摘要： A blood pump assembly has a balloon disposed at a distal region and a driveline disposed at a proximal region and is capable of being employed to provide mechanical circulatory support (e.g., counterpulsation). A blood pump support apparatus has a support structure with a head region and a tail region that is removably disposable in the blood pump assembly. When the support structure is disposed in the blood pump assembly, the head region is disposed within the balloon. When the blood pump assembly is implanted in the descending aorta and the support structure is disposed in the blood pump assembly, forces act on the balloon that would cause the balloon to roll or fold upon itself along an angle with respect to the balloon's longitudinal axis. The head region of support structure opposes these forces.

摘要： A percutaneous assembly is provided with a percutaneous sheath and a percutaneous dilator tip. The percutaneous sheath has a tubular wall extending to a distal end portion thereof and defines a lumen having an inner diameter. The percutaneous dilator tip includes a radially expandable member and an elongated control member. The radially expandable member is either removably engageable or fixedly attached to the distal end portion of the tubular wall and is also adjustable in an expanded and a contracted configurations. The elongated control member is disposed longitudinally along the tubular wall, positioned eccentrically relative to the lumen, and is operatively coupled to the radially expandable member for adjusting same in at least one of the expanded and the contracted configurations. A percutaneous sheath is also provided as kits.

摘要： In a method for intermittently occluding the coronary sinus, in which the coronary sinus is occluded using an occlusion device, the fluid pressure in the occluded coronary sinus is continuously measured and stored, the fluid pressure curve is determined as a function of time, and the occlusion of the coronary sinus is triggered and/or released as a function of at least one characteristic value derived from the measured pressure values. The pressure increase and/or pressure decrease per time unit each occurring at a heart beat are used as characteristic values.

摘要： A heart support device for circulatory assistance is disclosed. The device comprises a chamber body defining a chamber having an internal volume configured to be filled with blood. The chamber body has a first opening and the chamber is dimensioned such that the first opening and the chamber are fully disposed within a chamber of the human heart. A dynamic volume body is provided and configured to be inflated or deflated to alternately increase or decrease the interior volume of the chamber. A catheter comprising at least one lumen in fluid communication with the dynamic volume body is configured to deliver fluid to the dynamic volume body to inflate the dynamic volume body. A directional flow structure is configured to direct a flow of blood out of the chamber in a direction substantially aligned with a direction in which the catheter extends.

摘要： An apparatus for a heart of a patient having a cardiac assist device adapted to be implanted into the patient to assist the heart with pumping blood. The apparatus has a sensor adapted to be implanted into the patient. The sensor in communication with the cardiac assist device and the heart which measures native volume of the heart. The apparatus has a first cardiac assist device and a second cardiac assist device tuned to maximize blood flow to the body of the patient, while resting the heart so the heart may recover function. Alternatively, the sensor monitors the heart based on admittance while the cardiac assist device. Alternatively, the sensor monitors the heart based on impedance.

摘要： Disclosed is a device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart for a patient. The device includes an electrically controllable redistribution component attachable to the patient to provide redistribution of the cardiac output to increase supply to the brain and heart. The redistribution component, following a predefined reaction pattern based on an electrical signal, and computer means configured to: receive a patient data which identifies physiological and/or anatomical characteristics of the patent; and provide the electrical signal for the redistribution component based on the patient data or a standard response. The device may provide mechanisms to protect the aorta and the remaining anatomy of the patient from inadvertent damage caused by the disclosed device in any usage scenario of either correct intended usage or unintended usage. Also disclosed is a method for providing resuscitation or suspended state.

摘要： Systems and methods are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The system may include sensors to determine the degree of occlusion of the superior vena cava. The occlusion system may be used to reduce volume in a heart and facilitate a cardiac procedure. The occlusion system may be used to relieve an overloaded chamber during and/or after deploying a VAD.

摘要： A device to reduce left ventricle afterload in a target blood vessel in a mammal includes a cushion configured for positioning within a lumen of the target blood vessel and receipt of a fluid and configured to contract during systole and expand during diastole, a reservoir having a cavity for receiving the fluid, and a conduit extending between and fluidically coupling the cushion and the reservoir, whereby during use fluid in the cushion is transferred to the reservoir during systole and returned to the cushion during diastole. The cushion has an annular cross section defining a central lumen for blood flow and is configured for positioning in the lumen of the target vessel abutting an inner wall of the target vessel, whereby during use blood flow is directed through the central lumen of the cushion.
