    摘要: An integrated disposable set for dialysis or ultrafiltration treatment of blood is disclosed that includes a memory “key” chip. The key contains information relating to the set, including calibration for sensors, model and date of manufacture and a proprietary secret code to prevent unauthorized duplication of a circuit. The key is activated when treatment of a patient begins to prevent reuse of the set and a delay in use of the set that is too long. Patient data and operational information can be stored in the key during treatment. The key can be returned to the manufacturer or entered into hospital database for analysis. The key is preferably an EEPROM chip that can be embedded in an integral circuit sensor or a separate plug in device, such as a code card.

    摘要: A method for treating congestive heart failure (CHF) has been developed that restores kidney renal functions by artificially perfusion of at least one kidney. The kidney is perfused with the patient's blood or other suitable perfusion fluid. A catheter inserted into the aorta of the patient has a distal end that supplies the perfusion fluid into a renal artery of the patient. The catheter may be coupled to an implanted blood pump or to an external supply of perfusion pressure. The restoration of kidney function assists the heart by removing excess fluid, urine and toxin from the patient, and by normalizing the patient's renin-angiotensin system and other neurohormonal substances. The method is applicable to treat chronic and acute CHF.

    摘要: A method is disclosed for inflating an inflatable vest to assist the heart in patients suffering from heart failure. The inflation of the vest is synchronized with on-set of the systole phase of the heart, when the left ventricular compresses to force blood out of the heart and through the aorta. The inflated vest compresses the patient's chest and increases the intrathoracic pressure. This increase in pressure assists the heart in moving blood out of the heart and through the aorta. In addition, the vest is arranged to leave the patient's abdomen free of restraint so that the increase in intrathoracic pressure due to the vest moves blood into the abdomen, and to allow the abdomen to dynamically recoil in response to the vest inflation. In addition, ECG signals from electrodes applied to the patient are processed to trigger the vest inflation in real time with the current heartbeat cycle, such that the vest inflation is triggered when the heart begins to contract. A controller provides an adjustable signal blanking period to avoid noise components following the QRS complex.

    摘要: A method and apparatus for controlling blood withdrawal and infusion flow rate with the use of a pressure controller. The pressure controller uses pressure targets based upon occlusion limits that are calculated as a function of flow. The controller has the ability to switch from controlling withdrawal pressure to controlling infusion pressure based upon the detection of an occlusion. The controller distinguishes between partial and total occlusions of the withdrawal vein providing blood access. Depending on the nature of occlusion, the controller limits or temporarily reverses blood flow and, thus, prevents withdrawal vessel collapse or reverses blood flow to quickly infuse blood into the vessel without participation from operator.
