Combined catheter system for IABP and determination of thermodilution cardiac output
An intro-aortic balloon catheter system and method for determining cardiac output with the system including a distal end for insertion into an aorta and a proximal end opposed to the distal end, a balloon portion in proximity to the distal end which repeatedly expands and contracts so as to assist the pumping action of the heart, a catheter tube connected to the balloon portion with the catheter tube having a lumen introducing a pressurized gas into the balloon portion and leading the pressurized gas out from the balloon portion and a temperature sensor attached to the catheter tube and being electrically coupled to a connector at the proximal end of the catheter tube. The method includes inserting the temperature sensor into a lumen of the intra aortic balloon catheter system, advancing the temperature sensor until it projects freely into the aorta, injecting an injectate of a temperature different to that of the temperature of the patient's blood into the central vein of the patient, measuring the blood temperature profile versus time by means of the temperature sensor and calculating cardiac output and optionally the derived variables from the measured temperature profile.

Methods of Transvascular Retrograde Access Placement and Devices for Facilitating the Placement
The invention relates to methods of transvascular retrograde access placement into a central blood vessel and to devices that facilitate these methods. The method includes positioning a vascular catheter within the vessel such that its distal end faces a desired exit site on the vessel wall, passing a penetrating device from the catheter through the vascular exit site and skin of the patient; and passing a secondary vascular catheter through the exit site and into the central blood vessel. In another aspect, the method includes penetrating outward from within the vessel to form a pass-through site on a wall of the vessel that exits the patient; and placing the vascular access device into the vessel through the pass-through site. Typical vessels that may be accessed include central veins, but may include other veins as well as arteries. Devices that facilitate the method include a stiff intravascular guidewire with a distally-mounted penetrating device such as a needle, and a two-channel vascular catheter with an angled tip.

Method and device for intravascular plasma fluid removal
InactiveUS6869412B2Semi-permeable membranesSolvent extractionUltrafiltration (renal)External catheter
Plasma fluid removal is needed in a variety of clinical conditions including congestive heart failure and moderate renal insufficiency. In order to avoid the problems inherent in extracorporeal ultrafiltration methods, the present invention removes fluid using an intravascular or intracorporeal dual-lumen catheter. Plasma fluid is driven across a semipermeable membrane, as in an in vivo vascular catheter. Suboptimal intracatheter flow, luminal collapse, erratic high transmembrane flow with nonhomogenous caking and clotting of the external catheter surface are all avoided by inducing pressure gradients across the wall by means of osmotic forces instead of negative pressures induced by hydraulic pumps. Osmotically induced fluid flow would tend to keep the lumena slightly distended and thereby simplify the fluid delivery systems. Osmotic gradients are maintained by utilizing dual lumen catheters typically placed in large central veins, and attached to pumps supplying high osmolality sterile solutions (such as dextrose or other sugars). Such a sealed system using readily available sterile sugar solutions and biocompatible catheter substrate would be extremely safe.

Central venous catheter assembly for measuring physiological data for cardiac output determination and method of determining cardiac output
ActiveUS8016766B2Reduce intrusionConvenient and accurateVolume/mass flow measurementCatheterBlood flowCatheter device
The central venous sensor assembly comprises a catheter body with several proximal ports. The catheter portion placed in the vena cava superior is equipped with a proximal flux measurement unit, and the catheter portion placed in the vena cava inferior is equipped with a distal flux measurement unit. A first input channel supplies a measurement signal indicative of a flux vp to the evaluation unit from which the latter calculates a blood flow in the vena cava superior. Likewise, a second input channel supplies a measurement signal indicative of a flux vd to the evaluation unit from which the latter calculates a blood flow rate in the vena cava inferior. Due to continuity, the sum of the flow rates in the upper and lower central veins corresponds to the flow rate through the right heart and in the pulmonary artery and thus to cardiac output.

Managing Cross-contamination in Blood Samples Withdrawn from a Multilumen Catheter
InactiveUS20090048576A1Accurate measurementIncrease opportunitiesMedical devicesCatheterBlood withdrawalBlood stream
The present invention comprises methods and apparatuses that can provide accurate measurement of glucose or other analytes from a multilumen catheter in the presence of infusion of substances, including glucose. Examples of “multilumen catheters” include central venous catheters having multiple lumens, midline catheters having multiple lumens, multiple catheters configured or emplaced such that their lumens are in proximity to each other, and, in the case of indwelling analyte sensors, a catheter with a lumen for infusion and an indwelling sensor spaced apart from the infusion lumen. For blood withdrawal, anti-cross contamination controls can prevent the entrainment of blood which might be contaminated with feeding fluids or medications that are administered through other lumens within the catheter and in proximity of the blood sampling port. Cross contamination can occur under various situations, and is known to occur when the patient is connected to a ventilator. The ventilator cyclically raises the intra-thoracic pressure and diminishes blood flow rate in the central veins returning to the heart. The diminished flow can increase the chances for cross-contamination when additional lumens are introducing fluids during a draw sample.

Transvascular diaphragm pacing systems and methods of use
Transvascular diaphragm pacing systems (TDPS) and methods are disclosed for providing respiratory therapy to a patient. The TDPS can provide rapid insertion and deployment of endovascular pacing electrodes in critically ill patients who require intubation and invasive PPMV in order to support the physiological requirements of the human ventilatory system. The systems and methods make best use of the contractile properties of the diaphragm muscle and prevent muscle disuse and muscle atrophy. This can be carried out by engaging the phrenic nerves using patterned functional electrical stimulation applied to endovascular electrodes that are temporarily and reversibly inserted in central veins of the patient, such as the left subclavian vein and the superior vena cava. The TDPS can be designed to seamlessly interface with any commercially available positive-pressure ventilatory assistance / support equipment such as is commonly in use in hospital intensive care units (ICU) for treating critically ill patients with breathing insufficiencies, pain, trauma, sepsis or neurological diseases or deficits.

In emergency, the optimal method for building an emergency transfusion channel is intra-bone marrow transfusion which ensures that a medicament and liquid transfused into the marrow cavity can quickly and effectively enter blood circulation. The time for the medicament administrated from intra-bone marrow to enter systemic circulation is basically the same as that for the medicament which is administrated from central veins to enter the systemic circulation, but is quicker than that for the medicament which is administrated from peripheral veins to enter the systemic circulation. For criticalpatients who cannot be treated by regular vein puncture, the intra-bone marrow transfusion may be a first choice instead of the traditional venous transfusion is quick, safe and effective rescue technology and saves precious time for life rescue. In the invention, a medullo-puncture needle is penetrated into the marrow cavity by a mechanical energy releasing device to feed the medicament and the liquid into the veins.
