to remove compounds of less than 120,000 daltons molecular weight, followed by administration of replacement fluid, to stimulate the patient's immune system to attack solid tumors. In the preferred embodiment, the patient is ultrapheresed using a capillary tube ultrafilter having a pore size of 0.02 to 0.05 microns, with a molecular weight cutoff of 120,000 daltons, sufficient to filter one blood volume. The preferred replacement fluid is ultrapheresed normal plasma. The patient is preferably treated daily for three weeks, diagnostic tests conducted to verify that there has been shrinkage of the tumors, then the treatment regime is repeated. The treatment is preferably combined with an alternative therapy, for example, treatment with an anti-angiogenic compound, one or more cytokines such as TNF, gamma interferon, or IL-2, or a procoagulant compound. The treatment increases endogenous, local levels of cytokines, such as TNF.

  • Patent number: 6616623
    Abstract: A system is presented for correction of a patient's biological fluid, such as his blood, lymph or spinal fluid, containing various low-, medium- and high-molecular toxins. The system comprises an extracorporeal flow line in the form of a flexible tube interconnected between outlet and inlet means attached to appropriate location(s) on a patient's body. A small amount of the biological fluid, i.e., substantially not exceeding 100 ml, substantially continuously flows through the tube, and is mixed with magneto-conductive particles capable of adsorbing the various toxins. An obtained mixture of the biological fluid with the particles passes through a magnetic field region, and substantially all of the magneto-conductive particles are retained therein. Particle-free biological fluid is then returned into the patient's body through the inlet means.

  • Patent number: 6613020
    Abstract: A novel device and method for applying two or more liquid components, for example fibrin sealant-forming components, comprises sources of the components fliud communication with, but remote from, an applicator for delivering the components to a desired site. Preferably, the user of such a device and method can actuate the application of the components by providing a signal to a controller which dispenses components from their sources to, and out of, the applicator.
